As she sat beside him day after day, Heimdall would tell little Hnossa how all things began. He had lived from the beginning of time and he knew all things. "Before Asgard was built," he said, "and before Odin lived, earth and sea and sky were all mixed together: what was then was the Chasm of Chasms. In the North there was Niflheim, the Place of Deadly Cold. In the South there was Muspelheim, the Land of Fire. In Niflheim there was a cauldron called Hveigelmer that poured out twelve rivers that flowed into the Chasm of Chasms. "Ginnungagap, the Chasm of Chasms, filled up with ice, for the waters of the rivers froze as they poured into it. From Muspelheim came clouds of fire that turned the ice into thick mists. The mists fell down again in drops of dew, and from these drops were formed Ymir, the Ancient Giant. "Ymir, the Ancient Giant, traveled along by the twelve rivers until he came to where another living form was standing in the mists. This was a Giant Cow. Audhumla was the name of that cow. Ymir lay down beside her and drank her milk, and on the milk she gave him he lived. Other beings were formed out of the dew that fell to the ground. They were the Daughters of the Frost, and Ymir, the Ancient Giant, married one, and their children were the Giants. "One day Ymir saw Audhumla breathe upon a cliff of ice and lick with her tongue the place she breathed on. As her tongue went over and over the place he saw that a figure was being formed. It was not like a Giant's form; it was more shapely and more beautiful. A head appeared in the cliff and golden hair fell over the ice. As Ymir looked upon the being that was being formed he hated him for his beauty. "Audhumla, the Giant Cow, went on licking the place where she had breathed. At last a man completely formed stepped from the cliff. Ymir, the Ancient Giant, hated him so much that he would have slain him then and there. But he knew that if he did this, Audhumla would feed him no more with her milk. "Bur was the name of the man who was formed in the ice cliff, Bur, the first of the heroes. He, too, lived on the milk of Audhumla. He married a daughter of the Ancient Giant and he had a son. But Ymir and Ymir's sons hated Bur, and the time came at last when they were able to kill him. "And now there was war between Ymir and Ymir's sons and the son and son's sons of Bur. Odin was the son of Bur's son. Odin brought all his brothers together, and they were able to destroy Ymir and all his brood--all except one. So huge was Ymir that when he was slain his blood poured out in such a mighty flood that his sons were all drowned in it, all except Bergelmir, who was in a boat with his wife when the flood came, and who floated away on the flood to the place that we now call Jötunheim, the Realm of the Giants.
