Passage 7.10.2
μετὰ δὲ Ἴωνας κεχειρωμένους ἠνδραποδίσαντο καὶ Ἐρέτριαν Μῆδοι, προδόται δὲ ἐγένοντο οἱ εὐδοκιμοῦντες μάλιστα ἐν Ἐρετρίᾳ Φίλαγρος Κυνέου καὶ Εὔφορβος Ἀλκιμάχου. Ξέρξῃ δὲ ἐπὶ τὴν Ἑλλάδα ἐλαύνοντι Θεσσαλία τε διʼ Ἀλευάδου προεδόθη, Θήβας δὲ Ἀτταγῖνος καὶ Τιμηγενίδας προδιδόασι φερόμενοι τὰ πρῶτα ἐν Θήβαις. Πελοποννησίων δὲ καὶ Ἀθηναίων πολεμησάντων Ξενίας Ἠλεῖος ἐπεχείρησεν Ἦλιν Λακεδαιμονίοις καὶ Ἄγιδι προδοῦναι, οἵ τε Λυσάνδρου καλούμενοι ξένοι χρόνον
After defeating the Ionians, the Medes enslaved Eretria as well. The traitors who betrayed the city were Philagros son of Kyneos and Euphorbus son of Alkimachos, who enjoyed considerable renown in Eretria. When Xerxes marched upon Greece, Thessaly was betrayed through the Aleuadai, and Thebes was handed over by Attaginos and Timegenidas, men highly esteemed among the Thebans. Later, while the Athenians and Peloponnesians were at war, Xenias, an Eleian, tried to betray Elis to Agis and the Spartans, as did those known as Lysander's guests at one time.
