20. The geometry of Holme II proved impossible to resolve without the aid of the megalithic inch. Furthermore, without the "inch," Holme II was impossible to build.
We also find that the timber posts respected the Stone Age 10-degree rule. I show those that aim at the cardinal points.
Geometry is based, as is so often the case, on a pair of near-Pythagorean triangles.
21. This Stonehenge model shows what the monument was meant to look like when and if it was ever finished. However, Stonehenge proved too complex to complete, with twin axes only 18 megalithic inches apart and stones already assembled getting in the way of those awaiting assembly.
22. The Society of Antiquaries produced this plan of the sarsen and bluestone building to show the result of restoring Stone 56 to the vertical in 1901. This was at a time when the society believed that its axis passed centrally through the gap of the Great Trilithon. It does not. We show the actual primary axis in dotted red.
The diagram appears to be a piecemeal version of Flinders Petrie's 1880 plan, and we have superimposed his plan in red to highlight the differences.
Petrie believed that Stone 10 was correctly placed, which led him to develop a figure for the internal diameter of the sarsen circle, which gives 35.75 megalithic yards after conversion. However, we now realise that Stone 10 is misplaced and that Stone 11 is the more accurate. Thirty-six is the currently recognised figure for its inside diameter.
Other points of interest are...
Stone 27 was leaning in towards the middle of the circle in 1901. Petrie's version correctly stands on the 36 MY circle.
Stone 22 fell onto Trilithon Stone 58 sometime between Petrie's survey and 1901.
The 110-foot scale is accurate, but the north arrow is over three degrees out.
23. John Wood's 1740 survey of Stonehenge is placed on top of a 1964 aerial photograph.
Professor John North stated that the 56 Aubrey holes were placed on a 104-megalithic-yard-diameter circle. Hawkins claimed it was 105. So, who is right?
Only 32 of the Aubrey holes have been excavated; the remaining 24 were found by thumping the ground with a mallet and listening for the hollow sound excavated soil makes.
Furthermore, to my knowledge, accurate cartesian coordinates of the 32 excavated Aubrey holes have never been made. And those measurements would not be passed on to independent researchers anyway!
However, a vertical photograph of Stonehenge was taken from 1000 feet up in 1963, which shows the painted-white concrete caps that cover the holes. Hawkins presents these photos in both of his books. Presumably, that is how he arrived at 105 for the circle's diameter. Otherwise, scales were not necessary or given.
The architect John Wood produced the most accurate survey of the stone building, which included the Heel Stone and the two remaining Station Stones, 1 and 3.
I have superimposed Wood's survey on top of the 1963 aerial photograph to scale it. According to Wood, the distance from Cypher A - (a small yellow circle) to Cypher R (another yellow circle) is 78.62 MY. (Cypher: Old English)
Interestingly, we can now see that the Slaughter Stone has been moved slightly inward since 1740, when John surveyed it.
More importantly, if not oval, Hawkins was right to claim the Aubrey Circle to measure 105 megalithic yards.
From the above, we can see that the Aubrey Circle exceeds Station Stone 3, showing that bosing the ground by thumping it with a mallet is pretty much useless.
I show some 50-degree lines that the Aubrey holes describe. There would be many more if all 56 positions were known. The position of the posts that mark the Cardinals would be known, too!
Did the station stones define the position of Stonehenge's primary or secondary axis?
It seems more than likely that the four stations were placed on the corners of a rectangle measuring 96 by 40 megalithic yards to give a pair of back-to-back triangles having hypotenuses equal to the diameter of the Aubrey circle. I.e., 105.
The centre point of this rectangle sits above the centre of what today is known as the Bluestone horseshoe. This centre is on the secondary axis.
24. The Stonehenge Avenue.
This avenue connects the river Avon to Stonehenge. It starts, not ends, from the West Amesbury henge and, by its geometry, carried a wish that Stonehenge would grow into something much bigger.
It starts at twenty degrees and becomes twice-sized at 40 when it approaches Stonehenge.
Also, the radius of the massive bend starts at 375 Megalithic Yards and grows to 750 before continuing to Stonehenge. Both arcs are straight lifts from Avebury's geometry.
What was the good of the Stonehenge Riverside Project?
The West Amesbury Henge was partially investigated in 2008 when nine of a possible 24 post holes forming a circle were excavated. The circular form of these nine holes is similar to Woodhenge and Stonehenge's Aubrey Holes and is difficult to ignore. They must have held timber posts, not bluestones.
The remaining 15 post holes are closer to the river. Some are in it. Wood survives well when kept wet. The 15 unexcavated post positions are begging for further investigation.
Our latest acquisition.
We have successfully deciphered the geometry of Ring C, Site IV, found inside the henge in the middle of the enormous henge at Mount Pleasant in Dorset. Site IV provides compelling evidence that it adheres to the enigmatic megalithic inch, as do rings D and E.
Following the arrangement of all five egg shapes at the heart of Site IV, the beaker people meticulously repositioned many posts. This resulted in the creation of several geometric shapes reminiscent of Stonehenge's artefacts of gold, as seen in the section on Stonehenge gold. This also explains the apparent misplacement of numerous posts.
25. The surveyor, John Wood Senior, famous for having designed the Crescent and Circus in the City of Bath, was the first to properly survey Stonehenge in 1740.
A CAD version (Computer Aided Design) of Wood’s survey, plotted in Megalithic Yards at the rate of 0.83 meters, is shown above.
John Wood Senior used Stonehenge to train his apprentice son, John Wood Junior, in surveying.
Requiring over 800 measurements, Wood’s 1740 survey has never been bettered.
Wood's survey is especially important for being produced before the collapse of Trilithon 4.
This plan was reviewed by somebody (Obviously one of the boys) who reviews books for a magazine about ghosts and has effectively shut my book "Stonehenge 1740 AD" down for working to six decimal places. However, those figures were produced on a calculator, and reducing them to please the awkward while maintaining accuracy would require more trouble than it’s worth.
