[the nourishing power ], in Scandinavian mythology, is the cow created by Surt to nourish Ymir. She supplied him with four rivers of milk, and was herself nourished by licking the rocks. (See Ymir.)
Bör, the first man, was made by Audhumla licking salt from the snow. Odin was the son of Bör.
The breath of Audhumla was very sweet, but her milk was bitter.
