Passage 8.5.7
Ὁλαίας δὲ ἦν Κυψέλου παῖς, ὃς καὶ τῆς ἀδελφῆς τὸν παῖδα Αἴπυτον, σὺν δὲ αὐτῷ καὶ οἱ ἐκ Λακεδαίμονος καὶ Ἄργους Ἡρακλεῖδαι κατάγουσιν ἐς Μεσσήνην. τοῦ δὲ ἦν Βουκολίων, τοῦ δὲ Φίαλος, ὃς τὸν Λυκάονος Φίγαλον οἰκιστὴν ὄντα ἀφελόμενος τὴν τιμὴν Φιαλίαν τὸ ὄνομα τῇ πόλει μετέθετο ἀφʼ ἑαυτοῦ· οὐ μὴν καὶ ἐς ἅπαν γε ἐξενίκησεν.
Olaeas was the son of Cypselus. Along with Aepytus, the son of his sister, and together with the Heracleidae from Lacedaemon and Argos, he led a return to Messene. Olaeas had a son, Bucolion, whose son was Phialus. This Phialus robbed Phigalus, the founder and son of Lycaon, of his honor, renaming the city after himself—Phialia. Nevertheless, he was not entirely successful in asserting this new name.
