I guess this is what you read
"“Fronting the gate of Botalac town place”, writes Borlase, “there is a most remarkable miz maze, if I may so term it, of stones set on end, which if Ducaleon himself had thrown behind his back could not sufficiently stood up in greater disorder than they at present appear, but viewing them diligently this March 6th, 1737, I find the largest circle monument there of any I yet have met with, with several subordinate circles, some touching the circumferences, some breaking within it; together with two large erected stones, not many paces from the principal ring.”"

so even his description admits it's a right muddle - so he's seeing circles where there weren't any? (ah the bind of the enthusiastic antiquarian, I'm sure we've all been there?)
