The document summarizes Leonardo da Vinci's famous painting "The Last Supper". It describes the painting's massive size (15x29 feet), location in a refectory in Milan, Italy, and depiction of Jesus and his disciples at the Last Supper. The composition directs the viewer's eye to Jesus and uses perspective techniques. The painting took Leonardo 3 years to complete from 1495-1498. It is now deteriorating due to Leonardo experimenting with an unstable fresco technique using dry plaster instead of the traditional wet plaster method.
