Passage 2.6.1
Κόρακος δὲ ἀποθανόντος ἄπαιδος ὑπὸ τοῦτον τὸν καιρὸν Ἐπωπεὺς ἀφικόμενος ἐκ Θεσσαλίας ἔσχε τὴν ἀρχήν. ἐπὶ τούτου βασιλεύοντος στρατόν σφισι πολέμιον λέγουσιν ἐς τὴν χώραν τότε ἐλθεῖν πρῶτον, τὰ πρὸ τοῦ πάντα τὸν χρόνον διατελέσασιν ἐν εἰρήνῃ. αἰτία δὲ ἥδε· Ἀντιόπης ἐν Ἕλλησι τῆς Νυκτέως ὄνομα ἦν ἐπὶ κάλλει, καί οἱ καὶ φήμη προσῆν Ἀσωποῦ θυγατέρα, ὃς τὴν Θηβαΐδα καὶ Πλαταιίδα ὁρίζει, καὶ οὐ Νυκτέως εἶναι.
Upon the death of Corax, who left no children, Epopeus arrived at that time from Thessaly and took over the kingdom. They say that during his reign an enemy army first invaded their land, whereas before that time they had always lived in peace. The reason for this invasion is as follows: Antiope, daughter of Nycteus, was renowned among the Greeks for her beauty; moreover, a rumor spread that she was the daughter not of Nycteus but of Asopus, the river that forms the boundary between Theban and Plataean lands.
