Дефиниция "трагедии" на англ. яз. из "Поэтики" Аристотеля
In Poetics, one of the first books of literary criticism, Aristotle set out the key features of tragedy. He stated that tragic plays would involve a protagonist (the leading central figure) who is usually of royal or noble birth. In the course of the play, the protagonist reveals a fatal flaw (a character defect) which causes him or her to go from success and happiness to failure, misery and, often, death at the hands of an antagonist (his opposite). Tragedy set out to stir up feelings of fear and pity in the audience - this is known as catharsis
