Ginnungagap (“seeming emptiness”), in the cosmology of Norse mythology, is the primordial void separating Niflheim and Muspell, the land of eternal ice and snow and the land of eternal heat and flame.In the beginning, before the world of men and gods existed, the spring Hvergelmir, deep in the frozen wastes of Niflheim, gave rise to eleven rivers known as the Elivagar. Over a long period of time, water of the Elivagar ran across Niflheim and poured into the northern part of Ginnungagap. The water froze, forming vast sheets of ice in the void. Hot air from Muspell melted some of the ice, creating a zone of meltwater amid the ice and snow. Here life began, and the first living thing was a frost giant.
