In the morning of time, when Asgard and Valhalla were newly built, the gods lived in innocence, happiness and peace. “Glad in their courtyard they played at chess, nor of gold lacked aught”; so runs the description in the Voluspá of this golden age of the Æsir. Then came three mighty Thursar maidens out of Jotunheim, and enmity arose between Æsir and Vanir. One link in the chain of strife was the burning in Valhalla of a woman named Gullveig; “three times they burned the thrice born, again and again- yet still she lives.” The Æsir take counsel together to learn whether peace may still be preserved. Nothing can be done. Odin hurls his spear over the ranks of the enemy, and the first battle of the hosts begins. The walls of the Æsir stronghold are penetrated and the Vanir pour through the breach into Asgard. Yet eventually peace is declared between Æsir and Vanir, the story of which has already been told above. Now the golden age of innocence is at an end; the gods are compelled to defend themselves against their foes, sometimes by the use of guile, as on the occasion when they tricked the Giant mason. Other Giant women — Skadi and Gerd, for example — gain entrance to the dwellings of the Æsir, and Asgard’s sanctity is no more. The season of tranquility gives way to a season of turbulent warfare, in which the gods more than ever before have need of magical weapons, of the aid of Heroes. The gods no longer rule the world as princes of peace; the most eminent of them become gods of war. To this period are to be referred the numerous myths having to do with valorous deeds and guileful practices; and the gods fall far short of always winning victory and glory. Corruption extends from gods to men; the divinities of battle, the Valkyries, ride forth into the world of mortals and here too peace is as a tale that is told.
