Passage 6.3.2
μετὰ δὲ τὸν Χαιρέαν Μεσσήνιός τε παῖς Σόφιος καὶ ἀνὴρ Ἠλεῖος ἀνάκειται Στόμιος, καὶ τῷ μὲν τοὺς συνθέοντας τῶν παίδων παρελθεῖν, Στομίῳ δὲ πενταθλοῦντι ἐν Ὀλυμπίᾳ καὶ Νεμείων τρεῖς ὑπῆρξεν ἀνελέσθαι νίκας. τὸ δὲ ἐπίγραμμα τὸ ἐπʼ αὐτῷ καὶ τάδε ἐπιλέγει, τῆς ἵππου τε Ἠλείοις αὐτὸν ἡγούμενον ἀναστῆσαι τρόπαια καὶ ἄνδρα τοῖς πολεμίοις στρατηγοῦντα ἀποθανεῖν ὑπὸ τοῦ Στομίου, μονομαχήσαντά οἱ κατὰ πρόκλησιν·
After Chaireas, there are statues dedicated of Sophius, a boy from Messenia, and Stomius, a man from Elis. The boy surpassed his rivals in running, while Stomius, competing in the pentathlon, won three victories at Olympia and at the Nemean games. The inscription upon his statue further states that he also led the Eleans to victory in horse-racing and, commanding their forces, slew in single combat an enemy general who had challenged him.
