§7.213.1ἀπορέοντος δὲ βασιλέος ὅ τι χρήσηται τῷ παρεόντι πρήγματι, Ἐπιάλτης ὁ Εὐρυδήμου ἀνὴρ Μηλιεὺς ἦλθέ οἱ ἐς λόγους·
While the king was at a loss as to how to deal with the present situation, Ephialtes, son of Eurydemus, a Malian, came to speak with him.
ὃς μέγα τι παρὰ βασιλέος δοκέων οἴσεσθαι ἔφρασέ τε τὴν ἀτραπὸν τὴν διὰ τοῦ ὄρεος φέρουσαν ἐς Θερμοπύλας, καὶ διέφθειρε τοὺς ταύτῃ ὑπομείναντας Ἑλλήνων.
Expecting to win a great reward from the king, he revealed the path that led through the mountain to Thermopylae, and brought ruin upon those of the Greeks who held their ground there.
§7.213.2ὕστερον δὲ δείσας Λακεδαιμονίους ἔφυγε ἐς Θεσσαλίην, καί οἱ φυγόντι ὑπὸ τῶν Πυλαγόρων τῶν Ἀμφικτυόνων ἐς τὴν Πυλαίην συλλεγομένων ἀργύριον ἐπεκηρύχθη.
Later, fearing the Lacedaemonians, he fled to Thessaly, and while he was in exile, a price was put on his head by the Amphictyonic deputies (Pylagori) assembled at Pylae.
χρόνῳ δὲ ὕστερον, κατῆλθε γὰρ ἐς Ἀντικύρην, ἀπέθανε ὑπὸ Ἀθηνάδεω ἀνδρὸς Τρηχινίου.
Some time afterwards, for he had returned to Anticyra, he was killed by Athenades, a man of Trachis.
§7.213.3ὁ δὲ Ἀθηνάδης οὗτος ἀπέκτεινε μὲν Ἐπιάλτεα διʼ ἄλλην αἰτίην, τὴν ἐγὼ ἐν τοῖσι ὄπισθε λόγοισι σημανέω, ἐτιμήθη μέντοι ὑπὸ Λακεδαιμονίων οὐδὲν ἧσσον.
This Athenades killed Ephialtes for another reason, which I shall declare in the later part of my history, but he was honored by the Lacedaemonians no less on that account.
