Passage 2.30.5
Αἰγίνης μὲν δὴ Αἰακοῦ ἕνεκα καὶ ἔργων ὁπόσα ἀπεδείξατο ἐς τοσόνδε ἔστω μνήμη· τῆς δὲ Ἐπιδαυρίας ἔχονται Τροιζήνιοι, σεμνύνοντες εἴπερ καὶ ἄλλοι τινὲς τὰ ἐγχώρια· φασὶ δὲ Ὦρον γενέσθαι σφίσιν ἐν τῇ γῆ πρῶτον. ἐμοὶ μὲν οὖν Αἰγύπτιον φαίνεται καὶ οὐδαμῶς Ἑλληνικὸν ὄνομα Ὦρος εἶναι· βασιλεῦσαι δʼ οὖν φασιν αὐτὸν καὶ Ὠραίαν ἀπʼ αὐτοῦ καλεῖσθαι τὴν γῆν, Ἄλθηπον δὲ Ποσειδῶνος παῖδα καὶ Ληίδος τῆς Ὤρου, παραλαβόντα μετὰ Ὦρον τὴν ἀρχήν, Ἀλθηπίαν ὀνομάσαι τὴν γῆν.
So much then for Aegina, commemorated thus far on account of Aeacus and the deeds he accomplished. Next to Epidauria lie the lands of the Troezenians, who proudly uphold their local traditions as much as any others do. They assert that in their land Horus was first born. But to me the name Horus seems clearly Egyptian and in no way Greek. Nevertheless, they say that he ruled as king, and from him their country was named Oraia (Horeia); and afterwards Althepus, son of Poseidon and Leïs, daughter of Horus, shared the sovereignty with Horus and renamed the land Althepia.
