Passage 7.22.10
αἵδε μὲν οὖν θαλάσσης τέ εἰσιν ἀπωτέρω πόλεις καὶ ἠπειρώτιδες βεβαίως· πλέοντι δὲ ἐς Αἴγιον ἐκ Πατρῶν ἄκρα πρῶτόν ἐστιν ὀνομαζομένη Ῥίον, σταδίους δὲ Πατρῶν πεντήκοντα ἀπέχουσα, λιμὴν δὲ ὁ Πάνορμος σταδίοις πέντε καὶ δέκα ἀπωτέρω τῆς ἄκρας. τοσούτους δὲ ἀφέστηκεν ἑτέρους ἀπὸ Πανόρμου τὸ Ἀθηνᾶς καλούμενον τεῖχος. ἐς δὲ λιμένα Ἐρινεὸν ἐξ Ἀθηνᾶς τείχους παράπλους ἐνενήκοντά εἰσι στάδιοι, ἑξήκοντα δὲ ἐς Αἴγιον ἀπὸ τοῦ Ἐρινεοῦ· ὁδὸς δὲ ἡ πεζὴ σταδίους τεσσαράκοντα μάλιστα ἐς τὸν ἀριθμὸν ἀποδεῖ τὸν εἰρημένον.
These cities, then, lie inland away from the sea and are firmly situated on the mainland. Sailing from Patrae towards Aegium, one first encounters the promontory named Rhion, at a distance of fifty stades from Patrae. Fifteen stades further than this promontory lies the harbor called Panormus, and at an equal distance again from Panormus is the place known as the Wall of Athena. Sailing from the Wall of Athena to the harbor Erineus is a voyage of ninety stades, and from Erineus to Aegium it is sixty stades. The land route falls short of that number by roughly forty stades.
