History of the Peloponnesian War

They to whom this charge was given were [the] Andrians, Tenians, three hundred Carystians, and such of the colony of Aegina which the Athenians had sent thither to inhabit, as came on purpose to this action with their own arms.

These things thus ordered, The Four Hundred, with every man a secret dagger, accompanied with one hundred and twenty young men of Greece, whom they used for occasions of shedding of blood, came in upon the Counsellers of the Bean as they sat in the council-house and commanded them to take their salary and be gone, which also they brought ready with them, for the whole time they were behind, and paid it to them as they went out.

And the rest of the citizens mutinied not, but rested quiet. The Four Hundred, being now entered into the councilhouse, created Prytanes amongst themselves by lot, and made their prayers and sacrifices to the gods, all that were before usual at the entrance upon the government.
