For the Dominican monks in Santa Maria delle Grazie in Milan he created a Last Supper of rare and marvelous excellence. He gave so much majesty and beauty to the heads of the apostles that he left the head of the Savior unfinished, convinced that he could not give it the heavenly divinity required for an image of Christ. The work remained as if it were finished and has always been praised by Milanese and foreigners alike. Leonardo had succeeded in expressing in the best way the suspicion that gripped the hearts of the apostles, who wanted to know who had betrayed their master. From the faces of all speaks love, fear and anger, but also the pain that they do not understand the soul of Christ, and this is just as wonderful as the defiance, hatred and betrayal that one recognizes in Judas, moreover, the slightest details of the whole work are worked with incredible care, even the fabric of the tablecloth is reproduced as one could not see it better in the finest linen.
It is said that the prior of the monastery very impetuously urged Leonardo to complete the work. It seemed strange to him to see the artist sometimes lost in contemplation for half a day. He would have preferred it if he, like workers who hoe the garden, had never laid down his brush. But this was not enough for him. He also complained to the duke and pressed him until the latter felt compelled to have Leonardo summoned and most kindly spurred him on to work, assuring him worthily that he was only doing so at the prior's importunity. Leonardo knew the clear mind and tact of the prince, so he decided to talk to him at length about the matter, which he would never have done with the prior. He spoke at length about art and made him understand that sublime minds sometimes create the most when they work the least, that is, when they invent and form perfect ideas, which the mind then grasps and the hands express and shape. Two heads, he added, were still missing: that of the Redeemer, for whom he did not want to search on earth and who, as he believed, could never come to his imagination in that beauty and heavenly grace which corresponded to the incarnate Godhead; the other, about which he was thinking, was that of Judas. It seemed impossible to him to find suitable features for that disciple whose defiant spirit, after so many benefits received, would have been capable of the decision to betray his Master, the Creator of the world. For this, however, he would seek, and if he found no other, he would still have the troublesome and meddlesome prior. This made the duke laugh very much, and he agreed with Leonardo a thousand times. The poor prior, however, being in confusion, occupied himself henceforth with his gardening and left the artist in peace; the latter finished the head of Judas so admirably that it is the true image of treachery and inhumanity; the head of Christ, on the other hand, remained unfinished.
The glory of this painting, the composition as well as the diligent execution aroused in the King of France the desire to have it brought into his kingdom. He searched in every way for builders who could bind it tightly enough with wooden beams and iron so that it could be taken away undamaged, he paid no attention to the possible costs, so great was his desire for it. However, because it was painted on the wall, his majesty finally lost the desire for it, and it remained in Milan.
Portrait of the Duke of Milan and Beatrice d'Este
While he was still working on the Last Supper, at the front of the same refectory where there is a Passion of Christ in the old style, he portrayed Duke Ludovico and his firstborn son Massmiliano, and to the other side the Duchess Beatrice with her younger son Francesco: Wonderful portraits.
