Audumla (Scand.). The symbol of nature in the Norse mythology; the cow who licks the salt rock, whence the divine Buri is born, before man’s creation.
Audumla (Scand.) The Cow of Creation, the “nourisher”, from which flowed four streams of milk which fed the giant Ymir or Örgelmir (matter in ebullition) and his sons, the Hrimthurses (Frost giants), before the appearance of gods or men. Having nothing to graze upon she licked the salt of the ice-rocks and thus produced Buri, “the Producer” in his turn, who had a son Bör (the born) who married a daughter of the Frost Giants, and had three sons, Odin (Spirit), Wili (Will), and We (Holy). The meaning of the allegory is evident. It is the precosmic union of the elements, of Spirit, or the creative Force, with Matter, cooled and still seething, which it forms in accordance with universal Will. Then the Ases, “the pillars and supports of the World” (Cosmocratores), step in and create as All-father wills them.
