In Norse mythology, the mythical one-eyed giant is called Odin. Widely regarded as the chief of the gods, Odin is associated with wisdom, magic, and war. His single eye signifies sacrifice for knowledge; he traded one eye for insight into the mysteries of the cosmos. Odin also embodies the projections of time and fate, overseeing the Valkyries and guiding the slain warriors to Valhalla. His multifaceted character influences various Nordic sagas and legends, representing the complexities of leadership, wisdom, and mortality.
