And in time the heroes died, all but Nestor the silver-tongued old man; and left behind them valiant sons, but not so great as they had been. Yet their fame, too, lives till this day; for they fought at the ten years' siege of Troy; and their story is in the book which we call Homer, in two of the noblest songs on earth; the Iliad, which tells us of the siege of Troy, and Achilles's quarrel with the kings; and the Odyssey, which tells the wanderings of Odysseus, through many lands for many years; and how Alcinous sent him home at last, safe to Ithaca his beloved island, and to Penelope his faithful wife, and Telemachus his son, and Euphorbus the noble swineherd, and the old dog who licked his hand and died. CHAPTER XI THE GIANT BUILDER Ages and ages ago, when the world was first made, the gods decided to build a beautiful city high above the heavens, the most glorious and wonderful city that ever was known. Asgard was to be its name, and it was to stand on Ida Plain under the shade of Yggdrasil, the great tree whose roots were underneath the earth. 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 favourite trade, the making of beautiful things out of gold; which they did so well that folk name that time the Golden Age. Afterward, 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 skilful. 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.
