Passage 6.21.6
ἐν ταύτῃ τῇ χώρᾳ λόφος ἐστὶν ἀνήκων ἐς ὀξύ, ἐπὶ δὲ αὐτῷ πόλεως Φρίξας ἐρείπια καὶ Ἀθηνᾶς ἐστιν ἐπίκλησιν Κυδωνίας ναός. οὗτος μὲν οὐ τὰ πάντα ἐστὶ σῶς, βωμὸς δὲ καὶ ἐς ἐμὲ ἔτι· ἱδρύσασθαι δὲ τῇ θεῷ τὸ ἱερὸν Κλύμενόν φασιν ἀπόγονον Ἡρακλέους τοῦ Ἰδαίου, παραγενέσθαι δὲ αὐτὸν ἀπὸ Κυδωνίας τῆς Κρητικῆς καὶ τοῦ Ἰαρδάνου ποταμοῦ. λέγουσι δὲ καὶ Πέλοπα οἱ Ἠλεῖοι τῇ Ἀθηνᾷ θῦσαι τῇ Κυδωνίᾳ πρὶν ἢ ἐς τὸν ἀγῶνα αὐτὸν τῷ Οἰνομάῳ καθίστασθαι.
In this region there is a hill rising sharply to a point, upon which lie the ruins of the city Phrixa and a temple of Athena, surnamed Cydonia. The temple is not in every respect intact, but the altar still remained even in my time. They say that Clymenus, a descendant of Heracles of Ida, founded this sanctuary for the goddess, having come here from Cydonia in Crete near the river Iardanus. The Eleians say as well that Pelops offered a sacrifice to Athena surnamed Cydonia before undertaking the contest itself against Oenomaus.
