The plot is rather intricate and must be given at greater length. The scene shows the palace of Œdipus at Thebes. The people are smitten by a pestilence; and all look to the king, who has already sent his wife’s brother, Creon, to ask advice from the Delphic oracle. Creon enters, bringing tidings that Thebes will be freed if the city is purged of those who killed Laius, the former king. Œdipus asks for particulars, and learns that Laius was killed by some robbers. Only one man escaped. The king calls upon the slayer to declare himself, promising no worse treatment than exile; he asks also any man who knows the guilty one to speak. If no one confesses, he denounces civil and religious excommunication against the unknown. The chorus-leader suggests that the prophet Tiresias should be consulted; Œdipus replies that he has been already summoned. The coryphæus remarks casually that some say Laius was slain by certain wayfarers. Tiresias enters, but shows a repugnance even to discuss the problem, till Œdipus in a rage accuses Tiresias of complicity in the murder. An altercation follows in which the prophet accuses Œdipus of having killed Laius. The other, filled with wrath, proclaims that Tiresias and Creon are plotting to make Creon king in his stead. Tiresias threatens the king with mysterious horrors and downfall. Œdipus bids him begone, and rates him for a fool. “Foolish, perhaps, in your eyes,” says the old man, “but thought wise by the parents that begat thee.” Œdipus is startled. “Parents? Stay! What man begat me?” The answer is: “This day shall show thy birth and thy destruction”. The king again bids him go. As he turns away, Tiresias utters his farewell speech. The murderer of Laius is here, supposed an alien, but in reality Theban-born. Bereft of his sight and his riches he shall go forth into a strange land, and shall be found brother and father of his children, son and husband of his wife, murderer and supplanter of his father. Creon enters, dismayed by the charges of Œdipus, when the king appears, heaps reproaches upon the supposed traitor, and insists that Creon shall die. The noise of their dispute brings from the palace Jocasta, sister of Creon and wife of Œdipus; she brings about a half-reconciliation between the two princes, and asks the cause of the quarrel. Œdipus tells of the accusation pointed at himself by Tiresias. Jocasta seeks to console him by a proof that soothsaying is not trustworthy. “An oracle once came to Laius that he should be slain by a son of his and mine. None the less, he was slain by foreign robbers at a place where three roads meet; and the child, not three days old, was cast out upon a mountain, his ankles yoked together.” This speech, so far from comforting the king, fills him with alarm. The phrase “a place where three roads meet” has struck him. He anxiously asks for a description of Laius and the number of his followers. The replies disturb him still more, and he asks that the
