Passage 10.7.7
ὀγδόῃ δὲ πυθιάδι προσενομοθέτησαν κιθαριστὰς τοὺς ἐπὶ τῶν κρουμάτων τῶν ἀφώνων· καὶ Τεγεάτης ἐστεφανοῦτο Ἀγέλαος. τρίτῃ δὲ πυθιάδι ἐπὶ ταῖς εἴκοσι προστιθέασιν ὁπλίτην δρόμον· καὶ ἐπʼ αὐτῷ Τιμαίνετος ἐκ Φλιοῦντος ἀνείλετο τὴν δάφνην, Ὀλυμπιάσιν ὕστερον πέντε ἢ Δαμάρετος Ἡραιεὺς ἐνίκησεν. ὀγδόῃ δὲ ἐπὶ τεσσαράκοντα πυθιάδι καὶ συνωρίδος εἶναι κατεστήσαντο δρόμον· καὶ Ἐξηκεστίδου Φωκέως ἐνίκησεν ἡ συνωρίς. πέμπτῃ δὲ πυθιάδι ἀπὸ ταύτης πώλους ἔζευξαν ὑπὸ ἅρματι· καὶ παρέδραμεν Ὀρφώνδα Θηβαίου τέθριππον.
In the eighth Pythian festival they added a musical contest for lyre-players who performed instrumental music without voice, and Agelaus of Tegea won the crown. At the third Pythiad after the twentieth, they introduced the race in arms; the laurel in this competition was won by Timainetos of Phlius, five Olympiads after Damaretos of Heraea was victorious at Olympia. At the forty-eighth Pythiad, they established a race for two-horse chariots, and the pair belonging to Exaikestides of Phocis were the victors. In the fifth Pythiad following this, they yoked foals to a chariot, and the chariot of Orphondas of Thebes outran the others.
