Without being so original or so attractive an artist as Botticelli, his contemporary, Ghirlandajo, was a stronger one. His strength came more from assimilation than from invention. He combined in his work all the art learning of his time. He drew well, handled drapery simply and beautifully, was a good composer, and, for Florence, a good colorist. In addition, his temperament was robust, his style dignified, even grand, and his execution wonderfully free. He was the most important of the fifteenth-century technicians, without having any peculiar distinction or originality, and in spite of being rather prosaic at times. [Illustration: FIG. 29.--FRANCESCA. DUKE OF URBINO. UFFIZI.] Verrocchio (1435-1488) was more of a sculptor than a painter, but in his studio were three celebrated pupils--Perugino, Leonardo da Vinci, and Lorenzo di Credi--who were half-way between the Early and the High Renaissance. Only one of them, Leonardo, can be classed among the High Renaissance men. Perugino belongs to the Umbrian school, and Lorenzo di Credi (1450-1537), though Florentine, never outgrew the fifteenth century. He was a pure painter, with much feeling, but weak at times. His drawing was good, but his painting lacked force, and he was too pallid in flesh color. There is much detail, study, and considerable grace about his work, but little of strength. Piero di Cosimo (1462-1521) was fond of mythological and classical studies, was somewhat fantastic in composition, pleasant in color, and rather distinguished in landscape backgrounds. His work strikes one as eccentric, and eccentricity was the strong characteristic of the man.
