Couldn’t the mystery of Anne Boleyn’s appearance be solved by studying her facial features from the paintings that are said to portrait her and by comparing those to her facial skeleton? I saw this documentary where they did the same thing to some Queen of Egypt.
The only contemporary image we have of Anne is the 1534 medal. None of the portraits we have of her are contemporary and we don't know for certain that the remains thought to be of Anne are actually Anne. I think she will always remain a mystery, unless another portrait comes to light.
