Accordingly, since only victors who had won three or more contests at Olympia could set up iconic statues, the great majority of statues there represented some ideal type of common applicability, in which there was no attempt to show the individual features of this or that victor, but rather the typical athlete of muscular build. The older statues were merely variations of a few types which were held to be appropriate to the purpose. In process of time these few types in their treatment of details gradually approached truth to nature; this was especially characteristic of the Peloponnesian schools, which adopted the _Doryphoros_ of Polykleitos as their norm of proportions. Statues of victors were the stock subject of the closely related schools of Argos and Sikyon.[533] Doubtless, as E. A. Gardner says,[534] there existed at Olympia itself a school of subordinate artists, who filled the regular demand for victor statues. However, some of these statues, especially those of the fifth and fourth centuries B. C., as we see them in originals and in Roman copies, and read the æsthetic judgments of them in Greek writers, were real works of art. ÆSTHETIC JUDGMENTS OF CLASSICAL WRITERS. The literary evidence for Greek sculpture is, for the most part, very unsatisfactory. Though classical writers were uncritical and not fond of analysis, still they have left us some useful opinions about works of sculpture and painting. The history and criticism of sculpture began in Greece, in the fourth century B. C., with the Peripatetics. Aristotle, whose observations on painting and sculpture were slight, did not despise the “mimetic” arts as did the Socrates of Plato.[535] In the _Rhetoric_[536] he speaks of the beautiful bodies of youths who trained as pentathletes, since the varied exercises of the pentathlon made them so. We have a similar opinion expressed by Xenophon in what is, perhaps, the most interesting passage in Greek literature on criticism of art.[537] He has Sokrates go to the sculptor Kleito and compliment him on his power of representing different physical types produced by various contests, noting differences between statues of runners and wrestlers and between those of boxers and pancratiasts. When asked how he makes statues lifelike, Kleito has no answer, and the philosopher says it is by the imitation of real men, _i. e._, nature. He adds: “Must you not then imitate the threatening eyes of those who are fighting and the triumphant expression of those who are victorious?” Though some have thought that these words refer to portrait statues, which were spoken of as a matter of course at the beginning of the fourth century B. C., it is more reasonable to suspect that Sokrates was speaking of the older sculptors—for we may recognize Polykleitos in Kleito[538]—and consequently that he is not referring to portraiture. In the _Symposium_ of Xenophon[539] Sokrates also complains that the long-distance runners (δολιχοδρόμοι) have thick
