Archaeologists on Tuesday unearthed a skeleton in a rare state of preservation in Florence in what they believe may be a crucial step towards unravelling the mystery of the identity of the woman with the most enigmatic smile in the world. Several bodies have been discovered in the hunt to find the mortal remains of Lisa Gherardini, the Florentine noblewoman widely believed to have served as the muse for Leonardo da Vinci's "Mona Lisa".
