Richard died in November 2016 - his obituary
is at this link and in the reference section below. However
recently it was discovered that his twitter account up to the time of
his untimely death has survived him. It was of course written for
his many followers and the topics range all over his interests from
daily events, television and to sport. His humour comes out
wonderfully in the many wry comments which also show his depth of
knowledge on so many topics. Those who remember him - and those

British Dial found in New Zealand?
A sundial originally
for use in the grounds of Glamis Castle in Sotland -
childhood home of the late Queen Mother - and probably taken to NZ
as some sort of 'not now functioning' trophy has thrown up
aspects of Scottish dialling in the 17th and 18th centuries.

The Mystery of The
Dial in Dial Lane
Over in Aldeburgh,
there is a most interesting dial on the wall of Dial House. It is
known to the National Register as SRN 0596. It carries the motto
'Semper Fidelis'under the thriving foliage
HERE. It is a painted
vertical west declining dial - declining about 10 degrees - but it
has an elaborate metal(?) gnomon support in the form of a cast
four spiked sun which also appears to show some of the hour lines.
However these do not (seen from this angle) appear to align with
all of the painted hour lines lower down. Could this gnomon
support have come from another dial or perhaps the painted lines
are not accurate? Sadly the sun was not shining in this otherwise
very this clear photograph so the dial's accuracy could not be
determined. If any diallist can throw light on this matter
do let the webmaster know. Click
HERE or on the thumbnail
to see a larger version of the image.
this article was first posted 'Dial-finder extraordinaire' Ian
Butson has submitted his own close up of the gnomon support and
kindly given SunInfo permission for us to show it. (HERE).
It indicates that it was probably at the head of an original
Vertical South dial and from the slight damage at the top left, it
may well be hollow rather than solidly cast. Ian also wondered if
the material was lead. Given the slight rusting of some screws in
the surround, rather than the
body, it might seem that the top scrolling is separate and
possibly made from galvanised steel. How provision of no
fewer than 18 mounting holes - just for the gnomon support came to
be provided remains a real mystery. The present gnomon is not
fitted to align with any of these earlier lines. It has the
appearance of being possibly from a continental dial, perhaps of
Austrian, Italian or maybe German origin. Any reader who can
contribute more to this puzzle should contact the webmaster.

The Hidden Dial of Ham House
Ham House is a 17th-century
set in formal gardens on the bank of the River Thames in Ham,
south of Richmond. It was completed by 1610 by Thomas Vavasour, an
Elizabethan courtier and Knight Marshal to James I, but came to
prominence during the 1670s as the home of Elizabeth (Murray)
Maitland, the Duchess of Lauderdale and Countess of Dysart and her
second husband John Maitland, the Duke of Lauderdale. Originally
the house was constructed in an 'H' shape.
retains many original Jacobean features and furnishings and is
claimed by the National Trust to be "unique in Europe as the most
complete survival of 17th century fashion and power." Today it is
a Grade I listed building
Lauderdale was granted by Letters Patent full freehold rights to
the Manors of Ham and Petersham and the 289 acres of leased land.
In 1672 Elizabeth and Lauderdale were married, and, with
Lauderdale's part in the CABAL, the family remained close to the
heart of court intrigue. The couple made extensive changes to the
house from 1673 extending the house into the south part of the
"H", making it "double pile", two rooms deep, across its breadth.
This filling in of the 'H' shape was what caused the original
painted declining sundial to be hidden but not destroyed. An
edition of the recent TV programme 'Secrets of the National Trust'
allowed a glimpse of the dial showing the 4am mark and part of the
scroll of the motto.
to glimpse two images of part of the painting of the dial.

Is Pluto really a planet after all?
Scientists are now coming to argue that the
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

Some climate scientists still struggle to cope with people

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:

The Queens' Dial
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.

The Dial of William Hughes of Bryngola.
In what can only be
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.

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.

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.

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

Medway Council eliminates one of the Nation's most
important sundials! In an
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

The National Trust and the 'Housewife's Trick'?
The garden at the wonderful Wisbech
'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?

The Dial at
Another lost original dial has been replaced at
Court in the garden there. Heather Muir created the wonderful
garden, which until 1920 had consisted of a paved formal garden in
front of the portico.
Heather was helped and inspired by her
lifelong friend Lawrence Johnston of Hidcote Manor which is
close-by but it was Heather who decided that the garden should
develop organically, rather than by planning everything firstr.
This has given the garden a distinctly feminine feel, almost in
direct contrast to the more masculine lines being employed by
Johnston at Hidcote. A more recent development has been the
addition of the new water garden that was once the tennis court.
The original dial has long gone and the inset in the top has been
strangely filled but the replacement dial has character. Click the

The gardens of Hidcote Bartrim in
are deservedly well known and admired by all. In 'Mrs Winthrop's Garden' there is
a sundial (SRN 5903) which has, like so many others,
suffered from theft over the years. Today's version though is
frankly a bit of a mess. Set on a lovely 1789 pedestal is a poor
modern dial of the wrong size and with a rather twee motto. On top
of that the dial is not properly aligned. How much better with a
better dial but how much greater the risk of another theft?

my study" by Riccardo Anselmi
The author describes the steps followed
in the construction of a reflecting sundial, with the lemniscate
for the mean time, on the inside wall of his study. The sundial
calculation was performed with the help of the software Cartesius
Web, which can be used directly from the web browser.

3. "Sundials to
<true> sunset: first achievements" by Gian Casalegno
In 2011, at the National Seminar of
Pescia, the author illustrated how to calculate, using the
software Orologi Solari, the profile of the horizon from DEM data
and then derive the lines of the hours to "true" sunset, taking
into account the surrounding reliefs. Here the first achievements
of this type are shown and the used method is summarized.

Two vertical sundials are presented and
analyzed, one facing almost South and the other facing almost
North, designed by the late Aimé Pauwels (models no. 68 and no.

gnomons, one for the morning and the other for the afternoon, and
the hour points arranged along an ellipse.
7. "The geometry
of bifilar and multifilar sundials" by Fabio Savian
The author proposes a geometric approach
to the study of equiangular bifilar sundials, with essential notes
on their calculation: a base to deal with the multifilar one, that
marking a single time, can work without a quadrant and uses as a
projective screen a surface with any orientation and shape.

approach to the Aimè Pauwels ellipse" by Elsa Stocco
The two-style sundial of Aimé Pauwels,
characteristic for its hour points placed on an ellipse, as
described by Reekmans also in this number of OS, is explored with
the use of Geogebra, to answer the questions: 'why an ellipse' and
'how to build it'.

the private house where they were then being held was being

appropriate was the fact that at Bromley House there is both a
meridian line and a Pilkington and Gibbs heliochronometer. Graham
spoke with a trustee of Bromley House who happened to be attending
a talk at a BSS meeting and an agreement was subsequently reached.
Graham then personally repaired and serviced the Pilkington and Gibbs dial -
it turned out that the EoT cam had been wrongly fitted - and now

In order properly to orient a sundial,

The Möbius Strip Noon-Mark at Brown University
Several years ago (in the
Brown University alumnus Charlie Giancarlo presented
students at the University’s School of Engineering with a grand
to fund the installation of a sculpture to be placed in front of
Brown’s new Engineering Research Centre. He envisioned something
that would represent the rigour of engineering work, but have
artistic beauty as well. He wanted something that people could
touch and interact with, yet would last a long time, at least as
long as the engineering building itself. Most importantly, he
wanted it to be a means of telling time by tracking the sun — a
sundial. He challenged students to come up with a striking design
that met all those criteria and to then oversee its fabrication
A student group
took up the challenge, and the result of more than two years of
work — a stainless steel Noon Mark measuring 15 feet long and 4
feet high — was recently installed. The piece, titled “Infinite
Possibility,” is in the form of a Möbius
Strip with a Noon Mark analemma at one end..
Napier Dial At the southernmost
tip of Africa, about two hours drive from
lies the town of Napier, a natural and historical delight for
visitors to South Africa. This little town lies at foot of the
Soetmuisberg Mountain Range and is home to many tourist
attractions, not least the Napier Sundial.
Locally accepted as the largest sundial,
as well as the only vertical one, in South Africa.
The Napier Sundial was erected by Danie
du Toit in 1965, after years of observing the movements of the
sun. It was when he read an article written by CJ Langenhoven on
sundials which had been reprinted in 1936, that his interest was
piqued. This sparked in Du Toit a special desire to create his own
sundial. Click on the thumbnail
image for a larger version.
He duly approached the local
municipality, which provided the materials and allowed him to
erect the sundial outside the Municipal offices. It took him 18
months just to complete the markings for each minute - all based
solely on his observations of the shadow on the dial. A most
unusual example of a dial being constructed by observation.

and it represents the diverse history of Coulsdon whilst
acknowledging ‘noon’ not so much as 12pm, but the moment when the
sun is at its highest point in the sky above that specific place.
Richard Jackson, a committee member of
the residents’ association, called the sundial “exciting”, and
said of the designer of the dial: “Holly Graham has produced a
work of art that used historical documents left by the hospital
residents, which includes a useful sundial.

GARDEN’S HIDDEN SHOPPING VILLAGE
When Seven is Six! Seven Dials was
laid out by Thomas Neale, MP in the early 1690s, who cleverly laid
out the area in a series of triangles to maximise the number of
houses as, at the time, rentals were charged per foot of frontage
and not per square foot of interiors.
The names of the
seven streets were chosen with the intention of attracting
affluent residents, however some of the names have subsequently
been simplified or changed because of duplication with other
streets in London. They were originally: Little and Great Earl

(now Mercer Street), Queen Street (now Shorts Gardens) and Little
& Great St. Andrew’s Street (now Monmouth Street). Some of the

corrected a decades-old misconception about the famous
relationship between the Ara Pacis, consecrated in 9 B.C., and the
Obelisk of Montecitorio, a 6th century B.C. Egyptian relic that
was brought from Heliopolis to Rome by Augustus, the empire’s
founder. The researchers’ models revealed that the true
significance of the interaction between the monuments was not
after all, the shadow on the Ara Pacis, but the location of the
sun itself. Simulations showed that the Ara Pacis and the Obelisk
of Montecitorio were aligned so that, when viewed from the nearby
Via Flaminia, the obelisk would appear from behind the Ara Pacis
with the sun positioned at its tip. This celestial phenomenon
would have occurred not on Augustus’ birthday but on October 9,
the date of the festival of the Temple of Palatine Apollo.

A Tale of Two Dials
Our picture here shows the very famous dial at Queens' College
but there was once a very similar look-alike in Copenhagen; so
similar that a natural question arises as to whether one
influenced the other, or whether they are both descended from some
It is not known who designed the look-alike
dial design but it is currently attributed to Christen Sørensen
Longomontanus (1562–1647), a pupil of Tycho Brahe, who became
professor of mathematics in the University of Copenhagen in 1607.

WD& HO Wills
Several decades ago the cigarette companies
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

We last visited this dial in 2018 but it is always
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.

The Dial at Fountains
Fountains Hall is a Grade 1 listed country house in

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

The History of the
Here's an interesting article about the
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,

charitable gift is still in existence and is managed as a named

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
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.

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

Sad Dial at the Lygon Arms Hotel.
The Lygon Arms Hotel in the Cotswolds
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

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.

Sundials of the Castle and Collegiate Church of St. Michael
of the city of
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,

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.
The Delightful Dial of Dalemain in
Cumbria The well known octagonal dial
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.

The Hugget Heliochronometers
Brian Huggett and his wife enjoy visiting gardens, in
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.

A chance to see a real Merkhet
The Merkhet (or merjet "instrument of knowing") was an
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

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

The amazing Coade Stone Dial Discovery -
AND we made it!! Recently Weston
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

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

Hitchin's Physic Garden Sundial This month's dial is
the most unusual one that is in
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 designed and made by Joanna
Migdal (now Lady White).
A Fine Example of a Cross Sundial has been located
in the SE of England. It is a particularly elegant example
a rare dial type since only some 35-40 such dials are known in the
This dial further excels in having its own equation of
time scale on its 'front' (South) face, a motto on its base and time
markings of 30,15 and 5 mins.

his recent presentation entitled A Novel Sundial with
Double Indicator and Calendar. This novel dial solves the
"sundial problem", it shows the time to the minute and the date to
the day over the whole year without intervention.in addition the
dial is universal. It can be placed at any point on earth where it
will show the time from sunrise to sunset.

The Moot Hall Dial
In Aldeburgh in Suffolk, now very
to the sea stands the lovely
Moot Hall which today houses the Aldeburgh Museum. It
is a superb timber-framed 17C building, erected by the Burgesses
of Aldeburgh at a time of great prosperity as a manifestation of
civic pride. Today it is still treasured by the people of
Aldeburgh as the centre of their community and a symbol of their
heritage. The dial
declines about 14.4 degs W and shows a little 'restoration drift'
as may be seen from a
comparison with a recalculated image of the hour
lines. Please do explore the links given here to appreciate this
lovely Hall and its dial.

Suffolk. It is a West declining dial with four declination lines
and it is quite elegantly designed, presented and maintained.

The Dial at Bosworth
After the remarkable
of the remains of King Richard III a sundial was designed to mark
the event, his life and legacy. In August 1485 King Richard
III was killed at the Battle of Bosworth, and buried by the Grey
Friars, a Franciscan Holy order, in their friary church. In August
2012, Leicester City Council, the University of Leicester, and the
Richard III Society began a search underneath a car park in
Leicester, to find King Richard III’s remains and the Grey Friars
Church. This coincided with the 527th anniversary of the date King
Richard III was killed at the Battle of Bosworth.
after the dig began, the University of Leicester confirmed a
skeleton unearthed by archaeologists was in fact Richard III.
Later a sundial was commissioned. It has a central gnomon topped
with a crown. At ground level is an inscription which tells the
story of the Battle of Bosworth derived from the chronicle of
Polydore Vergil, an Italian at the court of Henry VII. The sundial
marks the points of the compass and the distances to other
battlefields of the Wars of the Roses. Around the outer dial are
three thrones bearing the names of Richard III, Henry Tudor, Earl
of Richmond and Thomas, Lord Stanley. Click the image or

Is there a Trifilar
A query was raised
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

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.
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
Not to be
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.

There is a 13th-century sun temple

Unusual Dial in
We were first made
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

The level of interest is little short of amazing. Mind you,
our page does include summaries, photographs

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

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

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

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
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
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.

Just sit back and relax!
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
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'

Linking to the BSS web site if you find you
'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
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!

The Nice Dials of Newstead There is a
wonderful ruined abbey in the Gothic style at
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!
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
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.
A 17th century
brass sundial was prised from its stone plinth outside the
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 is of a golden brass colour.
