“Three roots lie three ways under Yggdrasil's ash: Hel dwells under one, the frost-giants under the second, Page 30mortal men under the third. The squirrel is called Ratatosk who shall run over Yggdrasil's ash; he shall carry down the eagle's words, and tell them to Nidhögg below. There are four harts, with necks thrown back, who gnaw off the shoots.... More serpents lie under Yggdrasil's ash than any one knows. Ofni and Svafni I know will ever gnaw at the tree's twigs. Yggdrasil's ash suffers more hardships than men know: the hart bites above, the side decays, and Nidhögg gnaws below.... Yggdrasil's ash is the best of trees.”

The snake and the tree are familiar in other mythologies, though in most other cases the snake is the protector, while here he is the destroyer. Both Nidhögg and Jörmungandr are examples of the destroying dragon rather than the treasure-guardian. The Ash is the oracle: the judgment-place of the Gods, the dwelling of the Fates, the source of the spring of knowledge. * * * * *

Ragnarök.—The Twilight of the Gods (or Doom of the Gods) is the central point of the Viking religion. The Regin (of which Ragna is genitive plural) are the ruling powers, often called Ginnregin (the great Gods), Uppregin (the high Gods), Thrymregin (the warrior Gods). The word is commonly used of the Aesir in Völuspa; in Alvissmal the Regin seem to be distinguished from both Aesir and Vanir. The whole story of the Aesir is overshadowed by knowledge of this coming doom, the time when they shall meet foes more terrible than the giants, Page 31and fall before them; their constant effort is to learn what will happen then, and to gather their forces together to meet it. The coming Ragnarök is the reason for the existence of Valhalla with its hosts of slain warriors; and of all the Gods, Odin, Thor, Tyr and Loki are most closely connected with it. Two poems of the verse Edda describe it:

(1) Vafthrudnismal:

V. “What is the plain called where Surt and the blessed Gods shall meet in battle?”

O. “Vigrid is the name of the place where Surt and the blessed Gods shall meet in battle. It is a hundred miles every way; it is their destined battle-field.” * * * * *

O. “Whence shall the sun come on the smooth heaven when Fenri has destroyed this one?”

V. “Before Fenri destroy her, the elf-beam shall bear a daughter: that maid shall ride along her mother's paths, when the Gods perish.”

O. “Which of the Aesir shall rule over the realms of the Gods, when Surt's fire is quenched?”

V. “Vidar and Vali shall dwell in the sanctuary of the Gods when Surt's fire is quenched. Modi and Magni shall have Mjöllni at the end of Vingni's (i.e., Thor's) combat.”
