Critias

Critias (Greek Κριτίας Kritias, 460 BC – 403 BC) was an ancient Athenian political figure and author. Born in Athens, Critias was the son of Callaeschrus and an uncle of Plato, and became a leading and violent member of the Thirty Tyrants. He was an associate of Socrates, a fact that did not endear Socrates to the Athenian public.
