He never put his thoughts into words, and probably never admitted even to himself that the works he had most admired were lacking in beauty; he merely asserted that the statues of the old Romans and Greeks were astonishingly beautiful. In reality, however, he was perpetually comparing the two, and always to the disadvantage of the moderns. It is possible in our day to judge justly the comparative merits of antique sculpture and of that of the early Renaissance; or rather to appreciate them as two separate sorts of art, delightful in quite different ways, letting ourselves be charmed not more by the actual beauty of form, and nobility of movement of the one than by the simplicity, the very homeliness, the essentially human quality of the other. To us there is something delightful in the very fact that the Davids of Donatello and Verrocchio are mere ordinary striplings from the street and the workshop, that the singers of Luca della Robbia are simple unfledged choir-boys, and the Virgins of Mino Florentine fine ladies; we have enough of antique perfection, we have had too much of pseudo-antique faultlessness, and we feel refreshed by this unconsciousness of beauty and ugliness. A contemporary could not enter into such feelings, he could not enjoy his own and his fellows' _naïveté_; besides, the antique was only just becoming manifest, and therefore triumphant. To Domenico, Donatello's David became more and more unsatisfactory, faulty above the waist, positively ungainly below, weak and lubberly; how could so divine an artist have been satisfied with that flat back, those narrow shoulders and thick thighs? He felt freer to dislike the work of Verrocchio, his own teacher, and a man without Donatello's overwhelming genius; that David of his, with his immense head and wizen face, his pitiful child's arms and projecting clavicles, straddling with hand on hip; was it possible that a great hero, the slayer of a giant (Domenico's notions of giants were taken rather from the romances of chivalry recited in the market than from study of Scripture) should have been made like that? And so, like his great contemporary Mantegna in far-off Lombardy, Domenico turned that eager curiosity with which he had previously sought for the secret of flayed limbs and fleshless skeletons, to studying the mystery of proportion and beauty which was hidden, more subtly and hopelessly, in the broken marbles of the Pagans.
