In Greek tragedy and mythology, fate plays a pivotal role, often depicted as an inescapable force that governs the lives of mortals. The concept of Moira represents the predetermined destiny each individual must face, highlighting the tension between free will and destiny. Tragic heroes such as Oedipus grapple with prophecy and their attempts to sidestep fate, only to find that their efforts lead to their downfalls. This theme underscores the Greeks' belief in the limits of human agency and the overarching power of fate in shaping human existence.
