Mona Lisa was depicted between 1503 and 1504; yet, the debates around her identity and the commissioning of the painting are still open.
According to the most plausible hypothesis, the woman could be Monna Lisa Gherardini, born in Florence in May 1479 and the buyer could be Francesco del Giocondo, her husband. The Gherardini family owned lands in Panzano in Chianti and San Donato in Poggio as well as a villa in Vignamaggio.
However, other studies make us believe that she is Isabella Gualanda, a Florentine maiden, lover of Giuliano de 'Medici. A little curiosity: Isabella, born from the Pisan Ranieri Gualandi and Bianca Gallerani, was probably the cousin of Cecilia, portrayed by Leonardo in the Lady with an ermine.
