In Greco-Roman myths, the Fates, known as the Moirai in Greek tradition and the Norns in Norse culture, play a crucial role in determining an individual's destiny. They are often depicted as three sisters who control the threads of life, weaving the fate of gods and mortals alike. Their involvement signifies the theme of predestination versus free will, highlighting the tension between human actions and an inescapable fate. The Fates’ stories remind us of the limitations of human agency and the acceptance of the life paths predetermined by these powerful entities.
