Writing at the time of political and social crisis in Athens, Aristophanes was an eloquent yet bawdy challenger to the demagogue and the sophist. The Achanians is a plea for peace set against the background of the long war with Sparta. In Lysistrata a band of women tap into the awesome power of sex in order to end a war. The darker comedy of The Clouds satirizes Athenian philosophers, Socrates in particular, and reflects the uncertainties of a generation in which all traditional religious and ethical beliefs were being challenged.
