Ludovico Maria Sforza (also known as Ludovico il Moro;[1] 27 July 1452 – 27 May 1508), was Duke of Milan from 1494, following the death of his nephew Gian Galeazzo Sforza, until 1499. A member of the Sforza family, he was the fourth son of Francesco I Sforza. He was famed as a patron of Leonardo da Vinci and other artists, and presided over the final and most productive stage of the Milanese Renaissance. He is probably best known as the man who commissioned The Last Supper.
