Prophetic visions in mythology shape character arcs and decisions, often guiding heroes along their journeys. Characters receiving prophetic insights must navigate a complex interplay of destiny and free will, as seen in stories like that of Oedipus. These visions prompt characters to confront their fates, influencing their actions and relationships with others. The exploration of prophecy reveals deeper themes surrounding knowledge, responsibility, and the impact of choices, ultimately shaping the fabric of the narrative and illustrating the consequences of heeding or ignoring prophetic messages.
