Sforza Family portraits in Santa Maria delle Grazie by Leonardo da Vinci

The Portraits of the Dukes of Milan with their sons are a series of oil and tempera paintings on plaster (90 cm base each) by Leonardo da Vinci, datable to 1497 and preserved on the sides of the Crucifixion by Donato Montorfano in the former refectory of the convent of Santa Maria delle Grazie. The works, confirmed by ancient sources, are now poorly readable.
