What news does the messenger from Corinth bring to Oedipus?

The messenger from Corinth brings the news that Polybus, the king of Corinth and Oedipus's supposed father, has died. This information is significant because it gives Oedipus a sense of relief; he believes that the prophecy predicting he would kill his father has been proven false. Oedipus feels vindicated, thinking that he has escaped his fate by leaving Corinth and that the prophecy was misleading. This moment is crucial in the story as it sets the stage for the unraveling of the truth that Oedipus is not who he thinks he is, and that fate is still in play, despite his attempts to evade it.
