Passage 2.34.5
ἐγὼ δέ, εἰ καὶ γνήσιον ὄντα Εὔρωπα πρότερον τὸ χρεὼν ἢ Φορωνέα ἐπέλαβεν, εὖ οἶδα ὡς οὐκ ἔμελλεν ὁ παῖς αὐτῷ Νιόβης παιδὶ ἴσα οἴσεσθαι Διός γε εἶναι δοκοῦντι. ἐπῴκησαν δὲ καὶ Ἑρμιόνα ὕστερον Δωριεῖς οἱ ἐξ Ἄργους· πόλεμον δὲ οὐ δοκῶ γενέσθαι σφίσιν, ἐλέγετο γὰρ ἂν ὑπὸ Ἀργείων.
But as for me, even if Europs was truly genuine but was overtaken by destiny earlier than Phoroneus, I am quite certain that his son would still not have been considered equal to the son of Niobe, who was believed to be of Zeus. Later, the Dorians who arrived from Argos also settled Hermione; and I do not think there was war between them, for it would have been mentioned by the Argives.
