Passage 2.30.8
τοὺς δὲ ὕστερον βασιλεύσαντας οὐκ ἴσασιν ἄχρι Ὑπέρητος καὶ Ἄνθα· τούτους δὲ εἶναι Ποσειδῶνος καὶ Ἀλκυόνης Ἄτλαντος θυγατρός, καὶ πόλεις αὐτοὺς ἐν τῇ χώρᾳ φασὶν Ὑπέρειάν τε καὶ Ἄνθειαν οἰκίσαι· Ἀέτιον δὲ τὸν Ἄνθα τοῦ πατρὸς καὶ τοῦ θείου παραλαβόντα τὴν ἀρχὴν τὴν ἑτέραν τῶν πόλεων Ποσειδωνιάδα ὀνομάσαι. Τροίζηνος δὲ καὶ Πιτθέως παρὰ Ἀέτιον ἐλθόντων βασιλεῖς μὲν τρεῖς ἀντὶ ἑνὸς ἐγένοντο, ἴσχυον δὲ οἱ παῖδες μᾶλλον οἱ Πέλοπος.
Of those who reigned afterward, they do not know the names until we come to Hyperes and Anthas. These, they say, were sons of Poseidon and Alcyone, daughter of Atlas, and founded cities within the land, Hypereia and Antheia. When Aëtius, the son of Anthas, received authority from his father and uncle, he renamed one of these cities Poseidonia. After Troezen and Pittheus came to Aëtius, there were three kings instead of one, but the sons of Pelops possessed the greater power.
