Andrew James


Andrew JamesSunInfo is sad to have to report the untimely death in October 2019 of an experienced, accomplished and well liked British diallist, Andrew James FRSA HonMBHI.  Born in Somerset, Andrew learnt from his father, before he went to school, that skilled hands could, with simple tools, transform raw materials into useful and beautiful objects.

After studying both Natural Sciences and Computer Science at Cambridge, he joined the Computing Development Department of the Central Electricity Generating Board and was soon given the task of creating software for a revolutionary new meter – the precursor of today’s smart meters. He later spent 25 years as chief scientist for a meter manufacturer.

While never his career, horology always remained his true passion and from 2000 to 2016 he chaired the Wessex BHI Branch. Later he was elected to be the Master of the Worshipful Company of Clockmakers. He was installed at a special ceremony at Panter-Stainers’ Hall, London, followed by a Thanksgiving Service at St James Garlickhythe Church.

Andrew combined a love of calligraphy and carved lettering with a strong interest in sundials, and with an interest in accurate assessments of the Equation of Time and, for the BSS Registrar,  an invaluable interest in resolving the several uncertainties of dial recording not least the resolution of the long standing problem of whether or not there was a dial in Woolfardisworthy in Devon. After successive searches by BSS Members over several years had (almost alternately) found the dial or reported its loss, it was Andrew who discovered that almost unbelievably to mere mortals, there are two villages in Devon called Woolfardisworthy one with a dial and one without!

The Society benefitted from yet another of Andrew’s hidden skills when he generated the then new index of Bulletin Articles. Later he won one of the Society’s prizes for sundial design and construction.

Andrew will certainly be remembered as one of those few people who left this world better than he found it.  He will be sorely missed.


BSS Accounts Reporting Performance 2018 & 2019 The Charity Commission reports on its web BSS Filing Performance to datesite that the 2018 results were only filed at nearly the last minute. It took about ten months - virtually the permitted limit - for the 2018 accounts and report to be filed.  The 2019 accounts for the year ending 31st December 2019 were finally filed in August 2020. Click on the image for the reporting performance last year. The Accounts for 2019 can be seen HERE. They show  a fall in assets and a large conference expense.

Manipulation of Satellite Data? Now it seems that even the published satellite data regarding climate change is being manipulated. Just see this latest discovery.  Then see more proof here about the same with temperature data.  Can you ever imagine Richard Feynman or Albert Einstein agreeing to do this?

Is Pluto really a planet after all? Scientists are now coming to argue that the official definition of a planet is ‘sloppy’ and that Pluto should never have been downgraded in the 2006 review by the IAU (International Astronomical Union). The 2006 definition was devised (it seems) more to stop too many planets being declared than ever it was to provide a sensible definition. The discovery in 2005 of Eris, a body more massive than the smallest then-accepted planet, Pluto forced the issue and the new definition thereafter has required a 'true' planet to be roughly spherical, orbit the sun and to clear its orbit. Pluto and Eris fail, not surprisingly, to clear their part of the Kuiper belt and in any case University of Central Florida’s planetary scientist Philip Metzger points out that strictly speaking no planet clears its orbit not least because of the newly discovered dust rings in the orbits of Mercury and Venus. Maybe the definition of a planet should be set by diameter and whether or not a sundial can be constructed for it anywhere on its surface?

Time Lapse Videos of sundials and shadows? YouTube is an excellent source of interest where sundials are concerned.

If you have ever wanted to see a time lapse video of shadows moving with time and/or with the seasons and related aspects do take a look here.


A Form of Violence? Some climate scientists still struggle to cope with people who disagree. So some time back, Cliff Mass – a Professor of Atmospheric Sciences at the University of Washington as well as a radio weatherman – decided to write something about the wildfires in California, and in particular, the question of whether climate change had played a role. At the end of a long analysis of climatological trends in the area, he drew his conclusions:

Was Global Warming A Significant Factor in California's Camp Fire? "The Answer is Clearly No". [See full article here]

Now take a look at some of the replies! And you thought scientists were logical?

Reality finally dawns about urban warming! Now actually verified by NOAA (the  National Oceanic and Atmospheric Administration of the USA).  Poor weather station siting leads to artificial long term warming.  How long has it taken to get to this point?  But here we really are - let all real scientists rejoice. All the links are here.
See "Impacts of Small-Scale Urban Encroachment on Air Temperature Observations", Ronald D. Leeper, John Kochendorfer, Timothy Henderson, and Michael A. Palecki HERE


Does the NYTimes really hide the truth about warming? Is this interesting analysis of how the New York Times reports temperature changes since the 1960s really as fraudulent as this article suggests? Then see this about other possible frauds.

Mike Shaw's Web Site has sadly been discontinued but some of Mike's excellent contributions to dialling can still be found elsewhere on the Internet.  One such is his 'Really Useful Device', a slide presentation showing ways in which you may construct a Diallist's Companion for your own location.  The presentation is clear and well worth looking at. It may still be found for download as a PDF (12.5MB) at
Then click on the Orange button in the upper left of the screen marked "DOWNLOAD PDF (12.3MB)". The file will then be downloaded to your PC. Get it whilst you can!!


Jim Tallman's Artisan Sundials page is well worth a look.

Artisan sundials are specially designed and constructed to provide accuracy as well as a genuine sense of presence in time and space. They are authentic scientific instruments that are carefully constructed and capable of telling very accurate time.
There's more here


Jay Campbell's New Dial Have a look at Jay Campbell's new sundial in New Mexico USA. It (like his accompanying website) is just nearing completion but there will be an article about it in the December issue of Sky & Telescope magazine, available in late October.

See more about this venture

"Have you ever purchased a delightful sun dial for your garden, but found it does not work? No problem". That is the encouraging beginning of an excellent article in PDF format  that discusses how to take a store bought dial and then adjust it so it will work for you. Entitled "REVERSE ENGINEERING STORE-BOUGHT GENERIC DIALS" It is just one extract from the fascinating book "ILLUSTRATING TIME'S SHADOW" by Simon Wheaton-Smith whose website (already mentioned elsewhere on this page) is an incredible resource for all diallists.

The National Oceanic & Atmospheric Administration of America (NOAA) is well known for its research into greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, surface radiation, and recovery of stratospheric ozone. In Sept 2018 it released a report claiming that the summer of 2018 was the fourth hottest on record in the US, and it went on to claim that this summer was just as hot as 1934. Yet, when this claim is examined it turns out that it may not be correct. Listen to a US scientist's analysis of this and read about some of Heller's other concerns about climate science misinformation today. Form your own opinion.

Things to See and Do!

An On-line Sundial Register. There's an interesting browse to be had of  the Sundial Website that is operated by Dennis Cowan of Fife.  As well as giving an excellent introduction to the sundials of Scotland, the site includes a 92 page Sundial Register of dials known to him, (not just those in Scotland), five sundial trails, several safaris and seven articles about dials and dialling. A really excellent site. Image used with permission

Have a look at Karen's Page!  Want to make a sundial and compass from your own fingers, a sundial and compass from an embroidery hoop. an origami sundial wristwatch. a horizontal sundial using only compass, straight edge and protractor or use your hand as a nocturnal or even make a Universal Capuchin sundial? This is the place to come!

SunInfo's Archive Pages. This, our main page, gets larger and larger as time goes by and of course the page would get slower to load. However, many of the stories, comments and information in it are still of interest even though they may not be recent.  Accordingly we archive most of the older entries so that little or nothing is permanently lost.  Our Archive Page 1 and, from 2018, our Archive Page 2 are available!!  Have a browse of them for yourself.

Interesting News, Articles & Links

Is the answer simply Scientific Apophenia - all along? Climate scientists are looking for evidence that supports the AGW hypothesis — and because they are looking for it, Kip Hansen believes they see it in everything. The evidence, so far, simply does not support the inference that the Earth’s climate is changing dangerously. Perhaps only persons suffering from Scientific Apophenia see dangerous climate change in the chaotic, random patterns of long-term climate metrics?

A visit to Windsor.. In 1998 Jane Walker and her husband Peter found an interesting booklet that led them to a viewing of the Queen's Dial in Windsor Castle.  The dial stands on the North Terrace with the Queen's private garden to one side and a splendid view over the town of Windsor to the playing fields of Eton on the other. The gnomon is beautifully engraved and carries the King's monogram "CR" intertwined so that the initials can be read from either side.  Read all about Jane's experience

Peter Daykin's Derbyshire Sundials Page is well worth a visit - not least because it includes such examples as a cross dial and of course the famous Eyam Dial.  The website includes details of many Derbyshire dials and even includes three sundial calculators. On almost every page there is a description of the location as well as of the dial. A delight to peruse.

Some Complications of Dial Refurbishment as considered prior to the restoration of the Queens' College dial in 2006/7. This is an interesting document which is well worth a read by those facing similar problems! Includes the oldest known photograph of the dial and consideration of the several issues that remained after the previous repainting in 1971.

To read  the document click here: The Queens' Dial


Andrew Somerville's Interesting Letter of 1986 concerning the Queens' College Sundial in Cambridge was published in the BSS Bulletin in 1997 and those with an interest in dialling might like to read it again. One matter concerned the marking of the dial with the word Longitudo and whether or not there was an error in the dial's markings. Andrew was of course the first Chairman of the Society and this correspondence was dated 1986 only a few years after the Society's formation. Read the correspondence here

The John Churchill Collection! SunInfo is delighted to be able to present a collection of just some of the photographs of dials that former BSS Trustee John Churchill and his wife took during his lifetime.  They represent an eclectic selection of his interests and as well of course, a valuable and lasting record of the condition of the dials up to the time of the millennium.

The Dial of William Hughes of Bryngola. In what can only be described as a tour de force of investigation, John Davis recently studied a dial dated 1775 which was made for William Hughes of Bryngola in Llangwyllog, a small village and ancient parish in the centre of Anglesey, Wales. The church of St Cwyllog (illustrated) still bears memorials to the family to this day. John deduces that the elaborately engraved dial may have been made for Hughes by one of the Owen dynasty of clockmakers perhaps using components from the clockmaking area around Prescot in Lancashire.  A fascinating BSS article which may be read at John's website at this link Dial of William Hughes.

A lovely selection of Italian sundials Here is a link to a whole load of images of Italian sundials that have been taken by photographer Darek Oczki in the areas of Umbria, South Tuscany and Rome between August 2010 and September 2018.  Some (under the Activity sidebar) are earlier.

Great Circle was thought to be back!! Those diallists who liked to rely on Great Circle Studio's solar data calculator to obtain or print off a table of solar parameters at any time interval have recently been troubled by its apparent absence. Then it was thought to be found at Great Circle Studio Solar Data . However, it does not 'work', the server side links are not made.  But, after contact, the website owner claimed to be 'on the case'. In the meantime you could try MIDC SPA  Calculator (max intervals of one hour) or Sun Ephemeris,

The Sundials at New College Oxford. In an interesting article Harriet James describes the dials that have existed at New College Oxford - the college that was 'new' in 1379 - and gives an interesting insight to her replacement of one that was on the Muniment Tower in 1696. 

Read the text of Harriet James' BSS Article in 2000 to know more about the Sundials of New College past and present.

 BSS Member Ian Maddocks has really started something by finding a whole load more dials that are apparently currently unknown to BSS!  In two messages to the International Sundial Mail List he announces his discovery that Twitter® and Instagram® contain many mentions of UK dials that are not recorded in the most recently published BSS Register of Dials - though of course some may be held on file by the Society's Registrar ready to be published next time.  Whatever, this is excellent news for all those interested in dialling. Not only that but Ian has combined a list of these on his Google drive.  They may be viewed here.  There is also a 'map' of their locations here.
Now with Graham Stapleton's help he has added even to this amazing number and with pics too

Newton's Sundial Courtesy of Ian Maddocks and the Objectivity YouTube channel we are able to see a short video clip which, after half way, shows one of the stone dials scratched by Isaac Newton into the walls of his home.  Click on the image for a larger picture,  Here to see the video and Here to see the record document of items like this from Newton's home.

The Mass Dials of Gloucestershire. Tony Wood, in a reprint from Gloucestershire History No. 21 (2007) pages 16-22, describes the many mass dials of Gloucestershire. Mass dials, or scratch dials, are mediaeval sundials found on churches. Chronologically they appear after Saxon dials (c650 — c1050) and before the present day's ‘scientific’ dials,
which have  a sloping gnomon, which appeared in the 16th century but which only came to some rural areas in the mid 17th century.

The increasing importance of European Mass Dials

The growing interest in mass dials in continental Europe is evidenced by a flow of reports and photographs. BSS of course has quite enough to do without compiling registers of overseas dials but the reports are filed and available for comparison with dial types and locations recorded in Europe.

Here Tony Wood reflects on the similarities and origins of mass dials in the British Isles and Europe.

 Astrolabes, Cross Staffs and Dials. Way back in 1992, Peter Ransom, later to be elected President of the Mathematical Association, published a fascinating article  extolling the use of old scientific instruments when teaching geometry in schools. His article makes wonderful reading and gives the background to (and the use of) the Cross Staff, a Horizontal Sundial and even a quadrant.  Click here for a link to this article.  NB Free  registration to MyJStor allows free on line reading of this article.  A small charge is required to download and keep the whole article.


Mystery of a Missing Dial. Way back in September 1992 super-sleuth John Ingram spotted this unusual and it is believed, unique, dial where steps on a triangular block were used to tell the time.  When he returned in 2004 to York Rd on the South Bank in London to record it for the BSS Register, it was missing! Enquiries of the Council were all to no avail.  Was it stolen or was it lost in the then recent Jubilee Line Tube works? Click on the image for a wider view. The telegraph pole in the middle right of the larger image is said to mark the place where the Festival of Britain Skylon stood in 1951.  Anybody able to tell us more about it, its designer and who made it?  Replies to the Webmaster please.

SunInfo opens a New Page! - listing the HUGE bibliography of BSS President Christopher St JH Daniel MBE.  Listed here are his published articles, the full list of his many contributions to Clocks Magazine and even a summary of the sales of his extraordinarily popular Shire Publications book 'Sundials'.  We are delighted to be able to provide as an academic resource the incredible output of the UK's foremost Diallist.

Have a look at Illustrating Shadows.  The website of Simon Wheaton-Smith is an excellent dialling resource with lots of downloads, presentations, dial designs etc. Most free and all well worth a look.  You can access it here.

The Sundial Removed?  Here Harriet James tells the story of the 'Simmons Bequest' that threw up the idea that the huge dial in All Souls College Oxford might be returned to its earlier place in the College. The early history of the dial is here, Christopher Wren and William Oughtred both make an appearance and all is followed by the final decision by the College. Read the BSS Bulletin article dated 2006 for yourself here [C-466/12].

 Sundials to see. A new venture for SunInfo.  Here is a changing section of dials that are worth visiting.

BSS 2016 Accounts finally available. Owing to what is presumed to have been an administrative problem at the Charity Commission, anyone wishing to see the 2016 accounts for the British Sundial Society had not been able to view them on the Commission's website - only the Trustees' Report was initially available. Both may be now viewed at the link above (courtesy of the CC) or at the Commission's website. The latest accounts show a welcome profit after the earlier years of worrying losses.

The Holes and History of the Beccles Church Dial - an anniversary!
It was ten years ago in 2005 that the mystery of the holes that are pierced in the remains of the vertical dial on Beccles Church in Suffolk was unravelled. The BSS Registrar at that time was Patrick Powers and in an earlier article in the BSS Bulletin he had posed the question. Quick as a flash, two eminent BSS diallists explained it all. A second article in the BSS Bulletin was clearly necessary!  Read that article here to find out the answer and to have a chuckle at Roger Bowling's succinct summing up!


 Smiling Sundials. Pareidolia or what?  Here are two dials that seem to be smiling! They are both in Germany.  The first  is in Dörnthal, Sachsen and pareidoliathe second in Nuremberg.

A NEW Sundial Data Resource has been developed by Kevin Karney. Available here the page provides a wide variety of data for those interested in sundials and solar parameters.  The latest addition is to provide a high precision calculator for the Equation of Time and the sun's position.  However the page also contains links to dial designs of his own and to animations of dial shadows.  Well worth a look!

 Did you know? An astonishing number of pictures of sundials and their pedestals can be found by searching Google®.  Try looking here for one amazing collection. Here you can see both sides of a rare Melvin dial, a few other very old dials, some heliochronometers, modern dials and of course some non-working 'garden centre' dials as well. Well worth a look.

Then and Now... A NEW page has been started here on SunInfo to show some of our sundials as they were long ago and as they are now.  The first entry is the unusual dial at Warwick Castle - a dial which on the face of it looks unfinished to our eyes because it has no numerals.  Yet a 1912 drawing of it shows that it possibly never had!  The second in this series concerns the famous Countess's Pillar, the  third concerns a moved dial in Rye and the fourth the Pilkington & Gibbs dial at Thornton Manor.  Have a look here to see for yourself and keep coming back to see what other dials have been added as we explore more of these interesting sundials of the UK.  Then and Now

Make your own paper sundial. Fabio Savian's collection of 13 amazing designs for paper sundials are now available to all. He has designed several but others like Valentin Hristove and the North American Sundial Society have also contributed designs to this excellent Sundial Atlas project. Just have a look here ! There's even a design for a solar compass.

Or you can go back to this 2004 BBC page for Norfolk Children.  It too tells how to make a paper sundial. It will work for most of England though you will need to correct the reading a little if you want to measure clock time.

Francis Barker's Instructions for Setting a Dial. Francis Barker of Clerkenwell was an important dial maker at the start of the 20th Century.  In 1914 he contributed a chapter about setting up a dial to Geoffrey Henslow's Book:  'Ye Sundial Booke', 1914.  This chapter makes interesting reading.

Edward R Martin's Mass Dial Database was compiled by him over many years using an early computer and specialist software written by his son.  In fact all the data was at one time thought to be lost following a computer failure not long before Edward died. In 2002 the factual detail of the database - though sadly not his novel customised dial diagrams - were eventually recovered for him in 2002 by Patrick Powers but, after his death, amazingly were again mislaid until now. This database of some 1000 mass dials includes some details that are not now recorded even in the BSS Mass Dial Register.  A guide to Edward's novel codes for the locations of the dials on the church is included.
The recovered file (in PDF format) may be viewed
NB An Excel version (3.3MB) may be obtained upon application to the webmaster.

A Day out with Edward Martin and Mass Dials. A rare record of a day which CLIVE FEWINS of the Independent spent  with the late Edward Martin. It was on Saturday 20 July 1996, when they looked at the marvellous mass dials on St Peter's Church in Hanwell near Banbury.  Click HERE to read it.

10 Reasons to revisit a Registered Dial. Many BSS Members send in reports of dials to the Registrar for inclusion in the National Register. Although at first glance it might not seem to be necessary to revisit an already recorded dial, this is not the case since repeated visits over time provide a record of a dial's changing condition and also can provide more information about the dial than might have been noticed earlier.  In October 2007, BSS Member John Ingram sent in his amusing and rather 'tongue in cheek' list of ten reasons for revisiting a dial.  Read them here.

The Official Opening of the Brighton Emmaus Community analemmatic sundial was conducted by Dr. Robert Smith (University of Sussex) on Saturday, June 29th 2013  at the Emmaus Open Day by uncovering the midday-stone at 1 p.m. Sir Patrick Moore recorded the following instruction last September to be played at the opening ceremony. “Congratulations, Here we go! Uncover the Midday Stone.” See more here

'Induce Animum Sapientem' There is an interesting sundial web site which is operated by dial makers Peter and Yvonne Daykin.  It is devoted to the sundials of  Derbyshire and is well worth a look.  Their Home Page is here.  More than twenty five dials are shown, some modern and some old.  The famous Eyam dial is there too!

The Sundial at All Saints' Church in Isleworth has now been restored.  Installation took place during Saturday 25th May 2013 and the sun actually shone for the occasion! A picture* of it complete, but just before installation is here.  As well as the ordinary problems associated with any dial restoration this one had a few more!  Some initial information can be seen here.  and for BSS Members an article about the restoration is in the June 2014 edition of the BSS Bulletin.  Alternatively, a copy of the same article may be read by everyone here.

*Perspective slightly adjusted in view of the difficulty of photographing such a large object indoors!

Medway Council eliminates one of the Nation's most important sundials! In an extraordinary move, Medway Council in Kent has chosen to take down one of the most famous sundials in the country, SRN2936 in the National Register, which was in Railway Street, Chatham and which commemorates both the day and the time of the death of Admiral Lord Nelson. The dial was designed over twenty years ago by Christopher Daniel MBE, the President of the British Sundial Society, and it has been a major feature of the town since then. It is a dial known to thousands both in the UK and overseas.

The worrying thing is that there is currently a suggestion of it being placed in a museum - all rather suggesting that the problem of reinstallation had never been considered let alone planned.  More can be found about this in the article in the 9th March edition of Kent on Line Click here to read more. 


Then Click here to read Chris Daniel's 1995 article about the original installation and how Chatham regarded it then!   Hint: In 1995 it was then regarded as the  'Jewel in the Crown' of a £5.5M investment to improve the environment of Chatham! How the Council's knowledge of the town has changed.   


NOW!! see the further Kent on Line article about this - here and go here to read NASS's comment of 14th April on this worrying development.  BSS also became involved in this on 15.03.17 and they too have written to the Council.  Let us hope that Medway Council reconsider.


Now the local MP (Tracey Crouch) is involved and the Nelson Society has been informed.


If you wish to register your concern about  this most unwelcome development the contact is Alan Jarrett, Leader of Medway Council, Gun Wharf, Dock Road, Chatham, Kent, ME4 4TR.

Just imagine! Places where sundials work in the summer but not in the winter - even when they might be bathed in sunshine throughout the year? You might think this cannot be but in Viganella in Italy and now in Rjukan in Norway that is so.  How so?  Read here.

A look at the Savoy Centenary Sundial The Savoy Hotel was founded in 1889 and 100 years later in 1989, Christopher Daniel was commissioned to design a dial to celebrate that event and of course to mark its  foundation by  Richard D'Oyly Carte.  Look at some of the images of how it is today and read the extensive description at its base.

The dial is 610 mm in diameter and takes the form of a four ring type armillary sphere.  See more of this dial today here


The National Trust and the 'Housewife's Trick'?

The garden at the wonderful Wisbech property, 'Peckover House' is especially lovely at this time of year. Not only that but there is a sundial just outside the greenhouse which greatly enhances that part of the garden.  Odd therefore that when these images were taken - it was at 09:21 GMT in March - the dial was showing just over 10:30!

Surely the NT has not succumbed to AP Herbert's rather unfairly named 'Housewife's Trick' whereby a sundial is turned so as to indicate summer time?  Given its age and the extent of corrosion present it's hard to read this dial exactly and thereby to work out just how much the dial has been turned but, despite every diallist's 'horror' at such a practice, it has to be said that in summer, in the middle part of the day and at the latitude of the UK it is not quite so inaccurate as one might think. At least it might help to prevent the frequent comment made by members of the public when checking a sundial with a watch, of 'It's wrong'. So maybe the misjudged housewife has done us a service after all?


WD& HO Wills Cigarette Cards Several decades ago the cigarette companies Wimborne Minster cardwould insert give-away cards in their packs of cigarettes to encourage sales. These were issued on all sorts of topics in the hope that customers would collect them and so keep buying their packs.  The practice didn't last but even in the 1950's Wills kept the machinery maintained in case a 'cigarette card war' started again.  Here we have a link to the cards that they printed on Sundials - with that for Wimborne Minster shown in the thumbnail. Click that image to be able to see the obverse and reverse of these cards. There is a short decription of each dial on the reverse of each card.

The Rousham Sundial again! We last visited this dial in 2018 but it is always worth another visit.  This time with some close ups of the dialplate and with the information (from the owner no less) that it is currently quite badly misaligned after some boisterous children had knocked it over a few years ago and, in the process of properly securing it, it has simply been fixed upright again. We have been told it will be looked at when time permits.

Click on the image
for more information about this lovely dial by Dolland which despite a little wear can still be read in all respects.  Its many scales make this a true scientific instrument set in the lovely gardens of Rousham - particularly with its marvellous dahlia display this autumn.

The Dial at Fountains Hall Fountains Hall is a Grade 1 listed country house in Fountains HallRichmond (N Yorks) which has a sundial over the front entrance. Amazingly the dial is not mentioned in the listing and this might account for its current state. It is a Direct South Dial the gnomon of which is currently slightly twisted. The lower part of the carved sandstone dialplate is also badly weathered.  Nonetheless it is all still largely visible and it is well worth a look if you happen to be in the area.

The History of the Countess's Pillar Here's an interesting article about the Countess's Pillarhistory of the Countess's Pillar, one of the more famous dials in Britain which was restored recently by Christopher Daniel. The dials and the pillar were placed there by Lady Anne Clifford, the last of all the Cliffords, who by her force of character and charitable works left her mark on her property and a legend in the county of Westmorland that remain to this day. The link here is to chapter four of "A Tour In Westmorland by Sir Clement Jones, published 1948".  It makes interesting reading.  Her charitable gift is still in existence and is managed as a named charity by the local council!

The Sundials of New College, Oxford Twenty Years ago, the UK's famous dial New Collegemaker, Harriet James, publlshed an interesting article about the history of dialling at New College Oxford.  She then magnificently ended her article with a description of her own addition to the College on the Muniment Tower.

This turned out to be a bit of a saga which Harriet bravely reported for the benefit of all diallists and she acknowledged the help and advice of others in getting this quite magnificent dial installed.  Those of us who have our own experience of the design and installation of large dials know only too well just what problems can arise.  Her end result of a 20 second accuracy is remarkable and her account of this in her article linked below is well worth reading or even re-reading!.

The Dennis Cowan Sundial Trails Over the years Sundiallist Dennis Cowan Lectern Dialhas put together a number of quite fascinating sundial trails of Scottish dials.  Readers will know that Scottish dials frequently have a style all of their own but despite their relative rarity there are many such that are well worth looking at. Despite this they are not shown as much as you might imagine. So, over the next weeks and with Dennis's gracious permission, SunInfo intends to feature a few of these trails. 

Our first trail encompasses the dials of the Royal Mile in Edinburgh including those to be seen there in the National Museum of Scotland. The image here shows a lectern sundial, dated 1781, from Cantray in Aberdeenshire, with the monogram DD (David Duncan) and with dials for 13 locations around the world. These are Cantray, Peking, Goa, Rome, Jerusalem, Cairo, Naples, Syracuse, Ozaca, Troy, Smyrna, Bengal and Paris. This sundial was gifted to the museum around 1931 by Miss EM Davidson. It is of grey sandstone. Just compare the complexity of this Scottish dial of 1781 with the English dial in Alnwick of the not dissimilar date of 1737 which is shown lower down on this page. Click on the thumbnail to see a larger image. The full trail can be downloaded as a PDF

Twenty years on! To mark the Millennium Amble Council in Amble Sundial in 2020Northumberland commissioned a firm of architects in Newcastle to turn their asphalted car park into a civic amenity. A part of this was to be a large central sundial and Patrick Powers was commissioned to design it. During a recent visit to Northumberland a visit was made to see how the dial has fared after nearly twenty years! It turns out to be in remarkably good shape. Clearly the area is being very well maintained and is well worth visiting if you are in the area. The dial was set out on a N-S line which was also used to locate a small amphitheatre and on this visit it was pleasing to see locals seated in that to chat as well as others, including children playing, in the square. The redevopment won the 2002 RTPI Award too. Click here or the image for four images of the dial today and click Here to see more about the dial's development and installation and even about its accuracy - at least at one part of the time scale! - when it was completed.

Revisiting an old friend.. In a recent visit back to Northumberland it was Alnwick's High Street sundialpleasing to see again the old vertcal dial on the side of Willcox's Jewellers in Alnwick's main street. 

Constructed in 1737 and bearing the initials I.F. it is a Direct South dial in slate, still in remarkably good condition and showing in Roman numerals the expected 6am to 6pm in quarter hours with half hours marked by fleurs de lys.

The Summer Solstice and a Dihelion Sundial The Edinburgh sundial company Dihelion sundialMacmillan Hunter's latest newsletter reports that (surprisingly perhaps?) the summer solstice 2020 in Edinburgh was a day of beautiful sunshine. It really showed off their Dihelion dual sundial which can read the solstice and the equinox seasons as well as the usual daytime hours.

The time shown here is before 8 in the morning solar time, or nearly 9 am in British Summer Time. It is still well before noon, when the horizontal rod is able to mark the passage of the four seasons by its shadow. Read more of this HERE

David Young and Gordon Taylor SunInfo is sad to report the recent deaths of two important British diallists. 

David Young
who was a founder member of the British Sundial Society and during the early days with what might be described as an 'all hands to the pumps' regime,  it was he who took on multiple roles at the same time being the first Secretary and the Society's first Registrar.  He and his wife Lilli took amazing care of the fledgling society alongside Christopher Daniel at that time to the point that he would take time to visit and effectively interview potential members of the Committee that may have been proposed and had agreed to serve. David was a prolific reporter of sundials for the newly established Register, vying alternately (it then seemed) with Tony Wood as the two BSS Members who had arguably discovered the most dials in the UK.  Always friendly towards new members he was supportive of any new ideas by which the society could be improved and so, perhaps unsurprisingly, he became highly critical after a new Committee took over following Christopher's retirement as Chairman, when he perceived a succession of mistakes in charity management.  In later life David moved more towards his other passion, that of the history of his local area. David will be much missed by all his friends in British dialling.

Gordon Taylor was another early committee member of the Society who provided much expertise and academic flair which materially helped the acceptance of a new professional Society and moreover one which was seeking to change the then habit of the National Trust in using dials as ornaments that could be moved from garden to garden. Thankfully and to the credit of the Trust, that was quickly corrected and today both the Trust and English Heritage are  most vigilant in that regard.  Gordon will be particularly remembered by BSS Members for his design of the first public Equiangular Dial in the UK and for his 1975 book on the topic.  Designated SRN 1773 the dial was designed for the Royal Greenwich Observatory then located at Herstmonceaux Castle. After a temporary move to Cambridge the dial is now back there at the castle once again, as a fitting memorial to a memorable diallist.  See more here

The Sad Dial at the Lygon Arms Hotel. The Lygon Arms Hotel in the Cotswolds Lygon Arms Hoteldistrict of the UK lies in the High Street,of Broadway, Worcestershire.  It is an old and established high quality hotel build from the local Sandstone.  This explains why the often missed sundial on the right hand front facade is no longer operational.  It does however still retain its unusual gnomon which is somewhat more ornate than those usually seen.  The dial must have been a Vertical South dial but sadly few if any markings remain.  This must surely be one case where re-engraving would be worthwile and not a violation of 'conservation' principles. Click on the image for a fuller picture - Can you see the dial?  See a closer image here and an even closer image here

The Dial in Italy's Sigurtà Garden Park. Magda and Joseph Sigurtà have tirelessly maintained the garden that was first restored by the pharmaceutical industrialist, Dr. Giuseppe Carlo Sigurtà from the 1940s.

In 1990 a sundial was constructed there and surrounded by water. Click on the image or HERE to see larger images of this interesting sundial, seen here at close to the 2019 autumnal equinox.


April's News from Border Sundials The latest addition to 'News from Border Sundials' can be read here. This edition mentions the Sundial on Wilton Bridge, Ross-on-Wye, Herefordshire. Read about its history, why it was moved and read its depressing motto: "Esteem thy precious time; Which pass so swiftly away; Prepare thee for eternity; And do not make delay". The sundial was commissioned by Jonathon Barrow - originally from Monmouth but who lived in Bridstow just outside of Ross-on-Wye.

The Sundials of the Castle and Collegiate Church of St. Michael of the city of Pforzheim, Germany are shown here. Sadly few documents exist today concerning the origin and history of either the clocks or the dials of the castle church. Nonetheless, it is known that until the 19th century the mechanical tower clocks had to be readjusted daily or weekly with the help of sundials, which were mostly nearby and in some cases even only as noon dials.
The existence of the sundials at the castle church can today only be deduced from the beginning of the 19th century. The recently restored sundials shown here make use of the southwest corner of the church, because that area is illuminated by the sun all day long. They are relatively large and ideally located to make the time fully visible and they have been mounted high to discourage vandalism. Unfortunately, it is not clear from existing illustrations just how the original dials were executed. Even investigations during the restoration of 2014/15 gave no indication. Only the attachment points of the original gnomons could be seen.  The dials here have been wonderfully executed by Siegfried Netzband, (delineation) and Schorn, Marxzell (painting). Click on the image above to see both dials set around the corner of the church.

An interesting new, painted Italian dial of classic design.
Here is a painted dial on a house on the Eastern side of Lake Garda in Italy.  On one of the houses overlooking the Lake and accessible only along the very narrow roads of that area.

Constructed (or perhaps repainted) in 2009 it bears the motto
"Di ferro e' lo stil, d'oro il tempo". (Iron is the style, gold the time). It displays local solar time from 9am to 8pm.

Dials of Polesden Lacey Polesden Lacey is an Edwardian house and estate, located on the North Downs at Great Bookham, near Dorking, Surrey. Built by Thomas Cubitt Ambrose Poynter it is a designated World Heritage site.  It has several dials the main one was stolen some years ago and a rather poor replacement has been put in its place on the original elegant cherubic pedestal. 

See the dials here: Dial 1, Dial 2, Dial 3a, Dial 3b

The Kiftsgate Sundial Kiftsgate Court Gardens is situated above the village of Mickleton in the county of Gloucestershire, England, in the far north of the county close to the county border with both Worcestershire and Warwickshire. The gardens, famed for its roses, are the creation of three generations of women gardeners.  This wonderful pedestal supports a perhaps less wonderful dial but is nevertheless worthy of note.

There are more images of the dial's details Here, Here and Here

 The Vaux-Le-Vicomte Surprise...! A visit to the Chateau de Vaux-Le-Vicomte  in Maincy, near Melun, 55 km SE of Paris in the Seine-et-Marne département of France is always a delight. However when visiting the Grand Salon there you are in for a surprise because the tiled floor of the Salon is set out as a dial without an obvious aperture gnomon. Sadly nothing available to read about the salon mentions this nor does the plan being carried out for restoration.  Can diallists in the area please let SunInfo know the history of the dial or meridian line and whether it will be restored to its former glory?  Click on the image for more detail and see more of the floor markings of the Salon Here, Here and Here

 The Chantilly ‘Dôme’ Sundial is certainly rarely seen!  It is at the Chantilly Gardens North of Paris - inside the outdoor manège there,  an extraordinarily interesting part of the stables few otherwise get to see - unless there to witness an equestrian demonstration of course. The key equestrian shows and demonstrations take place beneath the 28 metre high majestic dome of the Great Stables, with its ring and its spectators' stands that can accommodate 600 people. Its recently restored fountain features the dates of construction of the Great Stables (1719-1735). The almost invisible sundial in the outside manège faces due South but has an horizontal gnomon. It is dated 1737. Click on the image to see a better version with more detail.  A nice dial.

Is this Dial still showing the time? The Colorado Transcript Newspaper dated 21st January 1909 had a small column remarking that sundials were still in common use in Mexico.

The article showed a line drawing of one such high on a building but sadly its location was not identified so we are at a loss to know if the dial still exists.  Can any reader throw light on the location of this dial  and say if it might still be in existence?

The newspaper entry may be read here. It makes interesting reading.

A Real Victory for Science After an academic career of more than 30 years, Peter Ridd had his employment terminated as a professor of physics at James Cook University in Townsville, Australia.  Peter had spoken out against the accepted orthodoxy that climate change was ‘killing’ the Great Barrier Reef. He was able to crowd fund his chance to prosecute the University by raising $AUS 250,000 in five days!  Peter writes: "My lawyers have told me that the judge handed down his decision and we seem to have won on all counts".
Peter’s court case has enormous implications for the international debate about climate change, and for the ongoing crisis surrounding freedom of speech in academia.

Reinhold Kriegler SunInfo is very sad to report that the sundial enthusiast Reinhold Kriegler died on Saturday 23th March 2019 in Dessau. Over his lifetime he made many contributions to the field of gnomonics. For those who remember his extraordinary web site it still available to view and is at or more specifically for his dialling work at
In there he describes his on going interest in the Reinhold crater on the moon - not of course named after him but still precious to him nonetheless! Just one of the many comments says it all: "Kriegler exemplified the best of what a community of dialists would be like. The most civil, civilized, inoffensive, polite, considerate, member. Those attributes stand out, aside from his impressive website with its wide coverage of dials and dialists worldwide, and his own artistically-aesthetic dials". RIP.

Using two Sundials to destroy the idea of a flat earth!! Here's an ingenious YouTube clip that shows a way of using two sundials and a lamp to prove the earth cannot be flat. Additionally it includes a link to a place where you can print off a foldable paper sundial for any place on earth. How about that?

 St Martin's Cathedral, Leicester has an interesting declining dial on its otherwise South wall somewhat  to the right of the porch. The Cathedral is not built to the conventional E-W axis and the dial in fact declines approximately 15 degrees East.  Designated in the BSS Register as SRN 0854, it is some 600mm square. Its Motto reads: "Coeli Enarrant Gloriam Dei". The dial displats solar time from 5am to 3pm in hours. Curiously no half hour markers or actual hour lines are drawn. The dial's design encompasses four squares around a small centre boss each with carvings clockwise from the upper left: angel, bird, winged ox, winged lion. There are some traces of gold infill.

The Delightful Dial of Dalemain in Cumbria The well known octagonal dial at Dalemain Country House by Richard Whitehead is dated 1688 and shows the time from 4am to 8pm in half, quarter and eighth hours on scales that lie inside the chapter ring and in minutes (with Arabic Nos) on the outer edge. Some of the actual hour lines on these inner scales are missing [eg 6 and 7pm]. There are both inward (arrow with H form) and outward (line and dot form) half hour markers. An elaborate inner 32 point compass with all points named [eg SEbE] and on an adjacent (outer) scale with its reciprocal [eg NWbW] so as to give the sun's bearing. the compass was designed to be used with vertical rod (not present) which was passed through holes in the gnomon. and centred on the compass. Markers on either side of the main 32 points indicate the width of this shadow for accurate centring. Two scales further divide each of the 32 points into 4 and 8 intervals. A half division is provided outside these scales (to the inside of the dial) and marked by an inward line with a three dot arrowhead. Wonderful pierced gnomon with scroll pattern, the whole mounted on an excellent panelled octagonal stone pedestal which is slightly fluted and with no visible base. Design Lat N 54d 40m.  More detailed pictures HERE dated May 2009.

 The Famous Blackamoor Dial of Dunham Massey. This important National Trust dial dates from 1721, is 450mm in diameter and is listed by Heritage England as "Early C18 and is thought to be either by Van Nost or by Carpentiere".

Stone with a bronze dial. 2-step stone base with nosings on which is a kneeling African figure clad in leaves carrying the sundial above his head. Nat Grid Ref: SJ7350787376. Thought to be one of  five such original figures only three of which are known today.

Click on the image here to see a few close-ups of this now (sadly) very corroded dial which nonetheless can still (just!) be used to tell the approximate solar time.

The Two Tatton Twins . Yes, we know that the word 'twins' implies 'two' but we just like a bit more alliteration!  Whatever, there are no fewer than two horizontal dials at Tatton Park in Cheshire.  Not discovered for a long time  - and one of them not apparently even yet recorded in the NT collections of such either - these sit there waiting to be admired. One is in the Rose garden (sometimes only on view from a distance because of the roses) and one is near the Italianate garden at the back of the house.  They are well worth a look. Click on the thumbnail images here for larger views and for a couple of close ups of the second dial.  Two interesting dials.

New H.E. record for a pedestal at Wardley Hall. Here's a Valentine's Day present for those interested in dial pedestals! An Historic England list entry discovered by SunInfo on 14-Feb-2019 describes a pedestal (sundial shaft), now forming the base of a table. C18. Stone. Bulbous stone baluster with moulded head and base. The dial has been replaced by a stone table top probably during the C19. Listing:  NGR: SD 75787 02185.
Not often a pedestal gets listed without the dial! Can anyone send in a picture of the pedestal that we can publish?  Click on the picture for Google's locational image.

Bridge End in the Snow!  The dial that is located in  Francis Gibson's Garden at Bridge End, Saffron Walden is unusual in that it is rarely seen by dial enthusiasts. This is odd since the gardens are very well worth a visit and indeed are listed Grade II* in the UK Register of Parks and Gardens.


Gibson lived 1805–58 and he constructed a long view from the Pavilion along the Pavilion path to steps and two vases, then to the sundial, seat and balusters.  The tapered pedestal is elegantly decorated but sadly  today's dial is without its gnomon. The dial plate is however competently laid out with an eight point compass, sun motif and complete with the slightly depressing motto 'Night Cometh'.

The pedestal my be viewed in more detail here and the dial plate itself here.

Further Dial Development Planned at Luton Hoo The ever popular 2013 analemmatic sundial at the Luton Hoo walled garden is to be partially relaid and better marked out during the off season of 2018/19 so as to be ready for the good weather next year.


It will be recalled that In 2013 the octagonal Luton Hoo Walled Garden celebrated the tercentenary of its builder -  the 3rd Earl of Bute.  An eminent scientist of his day (though  a particularly unpopular Prime Minister!), it was he who, in the 18thC, had been instrumental in the establishment of Kew Gardens. As a part of the celebrations for this tercentenary celebration, an analemmatic dial was commissioned and largely constructed by the Garden's own team of volunteers.


However, what had basically been a straightforward dial delineation task ended up uncovering an extraordinary fact. The garden is nearly aligned to the sunrises and sunsets at the solstices and equinoxes of its location - and it is not clear why!


Read about the Earl of Bute and how, with 'Capability' Lancelot Brown, he moved his original walled garden from near the river up no less than 200 feet to the top of a hill, arguably to the most inconvenient location on the estate for a huge five acre garden and one that requires similarly huge amounts of water.


Bute combined his interests of botany, astronomy and philosophical instruments all of which appear to be significant in the concepts behind the walled garden. Why was it built like this?  It looks like it was the appeal of exotic soft fruits!

The San Marco Noon Mark - Venice. In our Dial Time Newsletter for April 2016 we published a note about the rarely noticed Noon Mark that exists in St Mark's Square in Venice.  It is damaged, rusted, drooping and possibly even now loose as well yet it still shows solar noon to within 13 mins and that after something like 630 years!

Seen again in November 2018 - in this picture taken at a solar time of approx 11:51 am - though the shadow has just passed the noon line. Click on the thumbnail here for a larger image.

A Sundial Tartan - how about that? Recently the 1890 Kinloch Anderson Sundial Monument in Inverleith Park, Edinburgh was restored by Macmillan Hunter Sundials. As a part of the 150th Anniversary Celebrations in June this year, a unique Commemorative Tartan Cloth - The Sundial Tartan - was produced. Stationery publishers Waverley Books were asked by Kinloch Anderson to produce notebooks in the style of their Tartan Cloth Commonplace Notebooks using the same Sundial Tartan.
These Sundial Notebooks are now available, as an exclusive limited edition, to collectors and friends, from Kinloch Anderson. The background to the creation of The Sundial Tartan is a fascinating story which is told in a booklet enclosed with the notebook.

When you are next in Dún Laoghaire, do take a stroll out to the East Pier and there you will find an interesting analemmatic sundial. In an article in the Irish Times some years back there was a mention by Peter Lynch, Professor of Meteorology at the School of Mathematical Sciences University College Dublin.  In it he describes the dial which had been delineated by Irish dialling enthusiast Captain Owen Deignan in 2006. Read the Irish Times article here.  Sadly the article does not show an image of the dial so we are here much indebted to Michael J Harley who has developed his own extensive register of Irish sundials and which is well worth a look and well worth bookmarking too.  Go here to see the Dún Laoghaire dial in more detail and Go here to visit Michael Harley's Register of Irish sundials. We'll be back soon with a few more Irish dials all courtesy of Michael Harley's Register,

 RA (Nick) Nicholls  SunInfo SunInfo is sad to have to report that former Trustee and meticulous Treasurer of the British Sundial Society, Nick Nicholls died on the 2nd October 2018. He was aged 92. Nick was a Civil Engineer by training who brought the welcome discipline of an engineer to the management of the young and developing Society. He was BSS Member No.47 and he joined the other founding members as the first formally defined Treasurer. He also contributed much in the founding years when the Society struggled to advertise itself and somehow managed to fund and publish the first Bulletins. These were the years before the internet when information about basic dialling was very scarce. The early Bulletins were vital to recruit solitary diallists from their isolation and those who wanted to learn more about sundials. A lovely man with an equally lovely, dry sense of humour, Nick will indeed be sorely missed. A fuller obituary is here

An Aberdonian Triad!  Three lovely sundials from the Aberdeen region are here described by Denis Cowan in a paper submitted to the BSS Bulletin in early 2018 and available to read on his website.


The dials are respectively in Ellon Castle Gardens, about seventeen miles to the north of Aberdeen, in Pitmedden Garden, just a few miles to the west of Ellon, and the third is in Duthie Park in Aberdeen itself.  Read Denis's article here

The Good News and Bad News about a Dial. The discovery of a rarely seen great declining dial is rightly good news, as is the fact that clearly the dial in question has recently been carefully repainted. So, what then might be the bad news in the heading to this entry?

This dial has only recently been recorded. It is in Amptill in Bedfordshire, UK and the facts about it were the subject of an article in SunInfo's Dial Time 2018. Read about its problems here

The Sundials of Wisley The Royal Horticultural Gardens at Wisley contain two sundials.

The first is located at the entrance to the gardens - almost as you come in - and the second is in the Herb Garden. Both are now modern dials though one replaces an earlier horizontal dial by Barker.

The gardens make a lovely day out and the two dials are interesting too. Click Here or on the image for more information and some images of the dials. Then admire 2018's dahlias!

The History of UK Summertime/DST
In 2016 the BBC broadcast a programme describing how Britain introduced Summertime (daylight saving time) 100+ years ago – a move that was quickly followed by countries worldwide.

A quarter of the world now use DST. Like it or not, there’s a persistent British campaigner you can thank.. He came to be supported by Winston Churchill and Sir Arthur Conan Doyle too.

The Dial at Boughton House In the lovely rose garden of Boughton House can be seen the Henry Wynne sundial. Displaying a 32pt compass, the times of noon at twelve cities and all set in a 'secured' dial plate of some 425mm diam which is mounted on an octagonal plinth. The cities are marked as Mexico, Charlestown, New York, Barbados, Tenerife, Dublin, Paris, Rome, Jerusalem, Babylon, Surrat and Bantom. The dial shows 4am to 8pm with its numerals read from 'inside' the dial.

The Hugget Heliochronometers Brian Huggett and his wife enjoy visiting gardens, in part to gain inspiration for their own. Such outings in the summer of 2016 led him to consider installing a sundial in their garden. Knowing little about sundials, he inspected those they encountered and was dismayed to discover that none agreed with his watch. Even those that claimed to reflect clock time required additional consultation of a table or graph. ‘What we need,’ he said to his wife, ‘is a sundial from which clock time can easily be read by anyone.’
‘Why don’t you make one?’ she replied. See the consequences of this suggestion here in two excellent articles. Heliochronometer I, Heliochronometer 2


 Charles Darwin's Sundial at Down House is still to be seen at the head of the garden.


It is to be found near the verandah although currently and sadly, it is not quite correctly set up.  It is a commendably simple but accurately delineated, dial set on a lovely baluster pedestal - clearly positioned for use in earlier times to set the house clocks.


It displays the hours 4am to 8pm in 30, 15, 10, 5 and 1 min divisions.

 Prof IDP Wootton  SunInfo is sad to report the death on 16th July 2018 of Prof Ian Wootton at the age of 97. Outside his distinguished  clinical role, Ian was a founder Trustee and Council Member of The British Sundial Society.  In earlier times he was appointed to the position of Registrar of  the Society after David Young had relinquished the role which he had held since  the startup of the Society.  Ian also  initiated the very first Society-operated webpage, identifying and then implementing the Society's web addresses and acting as webmaster. Read SunInfo's Obituary to Ian Wootton.   Ian will be sorely missed by all those who knew him and who are pleased and privileged to have worked with him. A real gentleman.

 A chance to read about Seasonal Markers for Analemmatic Sundials. In 2006 Roger Bailey published his article on Seasonal Markers for Analemmatic Sundials. Written to answer questions such as “Can a sundial be used to follow the sun through the seasons?” or
"Is there a point in an analemmatic sundial that can be used with the Zodiac date line to show where the sun rises?”.  The answer is of course Yes!

 A chance to see a real Merkhet The Merkhet (or merjet "instrument of knowing") was an ancient Egyptian timekeeping instrument. It involved the use of a bar with a plumb line and could be used during both morning and afternoon hours.  A short video clip shows one such in a museum Here Two of these instruments could also be used, together, to determine North. The merkhet consisted of a string with a weight attached to one end, enabling a straight line to be measured. For the operation to work, two merkhets were required, one aligned with Polaris, the North Pole star. If erected properly, and if a merkhet  was on hand, one could estimate quite accurately the time by observing the transits of certain stars as they crossed the meridian and came into alignment with the two merkhets.

 Previously unknown UK sundial location revealed! The National Trust property of Clumber Park in Nottinghamshire is suffering from the drought. The building that once stood on here was Clumber House - a grand 18th-Century mansion which was demolished in 1938 after a series of fires and the then economic downturn.

In the present drought, rooms and corridors of the old house have become visible as stone foundations left in the ground heated up more quickly than surrounding material, scorching the soil above to a lighter shade.

Although the location of the lost mansion is well known, amazingly the location of a previously unknown sundial in front of the lawn has been identified -

A Sundial Missing in Zimbabwe... Imagine, if you will, the interest to a sundial enthusiast when this was spotted in the formal gardens of an hotel near the Victoria Falls in Zimbabwe. Then imagine discovering that the company who made it is still in existence in London yet they have no records of it.  A real mystery.

Read a bit more about this intriguing puzzle here.  Do let the webmaster know if you have any information about what must have been a very well made equinoctial English sundial.

The Clifford A. Phaneuf Environmental Center in Springfield's Forest Park, Mass, USA  dedicated a new sundial built by artist James Kitchen and commissioned by the Edward Peck family in memory of Ruth Mahoney Peck who shared a great love for the park.  The dial is fabricated in steel using a skate blade as the gnomon and a saw blade as a base. It was declared 'open' on June 21 2018.

 Barnwell sundial 'stands the test of time'.  On a bright, sunny day outside the Barnwell County Courthouse (that's in South Carolina, USA) there's no need to check your watch to know what time it is.  It is said possibly to be the only 'free-standing' vertical sundial left standing in the USA - can this really be?  Installed in 1858 after it was given to the county by State Senator Joseph D. Allen it has recently been restored. 

It includes an EoT correction table and is additionally unusual to British eyes in having Arabic numerals viewed from the inside of a vertical dial.

The amazing Coade Stone Dial Discovery - AND we made it!! Recently Weston Park’s Head Gardener made a remarkable discovery. Whilst sorting out an area used for their equipment, amongst the detritus of old urns and shoulder high nettles, they found this sundial base. It is no ordinary plinth, though, being a rare Coade stone piece which was last seen at Weston in the early twentieth century when it appeared in a photograph of Margaret Countess of Bradford and her children.  Coade stone is not a real stone but is an eighteenth century man-made ceramic. It was perfected by Mrs Eleanor Coade, in the 1770s and was notable for being twice fired.  Examples exist in a few places in London but only one other at Weston Park.  Only in recent years has this ceramic formulation been rediscovered and restoration made possible.  Look at the pedestal and listen to why it is important HERE.

To restore the plinth and to make a dial for it will cost £20,000 - an amount close to 10% of the total park maintenance available to the charity that runs Weston Park, so a crowd funding approach was started and we at SunInfo asked if you who read SunInfo could help too.

Appropriately and on the very day of the summer solstice it was announced that the project has been funded!!

Britain's beautiful secret sundials An article by Sophie Campbell in the Daily Telegraph in January 2018 drew attention to the many 'secret' sundials that exist in Britain.


She wrote: "They are simple, yet complex, a marriage of form and function, often beautiful, frequently unusable (no sun) and they require for their creation a particular combination of skills: mathematics and artistry."

Then read another article Here, this time from the Financial Times - this time all about the sundial designer putting a modern twist on ancient technology and the dials of David Harber.

 A Very Wet Sundial at Hatfield House! The sundial at Hatfield House in Hertfordshire UK was installed in June 2011 in the garden near the Old Palace. It was designed by William Andrewes of Concord, Massachusetts, USA and is shown here on a very wet Spring day!


In many ways a conventional sundial but there is a twist!  The dialplate is made up of a gnomonic map with the location of the dial at its centre.

Explanatory plaques are arranged around the supporting pedestal and a selection of images of these and of the dial itself
can be seen, though sadly not made very easy to read because of the weather at the time.  More

Summer Solstice at the Duomo  The other day Jim Tallman alerted the sundial community to the 'event' that occurs at (and near) the summer solstice in Florence's Duomo in Italy.  There is an aperture high up in the dome of the Cathedral which, around the summer solstice lets a spot of light fall to the floor and pass over a meridian line that was installed in 1756 - though the aperture might have been installed as early as 1475!.  It was designed partly so that "the measure of the year and the date of Easter be more accurately determined", according to the inscription still visible on the wall near the choir.  If you cannot be there, look at this video of an earlier 'transit'. Thanks Jim for alerting us all to this excellent spectacle.


The Dial at Mackerye End is rarely seen since it is a painted stone declining vertical Click for larger imageClick for larger imageClick for larger imagedial dating back to the 18/19thC and mounted on an end wall of the manor house, deep inside its own grounds. In truth it is not a particularly unusual dial though it does indicate time intervals down to 5 minutes and is well constructed.  The images here also show a pre-WW2 drawing of the house - with dial in place and an approximate calculation of the dialplate using the declination of S13W established here by using Google Earth and the alignment of the roof line of that wing of the house. It shows a close correlation though interestingly, it is slightly different to the original - probably indicating that the actual wall on which the dial is mounted is not quite in line with the roof and in turn, there is a small difference in estimated declination!  Such are the vicissitudes of 18thC architecture...

Astonishing Neolithic Clay Disc from E Jutland appears to record 2 stages of a full solar eclipse on 5 May 2789 BC. Dr Oosthuizen (Reader in Medieval Archaeology, University of Cambridge) suggests the sun is the larger circle, its rays radiating out like a child's drawing; the moon approaches it from bottom right, & then moves in front of the sun - all as per the diagram....  Click on the images for slightly larger view.


But, might this be akin to one of the Los Millares multi-sun artefacts known from Andalucía, Spain, which appear to be connected with the visibility of the constellation Orion and the time of deer rutting? What do you think?


A Roman Sundial dating to the 1st century B.C. has been  found in Interamna Lirenas, Italy. It was commissioned by a man named Marcus Novius Tubula to celebrate his election to the office of tribune of the plebs.


He had his name inscribed on the base of the sundial, and paid for the whole thing “De Sua PECUNIA,” or with his own money.


The dial is in astonishing condition and is complete with its inscription - a rare find indeed.

'Unrecorded' dial discovered on the BSS Conference coach tour.


This year's BSS conference reinstated the earlier practice of a coach tour of dials and by all accounts it proved a success, not least because a dial was spotted by one of the delegates which seems to be unknown as far as the UK National Register is concerned! The dial is located high on St George's Theatre in King Street, Great Yarmouth.  It is a West declining dial painted in bright colours.  Click on the image here for a closer look.

The Craigdarroch Dial - found under a bush!

A dial dated 1777 has been found hidden under bushes in an overgrown garden in a small village near Inverness. Known as the Craigdarroch stone after the place where it was found, it was recently restored by Macmillan Hunter Sundials of Edinburgh. It carries the remarkable motto “Each one that reads remember ye the time that is no more shall be.”

The Sundial, Lichfield Cathedral, Staffordshire. This sundial, previously located near the South door of the Cathedral was removed in 1781 and re-erected in 1785 at the West end to regulate the clock on the tower.


It was removed again in 1881 and passed into private hands but it was returned to the cathedral in 1929 and put on a pedestal in its present position south of the nave.


It takes the form of a cube dial with gnomons and time scales on each face.

Howard House sundial restored at last.  One of Norwich’s most significant historic houses has been restored at last. The Grade II* listed Howard House had stood empty for more than 25 years and it had even been designated as at risk owing to its deteriorating condition. But after the restoration, its roof and external facades have now been carefully repaired and restored.
Howard House, on King Street, dates from the late 16th century and originally was owned by Henry Howard, Duke of Norfolk. The picture shows the West declining 1840s sundial as it is now following the restoration. Click on the image for a larger version..

Hitchin's Physic Garden Sundial This month's dial is the most unusual one that is in Hitchin's so-called Physic Garden.  The garden commemorates the first commercial production of herbs in 1846 by William Ransom, a member of a prominent local Quaker family.  It opened on 20th May 1990 in the grounds of Hitchin library and museum in Paynes Park. It is divided into four sections: Household; the William Ransom border; External Ailments; Internal Ailments. It contains a most unusual 1990 sundial in the form or a mortar and pestle dedicated to a late president of the Trust. The motto reads  "Disease doth oft rise above medicine". Click the image for a larger version. The dial was made by Joanna Migdal.

There is a wonderful dial in the gardens of the moated manor house 'Menkema Manor', in Uithuizen, Holland 53.4°N, 6.7°E.  Information sent to the Sundial Mail List courtesy of Frans Maes tells us that it is an elaborate multiple dial, dating from 1722.  The base is formed from two stacked cubes, one rotated by 45° compared to the other.  Each side of the cubes has a vertical dial, though the gnomon of one has been wrongly aligned..

The gilded head is surmounted by a twelve-pointed star. The edge of each point serves as the style of a small polar dial, the dial plate of which is split over the two adjoining sides.

Then on the top of this astonishing dial, there are two equatorial dials, on the top and on on the bottom faces of the star. Altogether, this sculpture carries 34 dials. More pictures of the dial thanks to Frans Maes and The wonderful moated manor house (image courtesy Gouwenaar - Own work, CC0,


The Rousham Sundial is February's dialling 'find'. A lovely small sundial by Dolland set in a wonderful garden designed by William Kent in the 18thC.

Rousham remains one of the few gardens of this date to have escaped alteration, with many features still to be seen such as the ponds and cascades in Venus’s Vale, the Cold Bath, the seven arched Praeneste, Townsend’s Building, etc, etc

There in front of the dovecote - or more correctly, the pigeon house - stands a lovely horizontal sundial by Dolland which is registered with the British Sundial Society as SRN 5989. See a few images here

The Cannon Bridge House Sundial - Revealed!! This is rather a hidden gem in London. cannon6_small.jpgPart of an immense Roof Garden that once was open to the public this is now a private garden - about an acre in area!


When open it was available for hire for events in London but now it is sadly closed and only very rarely available to view.


SunInfo has however been able to obtain a few photographs of the garden and - more importantly of the dial - and these may be seen by clicking on the image here or on our link to our Cannon Bridge House page. A rare opportunity to see this particular dial - and one by a relatively unknown modern maker too!  Can you help identify the maker?


A Courtesy for Meridian Line users provided free by Spot On Sundials! The original brass Spot-On Sundial was designed by Piers Nicholson and introduced to the market in 2001. Since then, more than 900 customers all over the world have bought them as presents for big occasions or simply for their own pleasure. To help enable the set up of any dial Piers also produced a very handy web based Time of Noon calculator Here.  It's also useful as a free resource when predicting when the image of the sun will pass any meridian line in the world!   The table produced Here shows the local clock times (CET) for solar Noon every day of the year for the meridian line in the Basilica S. Maria degli Angeli e dei Martiri in Rome which is at 41.9031N, 12.4969E. Just add one hour when your sighting is during summer when CEST applies.  Neat.

Is there a Trifilar Sundial? A query was raised Triflar sundialrecently on the sundial mail list as to whether or not a Trifliar Sundial was possible.  It turns out that it exists! Bernard Rouxel of France designed it.and got him second prize in the Italian "Le ombre del Tempo” contest of 2008. It is here limited to showing true Noon and the date.  Read Fer's article by clicking on the image to download the PDF of it courtesy of the Dutch Sundial Society and Frans Maes.

Luigi Ghia recently posted to the sundial mail list a link to a
computer animation showing Rouxel's trifilar dial in operation.

This animation was made by him with help from Tonino Tasselli and it has been computed for the summer solstice.
On the sundial plane the shadows of the three wires crossing each other, form a moving triangle. The triangle becomes smaller and smaller until it collapses into a point exactly at noon.
The point where the triangles collapse during the year migrates up and down along the green lines in the animation so this line is the meridian line and it may easily be annotated with dates or zodiac symbols.

A different arrangement of the three wires (for example with a rotation of the whole wire system about the polar axis) sets the triple crossing point at different points along the hour lines other than noon.

Revisiting a Triple Horizontal Dial Not to be Triple Horizontal Dialoutdone by the trifilar dial design above it seems appropriate to revisit John Davis's remarkable and ingenious Triple Horizontal Dial made some time ago for a client in Redwood Valley USA. It comprises a double horizontal design rather after Henry Wynne but adapted for the more southerly latitude by moving the second scale Northwards. The centre of the dial revealed by this process then is used to display Pacific Solar Time where a nodus allows five family anniversaries to be displayed.

The 'Dials' of Konark. There is a 13th-century sun temple at Konark near Odisha, India which is attributed to King Narasimhadeva I of the Eastern Ganga Dynasty of about 1250 AD. Dedicated to the Hindu sun god Surya, what remains of the temple complex is a 100-foot high chariot with 24 immense wheels drawn by horses, all carved from stone and quite accurately aligned E-W. Once over 200 feet high, much of the temple is now in ruins. The structures and elements that have survived are famed for their intricate artwork, iconography, and various themes. The wheels, spokes and other divisions of the wheels are arranged in a form and number similar to modern time keeping and consequently they invite use as sundials.  A simple calculation of the angles of the spokes between 6am to 6pm on the South wheels shows why.

The 2017 Report & Annual Accounts for the British Sundial Society have recently been published and may be examined at the Charity Commission Website or here courtesy of the CC.  Compared to the position in 2016, they show a reduction of overall income in the year of £3,258 and at the same time an increase in expenditure of £2,053. As a result, only £2,192 was added to Total Society funds in the year. Fees for independent examination of the accounts and (new for this year) for professional preparation of the claim for gift aid, have this year soared by 127%.  Indeed, something approaching 8% of all membership fees currently appears to be being spent on such bought-in professional services.
Comment received from a SunInfo reader:
"I am at a loss to understand how they justify spending on professional services"

Unusual Dial in Grantham  We were first made aware of this interesting dial in 2017.  It is in the one-time 'Clockmakers District' of Grantham at the junction of Welby Street and Westgate. It was delineated by Charles Westwood in 1790 as a west declining dial that would also show the equinoxes and solstices. It has only relatively recently been recorded in the National Sundial Register where its reference is SRN 6705. Unusually for such an old dial it still retains its original pin nodus.

STOLEN! Do you suspect that a dial known to you might have been stolen? Sadly many dials have been over the years.  A few recent thefts are mentioned in the boxes below.  The BSS has a list of stolen dials (sadly not updated since 2010) which is accessible here. There are some 44 dials listed.  If when you can get to see them and you recognise any, do let the BSS Registrar know.

2014 STOLEN! Thieves stole a sundial from a plinth in a Morley churchyard, where it had stood for 250 years.
The dial had been made by clockmaker and scientist John Whitehurst and had been in the grounds of St Matthew's Church, in Church Lane, Morley.
The instrument, which was made from bronze, was reported stolen on Sunday, February 23 2014 and had last been seen at the start of January. Please inform the webmaster if you have seen this dial.


2014 STOLEN!  Thieves in Blickling Hall's secret garden lifted and made off with the sundial and pedestal which is of carved Portland stone and stands 113cms high.
Jo Bosch, Blickling’s marketing and visitor manager, said the bronze sundial a replacement for an earlier dated from the late 18th or early 19th century, had a metal plate on it which said “Brookbrae Ltd, London”.
The theft happened between 10am on February 6 and 10.15am on February 7 2014.
Please inform the webmaster if you have seen this dial or pedestal.

STOLEN! An historic vertical sundial (National Register No SRN 2136 - click on image) has been stolen from St Mary's Church in Prestwich, Manchester. The dial is dated 1781 and is a vertical direct south dial which carries the motto "Sic Transit Gloria Mundi". There is some confusion as to the material of the dial; it may be stone or iron. Anyone with further information should contact the police, the Vicar ( and send  a copy to Another (B&W) image here

2014 STOLEN! Police are appealing for help in tracing a valuable sundial stolen in Sunderland between noon on Monday, May 5, and 2pm on Friday, May 9, 2014 from a rear garden.
The stolen sun dial is a distinctive brass Grande Armillary Sundial Ensemble, 56 inches tall, believed to be as per the image and made by Henri Studio of Illinois, USA. It is worth hundreds of pounds. Click on the image here for a larger view.

2014 STOLEN! Police are hunting thieves who stole a unique decorative sundial from a £4 million mansion near Potters Bar., Herts
Between Dec 22 2014 and Jan 18 2015, a large brass armillary sphere sundial disappeared from Rabley Park, a historic 12-acre estate in Packhorse Lane, Ridge.
Police say the large ornament can only have been moved by a vehicle.  It has several engravings, including “Do not squander time for that is the stuff life is made of’, ‘Clacton-on-Sea’, ‘Hemel Hempstead’ and ‘Newcastle’.
Anyone with any information should contact the police


2017 Grade II sundial STOLEN from Conwy churchyard

A Grade II listed sundial dating to 1761 has been stolen from a churchyard in Conwy and its stonework smashed.
The stonework holding the bronze sundial at Conwy church was smashed into three pieces.
Rev David Parry, vicar of Bro Celynnin, said the theft was noticed on Friday morning and reported to police.
"It's very sad. In taking the top, the thieves have severely damaged the stone. It's been part of Conwy's history for a long long time," he said.
"It's a well known landmark, listed in its own right, and we're at a loss to know why someone would want to damage this."    The dial is believed to be SRN 3262, dated 1765, 360mm dia includes an EoT scale and was made by Mereidh Hughes, of Conwy.


The NASS 2019 conference was held in Denver, Colorado 20th - 23rd June 2019. It included presentations and a tour of sundials. Early registration is recommended at the Hilton Garden Inn - Denver Downtown. NASS had a discounted rate of $179/night (plus 15.75% tax). This rate applied 5 days before and after the conference if rooms were available.

Full NASS registration until April 14th was $310-$322 depending upon dinner selection. After April 14th the cost increased to $335-$347.

BSS Bath Conference 2019 This year the conference is being held at the Bailbrook House Hotel in Bath from 26 to 28th April. One of the top hotels in the city, Bailbrook House Hotel is an historic grade II* listed mansion, located just a few minutes from the centre of historic Bath with on-site complimentary parking. As BSS is an English Charity  the Conference is Open to all, not just to BSS Members.
Day Delegate Rate - £160
Full Package for two nights Double - £525 Single £340
Extra nights - £95 single and £135 double. 

 NASS (The North American Sundial Society) held its 2018 Annual Conference from Thurs 16 Aug - Sun 19 Aug in Pittsburgh, Pennsylvania, USA. The conference was held near the famed University of Pittsburgh campus with its Cathedral of Learning at the Hilton Garden Inn, Pittsburgh University Place 3454 Forbes Avenue, in Pittsburgh. Read the Conference Blog here.

The BSS Conference 2018  took the Society to Norwich - to the Maid's Head Hotel there. The Conference ran from Friday 20 April to Sunday 22 April, 2018. See a summary of the  BSS 2018 Programme. Only 57 delegates attended. On arrival one of two short walks were  planned in Norwich itself for the Friday afternoon and in what for many was a welcome break from recent venues there was a coach tour to view David Payne's sundial trail on the Saturday afternoon. See more about what dials were seen. Full package prices were £340 for single occupancy, £520 for double. The Day Delegates rate is £160. As usual the conference was open to non-members as well as members and at no difference in price. See the delegates out on the tour.

The ULTIMATE Sundial Conference of 2017!  2017's year's NASS Sundial Conference really was the one to visit. 


The meeting took place in the Clayton Plaza Hotel, 7750 Carondelet Ave, Clayton, Missouri 63105 August 19-22 2017.  Why was it the ultimate one to attend?  Well, during the conference there was a total eclipse of the sun!  Delegates enjoyed 3+ days of gnomonic presentations and sundial discussions.  There were some tutorial sessions for  Aug 19th and the tour this year was very special with a ring side seat to watch the August 21st Solar Eclipse. NASS had reserved space at Jefferson Barracks that allowed an unobstructed view of the eclipse away from the expected crowds..

Check out  our page about the 2012 BSS Cheltenham Conference; a conference that was held over eight years agoThe level of interest is little short of amazing.  Mind you, our page does include summaries, photographs and the results of delegate opinions  - sadly things that are no longer published about its conferences by the current BSS Council.  Indeed, and by way of example, there is still no website entry of consequence on the BSS site about the 2013 meeting in Edinburgh nor one about the 2014 Greenwich Conference nor the 2015 Nottingham one nor the 2016 Liverpool, nor even yet the 2017 Oxford meeting nor that of 2018 either.  Why ever not you may ask?  Well, it might appear to you as a desire for secrecy. A number of issues arose at the Cheltenham conference which may be behind what appear to be moves by the present Council towards ever greater secrecy about their many blunders. Blunders that continue to surprise the dialling community. Their omission from their notes of the problems with the membership survey, of Graham Aldred's evidence in the Christopher Daniel book saga, the successive losses of society assets and their recent quite extraordinary attempts to block you from linking from this web site to theirs.  Hmmm, Shakespeare's Hamlet (1.4 [90]), Marcellus to Horatio comes to mind...

 BSS's Net Current Assets Fall 5¼% in a year.  The Charity Commission has received BSS's accounts for 2015.  For those wishing to see how the Society fared in those past twelve months, they may be examined Here.

A drop of 5¼% in Net Current Assets has been reported in the last year


It is thought largely to be because of conference losses.  Earlier Accounts can be conveniently checked and compared in our Document Archive below, see the section 'Policy, Guidance, Rules, Information Sheets & General Documents'.

An early English 'Scientific' Sundial with exactly calculated, unequal hour angles has been discovered at Scadbury Manor, home of the Walsingham family.  The very family that was so connected with the Tudor Court.  More information here.

 The Rostov 'Slab' discovered in 1991 may, it now seems, be an ancient Bronze Age attempt at a combination of sundial and moon dial.  The slab is marked with round divots arranged in a circle, and an astronomical analysis suggests that these markings coincide with heavenly events, including sunrises and moonrises.  Larisa Vodolazhskaya of the Archaeoastronomical Research Center at the Southern Federal University in Russia suggests that the people in the Northern Black Sea region were astronomically savvy with a technology on a par with what was seen in ancient Egypt around the same time.  Amazing, more information here

Sundial replaces Floral Clock at Swadlincote's Eureka Park in Derbyshire.  Sited in the same place as the original 1937 floral clock, a new sundial has been installed as a part of restoration work being carried out on the whole park by South Derbyshire District Council and funded through a £547,316 grant from the Heritage Lottery Fund and the Big Lottery Fund.

Key facts about BSS.  Here are details of the Society, the members of its Council and its management, its appointed and excellent Specialists, how to access its website and its Facebook page, how (and why!) to join the Society, how to send payments to BSS via credit card or PayPal and many recent annual accounts.  In fact more or less everything you need to know about BSS is here - warts and all! There's even help for BSS Members who may like to understand the background to the worrying oddities in today's erratic management of the society.

BSS's "1960's" management approach.  In October 2011 the incoming secretary of BSS suggested using a S.W.O.T analysis of the Society's Strengths, Weaknesses, Opportunities and Threats.  This is now a rather discredited approach to management (because it can actually limit performance) which was first mooted in Stamford in the 1960s. It is therefore more used nowadays to summarise the outcome of a more professional  analysis of a business. However one good use of it is to provide an historical perspective and allow outsiders to judge for themselves what progress has been made in any intervening period. Two analyses were prepared in 2011.  Have a look at the more detailed of the two here and check which of the suggestions in it have subsequently been adopted and which not!

Quotes of 2013... From the UK Charity Bulletin No 122, May 2013 published by IEL - who happen to be BSS's appointed Independent Accounts Examiners:

Integrity: There's no better test of a person's integrity than their behaviour when they are wrong. (Marvin Williams).
Destiny: Don't confuse poor decision-making with destiny. Own your mistakes. It's ok; we all make them. Learn from them and move on. (Steve Maraboli)

Now, even after 2017 might not these form useful advice for today's BSS Council - and from their own Examiner no less?

Greenwich Dial 'Restored' by BSS President Christopher Daniel!  In 1969 the 'Meridies Media' noon mark mean time sundial, designed by Dr Tadeusz Przypkowski, with amendments by Christopher Daniel, was installed on the south wall of the Meridian Building in what was then the Old Royal Observatory at Greenwich. Over the years it deteriorated and had to be taken down. In 2009 a movement was started to reinstate a replica. Chris Daniel, who had been curator of the sundial collection of the National Maritime Museum at the time of the original installation and who is now the President of BSS, was asked to design the replacement. This he has undertaken without a fee. The dial was formally opened by BSS Patron, Sir Mark Lennox Boyd on Wednesday 10.10.12 at 12:30pm. It represents a fitting Diamond Jubilee dial in Greenwich Park.  Some early notes about the replacement are here and further details of the ceremony can be found here. An image of this dial appears in the Wikipedia article about Sundials.

New Images and an article are available of the most recent dial commission by BSS President, Christopher Daniel MBE.  This is the Noon mark on the Guildhall in Faversham, Kent which was declared 'open' by the Town's Mayor in April 2013.  We are now pleased to be able to present a photogallery of the results of this commission and an article about it.  More details in the panel opposite (see: "The Faversham Dial"), or go straight to our Faversham Photogallery and/or to Chris's  Noon Mark article.  To learn even more about this sort of dial consider joining the British Sundial Society.  You will surely not regret it.

Odd how sometimes you might not get a reply from the BSS Trustees.  Here, after four years and coming up to five, is one of those.  In the past the trustees have objected when their professionalism has been questioned yet STILL there are examples of quite serious blunders which some might think of as being in this category.  The related issues with the permanence of the Library and with the President's book collection mentioned above are probably two of the longer lasting ones for members of the Society but the mistaken forwarding of financial transactions to a non-member is really quite serious, is worrying to those of us who place trust in charities and of course it is contrary to duty for any Trustee.  No apology or even an acknowledgement, has been received in respect of this letter - now nearly five years later.  More important is the secrecy with which this is enveloped - like so many of the other issues with BSS. Yet again, the membership of BSS have not so far been informed.  Why ever not?  Odd thing 'professionalism'.  Not much unlike 'Integrity' really...  There's more on the matter of BSS Integrity here



Linking to the BSS web site if you find you are being

'Forbidden' from doing so by BSS!

Direct hyperlinks to the BSS website from SunInfo were at one time being blocked by BSS. That stopped for a while when the new BSS web site opened but then from late 2015 some visitors to SunInfo reported that this was happening again. 


You might well wonder why any professional entity like BSS should want to make it hard for visitors like you to reach them. The more so when the advisory 'error' messages you receive actually says in print what they are doing!


All our visitors will know very well that this web site is, and always has been, very supportive of the concept and importance of a British Sundial Society; although it has never had any truck with the many apparent blunders, secrecy, cover-ups or obfuscations that some might have come to see as emanating from the Society today. 


The latest issue to report is, we feel, another rather unprofessional and ineffective attempt by BSS to bar linking from this SunInfo website (and not apparently from others) to pages of the BSS web site.  Clearly the concerns expressed by so many contributors on SunInfo  about BSS and its management must have real merit if BSS would rather you did not read them.


So, what is happening?  Who would ever want to block visitors from a website if there's nothing odd going on and especially when what is being said is true? 


Well, if you do find a BSS page 'Forbidden' to you - without any reason simply select the whole link, right click and select 'Open Link in New Tab'.  It's as easy as that! 


Sometimes you might get:

"The owner of this website ( has banned your access based on your browser's signature (24ddd725bccc3452-ua32). CloudFlare Ray ID: 24ddd725bccc3452 • Your IP: • Performance & security by CloudFlare" .

In this case simply set your browser to Incognito and go back in.


You can also go to our special links page BSS links .  Indeed, this new SunInfo links-page is now in a limited way, a sort of 'One-Stop-Shop' for some key BSS pages; so you can use it from within SunInfo to peruse as many of the provided pages of the BSS website as you like.


Give it a try and thank you for staying with SunInfo.  It is very much appreciated. 


Remember: SunInfo does not restrict linking to any of its pages by any website and SunInfo reports facts.

The Nice Dials of Newstead  There is a wonderful ruined abbey in the Gothic style at Walter Baxter [CC BY-SA 2.0 (], via Wikimedia CommonsMelrose in Scotland.  It was no longer maintained after 1544 and indeed it is recorded that the last monk there died in 1590.  Part of it was destined to rise again to be used as a parish church from 1610 -1810 and it was presumably in this period that many stonemasons were needed.  Whatever, it is recorded that many of these stonemasons lived and were trained in the nearby town of Newstead and whether or not that is the reason, there are several stone sundials in Newstead mostly dated to the 1650s - 1780s. Denis Cowan (of course!) visited Newstead in 2011 and he later published a fascinating article about these dials in the BSS Bulletin.  Well worth a read. There is at least one with its mason's mark, one was previously thought to have been a date-stone and one that is now stored out of the weather. Nonetheless there are two still thought to be missing. Maybe they are yet to be found?

 There are two vertical declining dials at Grimsthorpe Castle!  Historic England's Listing Details for Grimsthorpe Castle in the parish of Edenham in Lincolnshire, appear to only show one vertical declining dial at this property, yet there are two - both in 'reasonable'  condition for their age.  More than that, the larger one is still showing accurate Local Solar Time too.  


Read a little about the castle, find out where the dials can be seen on the building and have a look at two photographs of them. Then, marvel at just how well the larger one is telling the time even today.  All here.


Check out the dials on the Burlingham Walks of Norfolk. Courtesy of Annabel Payne, see the new website, which covers some of her father David's dials that have been carefully located in the woodland trails located North of Lingwood Village. The 3,000 acre estate was acquired by Norfolk County Council in the early years of the 20th century and became part of a scheme to provide farms for heroes returning from the First World War.

A 17th century brass sundial was prised from its stone plinth outside the front door of St Tysilio's Church between Llanymynech and Four Crosses in Powys. Churchgoers noticed it was missing on January 11 2018 but they can not say when it was last seen. Dyfed Powys constable Rhodri Treharne said it was an unusual artefact that police wanted to re-unite with the church.
Mrs Carol Davies, churchwarden, said the sundial is about eight inches in diameter and a golden brass colour.

Register Ramblings
The Recorder & DialTime Publications

Register Ramblings was the name given to a one-time regular entry in the society's Newsletter. The column was started by Patrick Powers when he took over as Registrar in 1997 with the purpose of keeping the membership informed about progress with the National Register of sundials. It was produced during Patrick's 10 year tenure as Registrar from the beginning of 1998 to the end of 2007. All are in Word 2003 format. The Newsletter column has been continued by the current Registrar (John Foad) under the title Register Notes. Some of his more recent editions may be seen on the BSS website.

Register Ramblings: A zipped archive of all 37 issues of Register Ramblings

The Recorder: was a four page colour magazine that was issued to delegates at each BSS Spring Conference and which served to comment on issues of interest to Dial Recorders and the general membership alike.  It was instituted by the then Registrar (Patrick Powers) at the Yarnfield Conference in 2003 as a way of giving something  back to the recording membership and it was published annually until 2014.  A PDF version was usually prepared each year and placed on the BSS website so that those who could not get to the Annual Conference were still be able to read it. The Recorder was edited and published by the Society's Registrar of the time. Here are links to them. There was no edition of the Recorder published for 2015 at which point SunInfo's DialTime 'took over'.. |Tips for the preparation of the Recorder|

DialTime: is by way of being a similar publication to the Recorder but is published intermittently (usually annually) by SunInfo.

BSS Policy and Charity Guidance, Rules, Information Sheets, Society and other Documents

The Society was indeed fortunate when Graham Aldred took over as Secretary for he transformed the record keeping and policy structure of the Society.  Prior to Graham's Secretaryship there were few, if any, written policies or even guides for trustees and specialists.  Additionally and because of the Society's small size, past Council decisions had rarely been recorded by former secretaries other than in the (then unsearchable) minutes.  This section lists just some of the Society's approved policies, rules, guidance and other general documents that have been drafted or edited by various trustees as a result of his initiative.  All documents are included here with permission of their authors (or their editors at the time).  Policies may of course be changed at any time by a majority vote of the trustees; for this reason check before you rely on the minutiae of any policy. Where a policy proposal was agreed by the trustees without any change, the original proposal was sometimes used as the policy document. Since April 2011 one policy (that relating to Reserves) has been abandoned, even contrary to a prior agreement with the Charity Commission and without informing the Commission too.   Another (the Expenses policy) has not always been implemented as intended. 
These serious and disquieting issues led to the
resignations of two trustees in 2011/12 - the first resignations of trustees that the society has experienced in its history and despite these, both issues remain unresolved even now.

The BSS Chairman's Radio Interview!
Just a bit of fun

At the 2012 Annual BSS Conference held in Cheltenham, and perhaps rather mischievously, there was played a clip from a radio Interview that the Chairman, Frank King, had had with Chris Evans on Radio 2 on 28th March 2012.  It was about sundials.  It makes interesting listening.  Not only does it extol the interest that there is in sundials of all types but it proves to be the first 'interview' that Chris Evans has had where he did not ask a question!!  An mp3 audio version of the interview (it is 800kB in size) may be downloaded to your PC and played using Windows Media Player or another proprietary package like IrfanView here

Frank King's 2014 lecture

The opening lecture at the BSS 25th Anniversary Conference held in Greenwich on 25th April 2014 was given by Frank King and was entitled:
