Oedipus Rex unconditional (Laius "will" have a son who will kill him). Both Aeschylus and Euripides write plays in which the oracle is conditional; Sophocles ... chooses to make Laius's oracle unconditional and thus removes culpability for his sins from Oedipus, for he could not have done other than what he did, no matter what action he took. This interpretation is supported by Jocasta's repetition of the oracle at lines 854–55: "Loxias declared that the king should be killed by/ his own son." In the Greek, Jocasta uses the verb "chrênai": "to be fated, necessary." This iteration of the oracle seems to
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.
