Passage 9.39.1
τὰ μὲν δὴ πρὸς τῶν ὀρῶν Φωκεῖς ὑπεροικοῦσιν Ὀρχομενίων, ἐν δὲ τῷ πεδίῳ Λεβάδειά ἐστιν αὐτοῖς ὅμορος. αὕτη τὸ μὲν ἐξ ἀρχῆς ᾠκεῖτο ἐπὶ μετεώρου καὶ ὠνομάζετο Μίδεια ἀπὸ τῆς Ἀσπληδόνος μητρός· Λεβάδου δὲ ἐξ Ἀθηνῶν ἐς αὐτὴν ἀφικομένου κατέβησάν τε ἐς τὸ χθαμαλὸν οἱ ἄνθρωποι καὶ ἐκλήθη Λεβάδεια ἡ πόλις ἀπʼ αὐτοῦ. πατέρα δὲ τοῦ Λεβάδου, καὶ καθʼ ἥντινα αἰτίαν ἦλθεν, οὐκ ἴσασιν ἄλλο ἢ γυναῖκα εἶναι Λεβάδου Λαονίκην.
The Phocians dwell above Orchomenus, near the mountains, and in the plain below them lies Lebadeia, their neighbor. Originally this city stood upon high ground and was called Mideia, named after the mother of Aspledon. When Lebados arrived there from Athens, the people descended to the lower ground, and the city was afterward renamed Lebadeia after him. They do not know the father of Lebados or for what reason he came, but only that Lebados' wife was Laonike.
