Sphinx

Sphinx, The A monster having the head and breast of a woman, the body of a dog, the tail of a serpent, the wings of a bird, the paws of a lion, and a human voice. She lived in the country near Thebes, and proposed to every passer-by the following enigma: “What animal is that which walks on four legs in the morning, two at noon, and three in the evening.” Oedipus solved the riddle thus: Man is the animal; for, when an infant he crawls on his hands and feet, in the noontide of life he walks erect, and as the evening of his existence sets in, he supports himself with a stick. When the Sphinx found her riddle solved she destroyed herself.
