Passage 6.2.11
συγκατῆλθε μέντοι Μεσσηνίοις ἐς Πελοπόννησον καὶ ἡ περὶ τὸν ἀγῶνα τύχη τὸν Ὀλυμπικόν· ἐνιαυτῷ γὰρ ὕστερον τοῦ οἰκισμοῦ τοῦ Μεσσήνης ἀγόντων Ὀλύμπια Ἠλείων ἐνίκα στάδιον παῖδας ὁ Δαμίσκος οὗτος, καί οἱ καὶ πενταθλήσαντι ὕστερον ἐγένοντο ἐν Νεμέᾳ τε νῖκαι καὶ Ἰσθμοῖ.
The fortune of the Olympic contests also accompanied the Messenians upon their return into the Peloponnese. For, in the year following the founding of Messene, when the Eleans were celebrating the Olympian games, this very Damiskos won the footrace for boys; and afterward, when he competed as a pentathlete, he gained victories at both Nemea and Isthmia.
