Passage 10.24.4
ἐν δὲ τῷ ναῷ πεποίηται μὲν Ποσειδῶνος βωμός, ὅτι τὸ μαντεῖον τὸ ἀρχαιότατον κτῆμα ἦν καὶ Ποσειδῶνος, ἕστηκε δὲ καὶ ἀγάλματα Μοιρῶν δύο· ἀντὶ δὲ αὐτῶν τῆς τρίτης Ζεύς τε Μοιραγέτης καὶ Ἀπόλλων σφίσι παρέστηκε Μοιραγέτης. θεάσαιο δʼ ἂν ἐνταῦθα καὶ ἑστίαν, ἐφʼ ᾗ Νεοπτόλεμον τὸν Ἀχιλλέως ὁ ἱερεὺς ἀπέκτεινε τοῦ Ἀπόλλωνος· τὰ δὲ ἐς τοῦ Νεοπτολέμου τὴν τελευτήν ἐστιν ἡμῖν ἑτέρωθι εἰρημένα.
In the temple there is an altar dedicated to Poseidon, because the most ancient oracle had once belonged also to Poseidon; and there stand images of two of the Fates. Instead of the third Fate, Zeus Moiragetes and Apollo Moiragetes are standing beside them. You may also see there the hearth upon which the priest of Apollo slew Neoptolemus, the son of Achilles. But concerning the death of Neoptolemus, I have spoken elsewhere.
