This article will explore the origins, powers, and mythology around Jormungandr, one of the most fearsome creatures in Viking tales. Discover how this apocalyptic monster came to be such a prominent part of Norse folklore.

What is Jormungandr?

In Norse myth, Jormungandr is a gargantuan serpent who encircles the earth and seas. Also known as the Midgard Serpent, he is an arch-enemy of Thor often associated with the destructive forces of chaos.

Some key facts about Jormungandr:

  • Enormous snake hundreds of miles long

Origins and History of the Midgard Serpent

The figure of Jormungandr appears prominently in medieval Icelandic and Scandinavian texts compiled by scholars like Snorri Sturluson during the 13th century. But he likely dates back much earlier in Viking folklore and oral tales.

Ancient Beliefs

Ancient Germanic and Norse tribes believed the world was surrounded by serpents and monsters. The ocean that encircled lands and islands was seen as the dominion of a colossal serpent.

Maritime Vikings viewed sea snakes and massive whales as possible incarnations of this being. They saw its coils spanning the entire planet.

Harbinger of Apocalypse

In mythic accounts, Jormungandr is foretold to emerge from the depths before Ragnarok—the apocalyptic battle between gods that ends the world in Norse legend.

Its arrival from the seas was an ill omen signaling the coming cataclysm and the twilight of the gods. Only Thor could oppose it.

Physical Attributes

As a mythical beast, Jormungandr is described as a gigantic serpent often spanning over 100 miles in length. He is typically depicted with:

  • Enormous size large enough to encircle the earth
  • Long, snake-like body with green, black or red scales

  • Fangs dripping with venom
  • Forked tongue flickering from mouth

Habitat and Behavior

Marine Menace

Jormungandr primarily lives deep underwater where sailors passing overhead may glimpse his massive form. From below, he threatens ships and sea creatures alike with his venom and whirlpools.

Coiled around Midgard

But Jormungandr is fated to coil himself around the earth, where his writhing is said to cause earthquakes and tidal waves. Only Thor’s strength can make Jormungandr release the world from his clutches.

Ragnarok’s Harbinger

In myth, Jormungandr bursts forth from the ocean as a harbinger of Ragnarok and floods the earth with venom. This ends Thor and Jormungandr’s legendary feud in mutual destruction.
