"While the best and most industrious artists," says Vasari, "were labouring by the light of Giotto and his followers to give the world examples of such power as the benignity of their stars and the varied character of their fantasies enabled them to command, and while desirous of imitating the perfection of Nature by the excellence of Art, they were struggling to attain that high comprehension which many call intelligence, and were universally toiling, but for the most part in vain, the Ruler of Heaven was pleased to turn the eyes of his clemency towards earth, and perceiving the fruitlessness of so many labours, the ardent studies pursued without any result, and the presumptuous self-sufficiency of men which is farther from truth than is darkness from light, he resolved, by way of delivering us from such great errors, to send to the world a spirit endowed with universality of power in each art, and in every profession, one capable of showing by himself alone what is the perfection of art in the sketch, the outline, the shadows, or the lights; one who could give relief to painting and with an upright judgment could operate as perfectly in sculpture; nay, who was so highly accomplished in architecture also, that he was able to render our habitations secure and commodious, healthy and cheerful, well-proportioned, and enriched with the varied ornaments of art." A more prosaic passage follows presently, occasioned by the innuendoes of Condivi as to Vasari's intimacy with Michelangelo and his knowledge of the facts of his life at first hand. Vasari meets this accusation by quoting the following document relating to the apprenticeship of Michelangelo to Domenico Ghirlandaio when fourteen years old. "1488. I acknowledge and record this first day of April that I, Lodovico di Buonarroti, have engaged Michelangelo my son to Domenico and David di Tommaso di Currado for the three years next to come, under the following conditions: That the said Michelangelo shall remain with the above named all the said time, to the end that they may teach him to paint and to exercise their vocation, and that the above named shall have full command over him paying him in the course of these three years twenty-four florins as wages...."
