The father of Greek Drama is considered to be Aeschylus. He lived in Athens in the 5th century BCE and is credited with creating the art form of tragedy. His most famous works, such as "The Oresteia," explored complex themes such as justice, fate, and the nature of the gods. Aeschylus is also credited with introducing the use of multiple actors and a chorus to Greek drama, which expanded the possibilities for storytelling and theatrical performance. His innovations laid the foundation for the development of drama in ancient Greece and influenced theater throughout Western civilization.
