Passage 2.34.9
ἐπίκλησις δέ ἐστι τῇ θεῷ Προμαχόρμα. πρόκειται δὲ Βουπόρθμου νῆσος Ἀπεροπία καλουμένη, τῆς δὲ Ἀπεροπίας ἀφέστηκεν οὐ πολὺ ἑτέρα νῆσος Ὑδρέα. μετὰ ταύτην αἰγιαλός τε παρήκει τῆς ἠπείρου μηνοειδὴς καὶ ἀκτὴ μετὰ τὸν αἰγιαλὸν ἐπὶ Ποσείδιον, ἐκ θαλάσσης μὲν ἀρχομένη τῆς πρὸς ἀνατολάς, προήκουσα δὲ ὡς ἐπὶ τὴν ἑσπέραν· ἔχει δὲ καὶ λιμένας ἐν αὑτῇ. μῆκος μὲν δὴ τῆς ἀκτῆς ἐστιν ἑπτά που στάδια, πλάτος δὲ ᾗ πλατυτάτη σταδίων τριῶν οὐ πλέον.
The goddess bears the surname Promachorma. In front lies the island of Aperopia, belonging to Bouporthmos; not far from Aperopia lies another island called Hydrea. Beyond this island, on the mainland, the coast curves like a crescent, after which extends a headland running out from the shore towards Poseidion, beginning from the sea on the east side and projecting toward the west. It has harbors within it. The length of this headland is about seven stades, but where it is widest, it does not exceed three stades in breadth.
