The document discusses the concept of a tragic hero in Greek literature and Euripides' play Medea. While Jason is typically seen as the tragic hero, there is an argument that he does not fulfill all the requirements since he does not realize his own flaws have led to his demise. Instead, the secondary characters like Medea and her sons who suffer greatly allow the audience to reach catharsis and experience the true suffering, making them the true protagonists in this tragedy.
