The Father of Asas and of men had long grey locks and thick curling beard, and he wore a great blue coat flecked with grey like unto the sky when the fleecy clouds scud across it. In his hand he carried a spear, so sacred that, if anyone swore an oath upon its point, that oath could never be broken. On his head he wore, when sitting upon his watch-tower throne, a helmet shaped like an eagle; but when he wandered, as he loved to do, about the earth, he wore a large broad-brimmed hat drawn low over his forehead. Perched on his broad shoulders sat two inky-black ravens, Hugin and Munin, whom every morning he sent to wing their flight about the world that they might see what was going on. Every evening when they returned, they whispered all that they had seen and heard in his ears. At Odin's feet crouched two great wolves, whom he fed from the meat set before him; for he himself cared not to eat flesh-food, and preferred rather to drink the sacred mead provided by the goat who fed upon the leaves of the Tree of Life. Sometimes Odin left his watch-tower throne for the great Council Hall where the twelve Asas sat and took counsel together; but his favourite seat of all was in his own palace of Valhalla, or the Hall of the Chosen Slain. This palace stood in the midst of a wonderful grove of trees, whose leaves were all of red gold, rustling and shimmering in the breeze. Five and forty doors opened into it, each wide enough to allow eight hundred warriors to enter abreast, and over the chief entrance was a boar's head and a great eagle, whose keen gaze looked forth over all the world. The walls of the palace were built of spears of polished steel, so bright that they lighted the whole building; and the roof was made of golden shields. "And wondrous gleamed Valhalla on the heights,-- Her walls shone bright as rows of glittering spears; The roof resplendent like great golden shields; Hundreds of open gates and welcoming doors For myriad warriors from the fields of earth,-- The chosen heroes of the future years, To be great Odin's mighty bodyguard Against the awful prophecies of doom." From end to end of the great hall stood long tables and benches loaded with armour, ready prepared for the fortunate guests. And this was the manner of their selection. Whenever a great battle was about to be fought on the earth, Odin sent forth the nine Valkyrs, or Battle Maidens, his especial attendants, to watch the progress of the fight and to choose from the fallen warriors half of their number. These the Battle Maidens carried on their swift steeds over the Rainbow Bridge into the great hall of Valhalla, where they were welcomed by the sons of Odin and taken to the All-Father's throne to receive his greeting. But if one had shown himself especially heroic in the fight, Odin would descend from his throne and advance to the door to bid him welcome.
