There is a chronicle documentary about him,
He says something like this talking about the design of the circles.
The man in the street, now he had no idea what was in these things, but the people who designed them, the priests if you like, they knew.
So the designs were possibly secret, or Thom seemed to think so.
i recommend watching between minutes 11 to 16 first
