In the story of Oedipus, a winged monster with the head of a woman and the body of a lion. It waylaid travelers on the roads near the city of Thebes and would kill any of them who could not answer this riddle: “What creatures walk on four legs in the morning, on two legs at noon, and on three legs in the evening?” Oedipus finally gave the correct answer: human beings, who go on all fours as infants, walk upright in maturity, and in old age rely on the “third leg” of a cane.
Note: The sphinx of Greek mythology resembles the sphinx of Egyptian mythology but is distinct from it (the Egyptian sphinx had a man's head). (See under “Fine Arts.”)
