Final answer:
Leonardo da Vinci's 'The Last Supper' is predominantly interpreted as depicting the moment when Jesus reveals that there will be a betrayal by one of his apostles, leading to a range of emotional reactions among them.
Step-by-step explanation:
The painting often read as a depiction of the moment Jesus announces his impending betrayal during the Last Supper is Leonardo da Vinci's The Last Supper. In this groundbreaking work, Leonardo disrupts the traditional depiction by placing Judas on the same side of the table as Jesus and the other apostles. This causes the viewer to search for Judas among the figures, who are all reacting in various ways to the shocking news. The apostles are shown as being alarmed, upset, and inquisitive, representing a psychological depth that was unparalleled in prior renditions of the scene.
Referring to the Gospels, Leonardo's painting captures the tension of the dinner as Judas reaches for a plate at the same moment as Christ, foreshadowing the betrayal. Each apostle is identifiable by their attributes, and Judas is notably depicted holding a purse, symbolizing his acceptance of silver to betray Jesus. This painting is acclaimed for its masterful design and innovative approach to a traditional subject matter.
