Isabella, Duchess of Naples, Aragon, and Bari. 1470-1524 ... She is also Leonardo DaVinci's "Mona Lisa" The painting on the left is a not-well-known copy located in Italy. It is my favorite version besides the Louvre version. She looks younger in this version. The painting on the right is 'Salome with the Head of John the Baptist' by Bernardino Luini. Here we see the same face as the Louvre painting and the painting on the left . She is the rightful Duchess of Milan & Bari.
