Passage 2.4.1
τάδε μὲν οὕτως ἔχοντα ἐπελεξάμην, τοῦ μνήματος δέ ἐστιν οὐ πόρρω Χαλινίτιδος Ἀθηνᾶς ἱερόν· Ἀθηνᾶν γὰρ θεῶν μάλιστα συγκατεργάσασθαι τά τε ἄλλα Βελλεροφόντῃ φασὶ καὶ ὡς τὸν Πήγασόν οἱ παραδοίη χειρωσαμένη τε καὶ ἐνθεῖσα αὐτὴ τῷ ἵππῳ χαλινόν. τὸ δὲ ἄγαλμα τοῦτο ξόανόν ἐστι, πρόσωπον δὲ καὶ χεῖρες καὶ ἀκρόποδες εἰσὶ λευκοῦ λίθου.
Having described these matters as they are, I next speak of a sanctuary of Athena Chalinitis, located not far from this tomb. Of all the gods, they especially say that Athena assisted Bellerophon most notably, both in general ways and particularly by giving him Pegasus, who had been subdued, and herself placing a bridle upon the horse. The statue is a wooden image, but with the face, hands, and feet made of white marble.
