Paragraph 213 213. Then when the king was in a strait as to what he should do in the matter before him, Epialtes the son of Eurydemos, a Malian, came to speech with him, supposing that he would win a very great reward from the king; and this man told him of the path which leads over the mountain to Thermopylai, and brought about the destruction of those Hellenes who remained in that place. Afterwards from fear of the Lacedemonians he fled to Thessaly, and when he had fled, a price was proclaimed for his life by the Deputies, 212 when the Amphictyons met for their assembly at Pylai. 213 Then some time afterwards having returned to Antikyra he was slain by Athenades a man of Trachis. Now this Athenades killed Epialtes for another cause, which I shall set forth in the following part of the history, 214 but he was honoured for it none the less by the Lacedemonians.
Paragraph 214 214. Thus Epialtes after these events was slain: there is however another tale told, that Onetes the son of Phanagoras, a man of Carystos, and Corydallos of Antikyra were those who showed the Persians the way round the mountain; but this I can by no means accept: for first we must judge by this fact, namely that the Deputies of the Hellenes did not proclaim a price for the lives of Onetes and Corydallos, but for that of Epialtes the Trachinian, having surely obtained the most exact information of the matter; and secondly we know that Epialtes was an exile from his country to avoid this charge. True it is indeed that Onetes might know of this path, even though he were not a Malian, if he had had much intercourse with the country; but Epialtes it was who led them round the mountain by the path, and him therefore I write down as the guilty man.
