Xenophon (c. 420-350 BCE)
“The laws are your own creation and it is the laws, above all, which have made you great. Abide by them and never attempt to do anything without their sanction.”
- A History of My Times (Hellenica, I.7.29) by Xenophon, translated by Rex Warner. New York: Penguin Classics, 1966, 1979.
