its rise and decline were the outcome of simple matter-of-fact conditions of a more or less accidental nature, uninfluenced by an æsthetic impulse in the sense of inspiration. The most common suggestion advanced to account for the rise in Grecian art, is that it was due to the exaltation of the Greek mind through the victories of Marathon, Platæa, and Salamis. That a people should be so trampled upon as were the Greeks; that their cities should be razed, their country desolated, and their commerce destroyed; that notwithstanding all this they should refuse to give way before enemies outnumbering them twenty, fifty, or even a hundred to one; and that after all they should crush these enemies, was no doubt a great and heroic triumph, likely to exalt the nation and feed the imagination of the people for a long time to come; but that these victories were responsible for the lofty eminence reached by the Greek artists, cannot be maintained. From what we know of Calamis, Myron, and others, it is clear that Grecian art was already on its way to the summit reached by Phidias when Marathon and Salamis were fought, though the victories of the Greek arms hastened the development for the plain reason that they led to an increased demand for works of art. And the decline in Grecian art resulted purely and simply from a lessened demand. Though this was the reason for the general decay, there was a special cause for the apparent weakening with the commencement of the fourth century B.C. In the fifth century Phidias climbed as high in the accomplishment of ideals as the imagination could soar. He reached the summit of human endeavour. Necessarily then, unless another Phidias arose, whatever in art came after him would appear to mark a decline. But it is scarcely proper to put the case of Phidias forward for comparative purposes. He carried the art of sculpture higher than it is possible for the painter to ascend, and so we should rather use the giants of the fourth century--Scopas, Praxiteles, Lysippus, Apelles--as the standards to be compared with the foremost spirits of the Italian Renaissance--Raphael and Michelangelo--for each of these groups achieved the human ideal, though failing with the spiritual ideal established by Phidias.
