History of the Peloponnesian War

"Concerning the truth of this invasion, though perhaps I shall be thought, as well as other men, to deliver a thing incredible, and though I know that such as be either the authors or relaters of matter incredible shall not only not persuade, but be also accounted fools, nevertheless, I will not fear thereof hold my tongue, as long as the commonwealth is in danger, being confident that I know the truth hereof somewhat more certainly than others do.

The Athenians are bent to come even against us (which you verily wonder at), and that with great forces both for the sea and land, with pretence indeed to aid their confederates the Egestaeans and replant the Leontines; but in truth they aspire to the dominion of all Sicily, and especially of this city of ours, which obtained, they make account to get the rest with ease.

Seeing then they will presently be upon us, advise with your present means how you may with most honour make head against them, that you may not be taken unprovided through contempt nor be careless through incredulity, and that such as believe it may not be dismayed with their audaciousness and power.
