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.
And now, seated at the long tables, loaded with great beakers of mead and dishes of boar flesh, the warriors feasted merrily, tended by the fair Battle Maidens.
"The blazing roof resounds The genial uproar of those shades who fall In desperate fight, or by some brave attempt."
When they had eaten all they could, the warriors would call for their weapons, ride out into the great courtyard, and there wage desperate fights, in the course of which many a man would be sorely wounded. But this mattered little, for at the sound of the dinner horn all wounds were healed.
"And all day long they there are hacked and hewn 'Mid dust, and groans, and limbs lopped off, and blood But all at night return to Odin's hall Woundless and fresh; such lot is theirs in heaven."
These warriors were Odin's special joy and delight, and he was never weary of watching them at feast or in the combat. Sometimes, indeed, when some battle on earth was impending, he would appear, riding upon his eight-footed grey horse, and with white shield on arm would fling his glittering spear into the ranks of the warriors as signal for the fight to begin, and would rush into the fray with his war-cry, "Odin has you all!"
Now, though all this shows very clearly that All-Father Odin was a warlike Asa and delighted in battles, there was another side to his character, for beyond all the other Asas he cared for wisdom.
Very early in the morn of time All-Father Odin discovered that beneath the roots of the Tree of Life, just where sky and ocean met, there was a marvellous spring of water, "the fountain of all wit and wisdom." Looking into its crystal depths, all that was going to happen in the future was revealed, and anyone drinking of it received the gifts of wisdom, knowledge, and right judgment about all things. Now this spring was guarded by the Giant Mimir, who prided himself upon being wiser than any other giants or Asas could be, for he alone had the right to draw water from the well; and every morning, dipping his glittering horn therein, he drank a long draught, and with every draught he grew wiser, till he knew everything that was past and present and is to come.
