The Sphinx and Oedipus

Greece Myth Riddle Fate Cunning

A Sphinx terrorizes Thebes with a riddle. Oedipus answers “man,” prompting the Sphinx’s death and his rise as king—beginning a tragic fate already foretold.

Story beats

  1. 1) The Sphinx—lion body, woman’s head, wings—blocks Thebes, killing those who fail her riddle.
  2. 2) “What walks on four legs in morning, two at noon, three in evening?” Oedipus answers: human life stages.
  3. 3) The Sphinx dies (leaps or turns to stone). Thebes crowns Oedipus, giving him Jocasta as wife.
  4. 4) The victory triggers the deeper tragedy: he fulfills the prophecy of killing his father and marrying his mother.

Context & symbolism

The Sphinx episode showcases intellect defeating brute menace. The riddle maps human lifecycle; Oedipus’ insight contrasts his ignorance of his own identity. Solving the riddle wins kingship but also locks in doom—fate’s double edge.

The Sphinx, a foreign monster from Ares/Hera lore, marks a liminal test before the main tragedy unfolds.
