Some scholars say the painting was a self-portrait of a disguised Leonardo da Vinci, while others say it is clearly Leo's mom. Many others believe Mona is Lisa Gherardini, the wife of a wealthy Florentine silk merchant.

Vincetti, who has noted the similarity between those works and the Mona Lisa, particularly in the depiction of mouths and noses, claims they are all definitely Caprotti mouths and noses, and says, “Salai was a favourite model for Leonardo, [who] certainly inserted characteristics of Salai in the ... Mona Lisa.”
Which leads Vincetti to also claim that Salai was "probably Leonardo’s lover.” Vincetti adds that Salai often stole from DaVinci, but he was always forgiven.
So, is Mona a man? If if she, er, he is, was he Leo's lover?
Only that smile knows for certain.
