Mona Lisa, forever protected behind bullet proof glass at the Louvre, was modeled not after Lisa Gherardini, the wife of a wealthy Florentine silk merchant, but Leonardo da Vinci’s “companion” Gian Giacomo Caprotti, art scholars are claiming. Caprotti joined the artist’s side around age 10, in 1490, and his slim fem appearance and curly hair were the basis of the Mona Lisa, as well as two paintings of St John the Baptist and the drawing “Angel Incarnate,” insists Silvano Vinceti of the National Committee for the Preservation of Cultural Heritage. “Salai was a favourite model for Leonardo,” says Vinceti. “Leonardo certainly inserted characteristics of Salai in the … Mona Lisa. … Salai was very handsome and probably Leonardo’s lover. He stole from Leonardo and caused him many problems, but the artist always forgave him.” Not that all art historians are in agreement, of course. But like any other gender-defying person. Ms. Mona Lisa is subject to unprovoked attacks.
