Passage 10.29.5
τὰ μὲν δὴ ἐς Διόνυσον πολλὰ ὑπό τε Ἑλλήνων λεγόμενα καὶ ὑπὸ Αἰγυπτίων ἐστίν· ὑπὸ δὲ τὴν Φαίδραν ἐστὶν ἀνακεκλιμένη Χλῶρις ἐπὶ τῆς Θυίας γόνασιν. οὐχ ἁμαρτήσεται μὲν δὴ οὐδὲ ὅστις φησὶ φιλίαν εἶναι ἐς ἀλλήλας, ἡνίκα ἔτυχον αἱ γυναῖκες ζῶσαι· ἦσαν γὰρ δὴ ἡ μὲν ἐξ Ὀρχομενοῦ τοῦ ἐν Βοιωτίᾳ ἡ Χλῶρις, ἡ δὲ Κασταλίου θυγάτηρ ἀπὸ τοῦ Παρνασσοῦ. εἶπον δʼ ἂν καὶ ἄλλοι τὸν ἐς αὐτὰς λόγον, τῇ μὲν συγγενέσθαι Ποσειδῶνα τῇ Θυίᾳ, Χλῶριν δὲ Ποσειδῶνος παιδὶ Νηλεῖ συνοικῆσαι.
There are many stories concerning Dionysus, told by both Greeks and Egyptians; below Phaedra stands Chloris, leaning upon the knees of Thyia. He who says there was friendship between these two women when they were alive will not be wrong. Chloris was from Orchomenus in Boeotia, while Thyia, daughter of Castalius, came from Parnassus. Others may also recount a tradition concerning them: that Poseidon was intimate with Thyia, and that Chloris was married to Neleus, the son of Poseidon.
