How did Oedipus Rex become King of Thebes?
On the road to Thebes, he meets Laius, his true father. Unaware of each other’s identities, they quarrel over whose chariot has right-of-way. Oedipus’s pride leads him to murder Laius, fulfilling part of the oracle’s prophecy. Shortly after, he solves the riddle of the Sphinx, which has baffled many a diviner: “What is the creature that walks on four legs in the morning, two legs at noon, and three in the evening?” To this Oedipus replies, “Man” (who crawls on all fours as a baby, walks upright later, and needs a walking stick in old age), and the distraught Sphinx throws herself off the cliffside. Oedipus’s reward for freeing the kingdom of Thebes from her curse is the kingship and the hand of queen Jocasta, his biological mother. The prophecy is thus fulfilled, although none of the main role players know it.
