Herodotus - Advice for Rulers

King Croesus to his vanquisher Cyrus on how to pacify his new subjects, as related by Herodotus in The Histories:

“What end to this business, Croesus? It seems that the Lydians will never stop making trouble for me and for themselves. It occurs to me that it may be best to make slaves of them; for it seems I have acted like one who slays the father and spares the children. So likewise I have taken with me you who were more than a father to the Lydians, and handed the city over to the Lydians themselves; and then indeed I marvel that they revolt!” 

So Cyrus uttered his thought; but Croesus feared that he would destroy Sardis, and answered him thus: “O King, what you say is reasonable. But do not ever yield to anger, or destroy an ancient city that is innocent both of the former and of the present offense. For the former I am responsible, and bear the punishment on my head; while Pactyes, in whose charge you left Sardis, does this present wrong; let him, then, pay the penalty. But pardon the Lydians, and give them this command so that they not revolt or pose a danger to you: send and forbid them to possess weapons of war, and order them to wear tunics under their cloaks and knee-boots on their feet, and to teach their sons lyre-playing and song and dance and shop-keeping. And quickly, O king, you shall see them become women instead of men, so that you need not fear them, that they might revolt.”
