Hi Jacob

Quote "By what process did Professor Thom confirm the builders of Stonehenge Aubrey circle were cognizant of and employed pi."

Thom may not have given a seconds thought to that question. Thom was pretty good at measuring though and most certainly noted the circumference of circles. For example Stanton Drew Thom made the diameter 372 feet 3 inches giving a circumference 1,169.45 feet. When I did it I used 372.24 feet.

Thom would have seen right away the coincidence with Stonehenge's diameter 1169 inches or 97.4522 feet / 2.75 = 35.437 or a lunar year. he and Aubrey Burl recognised the Moon working in many of the circles and the architect gave it to us in number. It is pretty difficult to create the circumference of a circle with a number suggesting a synodic month or lunar years if you cant find the diameter and for that you must use pi
