The origin of the Hrim Thursar and the Birth of Ymir, who lived in Ginnungagap, and of Odin, Vili, and Ve, is as follows: “Gangleri asked, ‘How was it before the kindreds existed and mankind increased?’ Hár answered, ‘When the rivers called Elivagar had run so far from their sources that the quick venom which flowed into them, like the dross which runs out of the fire, got hard, and changed into ice; when this ice stood still and flowed no longer, the exhalation of the poison came over it and froze into rime; the rime rose up all the way into the Ginnungagap.’ Jafnhár said, ‘The part of Ginnungagap turning to the north was filled with the heaviness and weight of ice and rime, and the opposite side with drizzle and gusts of wind; but the southern part of Ginnungagap became less heavy, from the sparks and glowing substances which came flying from Muspelheim.’ Thridi said, ‘Just as the cold and all things come from Niflheim, the things near Muspel were hot and shining; Ginnungagap was as warm as windless air. When the rime and the breath of the heat met so that the rime melted into drops, a human form came from these flowing drops with the power of the one who had sent the heat; he was called Ymir, but the Hrimthursar call him Örgelmir, and the kin of the Hrimthursar have sprung from him.’ Gangleri asked, ‘How did the kin grow from this, or how came it that there were more men; or dost thou believe in the god of whom thou didst tell now?’ Hár answered, ‘By no means do we think him a god; he was bad, and all his kinsmen; we call them Hrimthursar. It is told that when asleep he sweated, and then there grew a man and a woman from under his left arm, and one of his feet begot a son with the other; thence have sprung the kin of Hrimthursar. We call Ymir the Old Hrimthurs.’ “Gangleri asked, ‘Where did Ymir live, or by what?’ ‘It happened next when the hoar-frost fell in drops that the cow Audhumla grew out of it; four rivers of milk ran from her teats, and she fed Ymir.’ “Gangleri asked, ‘On what did the cow feed?’ Hár answered, ‘She licked the rime-stones covered with salt and rime, and the first day when she licked them a man’s hair came out of them in the evening; the second day a man’s head; the third day a whole man was there; he is called Buri; he was handsome in looks, large, and mighty; he had Bör for son, who got Besla, daughter of Bölthorn jötun, for wife, and she had three sons, Odin, Vili,[28] Ve; and it is my belief that this Odin and his brothers are the rulers of heaven and earth. We think he is called so. Thus the man whom we know to be the greatest and most famous is called, and they may well give him this name’” (‘Gylfaginning,’ c. 5). The ash tree Yggdrasil is one of the strangest conceptions found in any mythology.
