Passage 8.4.6
ἀπὸ δὲ Ἐλάτου τῶν παίδων Κυλλήνην τὸ ὄρος καλοῦσιν ἀπὸ Κυλλῆνος, καὶ ἀπὸ Στυμφήλου πηγή τε ὀνομάζεται καὶ πόλις Στύμφηλος ἐπὶ τῇ πηγῇ. τὰ δὲ ἐς τὸν θάνατον Ἴσχυος τοῦ Ἐλάτου πρότερον ἔτι ἐν τῇ συγγραφῇ τῇ Ἀργολίδι ἐδήλωσα. παῖδα δὲ Περεῖ ἄρρενα μέν φασιν οὐδένα, Νέαιραν δὲ γενέσθαι θυγατέρα· ταύτην γυναῖκα ἔσχεν Αὐτόλυκος, οἰκῶν μὲν ἐν τῷ ὄρει τῷ Παρνασσῷ, λεγόμενος δὲ Ἑρμοῦ παῖς εἶναι, Δαιδαλίωνος δὲ ὢν τῷ ἀληθεῖ λόγῳ.
From Elatus' children they call the mountain Cyllene, after Cyllen, and from Stymphalus a spring is named, as well as the city Stymphalus by the spring. Regarding the death of Ischys, son of Elatus, I have previously related this in my writings on Argolis. As for Pereus, they say he had no male child, but a daughter, Neaera. This woman became the wife of Autolykos, who lived on Mount Parnassus, and was reputed to be the son of Hermes, though in truth he was the son of Daedalion.
