Passage 9.35.6
ὅστις δὲ ἦν ἀνθρώπων ὁ γυμνὰς πρῶτος Χάριτας ἤτοι πλάσας ἢ γραφῇ μιμησάμενος, οὐχ οἷόν τε ἐγένετο πυθέσθαι με, ἐπεὶ τά γε ἀρχαιότερα ἐχούσας ἐσθῆτα οἵ τε πλάσται καὶ κατὰ ταὐτὰ ἐποίουν οἱ ζωγράφοι· καὶ Σμυρναίοις τοῦτο μὲν ἐν τῷ ἱερῷ τῶν Νεμέσεων ὑπὲρ τῶν ἀγαλμάτων χρυσοῦ Χάριτες ἀνάκεινται, τέχνη Βουπάλου , τοῦτο δέ σφισιν ἐν τῷ Ὠιδείῳ Χάριτός ἐστιν εἰκών, Ἀπελλοῦ γραφή, Περγαμηνοῖς δὲ ὡσαύτως ἐν τῷ Ἀττάλου θαλάμῳ, Βουπάλου καὶ αὗται·
But as for determining who among men first depicted the Graces naked, either sculpting them or representing them in painting, I have been unable to discover. In earlier works both sculptors and painters portrayed them clothed. At Smyrna there stand golden Graces, dedicated in the sanctuary of the Nemeses, placed above the statues, the work of Boupalos; and also at Smyrna in the Odeion there is a painting of the Graces by Apelles. Likewise, the Pergamenes have in the chamber of Attalos figures of the Graces, these also by Boupalos.
