Introduction

According to Norse Mythology, a colossal creature dwells in the ocean. A serpent so large that it encircles the whole of Midgard and bites its own tale. Its name in Old Norse is Jörmungandr (eng. Jormungand or Jormungandr) or Miðgarðsormr (eng. Midgard Serpent or Wyrm).

Its parents are Loki and the giantess Angurboða from Jötunheim. Together they had three children, Jörmungandr the world serpent, the great wolf Fenrir and the queen of the world of the dead Hel. Paternal half-sibling to the three is the eight-legged horse Sleipnir.

When the Aesir gods heard of the birth of the serpent, Fenrir and Hel assembled to discuss the matter. Through prophesying they agreed that great harm and misfortune would come from these siblings. Odin then asked for the siblings to be brought to him. He threw the wyrm into the ocean, but it continued to grow there until it encircled all the lands.

The rivalry between Thor and the Midgard serpent

The god Thor and Midgard serpent have an on going rivalry. In one tale Thor‘s sets out with the jötunn Hymir to catch the wyrm.

They set out to sea on a boat. To lure the monster out, Thor baits it with the head of Hymir‘s largest ox. The monster eventually bites the hook and for a moment they wrestle, until it wriggles free and slips back into the depths of the ocean.

That is not the only time Thor wrestles with the Midgard serpent. In another story, Thor travels to Jötunheim, to the castle Útgarðr. There he meets the ruler Útgarða-Loki. He questions Thor‘s strength and puts him to the test. One of which is to lift his cat. Thor attempts to lift the cat, but it sways and bends so much that only one of its feet leaves the ground. Thor is both furious and baffled. Later it is revealed that trickery was at play in the challenges he faced. When he lifted the cat, it was in reality the Midgard serpent disguised, which Thor was close to lifting.

The Fate of the Midgard Serpent

The rivalry between Thor and Jörmungandr doesn‘t end there. According to the prophecy of Ragnarök, their fates are interwoven when the world falls into chaos. One of the signs of the coming of Ragnarök is a violent turmoil of the ocean when the Midgard serpent releases its tale and makes its way onto land, spewing venom into the water and air. Thor and the Midgard serpent will battle to the death in Ragnarök. Thor kills the serpent but after taking nine paces the god falls himself.
