Greek drama was created to worship Dionysus, the god of wine. Tragedies featured noble protagonists who made a fatal error or hamartia that led to their downfall, arousing pity and fear in audiences. Comedies used satire to comment on life in Athens. Aristotle established rules for tragedies including that the protagonist must fall from high status due to a tragic flaw and face conflicts with fate alone, resulting in a catharsis for audiences. Oedipus from Oedipus the King is an example of a tragic hero who discovers his own tragic fate through his actions.
