Leonardo’s Last Supper (1495–98) is among the most famous paintings in the world. In its monumental simplicity, the composition of the scene is masterful; the power of its effect comes from the striking contrast in the attitudes of the 12 disciples as counterposed to Christ. Leonardo portrayed a moment of high tension when, surrounded by the Apostles as they share Passover, Jesus says, “One of you will betray me.” All the Apostles—as human beings who do not understand what is about to occur—are agitated, whereas Christ alone, conscious of his divine mission, sits in lonely, transfigured serenity. Only one other being shares the secret knowledge: Judas, who is both part of and yet excluded from the movement of his companions. In this isolation he becomes the second lonely figure—the guilty one—of the company.
In the profound conception of his theme, in the perfect yet seemingly simple arrangement of the individuals, in the temperaments of the Apostles highlighted by gesture, facial expressions, and poses, in the drama and at the same time the sublimity of the treatment, Leonardo attained a height of expression that has remained a model of its kind. Countless painters in succeeding generations, among them great masters such as Rubens and Rembrandt, marveled at Leonardo’s composition and were influenced by it and by the painting’s narrative quality. The work also inspired some of Goethe’s finest pages of descriptive prose. It has become widely known through countless reproductions and prints, the most important being that produced by Raffaello Morghen in 1800. Thus, The Last Supper has become part of humanity’s common heritage and remains today one of the world’s outstanding paintings.
Technical deficiencies in the execution of the work have not lessened its fame. Leonardo was uncertain about the technique he should use. He bypassed traditionalfresco painting, which, because it is executed on fresh plaster, demands quick and uninterrupted painting, in favour of another technique he had developed: temperaon a base, which he mixed himself, on the stone wall. This procedure proved unsuccessful, inasmuch as the base soon began to loosen from the wall. Damage appeared by the beginning of the 16th century, and deterioration soon set in. By the middle of the century, the work was called a ruin. Later, inadequate attempts at restoration only aggravated the situation, and not until the most-modern restoration techniques were applied after World War II was the process of decay halted. A major restoration campaign begun in 1980 and completed in 1999 restored the work to brilliance but also revealed that very little of the original paint remains.
