What primeval cow was created from the ice in Norse myth?

The primeval cow created from the ice in Norse myth is Auðumbla. She appears at the beginning of the creation story, when the primordial cow and the giant Ymir emerge amid the meeting of fire and ice.

Auðumbla nourishes Ymir with four rivers of milk flowing from her teats. She feeds herself by licking salty, frosted stones. Over three days, her licking reveals Búri: first his hair, then his head, and finally his whole body. Búri becomes the ancestor of Odin and his brothers Vili and Vé.

Auðumbla is attested most fully in Snorri Sturluson’s 13th-century Prose Edda, especially Gylfaginning. Her name has variant manuscript forms, including Auðhumla and Auðumla, and is often interpreted as referring to a rich or hornless cow. She is easily confused with Heiðrún, the goat whose milk or udder supplies mead to Valhalla, but the two belong to different mythic settings.
