Mjölnir
Mjölnir, the hammer of the thunder god Thor, carries a distinction few mythological objects share: it served simultaneously as a weapon of mass destruction and a sacred instrument for blessing the living and the dead. A small copper amulet found in Öland, Sweden, dating from the 11th century, captures this duality with unusual clarity. Its inscription, translated by runologists Mindy MacLeod and Bernard Mees, pleads: "May Thor protect him with his hammer which came from out of the sea." That same hammer smashed the skulls of giants, sanctified wedding ceremonies, and revived slaughtered goats. How did a single object come to hold such contradictory power? What do around 1,000 excavated pendants scattered across the Nordic countries, England, northern Germany, the Baltic countries, and Russia tell us about the people who wore them? And why, more than a thousand years after the Viking Age, does the symbol appear on military grave markers issued by the United States National Cemetery Administration?
Linguists have argued over Mjölnir's name for generations, and the dispute has not been settled. The Old Norse form Mjǫllnir developed from the Proto-Norse form reconstructed as melluniaR, and three competing derivations have each attracted serious scholarly support.
One proposal traces the name to Old Church Slavonic mlunuji and Russian molnija, both meaning "lightning". Under this reading, either Norse borrowed from a Slavic source or both languages inherited the word from a shared common ancestor, making Mjölnir "the lightning-maker".
A second proposal finds the root in Old Norse mjǫll, meaning "new snow", and modern Icelandic mjalli, meaning "the color white", which would render the name as something like "shining lightning weapon".
The third proposal connects the hammer's name to Old Norse mala, meaning "to grind", alongside Gothic malwjan carrying the same meaning. Under this reading the weapon's name simply means "the grinder". The three proposals are not entirely at odds: lightning that grinds, shines, and strikes shares qualities with a hammer that smashes skulls and splits mountains. The name's ambiguity may reflect the object's own layered nature.
The eddic poem Þrymskviða gives the hammer its most theatrical moment. Thor wakes to find Mjölnir gone, and his reaction is visceral: he pulls his beard, shakes his head, and hunts the hall. The jötunn Þrymr, it turns out, has buried the hammer deep in the ground and will only return it if the gods deliver Freyja as his bride.
Freyja's response to the proposal is memorable. When Thor and Loki ask her to put on a bridal head-dress and travel to Jötunheim, she is so enraged that the hall shakes and her necklace Brísingamen breaks off.
The god Heimdallr then proposes an alternative: Thor should wear the bridal head-dress himself, with Brísingamen around his neck. Thor initially refuses, and Loki must argue that unless he goes, the jötnar who stole the hammer will soon call Asgard their home. Thor relents. Loki dresses as the bridal maid, and the two ride Thor's goat-drawn wagon to Jötunheim, splitting mountains along the way.
At the wedding feast, Þrymr watches "Freyja" consume one ox, eight salmon, and three casks of mead. Loki explains the bride had not eaten for eight nights because she was so eager to arrive. When Þrymr lifts the veil to kiss his bride, he springs back from eyes that burn like fire. Loki explains those sleepless nights again. Finally, Þrymr calls for Mjölnir to be laid on the maiden's knee to sanctify the marriage by the hand of the goddess Vár. The hammer is placed in "Freyja"'s lap. Thor laughs internally, seizes it, kills Þrymr and another jötunn, and pummels the assembled guests. The poem ends with a prose note confirming this is how the god recovered his weapon.
Skáldskaparmál in the Prose Edda offers an origin story that begins with a petty act of vandalism. Loki cuts the goddess Sif's hair, and when Thor discovers this, he grabs Loki and threatens to crush every bone in his body unless Loki makes it right. Loki travels to the svartálfar, and the Sons of Ivaldi produce three wondrous objects: Sif's gold hair, the ship Skíðblaðnir for the god Freyr, and Odin's spear Gungnir.
Then Loki makes a wager with the dwarf Brokkr, staking his own head on whether Brokkr's brother Eitri can produce three objects of equal quality. As Eitri works, a fly enters the workshop and bites him three times. On the first bite, Eitri stays steady and produces the golden boar Gullinbursti from a pig skin. On the second bite, Brokkr holds firm and draws the ring Draupnir from gold, a ring that produces eight more of itself every nine nights. On the third bite, the fly lands on Brokkr's eyelid and draws blood that obscures his vision. He flinches. Eitri inserts iron and draws out the hammer Mjölnir.
Brokkr presents the hammer to Thor and explains its properties: it can strike as hard as the wielder desires without failing; it will never miss when thrown; and it will always return to Thor's hand. It is small enough to be kept inside a shirt. The single flaw, Brokkr admits, is that the handle is rather short, a consequence of that third fly bite. The assembled gods, Odin, Thor, and Freyr, judge the hammer to be the best of all six objects. Loki keeps his head, though just barely.
Among the roles the hammer plays in the textual record, its ceremonial function is perhaps the least expected. In Gylfaginning, Thor raises the hammer at dawn to bless the skins of his two slaughtered goats, Tanngrisnir and Tanngnjóstr, and the animals stand up alive. One goat is lame because the peasant's son Þjálfi had split a ham-bone to reach the marrow during dinner, and the hammer's consecration could not undo that damage entirely.
At the ship funeral of the god Baldr, Thor consecrates the burning vessel with Mjölnir. The goddess Nanna, Baldr's wife, dies of grief at the sight of the body and is placed on the pyre beside him. A dwarf named Lit runs before Thor's feet, and Thor kicks him into the flames.
These ritual uses were apparently not confined to myth. The 12th century Danish author Saxo Grammaticus, in book 13 of his Gesta Danorum, records that in 1125 Magnus the Strong removed large bronze hammer models from a temple dedicated to Thor. The account explains that ancient people used these heavy hammers to simulate the crashing of thunder, believing the sound of the smith's toil could imitate the sky. Scholar H.R. Ellis Davidson, surveying the full range of the hammer's roles, concluded that its power appeared to cover birth, marriage, death, burial, cremation, weapons, feasting, traveling, land-taking, and the making of oaths.
Around 1,000 hammer pendants have been excavated from sites across what are now the Nordic countries, England, northern Germany, the Baltic countries, and Russia. Most are simple pieces in iron or silver. Around 100 have more advanced designs with ornamental work.
As of 2004, ten percent of all finds came from graves, and nearly all of those graves were cremations. The burials are often identified as women's graves. One find from Hilde in Stryn Municipality, Norway, consists of a ring bearing nine hammers, recovered from a female cremation burial inside a boat mound and dated to the 10th century. A find from Kaupang in Larvik Municipality, Norway, is an undecorated iron piece dated to around 800-960. The most remarkable find for its content is a 10th century pendant from Købelev in Lolland Municipality, Denmark, the only hammer found with a runic inscription: its text reads "Hmar x is", meaning "This is a hammer".
In Viking Age cremation graves in the Mälaren area, Åland, and Russia, archaeologists have identified iron rings with multiple amulets attached, many shaped like hammers. Found in cinerary urns in graves of both sexes, these rings, called Thor's hammer-rings, may have played a role in cremation practices, though their exact function remains unknown. The earliest examples date to the Vendel Period, but they became more common in the late Viking Age.
In 1999, German archaeologist Jörn Staecker proposed a formal typology for the finds based on decorative style and material. In 2019, American scholar Katherine Suzanne Beard extended that typology to account for hammer shape and suspension type, and also launched the Eitri: The Norse Artifacts Database, an online database cataloguing the finds and their discovery contexts. As Beard notes, Thor is the only known god from the Viking Age called upon to bless or hallow runestones, a distinction scholars have observed since at least the 19th century.
Henry Fuseli painted Thor Battering the Midgard Serpent in 1780, and the visual tradition has continued in various forms ever since. The hammer now appears in an unusually broad range of modern contexts, from municipal coats of arms to stadium attractions to military cemeteries.
Tórshavn Municipality, the capital of the Faroe Islands, features a depiction of Mjölnir on its seal and coat of arms, as does Torsås Municipality in Sweden. The Mjølnir crater, a meteorite crater off the coast of Norway, carries the name. The Thor's Hammer rollercoaster operates at the Tusenfryd theme park in Norway. The American-Norwegian metal band Thorr's Hammer and the Icelandic rock band Thor's Hammer both take their names from the weapon. The Norwegian football club FK Mjølner does as well.
In the United States, the National Cemetery Administration offers Thor's Hammer as religious emblem number 55, titled "Hammer of Thor", available for military veteran grave stones.
The symbol is central to Heathenry, a modern religious movement. Writing in 2006, scholars Jenny Blain and Robert J. Wallis called the Thor's hammer pendant "the most common of heathen sacred artefacts" and described how adherents express their spirituality through the display of reproduced objects including hammer pendants, through pilgrimages to sacred sites, and through visits to museum displays of ancient artefacts.
The symbol has also been appropriated by white nationalist and neo-Nazi groups, a development noted explicitly in the Anti-Defamation League symbol database. Scholar Katherine Beard responds directly: most people who wear hammer pendants today do so for cultural, religious, or decorative reasons and maintain no ties to any racist groups or beliefs. The increase in hammer amulet popularity during the Viking Age may itself have been a response to the spread of Christian cross pendants during Christianization, suggesting the symbol has always carried contested meanings alongside its power.

Common questions
What is Mjölnir in Norse mythology?
Mjölnir is the hammer of Thor, the Norse god of thunder. It functioned both as a devastating weapon used to slay giants and as a sacred instrument for blessings, consecrations, and healing. The hammer is attested in sources including the 11th century Kvinneby amulet, the Poetic Edda, and the Prose Edda.
What does the name Mjölnir mean?
The etymology of Mjölnir is disputed. Proposed derivations connect it to words meaning "lightning" in Old Church Slavonic and Russian, to Old Norse words meaning "new snow" or "white" yielding the sense "shining lightning weapon", or to Old Norse and Gothic roots meaning "to grind" yielding "the grinder".
Who forged Mjölnir and why does it have a short handle?
The hammer was forged by the dwarf Eitri while his brother Brokkr worked the bellows. A fly bit Brokkr on the eyelid during the final stage, causing blood to obscure his vision and making him flinch. As a result, Mjölnir was pulled from the forge with a shorter handle than intended. The assembled gods Odin, Thor, and Freyr still judged it the best of all objects presented to them.
How many Mjölnir pendants have been found archaeologically?
Around 1,000 hammer pendants have been unearthed across what are now the Nordic countries, England, northern Germany, the Baltic countries, and Russia. Most are simple pieces in iron or silver; around 100 have more ornate designs. As of 2004, ten percent of all finds came from graves, nearly all of which were cremations.
What happened to Mjölnir after the events of Ragnarök according to Norse sources?
According to both the eddic poem Vafþrúðnismál and Gylfaginning in the Prose Edda, Thor's sons Móði and Magni survive Ragnarök and return to Asgard holding their father's hammer Mjölnir. The 9th century skald Bragi Boddason and 10th century skald Þjóðólfr of Hvinir also reference the hammer in surviving skaldic verse.
Is the Thor's Hammer symbol used in modern religion?
Yes. Mjölnir is the most common sacred artefact among adherents of Heathenry, a modern religious movement, according to scholars Jenny Blain and Robert J. Wallis writing in 2006. In the United States, the National Cemetery Administration offers it as religious emblem number 55, titled "Hammer of Thor", for use on military veteran grave stones.
