Aristotle wrote about the ideal tragic hero and the traits a protagonist must have to be considered one. He writes in his book, The Poetics, that the tragic hero is a literary character who suffers more than he deserves, is noble but has a tragic flaw known as "hamartia", and usually demonstrates excessive pride otherwise known as "Hubris". Aristotle saw Sophocles' Oedipus Rex as the perfect tragedy. King Oedipus's hamartia is his anger which inevitably leads to his downfall, he demonstrates hubris throughout the play, and has a turning point in his life. Oedipus' Hamartia, excessive pride, and perepeteia demonstrate and prove that he is a tragic hero.
