Passage 7.18.3
ὡς δὲ πρὸς ὕπνον ἐτράπετο ὁ Τριπτόλεμος, ἐνταῦθα Ἀνθείαν παῖδα Εὐμήλου τοὺς δράκοντάς φασιν ὑπὸ τοῦ Τριπτολέμου τὸ ἅρμα ζεύξαντα ἐθελῆσαι καὶ αὐτὸν σπεῖραι· καὶ τὸν μὲν ἐπιλαμβάνει τὸ χρεὼν ἐκπεσόντα τοῦ ἅρματος, Τριπτόλεμος δὲ καὶ Εὔμηλος Ἄνθειαν πόλιν οἰκίζουσιν ἐν κοινῷ, τοῦ Εὐμήλου παιδὸς ἐπώνυμον.
When Triptolemus had retired to sleep, it is said that Antheias, son of Eumelus, yoked Triptolemus' dragons to the chariot and himself attempted to sow the seed. But fate overtook him, for he fell from the chariot. Afterwards, Triptolemus and Eumelus jointly founded the city Antheia, naming it after the son of Eumelus.
