The moment of epiphany comes late in the play. At the beginning of Scene III, Oedipus is still waiting for the servant to be brought into the city, when a messenger arrives from Corinth to declare that King Polybus of Corinth is dead. Oedipus, when he hears this news, feels much relieved, because he believed that Polybus was the father whom the oracle had destined him to murder, and he momentarily believes himself to have escaped fate. He tells this all to the present company, including the messenger, but the messenger knows that it is not true. He is the man who found Oedipus as a baby in the pass of Cithaeron and gave him to King Polybus to raise. He reveals, furthermore that the servant who is being brought to the city as they speak is the very same man who took Oedipus up into the mountains as a baby. Jocasta realizes now all that has happened. She begs Oedipus not to pursue the matter further. He refuses, and she withdraws into the palace as the servant is arriving. The old man arrives, and it is clear at once that he knows everything. At the behest of Oedipus, he tells it all.

Translator Lattimore renders kleos aphthiton as forever immortal and as forever imperishable —connoting Achilles's mortality by underscoring his greater reward in returning to battle Troy.
