The Last Supper is Leonardo's visual interpretation of an event chronicled in all the four Gospels of the New Testament. The evening before Christ was betrayed by one of his disciples, he gathered them together to eat, told them he knew what was coming and washed their feet (a gesture symbolizing that all were equal under the eyes of the Lord). As they ate and drank together, Christ gave the disciples explicit instructions on how to eat and drink in the future, in remembrance of him. It was the first celebration of the Eucharist.
