Sites marked SS - 91, 92, 93 and 94 - represent the four Stonehenge Station
Stones (the diagram is from Castleden). Of these four sites, only one now
boasts a stone accurately in situ, 93, and only one other site, the 91 'recliner',
has a stone of any sort. For all that, much has been made of the four sites and
the rectangle they appear to produce.

Robin Heath - thanks!
3. Detail from Doutre
showing a rectangular
shape (of sorts).
Now the line connecting SS93 to SS91, the rectangle's hypotenuse (or one of
them) is interesting, to some, it seems. According to Bonnie Gaunt, THE MAGNIFICENT NUMBERS OF STONEHENGE AND GIZA, that line is at angle of 118 degrees East of North and pursuing it in that direction from the centre of Stonehenge and you'll end up at the Great Pyramid in Egypt:
- 'Sky and Landscape'. Robin mentions numbers that chime here: 23.52
and 33. However, something weird happens as regards Station Stones.
There's an expert: Aubrey Burl. Is that our Aubrey Burl? The one above
calling the lunar alignment 'imprecisely directed'? The one who placed the
right-angle in the sea, some 30-40 miles south of Stonehenge,
and the one who moved the henge a mile or so north?
C/o of Robin Heath, we come across 'near perfect rectangle' with the 'long
side aligned to the (northernmost) moonset'!?*
*I note Heath's 18.618 year cycle - and that it is often, loosely given as 19 years - and there are 2 events to consider,
not the one, I gather.
But that's not the biggie: I read of the Station Stones providing a 5 : 12 : 13
in one place and of them providing an octagon in another. Neat trick! Put
another way, which is it? Or is it both?
I've invited Robin to comment and will carry any relevant input I receive
- dated 11-09-07. Reply received dated 13-09-07 - thanks, Robin, you are
- and have always been a gentleman (and a scholar)! Robin remarks:
1. SS91 is the recliner and SS93 the upright! Exactly right - and apologies!
All I had to go on was information supplied me by the 'Visitor Operations
Manager - Support Services Stonehenge. This says QUITE the opposite
and places "93 in the SE quadrant" (which should have alerted me)!
3. Robin makes the point about 'apples and oranges' relating to one's
definitions (sunrise, for instance) - just as I do, below. Here is his response in
full (noting that the increasingly fuzzy and turgid doubtless means me!):
Sorry your page overheated itself.
Stone 91 is the recliner, not 93.
Midsummer sunrises/sets do not exactly oppose midwinter ones.
At the quarter days, and at the latitude around Stonehenge, consecutive sunrises and sets occur nearly a solar diameter apart - that's 31 minutes of degree. As these SS rectangle alignments are classed as symbolic (i.e. short distance) alignments, and we do not know where ( if anywhere) an observer in 2500 BC placed his eye-balls to use such an alignment, then it is not possible to publish a precise figure for the angles of the quarter day sun rises/sets. The quarter day in the length of the calendar year causes the sun's position to vary its rise and set positions for a given day from year to year. And in prehistoric times, the length of the summer half of the year was different to the winter half in different ratio to the present, a fact that many fail to account for. The laudable quest for precision is also doomed if the horizon elevations along each supposed alignment are not taken into account. Finally, are we supposing that the observer is interested in the first/last flash, a half-risen/set disc or the sun sitting with lower limb on the horizon?
The problem here is a little knowledge of the astro-archaeology is a dangerous place to go. Perhaps some anchor points, upon which a researcher can depend, are needed.
1. Alexander Thom's survey of Stonehenge and subsequent plan (1973) represents the best available data we have from the acknowledged master-surveyor of stone circles. Thom found the axis of the monument to within a few minutes to 50 degrees. In the Journal for the History of Astronomy, 1974, pt 2 no 13, he gives the azimuth of the axis as 49* 57'. Nothing whatsoever to do with astronomy, this is what his survey revealed from the avenue axis.
2. Thom (in the same JHA) measures the azimuth looking from station 92 to stone 93 as 'about 320 degrees'. Although 'about' may appear uncharacteristically vague for Thom's data, it is the relatively short distance between these two points, the lack of a backsight stone (92), no knowledge of the original width of the backsight stone, that makes it necessary to use the word 'about'. However, he noted that Gibbett's Knoll, a small tump on the flat high ground above Market Lavington, some 9.16 miles from Stonehenge, provided an azimuth of 320* 02' from station 92. Again, this is nothing to do with astronomy, it's geodetic land surveying data. For this longer distance, it matters little where the observer's eyeballs were placed. However, if this was a long distance foresight via stone 93 and station 92, and passing through the so-called Car-Park Postholes, this line would have provided a precision alignment to the major standstill moonset around 1900 BC
3. These two precision surveying alignments 'fix' the rectangle to the rest of Stonehenge. The difference between the axis azimuth and the station (92,93) line above is within 3 minutes of degree of being a right angle, a precision of 99.94%. It is hard to attribute coincidence to this level of precision. It may be relied on as accurate, because Thom was a first rate surveyor and this is acknowledged by archaeologists.
4. Only one station still has a stone in its original hole. The holes for the rest were determined by probing by Prof Richard Atkinson during the Thom survey. There is always going to be uncertainty in determining precisely where the centres of these stone holes were placed and we shall never know the exact points. Akinson's data and conclusions on the precision of the station stones were printed in John North's book, Stonehenge (Harper 1996). ( Peter Newham determined that the station rectangle was aligned to the avenue 'midsummer' axis (shorter sides) and to the major moonset (longer sides). Thom's plan confirms the stations to be arranged to define a 5,12 rectangle. Thom also gives the diameter of the Aubrey circle as 283.6 feet to within just under one inch. This too may be relied on as 'best data available'. The later station stones appear on the plan to have been placed on the line of the Aubrey hole circle, making the diagonal of the 5:12 rectangle, 13 units of the pythagorean triangle, the same measure. )
5. Thus, finally, it is perfectly in order to suggest that the latitude of stonehenge connects very well the geometry of the monument ( the axis and the station rectangle), and the astronomy of solsticial sunrises and major standstill moon sets. Burl may have suggested (1998) that the exact calculated spot lies in the English Channel near the Solent, but no-one has seen his calculation to check whether he accounted for refraction, horizon elevation, the date assumed nor the curvature of the earth.
6. Because we are dealing with a structure erected over 4000 years ago, we must face squarely Thom's bleak prognostication that 'only in exceptional circumstances may we expect stones to have remained in their original positions.' But precisely because of this, we are legitimised in attempting to make models of the monument that speak to both earth and sky. And speak they do, conveying a meaning presently denied by mainstream archaeology. Anyone who has understood the basis of the calendar outlined in my books will appreciate that the two principle circles at Stonehenge, the early Aubrey circle and the later sarsen circle have diameters related to the foot and the Megalithic yard. Prof North gives (correctly) the outer sarsen as 52.2 feet radius and Aubrey as 104.27 Megalithic yards diameter. These measures correspond with precision to the difference between the lunar year (354.37 days) and the solar year (365.242 days), a difference of 10.875 days), and the length of the lunation period (29.53059 days). That this fundamental astronomical constant is built into Stonehenge, as it is also built into the 5:12:13 lunation triangle and into every Type B flattened circle indicates that it is time to bypass the logjam caused by denial of prehistoric precision in astronomy and metrology, and work outside of the box. That work must involve the researcher in learning the mathematics and astrophysics to be able to spot the pitfalls that lurk within this subject. Otherwise all that happens is an increasingly fuzzy and turgid literature that obscures the subject - this suiting the present archaeological stance ideally.
7.Let me finish by making the reader aware that one cannot learn this subject - archaeoastronomy - in any UK University at present. That is why I run Sky and Landscape courses (www.skyandlandscape.com) to practically guide aspirants how it all comes together. For the past 20 years I have been taking groups to Stonehenge and other sites and they use what remains on the ground to accurately find the date, the phase of the moon and when eclipses will occur. Numerically and geometrically, Stonehenge is a perfect monument to express how to do all of these things. Eventually, more will be recovered, to be sure, but we actually already have a full cup that fully runs over.
Robin Heath
Back to fuzzy and turgid me:
after noting. as I just did to Robin, again, that that still leaves the question 5-12-13 or octagon!? Using the figures
cited (from Thom) we'd have approximately 283.6 (13) plays 261.7846 (12) plays 109.0769 (5) as against 283.6
plays 262 plays 108.53. In the context of the centre (eyeballs) of Stonehenge, the SS hypotenuses are said - I
have read - to either pick it out exactly or almost. So 'eyeballs' means (like with the point about definitions of,
say, 'sunrise')? There IS a convention, of course, these days, but it IS NOT a convention that deals in true horizons
- what you can actually see!. So 'Apples and Oranges'?
Also, note the 50 degree axis (off north) irrespective!? of the Midsummer sunrise azimuth and the (360 - 40) 'major
standstill alignment' in 1900 BC, pretty much NAO on the moon this year? That puts the standstill and the AXIS
(rather than the sunrise) at 90 degrees?
It is Robin himself whose site had a midwinter sun directly opposed his midsummer (See Fig. 4.3 above) - but a
quick check on NAO reveals, as the email notes, a June 21 49 degrees opposes a Dec 21 of 232 degrees. 180 + 49
is 229 ... 3 degrees! (plus or minus). Dec 21 to June 21 (exclusive) is 181 days whilst June 21 to Dec. 21 (same)
is 182 days. Leap years are 182 v 182.
Last year's April moon attained this 320 degrees - unlike values for 2005 and 2007 (NAO).
I have attempted to contact Dr. Burl with little success so far! Re-reading his 1998 article, though, I notice he calls the
idea of a right-angle twixt northernmost moonset and midsummer sunrise "incorrect" and I find a value of "50 degrees"
(the Stonehenge axis value to 3 minutes accuracy! Heath) accorded the Midsummer sunrise. That fits no-one else at all!
Burl notes the differentr azimuths for Midsummer sunrise and Midwinter sunset as 50 degrees and 319 - BUT THE SECOND NUMBER IS OBVIOUSLY A MOON VALUE AND NOT A SUN! What's going on? Is Aubrey Burl,
'Birmingham' a clue? Is this another Dr. Burl - the letter is so riddled with mistakes ... I'll query it with the periodical!
Emailed 15-09-07 to the current Editor, noting the minute extra north Lat., and the confusion northenmost moonset with
midwinter sunset, and I could also have mentioned 319 when it's 320, and his unique 50 sunrise value - where this 50
and derived 40 (360 -320) = 90!!!! Noting the absence of fractions, however, so plus/minus one degree possible.!?
CPC Note:
50 plays 40 is of no use to my CPC model (MOVING QUOITS) at all I need 51 plays 39 - whether it exists twixt
Midsummer sunrise and Norethernmost moonset OR NOT. I can look elsewhere for my numbers though - I can look
to "North" and "South".* How so? The Latitude you are standing on is pretty much the angle to the Pole Star, currently
Polaris. And Stonehenge is (comonly) at Lat 51 11* * Well, there's my '51', anyway. And my complementary right-angling
'39'? . First full day of astrological Aries and the astrological year, sometimes the Spring Equinox - this might be the '39'.
For example, NAO alues for 21st March 2003-2009 mean to 39.054.
* Equinoxes are also useful East-West markers.
**51 10 42-4 is better. A search threw up the range 51 10 36 to 51 10 42.35 (Carl Munck, 1992). Online Multimap
gives me 51 10 44 (approx. centre - but 'eyeballs' again - it's a big site!). The Longitude appears to be
1 49 34-ish (I think Munck gives 1 49 28). Wondere where I got the idea it was 1 51 from?
All in all, a thoroughly welcome and informative contribution and study, Robin. Thankyou. John Neal approached
16-09-07 - he knows quite a bit if I remember earlier email exchanges involving, also, ML Saunders, maybe 2 years
ago?
Assuming the positioning of the Station Stones was other than decorative in
intent, then all the ideas proposed are viable - given we only have the one stone
in situ and that this stone is nearly 4 and a quarter times smaller than the
'recliner', anyway (and "one of these may not be original." acc. witcombe)! Not
much here to provide anyone with proof positive ...*
*From English Heritage (thanks to Mrs Finola Andrews, PA to the
Stonehenge Director) comes this data:
91 2.6 1.5 1.1 13.1
92 1.9 1.3 1 8.1
93 1.2 1 0.7 3.1
94 1.9 1.3 1 8.1
You are looking at heights, widths and thicknesses (all metres) and weights
(tons). 91 and 93 are in bold because they actually exist. Data for 92 and
94 is pure speculation. There is no reason to suppose they were utterly
identical, for instance.
And that brings us to the actual rectangle dimensions themselves. They vary
(almost as theory to theory). If we take the hypotenuse value, say, then English
Heritage measures the distance at about 279' (from memory) to Bonnie Gaunt's
288'. Most values are in the 281'-283' range but I think Chris Witcombe carried
285' on his excellent and informative Sweet Briar College site (details below). *
Obviously, given Octagonal maths or 5-12-13, one dimension informs the rest.
Doutre, however is trapezium (UK def.) rather than rectangle proper, with
shorter sides given of 112' and 113.4' compared to, say, Gaunt's 115.1-ish'. Ralph Ellis, THOTH: ARCHITECT OF THE UNIVERSE (2001), carries measurements of the shorter, or 'adjacent', sides: 108.75984 ..' by Flinders Petrie and 109.25196867 ..' for Atkinson, this second being explicitly centre to centre (insofar as that is possible ans imperial values being derived by me from the metric given. Given the adherence of Ellis to the 5-12-13 model, the longer sides necessarily have to be 261.0236 or 262.2 .. whilst the hypotenuse value has to be either 282.775584 or 284.0551 .. The first, or Petrie value, falls within the normal range determined (by me) above.
* A value known to Ptolemy, C2nd AD. About then precession meant the sun was in Cancer and Capricorn at the Equinoxes - hence these being the names applied, although the actual placing no longer applies. How far back before Ptolemy the '47' goes I currently give in. **1515 AD is a date given by Gary, I notice. It is also the birth year of the man who 'invented' the letter j. When I first
saw the dates 1515-1717 given in Gary's REVELATION 2 (click on NEWS on his site, given below or
Professor Richard Atkinson - a 1978 measurement carried by Ralph Ellis, p. 141 Dr. Aubrey Burl - possibly the leading (and prolific) luninary in archaeoastronomy

Since this is the last page of the series, may I note here that the topics touched on are disparate threads of research which inform my MS MOVING QUOITS but don't necessarily make it into that (at least in any detail). This page, for instance will condense down to a few lines of particular relevance to the Glastonbury and Stonehenge vertices of the Michell Circle of Perpetual Choirs (CPC).
It is the MS that unifies these pages - I just had seven A4 folders of my (many years, now) studies which would have gathered dust had I not put them here for others to pick over as they wish.
One thematic line is 'right-angled triangle' - and Moggz's Whiteleaf Oak study encouraged me to look upwards: were there any significant to be found in the sky, I wondered. 'STATION STONES' provides some supportive material of the idea that there arguably were (well, nearly, anyway!) - I least I think the idea can be reasonably advanced. All the above indicates the lengths you need to go to in order to 'cover one's back' when writing even a few lines!
Take nothing on trust, I've learned. Check and check again - especially internet sourced material. One person has an 'idea'. Another carries it. Presto: two impeccable sources and, ergo, it must be true.
So much CPC investigation I've looked at suffers from 2 faults:
1. Instant gratification required by those 'seeking'. It's damned hard and mentally taxing work. It takes a long time and a strong capacity to pick yourself up, dust yourself off and start ...
2. Misplaced trust: I have little doubt in my own mind that a 'game' was played out over the English and Welsh landscapes in the C17th and C18th AD, and that this game carried the fingerprints of ancient mathematical significances and understandings. John Michell's work over the years have reprised these again and again - and inspired others, including, obviously, me.
But the Circle of Perpetual Choirs (CPC) isn't the point: there isn't and never was one, not as imagined by John and so sought by others with so little if any success (see 1.). The real point is the maths of the construct and the Latitudes, river and BOOK OF REVELATION it has been placed on. He Phren is the point and Hafren the site. Mirrors.
I apologise for this hastily cobbled together page. The previous incarnation
self-destructed at about 6.30 pm, Tuesday 04-09-07 - completely
spontaneously. Though a Japanese 'message' accompanied the event!
Shame, 'cos I'd just reached slot 2 on Google with what I intended to be
an open resource airing all thinking on the subject of the Stonehenge Station
Stones.
I will correct and extend - particularly links - in due course.

A few notes of interest, perhaps?
1. A 'John' (47) could therefore be said to indicate 1/2 a year, 2 Johns making a whole 12 month cycle Capricorn-Cancer and back?
2. Looking at 23.4 - and noting a right-angled triangle necessarily creates
66.6 - then note also the 'mirror' 43.2. Add to 23.4? 66.6 again.
Right-angled triangles crop up again and again and ....
If you think in terms of Capricorn and Cancer, the 2 Tropics, then the
angle below Capricorn and above Cancer will be?
66.5-66.6 X 2.
3. Given the differing dimensions above, I wondered for some time - and
in some for instances - whether it was an apples-and-oranges situation?
Station Stones occupy space. Measuring from different bits to different
bits would produce different outcomes. But I couldn't see anything
obvious in the dimensions of SS91 and SS93 to support the idea. I do
note here, however, that at least one commentator considers the idea that
the SS93 'recliner' hasn't just fallen over but has actually been moved!
4. 360/7 - James Q Jacobs provides this value for the centre of Stonehenge
out over the Hele Stone (off North - 51.428...). It is also, as he notes, the
Avebury Latitude. I have also seen the idea aired that the Station Stones
themselves provide a regular 7-sided star (as against Octagon or 5-12-13
234 is 2 X 117 and 10 X 23.4, leaving 66.6 to make up a right-angle. Put
another way, if the Capricorn and Cancer Tropics are 23.4-5, then the
dimensions above and below them are 66.5-6 X 2.*
For the puposes of the CPC model, the sunshine line will be the 51 degrees I
believe John Michell originally specified - albeit I am awaiting provenance
for this. Note: I have found "51" used by others this year (2008 AD) ...
*Note re 117 (geoffss, 01-12-07): it's a mirror (of sorts). 117 is 39 X 3. But is is also 13 X 3 (power2) ... and 1332 is 666 X 2.
Two diagrams: Planet Earth's Tropics and Stonehenge's Station Stones:
NOTES: 'the obliquity of ecliptic' etc. Planet Earth is off celestial 'up' by a (moving) anglestylised as 23.5 degrees = and this number is also (and again stylised) accorded the two Tropics, Cancer and Capricorn. These denote the limits of our year's seasonal cycle. The cycle is 47 degrees summer to winter and vice-versa.
The Stonehenge Station Stones have been called octagonal (22.5) and 5-12-13 (22.62). Ralph Ellis, THOTH: ARCHITECT OF THE UNIVERSE ... P. 160 (googlebooks) carries the ideas 22.5/22.6 together in the context of Stonehenge - and this value is indicative (or can be) of the lower value for the cycle of the Earth's "wobble" for which 23.5 is often used as a middle value (of sorts) - thanks for the refence, Gary.
The angle from the centre to the ends of shorter rectangle sides can be the same 47 degrees as with the Tropics. Here a a link to a fascinating study embracing the tropics, 23.5, Washington DC, the Great Pyramid and Stonehenge:
