Bergelmir (Scand.). The one giant who escaped in a boat the general slaughter of his brothers, the giant Ymir’s children, drowned in the blood of their raging Father. He is the Scandinavian Noah, as he, too, becomes the father of giants after the Deluge. The lays of the Norsemen show the grandsons of the divine Bun—Odin, Wili, and We— conquering and killing the terrible giant Ymir, and creating the world out of his body.
