Horrified at this prophecy, and feeling sure that the King and Queen of Corinth were his parents, and that the oracle's predictions threatened misfortunes to them, OEdipus made up his mind to leave home forever. He did not even dare to return to bid his family good-by, and he started out alone and on foot to seek his fortunes elsewhere. As he walked, he thought of his misfortunes, and grew very bitter against the cruel goddess of fate, whom he had been taught to fear. He fancied that this goddess could rule things as she pleased, and that it was she who had said he would commit the dreadful crimes which he was trying to avoid. After several days' aimless wandering, OEdipus came at last to some crossroads. There he met an old man riding in a chariot, and preceded by a herald, who haughtily bade OEdipus make way for his master. As OEdipus had been brought up as a prince, he was in the habit of seeing everybody make way for him. He therefore proudly refused to stir; and when the herald raised his staff to strike, OEdipus drew his sword and killed him. The old man, indignant at this deed of violence, stepped out of his chariot and attacked OEdipus. Now, the young man did not know that it was his father Laius whom he thus met for the first time, so he fell upon and killed him also. The servants too were all slain when they in turn attacked him; and then OEdipus calmly continued his journey, little suspecting that the first part of the oracle's prediction had been fulfilled. Soon after this fight, OEdipus came to the city of Thebes. The streets were filled with excited people, all talking at once; and the young prince, in listening to what they said, soon learned the cause of their excitement. [Illustration: After a few moments' deep thought, OEdipus answered.] It seems that a terrible monster called the Sphinx had taken up its station on one of the principal roads leading to the town, and would allow no one to pass who could not answer a riddle which it asked. This creature had the head of a woman, the body of a lion, and the wings of an eagle; and, as it ate up all those who could not guess its riddle, the people were very much frightened. Many persons had already been slain; for, although the bravest men had gone out to kill it, they had lost their lives in the attempt, as no one could harm it unless he guessed the mysterious riddle. Laius, the king, hoping to learn from the oracle at Delphi the answer to the riddle, had ridden off in his chariot; but the people grew more excited still, when a messenger came running into the town, and said that the king and all his servants had been killed by robbers, and that their dead bodies had been found in the middle of the road. OEdipus paid no attention to this news; for he little suspected that the old man whom he had killed was the king, whom everybody loved, and for whom they now mourned with noisy grief.
