Step-by-step explanation:
In the story of Oedipus, the opening quotation or line often varies depending on the version or translation being read. However, one possible opening line is:
"Oedipus, once King of Thebes, was the son of Queen Jocasta and King Laius, but he didn't know it."
This opening line is significant to the development of the passage's theme because it sets the stage for the central conflict of the story, which is Oedipus' unwitting fulfillment of a terrible prophecy. The prophecy states that he will kill his father and marry his mother, which he unknowingly does. The theme of fate, or the idea that events are predetermined and unavoidable, is a major theme in the story, and the opening line foreshadows the tragic events that will unfold.
Additionally, the line introduces the idea of Oedipus' ignorance regarding his true identity, which is another important theme in the story. Oedipus spends much of the story attempting to uncover the truth about his past, and his discovery of his own identity leads to his downfall
