Raphael was gentle, affectionate, sympathetic, intense, lovable; Michael Angelo was tender at heart but austere in manner, doing only great works, and thinking great thoughts. "Raphael," says Grimm, "had one excellence, which, perhaps, as long as the world stands, no other artist has possessed to such an extent,--his works suit more closely the average human mind. There is no line drawn above or below. Michael Angelo's ideals belong to a nobler, stronger generation, as if he had had demigods in his mind, just as Schiller's poetical forms, in another manner, often outstep the measure of the ordinary mortal.... Leonardo sought for the fantastic, Michael Angelo for the difficult and the great; both labored with intense accuracy, both went their own ways, and impressed the stamp of nature on their works. Raphael proceeded quietly, often advancing in the completion only to a certain point, at which he rested, apparently not jealous at being confounded with others. He paints at first in the fashion of Perugino, and his portraits are in the delicate manner of Leonardo: a certain grace is almost the only characteristic of his works. At length he finds himself in Rome, opposed alone to Michael Angelo; then only does the true source of power burst out within him; and he produces works which stand so high above all his former ones that the air of Rome which he breathed seemed to have worked wonders in him.... Raphael served the court with agreeable obsequiousness; but under the outward veil of this subservient friendliness there dwelt a keen and royal mind, which bent before no power, and went its own way solitarily, like the soul of Michael Angelo." The Sistine Chapel was finished, probably, in 1512, and Michael Angelo returned with ardor to the Julius monument, which, however, had been reduced in plan from the original. He worked on the central figure, Moses, with great joy, believing it would be his masterpiece. "This statue," says Charles Christopher Black of Trinity College, Cambridge, "takes rank with the Prometheus of Æschylus, with the highest and noblest conceptions of Dante and Shakespeare." "He sits there," says Grimm, "as if on the point of starting up, his head proudly raised; his hand, under the arm of which rest the tables of the law, is thrust in his beard, which falls in heavy, waving locks on his breast; his nostrils are wide and expanding, and his mouth looks as if the words were trembling on his lips. Such a man could well subdue a rebellious people, drawing them after him, like a moving magnet, through the wilderness and through the sea itself. "What need we information, letters, supposititious records, respecting Michael Angelo, when we possess such a work, every line of which is a transcript of his mind?"
