At last, when the Mede was descending upon Hellas and the Athenians were deliberating who should be their general, all the rest, they say, voluntarily renounced their claims to the generalship, so panic-stricken were they at the danger; but Epicydes, the son of Euphemides, a popular leader who was powerful in speech but effeminate in spirit and open to bribes, set out to get the office, and was likely to prevail in the election; so Themistocles, fearing lest matters should go to utter ruin in case the leadership fell to such a man, bribed and bought off the ambition of Epicydes.
Praise is given to his treatment of the linguist in the company of those who were sent by the King to command earth and water as tokens of submission: this interpreter he caused to be arrested, and had him put to death by special decree, because he dared to prostitute the speech of Hellas to Barbarian stipulations.
Also to his treatment of Arthmius of Zeleia: on motion of Themistocles this man was entered on the list of the disfranchised, with his children and his family, because he brought the gold of the Medes and offered it to the Hellenes. But the greatest of all his achievements was his putting a stop to Hellenic wars, and reconciling Hellenic cities with one another, persuading them to postpone their mutual hatreds because of the foreign war. To which end, they say, Cheileos the Arcadian most seconded his efforts.
