Interesting article. I am related to Sir William Harvey, physicion to James and Charles 1st. In my research I found that he visited the Henge to investigate the stones. I was never clear on why. However, I believe that if the idea of the Henge existing for healing is correct then this may explain Williams interest.
I know that he explored a number of places of "magical" power on behalf of the king his queen and children.
