Prophecy plays a crucial role in various mythological stories, often serving as a catalyst for events and character actions. Many myths feature prophetic declarations that foreshadow significant outcomes, guiding heroes and influencing destinies. For instance, in Greek mythology, the story of Oedipus is driven by a prophecy that he will kill his father and marry his mother, ultimately leading to his tragic fate. This motif emphasizes themes of free will and inevitability, illustrating how knowledge of the future can shape present decisions and complicate moral outcomes.
