Last Supper (1498). Fresco. 460 x 880. The Last Supper is a late 15th-century mural painting by Italian artist Leonardo da Vinci housed by the refectory of the Convent of Santa Maria delle Grazie in Milan, Italy. It is one of the Western world's most recognizable paintings. The work is assumed to have been started around 1495-96 and was commissioned as part of a plan of renovations to the church and its convent buildings by Leonardo's patron Ludovico Sforza, Duke of Milan. The painting represents the scene of the Last Supper of Jesus with his apostles, as it is told in the Gospel of John, 13:21. Leonardo has depicted the consternation that occurred among the Twelve Apostles when Jesus announced that one of them would betray him. Due to the methods used, a variety of environmental factors, and intentional damage, only little of the original painting remains today despite numerous restoration attempts, the last being completed in 1999. The Last Supper measures 460 cm × 880 cm and covers an end wall of the dining hall at the monastery of Santa Maria delle Grazie in Milan, Italy. The theme was a traditional one for refectories, although the room was not a refectory at the time that Leonardo painted it. The main church building had only recently been completed, but was planned by Ludovico Sforza to be remodeled as a family mausoleum.The painting was commissioned by Sforza to be the centerpiece of the mausoleum. 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. 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. The apostles were identified by their names using a manuscript found in the 19th century. From left to right, according to the apostles' heads: Bartholomew, James, son of Alphaeus, and Andrew form a group of three; all are surprised. Judas Iscariot, Peter, and John form another group of three. Judas is wearing red, blue, and green and is in shadow, looking rather withdrawn and taken aback by the sudden revelation of his plan. He is clutching a small bag, perhaps signifying the silver given to him as payment to betray Jesus, or perhaps a reference to his role within the 12 disciples as treasurer. He is also tipping over the salt cellar. This may be related to the near-Eastern expression to betray the salt meaning to betray one's Master. He is the only person to have his elbow on the table and his head is also horizontally the lowest of anyone in the painting. Peter looks angry and is holding a knife pointed away from Christ, perhaps foreshadowing his violent reaction in Gethsemane during Jesus' arrest. He is leaning towards John and touching him on the shoulder, perhaps because in John's Gospel he signals the beloved disciple to ask Jesus who is to betray him. The youngest apostle, John, appears to swoon and lean towards Peter. There are also: Jesus. Apostle Thomas, James the Greater, and Philip are the next group of three. Thomas is clearly upset; the raised index finger foreshadows his incredulity of the Resurrection. James the Greater looks stunned, with his arms in the air. Meanwhile, Philip appears to be requesting some explanation. Matthew, Jude Thaddeus, and Simon the Zealot are the final group of three. Both Jude Thaddeus and Matthew are turned toward Simon, perhaps to find out if he has any answer to their initial questions. In common with other depictions of the Last Supper from this period, Leonardo seats the diners on one side of the table, so that none of them has his back to the viewer. Most previous depictions excluded Judas by placing him alone on the opposite side of the table from the other eleven disciples and Jesus, or placing halos around all the disciples except Judas. Leonardo instead has Judas lean back into shadow. Jesus is predicting that his betrayer will take the bread at the same time he does to Saints Thomas and James to his left, who react in horror as Jesus points with his left hand to a piece of bread before them. Distracted by the conversation between John and Peter, Judas reaches for a different piece of bread not noticing Jesus too stretching out with his right hand towards it.
