The people who accomplished these great monuments seem to have thought only in terms of the universe. They did not seek for the embodiment of goodness, nobility, and charity, perfection in which qualities we regard as divine, but they aimed at a majesty which included all these things; which comprehended nothing but the supreme in form and mind; and with an all-reaching knowledge of the human race, stood outside of it, but covered it with reflected glory, as the sun stands ever away from the planets but illumines them all. The wonder is not that these ideals were created in the minds of the Greeks, for there is no boundary to the imagination, but that minds could be found to set them down in design, and hands to mould and shape them in clay and stone; and that many minds and hands could do these things in the same epoch. That these sculptured forms have never been equalled is not wonderful; that they never will be surpassed is as certain as that death is the penalty of life. So firmly have they become grafted into the minds of men as things unapproachable in beauty, that they have themselves been converted into general ideals towards which all must climb who attempt to scale the heights of art. The greatest artists known to us since the light of Greek intelligence flickered away, have been content to study these marble remains, and to cull from them a suggestion here, and an idea there, with which to adorn their own creations. Indeed it is clear that from the time of Niccolo Pisano, who leaped at one bound to celebrity after studying the antique sculptures at Pisa, through Giotto to the fifteenth and sixteenth century giants, there was hardly a great artist who was not more or less dependent upon Grecian art for his skill, and the most enduring of them all--Donatello, Raphael, Michelangelo, Titian, Correggio--were the most deeply versed in the art.[42]
Bellori affirmed that the Roman school, of which Raphael and Michelangelo were the greatest masters, derived its principles from the study of the statues and other works of the ancients.[a] This is not strictly exact, but it is near the truth, and certain it is that Michelangelo, the first sculptor known to the world since the Dark Age, willingly bowed his head before the ancient triumphs of art presented to his view. And yet he did not see the Parthenon sculptures and other numerous works of the time of Phidias, with the many beautiful examples of the next century which have been made available since his day. What he would have said in the presence of the glories of the Parthenon, with the Hermes of Praxiteles and the rest of the collection from Olympia, is hard to conjecture, though it may well be suggested that they would have prompted him to still higher work than any he accomplished. With these stupendous ideals in front of us, it seems almost unnecessary to talk of the principles of art. Their very perfection indicates that they were built up on eternal principles, so that in fact and in theory they form the surest guide for the sculptor and painter.
