Aristotle was the first major Greek philosopher to write a critical treatise on poetry and drama. He defined art as mimesis, or imitation of reality. For Aristotle, mimesis was not just mere copying but a technique that enhances meaning by representing the world and human experiences. Aristotle analyzed tragedy in detail and saw it as depicting the conflict between good and evil through the downfall of a noble protagonist. He also took a reader-centered approach by considering how drama impacts audiences. The tragic hero for Aristotle must be a noble and virtuous figure whose suffering evokes pity and fear in viewers.
