You child of endless night! You can hurt me Or any other man who sees the sun.
True: it is not from me your fate will come. That lies within Apollo's competence.
Scene 3: Oedipus and Iocaste
I will not listen; the truth must be made known.
Listen to me, I beg you: do not do this thing!
Exodus: Choragos and Second Messanger
We have enough grief already. What new sorrow do you mean?
The greatest griefs are the one we cause ourserlves.
The Queen is dead.
In his arrogance, Oedipus curses Teiresias for speaking the truth, but as Teiresias reminds him, only gods can control fate. Oedipus's arrogance, his belief that he could defy prophecy, is what led to his demise.
Iocaste, knowing the truth about her son, pleads Oedipus to cease asking questions, but in his determination to learn about his origins, Oedipus thoughtlessly dismisses his wife and, thus, seals his fate.
After the truth of Oedipus's birth is revealed, a messenger informs the Choragos that Iocaste killed herself. The messenger's comment on grief holds true. In his arrogance, Oedipus caused all of this. In the end, Oedipus's nemesis wasn't Teiresias or Iocaste; it was fate itself.
