History of the Peloponnesian War

When the news were brought to Hippias in the Ceramicus, he proceeded immediately, not to the scene of action, but to the armed men in the procession, before they were aware of the matter, in consequence of their being at some distance from the spot; and with his countenance feigned to suit the occasion, so as not to betray his feelings, he pointed out a certain spot, and desired them to retire into it without their arms.

Accordingly they withdrew, supposing that he would deliver an address to them; while he, after commanding his guards to remove the arms, immediately picked out such men as he was disposed to think guilty, and whoever was found with a dagger; for it was only with shield and spear that they were accustomed to make their processions.
