Loki: The Trickster the Gods Needed and Could Not Keep

Loki is the trickster of Norse mythology: a giant's son counted among the Æsir, blood brother to Odin, and the figure behind most of the gods' worst problems and best treasures. The Poetic Edda and Snorri Sturluson's Prose Edda follow him from clever companion to bound enemy who sails against the gods at Ragnarök.

Who Is Loki? A Giant's Son Among the Gods

Snorri introduces him in Gylfaginning chapter 33 with a warning label: Loki is the slanderer of the gods, fair to look at, evil in temper, and more changeable than anyone. His father is the giant Fárbauti. His mother is Laufey, also called Nál, and he carries her name, Loki Laufeyjarson. That alone is strange. Norse men were named for their fathers, and nobody knows for certain why Loki takes his mother's name. His brothers, Býleistr and Helblindi, survive almost only as names in the poems.

He is not Thor's brother. That family tree belongs to Marvel. In the sources, Loki's bond is with Odin, and it is older and odder: in Lokasenna stanza 9, Loki reminds Odin that the two mixed their blood in ancient days, and that Odin swore never to drink ale unless it was brought to both of them. That oath is a big part of why the gods cannot simply throw him out.

He is also the mythology's best shapeshifter. Across the sources Loki becomes a mare, a salmon, a fly, a falcon in borrowed feathers, and an old giantess, changing shape and sex without ceremony whenever the job requires it.

The Trickster Who Fixed What He Broke

Most Loki stories run on the same engine: he causes the crisis, the gods force him to solve it, and the solution usually leaves them richer than before.

Cutting off Sif's hair is the cleanest example. In Skáldskaparmál, Loki shears Thor's wife bald as a prank, and Thor threatens to break every bone in his body. To repay it, Loki commissions the dwarfs, then bets his own head that a second pair of smiths cannot outdo the first. The wager produces six treasures, including Odin's spear Gungnir, Freyr's ship and golden boar, and Thor's hammer Mjölnir. Loki keeps his head on a technicality, since the dwarf won the head but not the neck, and gets his lips sewn shut instead.

In Þrymskviða, when a giant steals Mjölnir and demands Freyja as ransom, Loki scouts Jötunheimr in Freyja's feather cloak and then talks Thor into a bridal veil. In Skáldskaparmál he hands the goddess Iðunn and her apples to the giant Þjazi to save his own skin, then steals her back as a falcon once the gods begin to age. And in Gylfaginning chapter 42 he sabotages a giant builder's wall by becoming a mare and luring away the work-stallion Svaðilfari, a trick that leaves him pregnant.

The pattern matters. For most of the mythic timeline, Loki is not the gods' enemy. He is their fixer, and they keep him around because he works.

What Do the Eddas Actually Say About Loki?

Nearly everything we know comes from two Icelandic sources written down in the 13th century, and they do not always agree in tone.

The Poetic Edda gives us Loki in his own voice. In Lokasenna, "Loki's quarrel," he crashes a feast in Ægir's hall, kills a servant, and insults every god at the table until Thor shows up with the hammer. The prose ending of the poem then describes his capture and binding. Völuspá stanza 35 shows him already bound, with Sigyn at his side, and a later stanza puts him at the helm of a ship full of Hel's people, sailing to the last battle.

Snorri's Prose Edda, written around 1220, stitches the scattered poems into one story: Gylfaginning chapters 33 and 34 introduce Loki and his children, chapter 42 tells the builder episode, chapters 49 and 50 cover Baldr's death and the binding, and chapter 51 gives Loki his role at Ragnarök. Skáldskaparmál adds the treasures and the Iðunn theft.

One honest caveat: Snorri was a Christian writing two centuries after Iceland's conversion, and scholars have long argued over how far he sharpened Loki into a devil figure. The older poems never pause to explain Loki; they assume the audience already knows him. Where the two traditions disagree, this article says so.

Sigyn, Angrboda, and the Children

Loki's wife is the goddess Sigyn, and their sons are Váli and Narfi, the second also called Nari. With the giantess Angrboða he fathered three of the mythology's great monsters: the wolf Fenrir, the world serpent Jörmungandr, and Hel, who rules the dead (Gylfaginning chapter 34). As the mare in the builder story, he also gave birth to Sleipnir, Odin's eight-legged horse. Each of those figures deserves more than a paragraph, so we tell their stories separately in our post on Loki's children and the fates the gods dealt them.

Baldr's Death and the Binding

Here the sources genuinely split, and it is worth being precise about who says what.

In Snorri's telling (Gylfaginning chapter 49), Frigg takes oaths from everything in the world not to harm her son Baldr, skipping only the mistletoe, which she judged too young to swear. Loki learns this by trickery, puts a mistletoe dart in the hand of Baldr's blind brother Höðr, and guides the throw. Baldr falls dead. When the gods try to weep him back out of Hel, a lone giantess named Þökk refuses, and Snorri adds that people believe Þökk was Loki in disguise.

The poems are thinner. Völuspá names Höðr as the slayer and says nothing clear about Loki guiding the shot. Baldrs draumar names Höðr as the slayer and never ties Loki to the deed; Loki appears only in its last stanza, already in bonds. But the Poetic Edda does convict him once, in his own words: in Lokasenna stanza 28 he taunts Frigg that he is the reason she will never see Baldr ride home again. The tradition blamed Loki; Snorri filled in the mechanics, and we cannot know how much of the mistletoe scene is his construction.

The punishment is the most brutal scene in the mythology. In Gylfaginning chapter 50, the gods hunt Loki down while he hides as a salmon, catch him in a net, turn his son Váli into a wolf that tears his brother Narfi apart, and bind Loki with the dead son's entrails, which harden into iron. The Lokasenna prose ending keeps the same scene but swaps the sons: there Loki is bound with Váli's guts while Narfi becomes the wolf. Skaði fastens a venomous serpent above his face. Sigyn stands beside him holding a bowl to catch the poison, and whenever she leaves to empty it, the drops strike his skin and he convulses hard enough to shake the ground. That, the sources say, is what earthquakes are.

Loki at Ragnarök

He does not stay bound. In Gylfaginning chapter 51 Loki breaks free when Ragnarök begins and arrives as an open enemy, leading all of Hel's champions to the plain of Vígríðr. Who steers Naglfar, the ship built from dead men's nails, depends on the source: Snorri gives the helm to the giant Hrymr, while Völuspá stanza 51 puts Loki at the helm of the ship that carries Hel's people to the last battle.

On the field he meets Heimdallr, the watchman of the gods, and they kill each other. Fire takes the world soon after. It is a fitting pairing: the god of vigilance and the god of disruption, cancelling each other out at the end of all things.

Was Loki Ever Actually Worshipped?

As far as the surviving evidence shows, no. Thor, Odin, and Freyr left their names on farms, islands, and cult sites across Scandinavia. Loki left no place names scholars can point to with confidence, and no source describes a sacrifice or a prayer offered to him. He seems to have been a god people told stories about, not one they asked for help.

One object may show his face. A soapstone hearth stone found at Snaptun in Denmark, dated to around the year 1000, carries a mustached face with what look like stitched scars across the lips, and many scholars read it as Loki because of the lip-sewing episode in Skáldskaparmál. It is an interpretation, not a certainty.

What Loki originally was remains an open argument. A fire spirit, a demonized double of Odin, a pure story engine: each theory has had serious defenders for over a century, and none has won.

Why People Still Wear the Serpent

Loki's story is told in serpents. There is the venom-dripping snake fixed above his bound face, and there is the world serpent he fathered, coiled around Midgard. When people wear serpent imagery today, they usually mean what the myth means: cunning, transformation, and the admission that a little chaos belongs in every order. It reads differently from a hammer. A Mjölnir says protection. A serpent says wit.

FAQ: Loki in Norse Mythology

Is Loki a god or a giant?

Both, in a sense. By birth he is the son of the giant Fárbauti and of Laufey, yet Snorri counts him among the Æsir in Gylfaginning chapter 33, and he lives with the gods in Asgard. His giant blood never stops mattering: when Ragnarök comes, he fights on the giants' side.

Is Loki Thor's brother?

No. That relationship is a Marvel invention. In the Eddas, Loki's sworn bond is with Odin: Lokasenna stanza 9 has Loki remind Odin that the two mixed blood as sworn brothers in the old days. Loki travels with Thor often in the myths, but the two are not kin.

Who are Loki's children?

With his wife Sigyn he has the sons Váli and Narfi, also called Nari. With the giantess Angrboða he fathers Fenrir the wolf, the world serpent Jörmungandr, and Hel, ruler of the dead, according to Gylfaginning chapter 34. In mare's shape he also gave birth to Sleipnir, Odin's eight-legged horse.

How does Loki die?

At Ragnarök. Gylfaginning chapter 51 says Loki and the watchman god Heimdallr meet on the battlefield and kill each other, in the same battle where the wolf Fenrir swallows Odin and Thor falls to the world serpent's venom. Before that final day, the sources treat Loki as bound but alive.

Was Loki evil?

Not for most of the mythology. Through the bulk of the stories he is the gods' problem-solver, winning them Mjölnir, Sleipnir, and Odin's spear. The turn comes with Baldr's death, after which the sources treat him as an enemy. Scholars still debate how much of that darkness is original and how much is Snorri's Christian-era framing.
