The Tree Yggdrasil
Allfather next created a huge ash called Yggdrasil, the tree of the universe, of time, or of life, which filled all the world, taking root not only in the remotest depths of Nifl-heim, where bubbled the spring Hvergelmir, [13]but also in Midgard, near Mimir’s well (the ocean), and in Asgard, near the Urdar fountain.
From its three great roots the tree attained such a marvellous height that its topmost bough, called Lerad (the peace-giver), overshadowed Odin’s hall, while the other wide-spreading branches towered over the other worlds. An eagle was perched on the bough Lerad, and between his eyes sat the falcon Vedfolnir, sending his piercing glances down into heaven, earth, and Nifl-heim, and reporting all that he saw.
As the tree Yggdrasil was ever green, its leaves never withering, it served as pasture-ground not only for Odin’s goat Heidrun, which supplied the heavenly mead, the drink of the gods, but also for the stags Dain, Dvalin, Duneyr, and Durathor, from whose horns honey-dew dropped down upon the earth and furnished the water for all the rivers in the world.
In the seething cauldron Hvergelmir, close by the great tree, a horrible dragon, called Nidhug, continually gnawed the roots, and was helped in his work of destruction by countless worms, whose aim it was to kill the tree, knowing that its death would be the signal for the downfall of the gods.
“Through all our life a tempter prowls malignant,
The cruel Nidhug from the world below.
He hates that asa-light whose rays benignant
On th’ hero’s brow and glitt’ring sword bright glow.”
Viking Tales of the North (R. B. Anderson).
Scampering continually up and down the branches and trunk of the tree, the squirrel Ratatosk (branch-borer), the typical busybody and tale-bearer, passed its time repeating to the dragon below the remarks of the eagle above, and vice versa, in the hope of stirring up strife between them.
