Thor goes fishing for the Midgard Serpent in this picture from an
18th century Icelandic manuscript.
'Jörmungandr' , alternately referred to as the 'Midgard Serpent' or 'World Serpent', is a
sea serpent of the
Norse mythology, the middle child of the
giantess Angrboða and the god
Loki.
Overview
According to the
Prose Edda,
Odin took
Loki's three children,
Fenrisúlfr,
Hel and Jörmungandr. He tossed Jörmungandr into the great ocean that encircles
Midgard. The serpent grew so big that he was able to surround the
Earth and grasp his own tail, and as a result he earned the alternate name of the Midgard Serpent or World Serpent. Jörmungandr's arch enemy is the god
Thor.
Stories
There are three preserved myths detailing Thor's encounters with Jörmungandr.
Lifting the cat
In one, Thor encounters the serpent disguised as a colossal cat by the giant king
Útgarða-Loki. As one of the tasks set by Útgarða-Loki, Thor must lift the cat, and though he is unable to lift such a monstrous creature as Jörmungandr, he manages to lift it far enough that it lets go of the ground with one of its four feet. He comes so close that when Jörmungandr is revealed by Útgarða-Loki it is still an impressive deed. This myth is only found in the Prose Edda, although it was adapted for an issue of the Marvel comic book series "Thor" .
Thor's fishing trip
Another encounter came when Thor went fishing with the giant
Hymir. The two did not get along, and when Hymir refused to provide Thor with bait, Thor struck the head off Hymir's largest ox to use as bait. They rowed to a point where Hymir often sat and caught flat fish, and he drew up 100 whales and lions. Thor demanded to go farther, and so they did. Hymir told Thor that the part they were at was unsafe, because of the Serpent, but Thor ignored him, and to Hymir's horror they rowed out further.
Thor then prepared a strong line and a large hook, and Jörmungandr bit. Thor pulled the serpent up; the two faced off, Jörmungandr dribbling poison and blood. Hymir went pale with fear, and as Thor grabbed his hammer to kill the serpent, the giant cut the line, leaving the serpent to sink beneath the waves.
This encounter seems to have been the most popular motif in Norse pagan art. Four picture stones can be definitely linked with the myth.

Thor's foot goes through the boat as he struggles to pull up Jörmungandr in the
Altuna Runestone.
The final battle
Their last meeting will come at
Ragnarök, when Jörmungandr will come out of the ocean and poison the sky. Thor will kill Jörmungandr and then walk nine paces before falling dead from the serpent's poison.
Sources
The major sources for myths about Jörmungandr are the
Prose Edda, ''
Húsdrápa'', ''
Hymiskviða'' and ''
Völuspá''.
Less important sources include
kennings in
skaldic poetry. For example in
Þórsdrápa, ''faðir lögseims'', "father of the sea-thread", is used as a
kenning for Loki.
There are also image stones from ancient times depicting the fishing encounter.
Familiar forms
Jörmungandr is also sometimes referred to as the 'Midgard Serpent' (
Old Norse: Miðgarðsormr) or the 'World Serpent'. His name is sometimes
anglicized as ''Jormungandr'', ''Jormungand'' or ''Iormungand''.
Popular culture
Depictions of and references to Jörmungandr exist in modern popular culture. In
Peter S. Beagle's classic fantasy novel,
The Last Unicorn, a witch casts a spell on a snake to grant it the appearance of Jörmungandr. In addition, the computer game
Starcraft, the Jormungand Brood is one of the principle broods of the
Zerg forces. Additionally, in the playstation videogame
Final Fantasy VII, the protagonist, Cloud Strife, must avoid a great snake called the Midgard Zolom, only to later find it brutally slaughtered by the games main antagonist, Sephiroth.
