tool which is at fault in those constrained, simpering warriors of the schools of Ægina, in those slim-waisted dæmonic dancers of the Apulian vases; the eye is as familiar with the human body, the mind as accustomed to select its beauty from its ugliness, as the eye and mind of such of us as cannot paint are familiar nowadays with the shapes and colours, with the charm of the trees and meadows that we love. The contemporaries, on the contrary, of Donatello had received from the sculptors of the very farthest Middle Ages, those who carved the magnificent patterns of Byzantine coffins and the exquisite leafage of Longobard churches, a remarkable mastery over the technical part of their craft. The hand was cunning, but the eye unfamiliar. Hence it comes that the sculpture of the earlier Renaissance displays perfection of workmanship, which occasionally blinds us to its poverty of form, and even to its deficiency of science. And hence also the rapidity with which every additional item of knowledge is put into practice that seems to argue perfect familiarity. But these men were not really familiar with their work. The dullest modern student, brought up among casts and manuals, would not be guilty of the actual anatomical mistakes committed every now and then by these great anatomists, so passionately curious of internal structure, so exquisitely faithful to minute peculiarity, let alone the bunglings of men so certain of their pencil, so exquisitely keen to form, as Botticelli. As a matter of fact, every statue or drawn figure of this period represents a hard fight with ignorance and with unfamiliarity worse than ignorance. The grosser the failure hard-by, the more splendid the real achievement. For every limb modelled truthfully from the life, every gesture rendered correctly, every bone or muscle making itself felt under the skin, every crease or lump in the surface, is so much conquered from the unknown. So long as this study, or rather this ignorance, continued, the antique could be appreciated only very partially, and almost exclusively in the points in which it differed least from the works of these modern men. It must have struck them by its unerring science, its great truthfulness to nature, but its superior beauty could not have appealed to artists too unfamiliar with form to think of selecting it. The study of antique proportion, the reproduction of antique types, so visible in the sculptures of Michelangelo, of Cellini, and of Sansovino, and no less in the painting of Raphael, of Andrea, and even of the later Venetians, was very unimportant in the school of Donatello; and it is probable that he and his pupils did not even perceive the difference between their own works and the old marbles, which they studied merely as so many realistic documents.
