Oedipus Rex reveals the prophecy which caused him to leave Corinth (791-93): "that I was fated to lie with my mother," "and show to daylight an accursed breed" "which men would not endure, and I was doomed" "to be murderer of the father that begot me." The implication of Laius's oracle is ambiguous. One interpretation considers that the presentation of Laius's oracle in this play differs from that found in Aeschylus's Oedipus trilogy produced in 467 BC. Helaine Smith argues: Sophocles had the option of making the oracle to Laius conditional ("if" Laius has a son, that son will kill him) or
Oedipus Rex ability, as seen in "Oedipus at Colonus". It is deliberately ironic that the "seer" can "see" better than Oedipus, despite being blind. In one line (Oedipus the king, 469), Tiresias says: ""So, you mock my blindness? Let me tell you this. You [Oedipus] with your precious eyes, you're blind to the corruption of your life ..."" (Robert Fagles 1984) Sigmund Freud in "Interpretation of Dreams" wrote a notable passage regarding of the destiny of Oedipus as well as the Oedipus complex. He analyzes why this play, "Oedipus Rex", written in Ancient Greece, is so effective even to a modern audience.
