History of the Peloponnesian War

Now tidings of the expedition were brought to Syracuse from many quarters, but for a long time received no credit at all. Nay, even when an assembly was held on the subject, both by others were speeches to the following effect delivered, (some believing the report of the Athenian expedition, while some contradicted it,) and Hermocrates, the son of Hermon, coming forward to them, from a conviction that he had accurate information on the subject, addressed to them the following advice:

"I shall, perhaps, appear to you, as some others have done, to speak what is incredible concerning the reality of the expedition that is coming against us: and I know that those who either make statements, or bring reports, which do not seem to be credible, not only fail to convince, but are also thought to be foolish. Nevertheless I will not, through fear of this, hold my tongue when the state is in danger, since I am myself at any rate persuaded that I speak with more certain knowledge than others.
