In my opinion, I think Teiresias is a very important person in Greek drama because he is the one who can make the stories’ lines float lively. Teiresias is a blind prophet, usually said to have been blinded because he saw the goddess Athena bathing and then to have been awarded the gift of prophecy as a consolation for his blindness.
He is the one after GOD because he has the ability to forecast and can make a hint to the audiences about what will happen in the drama later. He also has the strength to anticipate the truth of something because he can predicts what will happen later in the age.
In Sophocles' Oedipus the King, Oedipus, the king of Thebes, calls upon Tiresias to assist in the investigation of the killing of the previous king Laius. At first, Tiresias refuses to give a direct answer and instead hints that the killer is someone Oedipus really does not wish to find.
However, after being provoked to anger by Oedipus' accusation first that he has no foresight and then that Teiresias replied that Oedipus was the cause of all their problems; this answer almost cost Teiresias his life but Oedipus had sympathy for Teiresias’ age and blindness and throws him out of the palace. Unluckily, Oedipus afterwards realises the truth.
In a nutshell, Teiresias was born with the gift of foretelling. By then, he can make the story more interesting by telling the hints in the conversation. It made the students more understanding about story.
