Passage 9.23.7
ὑπερβαλόντων δὲ τὸ ὄρος τὸ Πτῶον ἔστιν ἐπὶ θαλάσσης Βοιωτῶν πόλις Λάρυμνα, γενέσθαι δὲ αὐτῇ τὸ ὄνομά φασιν ἀπὸ Λαρύμνης τῆς Κύνου· τοὺς δὲ ἀνωτέρω προγόνους δηλώσει μοι τὰ ἔχοντα ἐς Λοκροὺς τοῦ λόγου. καὶ συνετέλει δὲ ἐς Ὀποῦντα ἡ Λάρυμνα τὸ ἀρχαῖον· Θηβαίων δὲ ἐπὶ μέγα ἰσχύος προελθόντων, τηνικαῦτα ἑκουσίως μετετάξαντο ἐς Βοιωτούς. Διονύσου δὲ ἐνταῦθα ναὸς καὶ ἄγαλμα ὀρθὸν πεποίηται. λιμὴν δέ σφισίν ἐστιν ἀγχιβαθής, καὶ τὰ ὄρη τὰ ὑπὲρ τὴν πόλιν ὑῶν παρέχεται θήραν ἀγρίων.
After crossing Mount Ptoon there is a city of the Boeotians called Larymna situated by the sea. They say it received its name from Larymna, the daughter of Cynus, and regarding her more remote ancestors, I shall reveal these when my account reaches the Locrians. Larymna originally contributed to Opus, but when the Thebans rose greatly in strength, the inhabitants willingly transferred allegiance to the Boeotians. There is a temple and a standing statue of Dionysus at Larymna. They also have a harbor with shallow water near the shore, and the mountains above the city offer hunting grounds for wild boars.
