Passage 10.7.2
ἀρχαιότατον δὲ ἀγώνισμα γενέσθαι μνημονεύουσι καὶ ἐφʼ ᾧ πρῶτον ἆθλα ἔθεσαν, ᾆσαι ὕμνον ἐς τὸν θεόν· καὶ ᾖσε καὶ ἐνίκησεν ᾄδων Χρυσόθεμις ἐκ Κρήτης, οὗ δὴ ὁ πατὴρ λέγεται Καρμάνωρ καθῆραι Ἀπόλλωνα. Χρυσοθέμιδος δὲ ὕστερον Φιλάμμωνά τε ᾠδῇ μνημονεύουσι νικῆσαι καὶ ἐπʼ ἐκείνῳ Θάμυριν τὸν Φιλάμμωνος. Ὀρφέα δὲ σεμνολογίᾳ τῇ ἐπὶ τελεταῖς καὶ ὑπὸ φρονήματος τοῦ ἄλλου καὶ Μουσαῖον τῇ ἐς πάντα μιμήσει τοῦ Ὀρφέως οὐκ ἐθελῆσαί φασιν αὐτοὺς ἐπὶ ἀγῶνι μουσικῆς ἐξετάζεσθαι.
They record that the most ancient contest held, and that upon which prizes were first bestowed, was the singing of a hymn to the god. The first victor who sang and prevailed was Chrysothemis from Crete, whose father, Carmanor, is said to have purified Apollo. After Chrysothemis, Philammon is mentioned as victorious in song, and following him Thamyris, son of Philammon. But Orpheus, because of the solemn nature of his rites and his greater loftiness of mind, and Musaeus, owing to his close imitation of all Orpheus' practices, declined, it is said, to subject themselves to musical competition.
