In Norse mythology, Ymir (), also called Aurgelmir, Brimir, or Bláinn, is the ancestor of all jötnar. Ymir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional material, in the Prose Edda, written by Snorri Sturluson in the 13th century, and in the poetry of skalds. Taken together, several stanzas from four poems collected in the Poetic Edda refer to Ymir as a primeval being who was born from atter (), yeasty venom that dripped from the icy rivers called the Élivágar, and lived in the grassless void of Ginnungagap. Ymir gave birth to a male and female from his armpits, and his legs together begat a six-headed being. The grandsons of Búri, the gods Odin and Vili and Vé, fashioned the Earth—elsewhere personified as a goddess named Jörð—from Ymir's flesh; the oceans from his blood; from his bones, the mountains; from his hair, the trees; from his brains, the clouds; from his skull, the heavens; and from his eyebrows, the middle realm in which humankind lives, Midgard. In addition, one stanza relates that the dwarfs were given life by the gods from Ymir's flesh and blood (or the Earth and sea).
