Passage 7.25.8
ἐκ Κερυνείας δὲ ἐπανελθόντι ἐς τὴν λεωφόρον καὶ ὁδεύσαντι οὐκ ἐπὶ πολὺ δεύτερα ἔστιν ἐς Βοῦραν ἀποτραπέσθαι· θαλάσσης δὲ ἐν δεξιᾷ καὶ ἡ Βοῦρα ἐν ὄρει κεῖται. τεθῆναι δέ φασι τῇ πόλει τὸ ὄνομα ἀπὸ γυναικὸς Βούρας, θυγατέρα δʼ αὐτὴν Ἴωνος τοῦ Ξούθου καὶ Ἑλίκης εἶναι. ὅτε δὲ Ἑλίκην ἐποίησεν ἄδηλον ἐξ ἀνθρώπων ὁ θεός, τότε καὶ τὴν Βοῦραν σεισμὸς ἐπέλαβεν ἰσχυρός, ὡς μηδὲ τὰ ἀγάλματα ἐν τοῖς ἱεροῖς ὑπολειφθῆναι τὰ ἀρχαῖα.
Returning from Ceryneia to the main road and travelling a short distance along it, one may take another turning towards Boura. The sea is to the right, while Boura itself lies upon a mountain. They say that the city took its name from Boura, a woman who was the daughter of Ion son of Xuthus and of Helice. When the god rendered Helice invisible to human sight, Boura too was visited by a vehement earthquake, such that not even the ancient statues within the sanctuaries were preserved.
