In the composition of The Last Supper, the author first sets the scene, and then arranges the characters from the perspective of the scene. The author's perspective of the scene is very rigorous, achieving a perfect spatial expression. For example, the final focus of the perspective of the table and room in the scene is on the right eye of the protagonist. This rigor requires a lot of knowledge.

The Last Supper was created by Italian artist Leonardo da Vinci, with the theme of the last supper between Jesus and the twelve disciples in the Bible.

The expressions of panic, anger, doubt and remorse, as well as gestures, eyes and behaviors of the characters in the picture are vividly portrayed, which is the most famous of all works created on this theme. Collected in Santa Maria Thanksgiving Church in Milan, Italy.

Extended data:

To paint The Last Supper, we must first evenly coat the wall of the monastery dining room with plaster. The plaster in the middle of the wall is rougher than the plaster next to it, because it can be more firmly attached to the paint layer covering it.

People found the sketch trace of The Last Supper, which was painted directly on plaster. "A very simple red line is drawn with a smooth brush, and the outline or shape of everyone is outlined according to his layout."
