Why is the painting The Last Supper called The Last Supper?

It means: these people ate together for the last time, and they won't have such an opportunity again. It means that Judas has betrayed Jesus at this time, and Jesus will be arrested after this meal.

The allusion comes from Leonardo da Vinci's painting The Last Supper, which is based on religious stories. Jesus was betrayed by Judas, one of his disciples, and had the last supper with all his disciples. The characters in the painting all have different expressions after hearing that Jesus was betrayed, which can be seen by Leonardo da Vinci's painters. Nowadays, many people use this sentence differently, which can express that from now on, the good days are over, the hard days are coming, or trouble is coming.

What did the last dinner say?

Leonardo da vinci's The Last Supper takes the conflict between Jesus and Judas in the Bible as the background, showing the contest between human justice and evil, showing a specific humanistic theme and carrying forward the humanistic spirit of the times. Leonardo da vinci profoundly reproduces the sharpness of this struggle through the psychological description of characters and the description of drama scenes. When Jesus said that someone betrayed him, the twelve disciples showed various expressions and actions: surprise, anger, cursing and nervousness, especially Judas' behavior, which was vividly portrayed. The whole picture, the change of mood, the expression of personality, the tendency of action and the combination of characters are obviously dramatic and conflicting, which is a good metaphor for the struggle between light and darkness, beauty and evil.
