Researchers told journalists at a news conference in Florence Thursday that testing found one of three pieces of remains compatible with the period in which Lisa Gherardini died, and that historical documents indicate she was buried in a Florence convent in 1542.
Head researcher Silvano Vinceti says there are few remains and no skull, which might have helped determine if the woman could have been Leonardo's model for the portrait now in the Louvre museum in Paris.
Art historians differ on who might have been the enigmatically smiling model. Some say he used a male model.
