Leda and the Swan is a tempera grassa on panel painting by an artist from the circle of Leonardo da Vinci, probably Cesare da Sesto. It dates to c. 1510-1520 and is now in the Galleria Borghese in Rome.[1] It and other versions at Wilton House and the Uffizi are considered the three best copies after Leonardo's own lost Leda and the Swan.[2]
