Three beautiful but evil-disposed maidens arrived at Asgard from the giants' world, Jotunheim, by whom confusion and ill-will were spread over the world. Then the gods determined to create new beings to people the universe. They gave human bodies and understanding to dwarfs, who had been generated within the dead body of Ymir, and who took up their abodes in the bowels of the earth, in rocks, in stones, and in trees and flowers. Then Odin, with two companions, went forth on an excursion to the earth, and created a man and woman; and from this pair, whose abode was at Midgard, the human race sprang. A bridge of various colours, known to men as the rainbow, connected Midgard with Asgard, and over this the gods rode daily to a sacred fountain. This fountain lay at one of the three roots of the ash Yggdrasil, whose branches spread over the whole earth and reached above the heavens. Under one of these roots was the abode of Hel, the goddess of the dead, under another that of the frost giants, and under the third was the dwelling of human beings. Baldur dreamt evil dreams of threatened danger to his life. He related them to the gods, who endeavoured to protect him from injury. Frigga made fire, water, iron, and all metals, stones, earth, plants, beasts, birds, serpents, poison, and all diseases, swear that they would not hurt Baldur. Loki was displeased at this. He changed himself into the form of an old woman, and, inquiring the cause of Baldur's invulnerability, was told by Frigga that all things, animate and inanimate, had sworn not to harm him, with the exception of one little shrub, the misletoe. Loki, rejoicing at the information he had received, procured this little shrub, and hastened with it to an assembly of the gods, where he placed it in the hands of the blind Hoder, the god of war, who cast it at Baldur, and pierced him to the heart. Hermoder, the son of Odin, offered to proceed to Hel to release Baldur; and Hel, on hearing the request made, consented to let him go, on condition that all things would weep for Baldur. All men, all living beings, and all things wept except the witch Thock, who refused to mourn for the departed god. Baldur was therefore compelled to remain in Hel, where he will be to the end of the world. Loki was beautiful, and possessed of great knowledge and cunning. He often brought the gods into trouble, from which, however, through his craft he extricated them. Hence he was regarded as the Evil Spirit. Sometimes he was called Asa-Loki, to distinguish him from Utgarda-Loki, a king of the giants, whose kingdom lay at the uttermost limits of the earth.
