Leonardo lived in Milan from 1482 to until 1499 working mainly at the court of Duke Ludovico Sforza (Il Moro). His paintings in the 1480s included portraits, notably the marvellous picture of Duke Ludovico's mistress Cecilia Gallerani known as the Lady with an Ermine and an altarpiece of the Virgin of the Rocks, which exists in two problematically related versions, the earlier (Louvre, Paris) possibly painted when Leonardo still was in Florence, the later (National Gallery, London) still being worked on in 1508.
