He also painted in Milan, for the Friars of S. Dominic, at S. Maria delle Grazie, a Last Supper, a most beautiful and marvellous thing; and to the heads of the Apostles he gave such majesty and beauty, that he left the head of Christ unfinished, not believing that he was able to give it that divine air which is essential to the image of Christ. This work, remaining thus all but finished, has ever been held by the Milanese in the greatest veneration, and also by strangers as well; for Leonardo imagined and succeeded in expressing that anxiety which had seized the Apostles in wishing to know who should betray their Master. For which reason in all their faces are seen love, fear, and wrath, or rather, sorrow, at not being able to understand the meaning of Christ; which thing excites no less marvel than the sight, in contrast to it, of obstinacy, hatred, and treachery in Judas; not to mention that every least part of the work displays an incredible diligence, seeing that even in the tablecloth the texture of the stuff is counterfeited in such a manner that linen itself could not seem more real. [Illustration: THE LAST SUPPER (_After the oil fresco by =Leonardo da Vinci=. Milan: S. Maria delle Grazie_) _M.S._] It is said that the Prior of that place kept pressing Leonardo, in a most importunate manner, to finish the work; for it seemed strange to him to see Leonardo sometimes stand half a day at a time, lost in contemplation, and he would have liked him to go on like the labourers hoeing in his garden, without ever stopping his brush. And not content with this, he complained of it to the Duke, and that so warmly, that he was constrained to send for Leonardo and delicately urged him to work, contriving nevertheless to show him that he was doing all this because of the importunity of the Prior. Leonardo, knowing that the intellect of that Prince was acute and discerning, was pleased to discourse at large with the Duke on the subject, a thing which he had never done with the Prior: and he reasoned much with him about art, and made him understand that men of lofty genius sometimes accomplish the most when they work the least, seeking out inventions with the mind, and forming those perfect ideas which the hands afterwards express and reproduce from the images already conceived in the brain. And he added that two heads were still wanting for him to paint; that of Christ, which he did not wish to seek on earth; and he could not think that it was possible to conceive in the imagination that beauty and heavenly grace which should be the mark of God incarnate. Next, there was wanting that of Judas, which was also troubling him, not thinking himself capable of imagining features that should represent the countenance of him who, after so many benefits received, had a mind so cruel as to resolve to betray his Lord, the Creator of the world. However, he would seek out a model for the latter; but if in the end he could not find a
