Classical Greek literature developed from an oral tradition of storytelling between the 8th and 5th centuries BC. Homer's epic poems The Iliad and The Odyssey were some of the first literary works written down in this period. In the 5th century BC, Greek theater blossomed with the innovations of playwrights like Aeschylus, Sophocles, and Euripides establishing tragic drama, and Aristophanes pioneering comic plays. Philosophy also advanced through the works of Socrates, Plato, and Aristotle, establishing foundations of Western thought.
