Which moment from the Gospels does Leonardo da Vinci’s Last Supper show?

Leonardo da Vinci’s Last Supper does not depict a single frozen moment; rather, it represents a sequence of closely connected events described in the Gospels.1

The painting primarily captures the dramatic moment when Jesus declares to his Apostles that one of them will betray him. Simultaneously, the work illustrates the institution of the Eucharist, as Jesus gestures toward a glass of wine and a piece of bread.213

Leonardo used these events to create a complex study of human psychology, showing the varied emotional reactions of the 12 disciples as they process the announcement of the betrayal. For instance, the scene captures the specific interaction where Jesus and Judas reach toward the same dish, identifying Judas as the betrayer, while other disciples react with gestures of disbelief, anger, or grief.21
