Oedipus Rex

I met a girl named Cassandra in my economics class and when she saw the book "Greek Tragedy" on my desk, she got excited and start telling me how much she loves stories in the book. She told me Oedipus Rex was her favorite story. Thus, I wondered what is good about this story? At first, this story reminded me, Shakespear's Hamlet when the father who is king, was destined to be murdered by his own son and therefore abondon his son to far-far away as if Laius sent his son to a shepherd fearing the prophency. Ironically, the child ended up in the hand of king Polybus and Queen Merope who were childless themselves. He was named Oedipus. Oedipus later learns about his orables and avoid himself returning to Corinth. Unfortunately, by his misunderstanding of the oracles, he ventured to Thebes and killed Laius without realizing his as the king of Thebes nor as his birth father. Interestingly, I thought Sphinx is an Egyptian figure but also make its appearance in Greek Tragedy. Later on, Oedipus becomes a king by marrying widowed Queen, Jocasta. Tragedically, Laius' actions tried to avoid the oracles have led to the success of the oracle.
