Ancient Greek theater originated in Athens in the 6th century BC and was highly influential on later Western traditions of drama and theater. Tragedies and comedies were performed as part of religious festivals honoring the god Dionysus. Tragedies dealt with serious themes and featured a tragic hero, while comedies aimed to provoke laughter through criticism of customs. Satyr plays were also performed as lighthearted entertainment between tragedies. Theater performances took place outdoors and involved masks, costumes, singing, and dancing. The legacy of Greek drama continues to influence modern theater.
