When the attendants came hurrying to the king's assistance, they were horrified at finding both him and his charioteer dead; but although they searched everywhere, no trace of the murderer could be found. Œdipus meanwhile had escaped and was on his way to Thebes, whither the servants were now preparing to carry their dead master. Though strangers were usually noticed as they came through the city gates, Œdipus was scarcely observed during the many days that Thebes was in mourning for the dead king. When the funeral ceremonies were over, the young stranger heard one day a herald proclaiming in the streets that the throne of Thebes should belong to him who could kill the Sphinx and thus free the country from its baneful presence. The hand of the queen Jocasta was also promised as a further reward. When Œdipus asked one of the natives what this creature called the Sphinx might be, the old man to whom he spoke turned on him a look of surprise, and remarked that he must indeed be a stranger to Thebes if he did not know that the city was suffering from the presence of the Sphinx.

So, sword in hand, he went out of the city gates, and walked boldly along the road to the rock where the crouching Sphinx lay in wait for its prey. As soon as it saw Œdipus, it stopped him, and demanded that he should answer the riddle or else lose his life. "Tell me your riddle then," cried the hero, boldly; and the Sphinx replied:-- "What is it that in the morning goes on four feet, at noon on two feet, and in the evening upon three?" For some minutes Œdipus did not answer, but he crept nearer to the Sphinx, with his sword gripped firmly in his hand. The monster began to lick its cruel lips, and stretch out one long claw toward its victim, when Œdipus answered:--
