They relate that Sphinx was a monster, variously formed, having the face and voice of a virgin, the wings of a bird, and the talons of a griffin. She resided on the top of a mountain, near the city Thebes, and also beset the highways. Her manner was to lie in ambush and seize the travellers, and having them in her power, to propose to them certain dark and perplexed riddles, which it was thought she received from the Muses, and if her wretched captives could not solve and interpret these riddles, she, with great cruelty, fell upon them, in their hesitation and confusion, and tore them to pieces. This plague having reigned a long time, the Thebans at length offered their kingdom to the man who could interpret her riddles, there being no other way to subdue her. Œdipus, a penetrating and prudent man, though lame in his feet, excited by so great a reward, accepted the condition, and with a good assurance of mind, cheerfully presented himself before the monster, who directly asked him: “What creature that was, which, being born four-footed, afterwards became two-footed, then three-footed, and lastly four-footed again?” Œdipus, with presence of mind, replied it was man, who, upon his first birth and infant state, crawled upon all fours in endeavoring to walk; but not long after went upright upon his two natural feet; again, in old age walked three-footed, with a stick; and at last, growing decrepit, lay four-footed confined to his bed; and having by this exact solution obtained the victory, he slew the monster, and, laying the carcass upon an ass, led her away in triumph; and upon this he was, according to the agreement, made king of Thebes.
