What does Oedipus say about prophecies after hearing news of Polybus' death?

The statement that only fate determines life's path reflects a significant theme in "Oedipus Rex." Oedipus's situation highlights the conflict between free will and predetermined fate. When he learns about Polybus's death, he expresses relief, believing that he has escaped the prophecy that foretold he would kill his father. This moment illustrates Oedipus's misunderstanding of fate; he believes that his actions can change the course of his life, underestimating the power of fate as something that is inescapable.

The play ultimately reveals that, despite Oedipus’s attempts to avoid his fate, the prophecy is fulfilled regardless of his efforts. This aligns with the tragic structure of the story, where fate and destiny play crucial roles. Thus, the assertion that only fate determines life's path captures the essence of Oedipus's journey and the inexorable nature of prophecies in the narrative.
