1. Offers Asylum: Oedipus, accompanied by his daughters Antigone and Ismene, arrives in Colonus seeking shelter. Theseus, the ruler of Athens, welcomes them and offers asylum to Oedipus, even though he knows that harboring a man tainted by fate brings potential curses and dangers to the city.
2. Honors Divine Will: Theseus recognizes that Oedipus is under the protection of the gods, particularly the Furies or Eumenides who pursue him. Theseus believes it is his duty to respect the divine will and offer sanctuary to Oedipus, despite the potential consequences.
3. Provides Safety and Support: Theseus ensures the safety and well-being of Oedipus during his stay in Colonus. He instructs the citizens to treat Oedipus with respect and care, and makes arrangements for his daily needs to be met.
4. Defends Oedipus: When Creon, the ruler of Thebes, arrives to force Oedipus back to Thebes, Theseus intervenes and refuses to hand him over. Theseus argues that Oedipus is under the protection of Athens and cannot be taken against his will.
5. Ensures Peaceful End: Theseus remains true to his word and provides protection to Oedipus until the end of his life. He ensures that Oedipus finds a peaceful and dignified resting place in Colonus, despite opposition from the Thebans and prophecies of divine intervention.
6. Fulfills Prophecies: Theseus's actions in supporting and protecting Oedipus ultimately fulfill the prophecies that Oedipus himself had received and dreaded for years. By aiding Oedipus, he unwillingly brings blessings to Athens, as the presence of Oedipus' grave is said to bring prosperity and protection to the city.
