Funeral Oration (41-45)

They declared to all men, by their victory in the sea-fight, that there is better hope for the venture shared with a few in the cause of freedom than for that in which numerous subjects of a king contend for their own servitude.

They made the fullest and fairest contribution in aid of the freedom of the Greeks by providing Themistocles as commander, most competent to speak and decide and act, and ships more numerous than those of all their allies, and men of the greatest experience. For indeed who among the rest of the Greeks could have vied with these in decision, in number, and in valor?

Hence it was just that they should receive from Greece without dispute the prize of prowess in the sea-fight, and reasonable that they should attain a prosperity in accord with the measure of their perils, having taught the barbarians of Asia that their own valor was genuine and native to their soil.

Then the Athenians, in anger, advised them, if they meant to be of this mind, to encompass the whole Peloponnese with a wall: for if they themselves, betrayed by the Greeks, should be united with the barbarians, these on their part would have no need of a thousand ships, nor would the wall at the Isthmus help its builders, since the empire of the sea would belong without hazard to the King.
