This is a photograph of Leonardo da Vinci’s painting of the same name.

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. DaVinci places Jesus as the triangular focal point in this piece, flanked by His disciples, framed by the doorway behind Him and with all the lines of perspective in the ceiling and walls radiating out from His head. 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.
