The Duke was interested in statues and pictures—what he called "results"—he didn't care for speculations or theories, and only a live horse that could run fast interested him. So to keep the peace, the gracious Leonardo painted portraits of the Duke's mistress, posing her as the Blessed Virgin, thus winning the royal favor and getting carte-blanche orders on the Keeper of the Exchequer. As a result of this Milan period we have the superb portrait, now in the Louvre, of Lucrezia Crivelli, who was supposed to be the favorite of the Duke.

But the Duke was a married man, and the good wife must be placated. She had turned to religion when her lover's love grew cold, just as women always do; and for her Leonardo painted the "Last Supper" in the dining-room of the monastery which was under her especial protection, and where she often dined.

The devout lady found much satisfaction in directing the work, which was to be rather general and simply decorative. But the heart of Leonardo warmed to the task and as he worked he planned the most famous painting in the world. All this time Leonardo had many pupils in painting and sculpture. Soon he founded the Milan Academy of Art. At odd times he made designs for the Duke's workers in silver and gold, drew patterns for the nuns to embroider from, and gave them and the assembled ladies, invited on the order of the Duke's wife, lessons in literature and the gentle art of writing poetry.

The Prior of the monastery watched the work of the "Last Supper" with impatient eyes. He had given up the room to the lumbering scaffolds, hoping to have all cleaned up and tidy in a month, come Michaelmas. But the month had passed and only blotches of color and black, curious outlines marred the walls. Once the Prior threatened to remove the lumber by force and wipe the walls clean, but Leonardo looked at him and he retreated.

Now he complained to the Duke about the slowness of the task. Leonardo worked alone, allowing no pupil or helper to touch the picture. Five good, lively men could do the job in a week—"I could do it myself, if allowed," the good Prior said. Often Leonardo would stand with folded arms and survey the work for an hour at a time and not lift a brush; the Prior had seen it all through the keyhole!

The Duke listened patiently and then summoned Leonardo. The painter's gracious speech soon convinced the Duke that men of genius do not work like hired laborers. This painting was to be a masterpiece, fit monument to a wise and virtuous ruler. So consummate a performance must not be hastened; besides there was no one to pose for either the head of Christ or of Judas. The Christ must be ideal and the face could only be conjured forth from the painter's own soul, in moments of inspiration. As for Judas, "Why, if nothing better can be found—and I doubt it much—I believe I will take as model for Judas our friend the Prior!" And Leonardo turned to the Prior, who fled and never again showed his face in the room until the picture was finished.

The Prior's complaint, that Leonardo had too many irons in the fire, was the universal cry the groundlings raised against him. "He begins things, but never completes them," they said.

The man of genius conceives things; the man of talent carries them forward to completion. This the critics did not know. It is too much to expect the equal balance of genius and talent in one individual. Leonardo had great talent, but his genius outstripped it, for he planned what twenty lifetimes could not complete. He was indeed the endless experimenter—his was in very truth the Experimental Life. His incentive was self-development—to conceive was enough—common men could complete. To try many things means Power: to finish a few is Immortality.

God's masterpiece is the human face. A woman's smile may have in it more sublimity than a sunset; more pathos than a battle-scarred landscape; more warmth than the sun's bright ray; more love than words can say.

The human face is the masterpiece of God.
