Passage 7.21.7
ἀπὸ δὲ τοῦ Αἰσυμνήτου κατωτέρω ἰόντι ἄλλο ἱερὸν καὶ ἄγαλμα λίθου· καλεῖται μὲν Σωτηρίας, ἱδρύσασθαι δὲ αὐτὸ ἐξ ἀρχῆς ἀποφυγόντα φασὶ τὴν μανίαν Εὐρύπυλον. πρὸς δὲ τῷ λιμένι Ποσειδῶνός τε ναὸς καὶ ἄγαλμά ἐστιν ὀρθὸν λίθου. Ποσειδῶνι δὲ παρὲξ ἢ ὁπόσα ὀνόματα ποιηταῖς πεποιημένα ἐστὶν ἐς ἐπῶν κόσμον καὶ ἰδίᾳ σφίσιν ἐπιχώρια ὄντα ἕκαστοι τίθενται, τοσαίδε ἐς ἅπαντας γεγόνασιν ἐπικλήσεις αὐτῷ, Πελαγαῖος καὶ Ἀσφάλιός τε καὶ Ἵππιος.
Below Aesymnetes, as one goes further down, there is another sanctuary and a stone image. It is called the sanctuary of Soteria, and they say it was originally founded by Eurypylus after escaping from madness. Near the harbor is a temple and a standing stone image of Poseidon. In addition to those names of Poseidon created by poets as decorative epithets in verse, and those that various places assign to him as their own local titles, there are three epithets common to all Greeks: Pelagaios ("of the Sea"), Asphalios ("Securing Safe Passage"), and Hippios ("Horse God").
