Passage 6.7.2
οὗτοι μὲν ἀδελφοί τέ εἰσι καὶ Διαγόρου παῖδες, ἐπὶ δὲ αὐτοῖς κεῖται καὶ ὁ Διαγόρας, πυγμῆς ἐν ἀνδράσιν ἀνελόμενος νίκην· τοῦ Διαγόρου δὲ τὴν εἰκόνα Μεγαρεὺς εἰργάσατο Καλλικλῆς Θεοκόσμου τοῦ ποιήσαντος τὸ ἄγαλμα ἐν Μεγάροις τοῦ Διός. Διαγόρου δὲ καὶ οἱ τῶν θυγατέρων παῖδες πύξ τε ἤσκησαν καὶ ἔσχον Ὀλυμπικὰς νίκας, ἐν μὲν ἀνδράσιν Εὐκλῆς Καλλιάνακτός τε ὢν καὶ Καλλιπατείρας τῆς Διαγόρου, Πεισίροδος δὲ ἐν παισίν, ὃν ἡ μήτηρ ἀνδρὸς ἐπιθεμένη γυμναστοῦ σχῆμα ἐπὶ τῶν Ὀλυμπίων αὐτὴ τὸν ἀγῶνα ἤγαγεν·
These men are brothers, sons of Diagoras, and upon them stands Diagoras himself, who gained victory in boxing among men. The statue of Diagoras was made by Callicles the Megarian, son of Theocosmus, who also fashioned the statue of Zeus at Megara. The sons of Diagoras’ daughters also trained in boxing and achieved Olympic victories: Eucles, son of Callianax and Callipateira, daughter of Diagoras, among men; and Peisirodus among boys, whose mother herself accompanied him to Olympia disguised as a male trainer and attended the contest.
