How did the concept of fate differ between Norse and Greek mythology?

Both Norse and Greek mythologies possess complex understandings of fate that play a crucial role in their respective narratives, yet they embody distinct characteristics reflective of their cultural philosophies. In Greek mythology, Moirai, or the Fates, are depicted as three sisters who control the destiny of gods and mortals alike, weaving the fabric of life with strict precision. Meanwhile, in Norse mythology, the concept of fate is embodied by the Norns, who also number three and dwell by Yggdrasil, the World Tree, shaping destiny but allowing for more interplay between free will and foretold outcomes. By comparing these mythological frameworks, one can gain deeper insights into how each culture perceived the tension between predestination and autonomy.
