In addition to the Hermes, we have direct literary evidence as to a great group of Artemis and Apollo, the work of Praxiteles, at Mantinea. We are told also the subject of certain reliefs on the architectural base of it, and reliefs of very fine workmanship corresponding in subject have been excavated at Mantinea. There is thus a very fair presumption that these panels were designed, if not executed, by the master who made the group. One slab, here illustrated,[85] shows the contest between Apollo the harper and Marsyas the semi-bestial player of that barbarous instrument the flute. Marsyas had challenged Apollo to a contest, and being quite inevitably defeated was flayed alive as a punishment for his presumption. The penalty is delicately indicated by the Phrygian slave who holds the knife in the centre. The fourth-century artists seldom missed a psychological point, and Praxiteles has emphasised the contrast between the dignified god in his majestic harper’s robes [Illustration: PLATE LXXI. FIGURE OF A YOUTH: FROM CERIGO _English Photo Co., Athens_] and the naked, violent Satyr distending his cheeks as flute-playing barbarians were not ashamed to do. It is evident that the Marsyas is a quotation by Praxiteles of the celebrated figure by Myron. We note, as a technical point in the history of relief sculpture, the effect produced by the wide spacing of the figures. On the other slabs are beautiful though mutilated figures of the Muses, who acted as umpires in the contest.
