[Norse] In Norse mythology, Ymir is the primordial giant and the progenitor of the race of frost giants. He was created from the melting ice of Niflheim, when it came in contact with the hot air from Muspell. From Ymir's sleeping body the first giants sprang forth: one of his legs fathered a son on his other leg while from under his armpit a man and women grew out. The frost kept melting and from the drops the divine cow Audumla was created. From her udder flowed four rivers of milk, on which Ymir fed. The cow itself got nourishment by licking hoar frost and salt from the ice. On the evening on the first day the hair of a man appeared, on the second day the whole head and on the third day it became a man, Buri, the first god. His grandchildren are Odin, Ve and Vili. Odin and his brothers had no liking for Ymir, nor for the growing number of giants, and killed him. In the huge amount of blood that flowed from Ymir's wounds all the giants, except two, drowned.

Ymir (Icelandic, Scandinavian) In the Norse creation tale, the primeval frostgiant from whose substance the worlds are formed by the aesir (gods) at the beginning of time. According to the Voluspa (sibyl's prophecy) in the Edda, Ymir was "slain" -- transformed -- by the creative deities Odin Allfather (spirit), Vile (will), and Vi or Ve (awe, sanctity) into the substances that form the worlds in space.
One version relates that sparks from Muspellsheim (realm of fire) fell among the droplets of water vapor in Niflheim (realm of mists or nebulae) creating vapor in Ginnungagap (the yawning void). From this arose the likeness of a man, Ymir, who was nourished by the four streams of milk flowing from the udder of the cow Audhumla -- symbol of fertility. Ymer represents the frozen immobility of non-existence when the universe is not. The Vala (sibyl) relates in Voluspa that the frostgiant's two feet mated with each other and that from them arose all the matter-giants from which all physical creation was formed. She describes poetically how the blood of Ymir became the oceans of water, his bones became mountains, his skull the heavenly vault, but "from his brain were surely all dark skies created." Midgard (central court), the earth, is surrounded and protected by his eyebrows and each quarter of space is governed by one of the four ruling powers, named for the four cardinal points, North, South, East, and West.
