Aristophanes ( c. 446 - c. 386 BC), son of Philippus, was a comic playwright of ancient Athens. Eleven of his forty plays survive virtually complete. Also known as "The Father of Comedy", Aristophanes depicted the life of ancient Athens and ridiculed authority leading to a case of slander brought by Plato which led to Socrates' death. Aristophanes' second play,The Babylonians (now lost), was denounced too, this time by Cleon but details of any subsequent trial are unknown and Aristophanes went on to caricature Cleon in his later plays, especially in The Knights.
