When Donato di Nicolo di Betto Bardi, called Donatello because men loved his sweet and cheerful temper, died in 1466 at the age of eighty, the brightest light of Italian sculpture in its most promising period was extinguished. Donatello's influence, felt far and wide through Italy, was of inestimable value in correcting the false direction toward pictorial sculpture which Ghiberti, had he flourished alone at Florence, might have given to the art. His style was always eminently masculine. However tastes may differ about the positive merits of his several works, there can be no doubt that the principles of sincerity, truth to nature, and technical accuracy they illustrate, were all-important in an age that lent itself too readily to the caprices of the fancy and the puerilities of florid taste. To regret that Donatello lacked Ghiberti's exquisite sense of beauty, is tantamount to wishing that two of the greatest artists of the world had made one man between them. Donatello did not, in the strict sense of the term, found a school.[93] Andrea Verocchio, goldsmith, painter, and worker in bronze, was the most distinguished of his pupils. To all the arts he practised, Verocchio applied limited powers, a meagre manner, and a prosaic mind. Yet few men have exercised at a very critical moment a more decided influence. The mere fact that he numbered Lionardo da Vinci, Lorenzo di Credi, and Pietro Perugino among his scholars, proves the esteem of his contemporaries; and when we have observed that the type of face selected by Lionardo and transmitted to his followers, appears also in the pictures of Lorenzo di Credi and is first found in the "David" of Verocchio, we have a right to affirm that the master of these men was an artist of creative genius as well as a careful workman. Florence still points with pride to the "Incredulity of Thomas" on the eastern wall of Orsammichele, to the "Boy and Dolphin" in the court of the Palazzo Vecchio, and to the "David" of this sculptor: but the first is spoiled by heaviness and angularity of drapery; the second, though fanciful and marked by fluttering movement, is but a caprice; the third outdoes the hardest work of Donatello by its realism. Verocchio's "David," a lad of some seventeen years, has the lean, veined arms of a stone-hewer or gold-beater. As a faithful portrait of the first Florentine prentice who came to hand, this statue might have merit but for the awkward cuirass and kilt that partly drape the figure.
