Ancient Greek theatre originated in the 6th century BCE and was closely linked to religious festivals, particularly those honoring the god Dionysus. The performances took place in large outdoor amphitheaters, which were designed to enhance acoustics and visibility. The plays often featured themes of tragedy, comedy, and satyr plays, showcasing the complexities of human nature and society. The theatre was an important cultural institution in ancient Greece, with playwrights like Aeschylus, Sophocles, and Euripides contributing significantly to its development. Actors wore masks to portray different characters and emotions, while the chorus played a vital role in narrating the story and engaging the audience.
