Oedipus Rex, by the Greek playwright Sophocles, is, without a doubt, one of the greatest examples of dramatic irony. There are many instances where the audience knows so much more than the main characters, and Sophocles uses irony to point to Oedipus as Laius' murderer as well. Additionally, Oedipus is most definitely a tragic hero-he had a tragic flaw, namely that he was relentless and often rash in his search for the truth about Laius' death and his killer; this ultimately lead to Oedipus' own destruction. He also refuses to compromise or humble himself before others and stubbornly refuses to allow others to express different opinions from their own. Oedipus is so arrogant and self-confident that he challenges the will of the gods (hence, the entire basis of the play).One of the early examples of dramatic irony in the play is during the scene in which Oedipus accuses Creon of plotting against him with Teiresias, an old, blind prophet.

To contribute to the irony, Oedipus curses Laius' murderer and vows to avenge the former king's death. He is virtually condemning himself. His speeches foreshadow his imminent doom- he is destined by the...
