Passage 2.6.4
καὶ ἐπὶ τούτῳ πεποίηκεν Ἄσιος ὁ Ἀμφιπτολέμου· Ἀντιόπη δʼ ἔτεκε Ζῆθον καὶ Ἀμφίονα δῖον Ἀσωποῦ κούρη ποταμοῦ βαθυδινήεντος, Ζηνί τε κυσαμένη καὶ Ἐπωπέι ποιμένι λαῶν. Asius, unknown work Ὅμηρος δὲ σφᾶς ἀνήγαγεν ἐπὶ τὸ σεμνότερον τοῦ γένους καὶ Θήβας φησὶν οἰκίσαι πρώτους, ἀποκρίνων τὴν κάτω πόλιν ἐμοὶ δοκεῖν ἀπὸ τῆς Καδμείας.
About these two Asius son of Amphiptolemus has composed the following lines: "And Antiope, daughter of deep-eddying Asopus river, bore Zethus and godlike Amphion, conceiving them of Zeus and of Epopeus, shepherd of peoples." But Homer has attributed to them a nobler lineage, saying that they first founded Thebes, distinguishing, it seems to me, the lower city from the Cadmeia.
