When Tiresias enters the scene, he is a blind old man who needs help to stay on his two feet. He had been summoned by King Oedipus to do as he said and give him answers. But the power completely changes in this scene since Teiresias refuses to answer Oedipus by telling him: “it's better this way, please believe me”. As Oedipus' anger grows, Tiresias' power continues to grow as he continues to challenge his king. Finally, Teiresias loses his composure and shouts to Oedipus: “you are the curse, the corruption of the earth.” At that point, power shifts due to shifting blame and responsibility. It involves Oedipus accusing Tiresias of not telling him anything and ending with Tiresias holding Oedipus responsible for the loss of Thebes. Sophocles used Teiresias to add extra emphasis due to his blindness. How powerful a blind man must be to have to stand up to his powerful king and accuse him of the murder of the man whose throne he took. This image is what makes the character of Tiresias play an even more influential role in the play. This scene between Tiresias and Oedipus is the turning point of the plot and it begins with Oedipus losing his power to Tiresias, the blind.
