Passage 6.17.6
εἶναι δὲ καὶ μάντις ὁ Ἐπέραστος τοῦ Κλυτιδῶν γένους φησὶν ἐπὶ τοῦ ἐπιγράμματος τῇ τελευτῇ, τῶν δʼ ἱερογλώσσων Κλυτιδᾶν γένος εὔχομαι εἶναι μάντις, ἀπʼ ἰσοθέων αἷμα Μελαμποδιδᾶν. Μελάμποδος γὰρ ἦν τοῦ Ἀμυθάονος Μάντιος, τοῦ δὲ Ὀικλῆς, Κλυτίος δὲ Ἀλκμαίωνος τοῦ Ἀμφιαράου τοῦ Ὀϊκλέους· ἐγεγόνει δὲ τῷ Ἀλκμαίωνι ὁ Κλυτίος ἐκ τῆς Φηγέως θυγατρὸς καὶ ἐς τὴν Ἦλιν μετῴκησε, τοῖς ἀδελφοῖς εἶναι τῆς μητρὸς σύνοικος φεύγων, ἅτε τοῦ Ἀλκμαίωνος ἐπιστάμενος σφᾶς εἰργασμένους τὸν φόνον.
Eperastus was also a seer, according to the epitaph upon his tomb, which says: "I proudly claim descent from the priestly line of the Klytidae, a seer, a scion of the Melampodidae, descendants of godlike men." For Mantius was the son of Melampus, son of Amythaon; from Mantius came Oicles, and from Oicles came Amphiaraus, whose son Alcmaeon was the father of Clytius. This Clytius was born to Alcmaeon by the daughter of Phegeus, and migrated to Elis, fleeing to dwell with his mother's brothers, since he knew that they had slain his father Alcmaeon.
