Passage 7.17.14
οὕτω καὶ ἄλλα ἐς τιμήν σφισι τοῦ Οἰβώτα ποιήσασι καὶ τὴν εἰκόνα ἀναθεῖσιν ἐς Ὀλυμπίαν Σώστρατος Πελληνεὺς σταδίου νίκην ἔσχεν ἐν παισί. διαμένει δὲ ἐς ἐμὲ ἔτι Ἀχαιῶν τοῖς ἀγωνίζεσθαι μέλλουσι τὰ Ὀλύμπια ἐναγίζειν τῷ Οἰβώτᾳ, καὶ ἢν κρατήσωσιν, ἐν Ὀλυμπίᾳ στεφανοῦν τοῦ Οἰβώτα τὴν εἰκόνα.
Thus, having paid him other honors and having dedicated his statue at Olympia, Sostratos of Pellene won the footrace for boys. It continues even to my time that the Achaeans who intend to compete at Olympia offer sacrifices to Oebotas, and if they gain the victory, they crown the statue of Oebotas at Olympia.
