"'The gods assured him that he would easily break a limber silken cord, since he had already burst asunder iron fetters of the most solid construction. "But if thou shouldst not succeed in breaking it," they added, "thou wilt show that thou art too weak to cause the gods any fear, and we will not hesitate to set thee at liberty without delay." "'"I fear me much," replied the wolf, "that if ye once bind me so fast that I shall be unable to free myself by my own efforts, ye will be in no haste to unloose me. Loath am I, therefore, to have this cord wound round me; but in order that ye may not doubt my courage, I will consent, provided one of you put his hand into my mouth as a pledge that ye intend me no deceit." "'The gods wistfully looked at each other, and found that they had only the choice of two evils, until Tyr stepped forward and intrepidly put his right hand between the monster's jaws. Hereupon the gods, having tied up the wolf, he forcibly stretched himself, as he had formerly done, and used all his might to disengage himself, but the more efforts he made, the tighter became the cord, until all the gods, except Tyr, who lost his hand, burst into laughter at the sight. "'When the gods saw that the wolf was effectually bound, they took the chain called Gelgja, which was fixed to the fetter, and drew it through the middle of a large rock named Gjöll, which they sank very deep into the earth; afterwards, to make it still more secure, they fastened the end of the cord to a massive stone called Thviti, which they sank still deeper. The wolf made in vain the most violent efforts to break loose, and, opening his tremendous jaws, endeavored to bite them. The gods, seeing this, thrust a sword into his mouth, which pierced his under jaw up to the hilt, so that the point touched the palate. He then began to howl horribly, and since that time the foam flows continually from his mouth in such abundance that it forms the river called Von. There will he remain until Ragnarök.'" There are also goddesses in the Valhalla, of whom the Edda mentions Frigga, Saga, and many others. § 5. Resemblance of the Scandinavian Mythology to that of Zoroaster.
