But at last, during one sunrise, a wolf came out of Jarnvid, and began to howl at the sun. The sun did not seem to heed him, but walked majestically up the sky to her mid-day point; then the wolf began to run after her, and chased her down the sky again to the low west. There the sun opened her bright eye wide, and turned round at bay; but the wolf came close up to her, and opened his mouth, and swallowed her up. The earth shuddered, and the moon rose. Another wolf was waiting for the moon with wide jaws open, and, while yet pale and young, he, too, was devoured. The earth shuddered again; it was covered with cold and darkness, while frost and snow came driving from the four corners of heaven. Winter and night, winter and night, there was now nothing but winter. A dauntless eagle sat upon the height of the Giantess' Rock, and began to strike his harp. Then a light red cock crowed over the Bird Wood. A gold-combed cock crowed over Asgard, and over Helheim a cock of sooty red. From a long way underground Garm began to howl, and at last Fenrir broke loose from his rock-prison, and ran forth over the whole earth. Then brother contended with brother, and war had no bounds. A hard age was that. "An axe age, A sword age, Shields oft cleft in twain; A storm age, A wolf age, Ere the earth met its doom." Confusion rioted in the darkness. At length Heimdall ran up Bifröst, and blew his Giallar horn, whose sound went out into all worlds, and Yggdrasil, the mighty ash, was shaken from its root to its summit. After this Odin saw himself ride forth from Asgard to consult Mimer at the Well of Wisdom. Whilst he was there Jörmungand turned mightily in his place, and began to plough the ocean, which caused it to swell over every shore, so that the world was covered with water to the base of its high hills. Then the ship Naglfar was seen coming over the sea with its prow from the east, and the giant Hrym was the steersman.
