character of tiresias?

Teiresias is the blind prophet, led by a small boy, who knows the truth about Oedipus's parentage. Oedipus calls on him to find Laius's killer but becomes furious when Teiresias claims that Oedipus himself is the killer. Teiresias's words, however, prove true ultimately, suggesting that he is a mouthpiece for the Gods and an oracle to be trusted far more than the convictions and hopes of man. Teiresias is often represented as being part-male, part-female in classical literature.

In Oedipus The king, Teiresias is the blind prophet serving as the voice of destiny. In him is embodied the contradiction between eyesight and spiritual insight.
