History of the Peloponnesian War

With good courage, then, let us both make our preparations here, and send to the Sicels, to strengthen the attachment of some of them, and endeavour to enter into friendship and alliance with others; while we despatch envoys to the rest of Sicily, to prove that the danger is common to all; and to Italy, that either we may gain their alliance for ourselves, or they may refuse to receive the Athenians.

I think it better, too, that we should also send to Carthage. For this is nothing unexpected by them; but they are always in fear that they may some time or other find the Athenians coming against their country; and therefore thinking, perhaps, that if they abandoned these places, they would themselves be brought into trouble, they might be willing to assist us; at least secretly, if not openly; or at any rate in some way or other. And they are more able to do it, if they please, than any men of the present day; for they possess most gold and silver; and it is by means of these that war, like every thing else, prospers.
