Mrs Hamhead spotted both...and that was without her galsses on and with only half a glass of red wine drunk! She said it looked like a cloaked figure at the front.
I could see them to..but I though it looked like a figure leaning from the right whilst the other figure was behind.
Romance of the Stones says "a tall hooded woman, a Madonna like statue, a version of Michaelangelo's Awakening Giant in quartz".
