Passage 2.30.10
Ἡρακλειδῶν γὰρ κατελθόντων ἐδέξαντο καὶ οἱ Τροιζήνιοι συνοίκους Δωριέων τῶν ἐξ Ἄργους καὶ πρότερον ἔτι Ἀργείων ὄντες κατήκοοι· καὶ σφᾶς καὶ Ὅμηρος ἐν καταλόγῳ φησὶν ὑπὸ Διομήδους ἄρχεσθαι. Διομήδης γὰρ καὶ Εὐρύαλος ὁ Μηκιστέως Κυάνιππον τὸν Αἰγιαλέως παῖδα ὄντα ἐπιτροπεύοντες Ἀργείων ἡγήσαντο ἐς Τροίαν. Σθένελος δέ, ὡς ἐδήλωσα ἐν τοῖς πρότερον, οἰκίας τε ἦν ἐπιφανεστέρας, τῶν Ἀναξαγοριδῶν καλουμένων, καὶ ἡ βασιλεία τούτῳ μάλιστα ἦν ἡ Ἀργείων προσήκουσα. τοσαῦτα Τροιζηνίοις ἐχόμενα ἱστορίας ἦν, παρὲξ ἢ ὅσαι πόλεις παρʼ αὐτῶν φασιν ἀποικισθῆναι· κατασκευὴν δὲ ἱερῶν καὶ ὅσα ἄλλα ἐς ἐπίδειξιν, τὸ ἐντεῦθεν ἐπέξειμι.
For when the Heracleidae returned, the Troezenians also welcomed as fellow inhabitants Dorians from Argos, having previously been obedient subjects to the Argives. Indeed, even Homer places them in the Catalogue under the command of Diomedes. For Diomedes and Euryalus, the son of Mecisteus, acting as guardians for Cyanippus, son of Aegialeus, led the Argives to Troy. But Sthenelus, as I have previously noted, belonged to a more distinguished family—known as the house of the Anaxagoridae—and the kingship of Argos properly belonged to him above all. Such then is the history involving the Troezenians, apart from the cities which, according to their account, were founded as colonies by them. Now I shall proceed to describe their sacred buildings and all else that is noteworthy.
