The gods now despaired of ever being able to secure the wolf with any chain of their own making. All-father, however, sent Skirnir, the messenger of the god Frey, into the country of the Black Elves, to the dwarfs, to ask them to make a chain to bind Fenris with. This chain was composed of six things—the noise made by the fall of a cat's foot, the hair of a woman's beard, the roots of stones, the nerves of bears, the breath of fish, and the spittle of birds.
The fetters were as smooth and as soft as silk, and yet, as you will presently see, of great strength. The gods were very thankful for them when they were brought to them, and returned many thanks to him who brought them. Then they took the wolf with them on to the island Lyngvi, which is in the lake Amsvartnir, and there they showed him the chain, desiring him to try his strength in breaking it. At the same time they told him that it was a good deal stronger than it looked. They took it in their own hands and pulled at it, attempting in vain to break it, and then they said to Fenris—
"No one else but you, Fenris, can break it."
"I don't see," replied the wolf, "that I shall gain any glory by breaking such a slight string, but if any artifice has been employed in the making of it, you may be sure, though it looks so fragile, it shall never touch foot of mine."
The gods told him he would easily break so slight a bandage, since he had already broken asunder shackles of iron of the most solid make.
"But," said they, "if you should not be able to break the chain, you are too feeble to cause us any anxiety, and we shall not hesitate to loose you again."
"I very much fear," replied the wolf, "that if you once tie me up so fast that I cannot release myself, you will be in no haste to unloose me. I am, therefore, unwilling to have this cord wound around me; but to show you I am no coward, I will agree to it, but one of you must put his hand in my mouth, as a pledge that you intend me no deceit."
The gods looked on one another wistfully, for they found themselves in an embarrassing position.
Then Tyr stepped forward and bravely put his right hand in the monster's mouth. The gods then tied up the wolf, who forcibly stretched himself, as he had formerly done, and exerted all his powers to disengage himself; but the more efforts he made the tighter he drew the chain about him, and then all the gods, except Tyr, who lost his hand, burst out into laughter at the sight. Seeing that he was so fast tied that he would never be able to get loose again, they took one end of the chain, which was called Gelgja, and having drilled a hole for it, drew it through the middle of a large broad rock, which they sank very deep in the earth. Afterwards, to make all still more secure, they tied the end of the chain, which came through the rock to a great stone called Keviti, which they sank still deeper. The wolf used his utmost power to free himself, and, opening his mouth, tried to bite them. When the gods saw that they took a sword and thrust it into his mouth, so that it entered his under jaw right up to the hilt, and the point reached his palate. He howled in the most terrible manner, and since then the foam has poured from his mouth in such abundance that it forms the river called Von. So the wolf must remain until Ragnarök.
Such a wicked race has Loki begot. The gods would not put the wolf to death because they respected the sanctity of the place, which forbade blood being shed there.
