the curious, somnolent first man, Ymir, of the Icelandic Eddas, who took form in the 'yawning void' of the beginning... Ymir's great somnolent body then was cut up to form the world: Of Ymir's flesh the earth was fashioned, And of his sweat the sea; Crags of his bones, trees of his hair, And of his skull the sky.
Campbell presents Ymir as the Norse instantiation of the universal primordial-victim mythologem, in which the cosmic body of the first being is sacrificed and distributed to become the material constituents of the world.
