Marvel did not invent Thor. The real thor norse god is older, stranger, and a good deal less clean-shaven than Chris Hemsworth — a red-bearded protector of Midgard whose hammer, goats, and short temper made him the most personally worshipped god of the Viking Age. More Mjolnir pendants and men named Thorstein or Thorvald turn up in the archaeological record than for any other Norse deity.

This guide sticks to what the Eddas actually say: his gear, his goats, the one giant who out-thought him, and how he actually dies.

Thor in the Eddas vs. the Marvel Thor

In the medieval sources, Thor is the son of Odin and Jörð, the earth herself — not a golden prince waiting to inherit a throne, but a working god. He is imagined as thickset and red-bearded, quick to anger, and endlessly useful: he is the one who rides out to Jötunheim to keep giants from overrunning Asgard and Midgard. Norse farmers and sailors, who had little use for Odin’s battlefield poetry or Loki’s schemes, carved his hammer onto their arm rings and wore it around their necks as a Christian cross’s pagan counterpart.

The film version keeps the hammer and the temper but drops almost everything else: the goats, the giants he loses to, and the fact that in the sagas he is usually the down-to-earth muscle, not the heir to a cosmic kingdom.

Mjölnir, Jarngreipr and Megingjörð: Thor’s Three Treasures

Thor rarely fights alone — he fights with a full kit. Mjölnir, his hammer, was forged by the dwarf brothers Brokkr and Sindri after Loki wagered his own head that they couldn’t out-craft the sons of Ivaldi. Loki, worried he’d lose the bet, turned into a fly and bit Brokkr while he worked the bellows, which is why the finished handle came out shorter than intended. The gods judged it the greatest gift anyway, since nothing could stop the Aesir’s enemies like a hammer that always finds its mark and always returns to the thrower’s hand.

Two more items make Mjölnir usable at all. Jarngreipr, a pair of iron gauntlets, are needed just to grip the hammer’s short shaft, and Megingjörð, a belt of strength, doubles Thor’s already considerable power when he buckles it on. Together the three form a complete loadout that shows up constantly in Viking-Age jewelry — if you want the fuller rundown of what Mjölnir and its companion emblems mean today, our Norse symbols guide covers the whole set.

Tanngrisnir and Tanngnjóstr: The Goats That Pull His Chariot

Thor doesn’t ride a horse — he drives a cart across the sky pulled by two goats, Tanngrisnir (“teeth-barer”) and Tanngnjóstr (“teeth-grinder”). Norse folklore treated the rumble of their cart wheels as the literal sound of thunder. The goats have one more trick: Thor can slaughter and eat them for dinner, then resurrect them whole the next morning with a tap of Mjölnir, as long as none of their bones were broken or split for the marrow.

The Journey to Utgarda-Loki: When Thor Was Outsmarted

Not every story is a Thor win. On a trip toward Jötunheim with Loki and two servants, Þjálfi and Röskva, the group is challenged to a set of contests at the hall of the giant king Útgarða-Loki. Loki loses an eating contest to Logi, unaware he’s competing against wildfire itself. Þjálfi loses a footrace to Hugi, who is literally the giant’s own thought. Thor, given a drinking horn to empty, barely lowers the level — because the horn is secretly connected to the ocean. He tries to lift a grey cat off the floor and can only raise one paw — because the cat is Jörmungandr, the World Serpent, disguised and coiled around the entire earth. Finally he wrestles an old woman named Elli to one knee before being forced down himself; she is old age, which eventually humbles everyone. Útgarða-Loki reveals the trickery only once the visitors are safely gone, admitting that Thor’s performance against forces of that scale was genuinely terrifying to watch.

Fishing for Jörmungandr: Thor vs. the World Serpent

Thor gets a second, more direct shot at the World Serpent on a fishing trip with the giant Hymir. Using an ox head as bait, Thor hooks Jörmungandr from the seabed and hauls it up until the two are eye to eye, the serpent spitting venom across the waves. He raises Mjölnir to finish it — but Hymir, terrified of what a dead World Serpent might mean for the structure of the cosmos, cuts the line, and Jörmungandr sinks back into the deep to wait for their real rematch.

Thursday and Ragnarök: How Thor Named a Weekday and Met His End

When Germanic peoples adapted the Roman week, they swapped their own gods in for the Roman ones: dies Iovis, “Jove’s day,” became Thor’s day because Thor and Jupiter were both thunder-wielding sky gods. That’s the entire etymology behind Thursday — no different from how Tuesday, Wednesday, and Friday preserve Tiw, Odin, and Frigg.

Thor doesn’t get a quiet retirement, though. At Ragnarök, prophecy says he finally kills Jörmungandr for good — then manages only nine steps before the serpent’s venom drops him dead on the field. It’s a fitting end for a god defined less by immortality than by doing the job in front of him.

Quick Answers

Is Marvel’s Thor accurate to the myths? Only loosely — the hammer and temper are there, but the mythological Thor is older, red-bearded, and far more of a working protector than a royal heir.

What is Thor’s hammer called and who made it? Mjölnir, forged by the dwarf brothers Brokkr and Sindri, with a handle shortened by Loki’s sabotage.

Why is Thursday named after Thor? Germanic peoples renamed the Roman “day of Jove” for their own thunder god, Thor, since both were seen as sky-thunder deities.

How does Thor die? At Ragnarök he kills the World Serpent, Jörmungandr, then dies from its venom nine steps later.
