Early Greek theatre developed in amphitheatres and included both comedies and tragedies. Comedies often used crude humor and satire, while tragedies featured a chorus and masked male actors. One famous tragedy, Oedipus Rex by Sophocles, tells the story of Oedipus who unknowingly fulfills a prophecy that he will kill his father and marry his mother, resulting in him blinding himself in horror once the truth is revealed.
