The contemporaries of Apelles were Protogenes, an excellent artist, whose merits his generous rival first pointed out. He was blamed for finishing too highly; yet, to obtain possession of one of his pictures, was the chief cause of the siege of Rhodes. Nicias, who is reported to have touched up the statues of Praxiteles--in what manner is not known, nor was Canova successful in his researches on this subject. Somewhat later lived Nichomachus, Pausius, Ætion, the Albano of antiquity, and others, with whom the art began to lapse. The causes and progress of this decline have already been traced in the history of sculpture. The remarks there are applicable to both arts, but peculiar circumstances rendered the progress of decay more rapid in painting. Even in the later contemporaries of the great ornament of the art, we discover a falling off from the great style, to one exactly resembling that of the modern Dutch school. Although the best pictures, from their greater rarity, were more highly valued in pecuniary estimation than statues, yet the art was never so completely national as Sculpture. The ambition was not cherished, nor the talents of painters directed, by the nationality of their performances; the general taste was not fixed by public and venerated monuments, consequently the wholesome restraints of public opinion operated but slightly, and were speedily withdrawn. Be it also remembered, that the standard here was formed after the severe purity of ancient taste, and morals had suffered sad relaxation. Hence painting was sooner abandoned to the caprice of private patronage and judgment; but the whole framework of her institutions, moral and political, was to be dissolved before sculpture,--which honored the forms of her religion; whose labours were publicly dedicated to the renown of her good, her learned, and her brave,--could cease to be regarded with national sympathy in Greece. Pausanias mentions the names of one hundred and sixtynine sculptors, and only fifteen painters; while, after three centuries of spoliation, he found in Greece three thousand statues, not one of them a copy, while he describes only one hundred and thirtyone paintings. The empire, then, of ancient painting, appears to have been of brief continuance, for, beyond the age now under review, no memorials of its greatness remain. The Romans prized this, as they have been shown to value every accomplishment in the fine arts, as ministering to luxury, and as a worthy employment for their slaves. In the early portion of their iron reign, Etruscan captives decorated their houses--subsequently itinerant Greeks; and though we find a few names of Roman painters, we never find it carried among them beyond mere embellishment. The moral dignity of the art never revived.
