The Last Supper (Italian: Il Cenacolo or L'Ultima Cena) is a 15th century mural painting in Milan created by Leonardo da Vinci for his patron Duke Ludovico Sforza and his duchess Beatrice d'Este. It represents the scene of The Last Supper from the final days of Jesus as narrated in the Gospel of John 13:21, when Jesus announces that one of his Twelve Apostles would betray him. The Last Supper measures 460 × 880 centimeters (15 feet × 29 ft) and covers the back wall of the dining hall at Santa Maria delle Grazie in Milan, Italy.
The theme was a traditional one for refectories, but Leonardo's interpretation gave it much greater realism and depth. The lunettes above the main painting, formed by the triple arched ceiling of the refectory, are painted with Sforza coats-of-arms. The opposite wall of the refectory is covered by the Crucifixion fresco by Giovanni Donato da Montorfano, to which Leonardo added figures of the Sforza family in tempera.
(These figures have deteriorated in much the same way as has The Last Supper.) Leonardo began work on The Last Supper in 1495 and completed it in 1498—however, he did not work on the piece continuously throughout this period. This beginning date is not certain, as "the archives of the convent have been destroyed and our meagre documents date from 1497 when the painting was nearly finished." The Last Supper specifically portrays the reaction given by each apostle when Jesus said one of them would betray him. All twelve apostles have different reactions to the news, with various degrees of anger and shock.
