Many are the proofs which we have given of our power and assuredly it does not lack witnesses, and therefore we shall be the wonder not only of the men of to-day but of after times; we shall need no Homer to sing our praise nor any other poet whose verses may perhaps delight for the moment but whose presentation of the facts will be discredited by the truth. Nay, we have compelled every sea and every land to grant access to our daring, and have everywhere planted everlasting memorials both of evil to foes and of good to friends.
Such, then, is the city for which these men nobly fought and died, deeming it their duty not to let her be taken from them; and it is fitting that every man who is left behind should suffer willingly for her sake.
"It is for this reason that I have dwelt upon the greatness of our city; for I have desired to show you that we are contending for a higher prize than those who do not enjoy such privileges in like degree, and at the same time to let the praise of these men in whose honour I am now speaking be made manifest by proofs.
Indeed, the greatest part of their praise has already been spoken; for when I lauded the city, that was but the praise wherewith the brave deeds of these men and men like them have already adorned her; and there are not many Hellenes whose fame would be found, like theirs, evenly balanced with their deeds. And it seems to me that such a death as these men died gives proof enough of manly courage, whether as first revealing it or as affording its final confirmation.
