Answer:There are five rules created by Aristotle that classify a tragedy. All plays must have catharsis, a tragic hero, a change in fortune within a character, must be poetic, and happen in one location, in one day, and it is all closely related.
In the story, Creon locks up Antigone in a chamber for her wrongdoings. He realizes that what he did was wrong. He has a change of mind, from good to bad. This is an example of change within a character.
Antigone is an example of a tragic hero because of everything that had happened to her throughout her life. She lost her father Oedipus through a curse and her brothers through battle.
