Sight and blindness
Literal and metaphorical references to eyesight appear throughout Oedipus  the King. Clear vision serves as a metaphor for insight and  knowledge, but  the clear-eyed Oedipus is blind to the truth about his origins and inadvertent  crimes. The prophet Tiresias, on the other hand, although literally blind,  "sees" the truth and relays what is revealed to him. Only after  Oedipus has physically blinded himself does he gain a limited prophetic  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:
