This document summarizes Aristotle's work "The Poetics" and its key ideas. It discusses how Aristotle's views on poetry and tragedy differed from his teacher Plato's, defining tragedy as "an imitation of an action, serious, complete and of a certain magnitude." It examines Aristotle's analysis of the six elements of tragedy - plot, character, thought, diction, song and spectacle. It also describes Aristotle's concepts of the ideal tragic hero and the dramatic unities of time, place and action. The document was prepared by Ashish Trivedi for a class at Bhavnagar University.
