Sophocles was an Ancient Greek writer whose works are considered as classics to this day. His tragedies offer insight into the social and political condition of Ancient Greek and often have deep, underlying messages. In one of his best known tragedies, Oedipus the King, Sophocles uses the motif of sight and blindness as a metaphor for insight and knowledge. While the physically blind prophet Tiresias is the only character who has insight, the protagonist, Oedipus, is "blind" to the fact that he has already fallen into his fate. Likewise, Jocasta, the wife of Oedipus, is metaphorically blind to the truth and willing to live in ignorance rather than knowing the truth. Regardless of willingness to accept the truth, Tiresias, Jocasta, and Oedipus ultimately achieve sight which represents knowledge of the truth, paralleling the inevitability of fate.Though physically blind, Tiresias has far more insight and knowledge than the other characters, even knowing the truth about Oedipus' identity. When Oedipus arrives in Corinth, Tiresias recognizes him and refuses to reveal the truth, knowing that truth is harsh. Only when Oedipus mocks him, Tiresias suggests that Oedipus himself is Laius' murderer and the subject of the prophecy.
