son of Laius and Jocasta, the king and queen of Thebes, Greek, literally "swollen-foot," from oidan "to swell" (from PIE *oid-; see edema) + pous (genitive podos) "foot" (see foot (n.)). Oedipus complex (1910) coined by Freud. In Latin, figurative references to Oedipus generally referred to solving riddles. Oedipus effect (1957) is Karl Popper's term for "the self-fulfilling nature of prophecies or predictions."
In classical mythology, a tragic king who unknowingly killed his father and married his mother. The Delphic oracle predicted that King Laius of Thebes, a city in Greece, would be killed by his own son. To save himself, Laius ordered his newborn son placed on a mountaintop and left to starve. The infant was rescued by a shepherd and raised in a distant city, where he was given the name Oedipus. Years later, King Laius was killed while on a journey by a stranger with whom he quarreled. Oedipus arrived at Thebes shortly thereafter and saved the city from the ravages of the Sphinx. He was proclaimed king in Laius' stead, and he took the dead king's widow, Jocasta, as his own wife.
After several years a terrible plague struck Thebes. The Delphic oracle told Oedipus that to end the plague, he must find and punish the murderer of King Laius. In the course of his investigation, Oedipus discovered that he himself was the killer and that Laius had been his real father. He had therefore murdered his father and married his mother, Jocasta. In his despair at this discovery, Oedipus blinded himself.
Note: The story of Oedipus is the subject of the play Oedipus Rex by Sophocles.
Note: The Oedipus complex, identified by the psychoanalyst Sigmund Freud, takes its name from the story of Oedipus.
