Passage 1.5.2
τῶν δὲ ἐπωνύμων---καλοῦσι γὰρ οὕτω σφᾶς---ἔστι μὲν Ἱπποθόων Ποσειδῶνος καὶ Ἀλόπης θυγατρὸς Κερκυόνος, ἔστι δὲ Ἀντίοχος τῶν παίδων τῶν Ἡρακλέους, γενόμενος ἐκ Μήδας Ἡρακλεῖ τῆς Φύλαντος, καὶ τρίτος Αἴας ὁ Τελαμῶνος, ἐκ δὲ Ἀθηναίων Λεώς· δοῦναι δὲ ἐπὶ σωτηρίᾳ λέγεται κοινῇ τὰς θυγατέρας τοῦ θεοῦ χρήσαντος. Ἐρεχθεύς τέ ἐστιν ἐν τοῖς ἐπωνύμοις, ὃς ἐνίκησεν Ἐλευσινίους μάχῃ καὶ τὸν ἡγούμενον ἀπέκτεινεν Ἰμμάραδον τὸν Εὐμόλπου· Αἰγεύς τέ ἐστι καὶ Οἰνεὺς Πανδίονος υἱὸς νόθος καὶ τῶν Θησέως παίδων Ἀκάμας.
Of the Eponymoi—as they call them—one is Hippothoön, the son of Poseidon and Alope, daughter of Cercyon; another is Antiochus, one of the sons of Heracles, born to Heracles by Meda, daughter of Phylas; the third is Ajax, son of Telamon. Of the Athenians is Leos, who is said to have given his daughters as an offering for the common safety, in obedience to an oracle of the god. Erechtheus also is counted among the Eponymoi; he defeated the Eleusinians in battle and slew Immaradus, the son of Eumolpus, their leader. Also included are Aegeus, Oeneus (the illegitimate son of Pandion), and Acamas, one of the sons of Theseus.
