In Greek mythology, fate is primarily represented through the Moirai or the Fates, three sisters who control the life span and destiny of both humans and gods. They spin, measure, and cut the thread of life, emphasizing the idea that mortals have little power over their destinies. Many myths illustrate characters struggling against or accepting their fates, underscoring a theme that even the mightiest heroes cannot escape their ultimate destiny. The interplay of prophecy and inevitability highlights how fate is both a guiding force and an unyielding constraint in the lives of gods and mortals alike.
