Passage 9.22.5
οὗτοι μὲν τοιοῦτο παρέχονται τὸ εἶδος, τῆς δὲ Βοιωτίας τὰ ἐν ἀριστερᾷ τοῦ Εὐρίπου Μεσσάπιον ὄρος καλούμενον καὶ ὑπʼ αὐτῷ Βοιωτῶν ἐπὶ θαλάσσης πόλις ἐστὶν Ἀνθηδών· γενέσθαι δὲ τῇ πόλει τὸ ὄνομα οἱ μὲν ἀπὸ Ἀνθηδόνος νύμφης, οἱ δὲ Ἄνθαν δυναστεῦσαι λέγουσιν ἐνταῦθα, Ποσειδῶνός τε παῖδα καὶ Ἀλκυόνης τῆς Ἄτλαντος. Ἀνθηδονίοις δὲ μάλιστά που κατὰ μέσον τῆς πόλεως Καβείρων ἱερὸν καὶ ἄλσος περὶ αὐτό ἐστι, πλησίον δὲ Δήμητρος καὶ τῆς παιδὸς ναὸς καὶ ἀγάλματα λίθου λευκοῦ·
These places present such an aspect. On the left side of the Euripus, in Boeotia, is a mountain called Messapion, and beneath it by the sea is a Boeotian city called Anthedon. Regarding the city's name, some say it derived from a nymph named Anthedon, while others claim it was named after Anthas, who ruled there, and who was the son of Poseidon and Alcyone, daughter of Atlas. In the center of Anthedon especially is a sanctuary of the Cabeiri, surrounded by a grove, and nearby stands a temple of Demeter and her daughter, containing statues carved from white marble.
