“ On the waters floats the ship Naglfar, which is constructed of the nails of dead men. For which reason great care should be taken to die with pared nails, for he who dies with his nails unpared, supplies materials for the building of this vessel, which both gods and men wish may be finished as late as possible. But in this flood shall Naglfar float, and the giant Hrym be its steersman.
"The wolf Fenrir advancing, opens his enormous mouth; the lower jaw reaches to the earth, and the upper one to heaven, and would in fact reach still farther were there space to admit of it. ”

“ He is the most fearful monster of all, and attacks Tyr, and they kill each other. Thor gains great renown for killing the Midgard serpent, but at the same time, recoiling nine paces, falls dead upon the spot suffocated by the floods of venom which the dying serpent vomits forth upon him. The wolf swallows Odin, but at that instant Vidar advances, and setting his foot on the monster's lower jaw, seizes the other with his hand, and thus tears and rends him till he dies. ”

“ The wolf shall devour the sun, and a severe loss will that be for mankind. The other wolf will take the moon, and this too will cause great mischief. Then the stars shall be hurled from the heavens, and the earth so violently shaken that trees will be torn up by the roots, the tottering mountains tumble headlong from their foundations, and all bonds and fetters be shivered in pieces. Fenrir then breaks loose, and the sea rushes over the earth, on account of the Midgard serpent turning with giant force, and gaining the land. ”
