First of all they built a house with a silver roof, where there were seats for all the twelve chiefs. In the midst, and high above the rest, was the wonder-throne of Odin the All-Father, whence he could see everything that happened in the sky or on the earth or in the sea. Next they made a fair house for Queen Frigg and her lovely daughters. Then they built a smithy, with its great hammers, tongs, anvils, and bellows, where the gods could work at their favorite trade, the making of beautiful things out of gold; which they did so well that folk name that time the Golden Age. Afterwards, as they had more leisure, they built separate houses for all the Æsir, each more beautiful than the preceding, for of course they were continually growing more skillful. They saved Father Odin's palace until the last, for they meant this to be the largest and the most splendid of all. Gladsheim, the home of joy, was the name of Odin's house, and it was built all of gold, set in the midst of a wood whereof the trees had leaves of ruddy gold,--like an autumn-gilded forest. For the safety of All-Father it was surrounded by a roaring river and by a high picket fence; and there was a great courtyard within. The glory of Gladsheim was its wondrous hall, radiant with gold, the most lovely room that time has ever seen. Valhalla, the Hall of Heroes, was the name of it, and it was roofed with the mighty shields of warriors. The ceiling was made of interlacing spears, and there was a portal at the west end before which hung a great gray wolf, while over him a fierce eagle hovered. The hall was so huge that it had 540 gates, through each of which 800 men could march abreast. Indeed, there needed to be room, for this was the hall where every morning Odin received all the brave warriors who had died in battle on the earth below; and there were many heroes in those days. This was the reward which the gods gave to courage. When a hero had gloriously lost his life, the Valkyries, the nine warrior daughters of Odin, brought his body up to Valhalla on their white horses that gallop the clouds. There they lived forever after in happiness, enjoying the things that they had most loved upon earth. Every morning they armed themselves and went out to fight with one another in the great courtyard. It was a wondrous game, wondrously played. No matter how often a hero was killed, he became alive again in time to return perfectly well to Valhalla, where he ate a delicious breakfast with the Æsir; while the beautiful Valkyries who had first brought him thither waited at table and poured the blessed mead, which only the immortal taste. A happy life it was for the heroes, and a happy life for all who dwelt in Asgard; for this was before trouble had come among the gods, following the mischief of Loki.
