Passage 6.9.2
μετὰ δὲ τὴν εἰκόνα τοῦ ἀνδρὸς ὃν Ἠλεῖοί φασιν οὐ γραφῆναι μετὰ τῶν ἄλλων, ὅτι ἐπὶ κάλπης ἀνηγορεύθη δρόμῳ, μετὰ τούτου τὴν εἰκόνα Ξενοκλῆς τε Μαινάλιος ἕστηκε παλαιστὰς καταβαλὼν παῖδας καὶ Ἄλκετος Ἀλκίνου κρατήσας πυγμῇ παῖδας, Ἀρκὰς καὶ οὗτος ἐκ Κλείτορος· καὶ τοῦ μὲν Κλέων , Ξενοκλέους δὲ τὸν ἀνδριάντα Πολύκλειτός ἐστιν εἰργασμένος.
Next to the statue of the man whom the Eleans claim was not recorded alongside the others because he was proclaimed as victor in the foot-race by drawing lots after a tied result, stands the image of Xenokles of Mainalos, who defeated his competitors in boys' wrestling; beside him is Alketos, son of Alkinous, of Kleitor, who gained victory in boys' boxing. Alketos' statue was made by Kleon, while that of Xenokles was executed by Polykleitos.
