J. Rankin who posts at Thothistheibis asked, “Why are the Aubrey Posts at Stonehenge at a 6.428571 degree spacing? And have I seen the number before in my Torah research?”
First to bring myself and others up to speed on the Aubrey Posts: there are 56 holes inside the bank at Stonehenge I which have been filled in with chalk, debris and human remains. No astronomical purpose can be determined for them. The circle has a diameter of 891 feet. The holes are typically 30 inches deep and about 41.7″ wide.
The square root of 7920 (the diameter of the planet in miles) is 89 which seems remarkably similar to 891.
J. Rankin points out that 6.428571 is 45 divided by 7. It is also the square root of 41.32. No other meaning could be attached to it at this time.
The angle 6.428571 is derived from dividing the circle of 360 degrees by the 56 holes of the circle.
Which leads to: “Why 56 holes and what are they about?” There are many offered explanations available in the Wikipedia Article on the subject. The conclusion is that after many, many years and much study, no one can explain them.
Each and every ancient site appears to have a number associated with it. An obvious example is the Giza Pyramid. It is a five sided pyramid which means the site number is 5 but! It is truncated so it is 6 sided. 5 x 6 = 30 and you have its latitude and currently its longitude. The 5 and 6 also forms 56.
The holes were dug 30″ deep. 5 x 6 = 30, another use of 56. The diameter of the circle is 891 feet which gives a circumference of 2799.4 feet or 2800 feet. And we can see 2800 x 2 = 5600. Another use of 56.
The 56 does not appear to be astronomical in nature. It may or may not be just ceremonial. Further study is required for understanding.
Whereas Stonehenge with its massive stones is for watching the heavens, the outer circle with its 56 silent white markers were perhaps for ceremony and remembrance. The answer is not in the angle between them but the number 56 itself.
This is one of the most important numbers to be found in the Torah, yet it is quiet and obscure. It keeps its own mystery.
