The Vanir are the second family of gods in Norse mythology besides the Æsir – and the sources explicitly name only three of them: the sea god Njord and his children Freyr and Freyja. They stand for harvest, wealth, peace and a magic that even Odin wanted to learn. With the Æsir they fought the first war in the world, exchanged hostages and made peace. Whether they ever formed a separate group at all is a question scholars still argue about.
Open any dictionary of Norse gods at “Vanir” and you will find a family of three, a handful of poetic stanzas, a few notes by a thirteenth-century Icelandic scholar – and, filed next to them, an academic article called “An Obituary”. That is honestly where things stand. The Vanir are among the best-known and least tangible figures in the whole mythology. So let us follow the trail properly: what the sources actually say, what Snorri Sturluson added, and what modern scholars built on top of it.
The list is short. The sources clearly call only three gods Vanir: Njord (Old Norse Njörðr), lord of the coast, the sailing wind and the catch, and his two children Freyr and Freyja. In Gylfaginning (ch. 23) Snorri describes Njord as so rich that he can grant land and goods to anyone who calls on him. Freyr rules rain, sunshine and the fruit of the earth; Freyja rules love, desire and sorcery. Her byname Vanadís, “the dís of the Vanir”, ties her to the family by name.
Two marginal figures join them. In Ynglinga saga (ch. 4) Snorri mentions Njord’s unnamed sister, who was his wife among the Vanir and the mother of Freyr and Freyja. In the same saga, wise Kvasir is the cleverest man of the Vanir. Whether the mysterious Gullveig was one of them, no source says; that many scholars identify her with Freyja is an interpretation, not a finding.
Everything beyond that is guesswork. Heimdall has often been declared a Van because a line in Þrymskviða (st. 15) calls him foreseeing “like other Vanir” – but the line can equally be read as a comparison. Listing Ullr, Nerthus or Skadi among the Vanir has no textual support. Skadi is a giantess who marries Njord; that does not make her one of his kin.
More than a thousand years before the Edda, the Roman historian Tacitus describes in his Germania (ch. 40, around AD 98) a cult shared by seven northern tribes, among them the Angles and the Warni. They worshipped Nerthus, “that is, Mother Earth”. On an island in the Ocean, he writes, stood her sacred grove and a covered wagon; when the goddess travelled about in it, all weapons were laid aside and there was peace and rejoicing. Afterwards the wagon was washed in a hidden lake, and the slaves who served at the rite were swallowed by the water.
The twist is linguistic. Nerthus and Njörðr go back to the same Proto-Germanic form, *Nerþuz. A goddess in the first century, a god in the thirteenth – how does that fit? Three explanations are on the table. One: Tacitus adjusted the gender to a Roman idea of “Mother Earth”. Two: there was a divine pair sharing one name, like Freyr and Freyja later – Njord’s nameless sister-wife would then echo the female half. Three: same name, unrelated figures.
The wagon remains striking. Nerthus’s procession of peace recalls a story in the Flateyjarbók in which Freyr’s image is driven from farm to farm through Sweden. A line across a millennium? Plausible, but not provable.
The most famous Vanir myth is a war – according to Völuspá, “the Prophecy of the Seeress”, the first war in the world. In the usual modern numbering (stanzas 21–24) the seeress tells of a woman called Gullveig, “gold-might” or “gold-drunkenness”, whom the gods pierce with spears and burn in the High One’s hall. Three times she is burned, three times reborn. Directly afterwards she is called Heiðr and practises seiðr, the art of sorcery. The gods hold council over whether to pay compensation or whether all of them should share in the offerings. Then Odin hurls his spear over the host, and the first killing in the world is done. The rampart of the Æsir is broken, and the Vanir, skilled in battle, trample the field.
That is all the poem says. Who Gullveig is, why she is burned and how the war ends, it leaves open. Most scholars assume the Gullveig stanzas belong to the war because they stand right before it. A popular reading has the Vanir send Gullveig – greed for gold personified – to the Æsir, with her mistreatment sparking the war. That is a modern reconstruction. We tell the whole sequence in our article on the Æsir-Vanir war.
Notice the defensive image: the Æsir have a fortress wall, and it breaks. The Vanir here are not gentle harvest gods but warriors who know their business.
The story only gets detailed with Snorri Sturluson, the Icelandic scholar and politician writing around 1220–1230. In Ynglinga saga (ch. 4), the opening part of his history of kings Heimskringla, he tells the gods as if they were humans: Odin is a war-king from Asia who fights the Vanir. Each side ravages the other’s land until both are weary of it. They arrange a peace meeting and exchange hostages.
The Vanir give their best: Njord the wealthy and his son Freyr. The Æsir give Hœnir, tall and handsome and seemingly born to lead, and clever Mímir. In return the Vanir also send their wisest, Kvasir. Among the Vanir, Hœnir is made a chieftain at once – but he only shines while Mímir stands at his side and whispers to him. When Mímir is away and a hard question comes up, Hœnir always gives the same answer: “Let others decide.” Feeling cheated, the Vanir cut off Mímir’s head and send it to the Æsir. Odin embalms it with herbs, sings spells over it, and from then on consults it for hidden knowledge.
This story exists only in Snorri. The Eddic poems know the hostage exchange, but more briefly. In Vafþrúðnismál Odin asks how Njord came among the gods, though he was not born of them. The answer:
“In the home of the Wanes did the wise ones create him,
And gave him as pledge to the gods;
At the fall of the world shall he fare once more
Home to the Wanes so wise.”
— Vafþrúðnismál 39, translated by Henry Adams Bellows (1923, public domain)
Loki, too, alludes in Lokasenna (st. 34) to Njord having been sent east to the gods as a hostage. Gylfaginning (ch. 23) states briefly that the Vanir gave Njord as a hostage and took Hœnir in exchange. Mímir is missing there; in the Edda he appears rather at the well where Odin pledged his eye. How the two Mímir traditions relate is an open question.
Snorri also gives a second, entirely different account of how the war ended. At the start of Skáldskaparmál, his handbook of poetic language, Bragi explains: when the gods made peace with the Vanir, both sides went to a vat and spat into it. As a token of the truce they did not want it lost, so they shaped a man from it: Kvasir. He was so wise that nobody could ask him a question he could not answer.
Kvasir travelled the world until the dwarfs Fjalarr and Galarr killed him. From his blood, mixed with honey, they brewed the mead of poetry. They told the gods that Kvasir had choked on his own knowledge because nobody was clever enough to question him. By a winding route the mead ended up with Odin – so, in this myth, poetry itself springs from the peace between two warring families of gods.
The two Kvasir versions openly contradict each other: once he is a Van and a hostage, once a being made from the spittle of peace. Snorri left both in place. There was no single, tidy Vanir story even in the thirteenth century – only fragments that one learned man tried to arrange.
Where do the Vanir live? In Vanaheimr, “the home of the Vanir”. The Poetic Edda names it only in stanza 39 of Vafþrúðnismál, quoted above; Snorri repeats in Gylfaginning that Njord was raised in Vanaheim. There is no description – no hall, no river, no place on the World Tree. The claim that Vanaheim is one of the “nine worlds” on Yggdrasil is a modern assignment; the sources mention nine worlds but never list them.
A second place name is worth knowing. In Ynglinga saga (ch. 1) Snorri locates a Vanaland or Vanaheimr on the river Tanais – today’s Don – which, he says, divides Asia from Europe. That belongs to his learned scheme of gods who were really immigrants from Asia: medieval geography, not a pagan world-picture.
And the future? According to Vafþrúðnismál, Njord returns to the Vanir “at the fall of the world”. Some scholars have concluded from this that the Vanir are untouched by the end of the world. Freyr, however, falls at Ragnarök against the fire giant Surtr. The Polish historian of religion Leszek Słupecki pointed out in 2011 that Ragnarök carries remarkably little weight in Vanir traditions – an observation, not settled doctrine.
What set the Vanir apart from the Æsir, Snorri states in a single loaded sentence. In Ynglinga saga (ch. 4) he says, in substance: while Njord lived among the Vanir he had his sister as his wife, for that was the law among them; their children were Freyr and Freyja. But among the Æsir it was forbidden to marry such close kin.
The Edda puts the same charge in Loki’s mouth. In Lokasenna he claims the gods caught Freyja with her brother, and taunts Njord with having fathered a son on his sister. These are insults in a flyting poem – but they match Snorri’s note. Whether a real cult practice stood behind it, perhaps a sacred marriage between priestess and god, is debated. The Norwegian historian of religion Gro Steinsland has read the motif of a sacred marriage between god and giantess as the basis of Norse royal ideology. That is not proven, but it is a serious scholarly thesis.
The second strange thing is seiðr. Freyja, says Snorri, was a priestess of sacrifice and was the first to teach the Æsir seiðr, which was customary among the Vanir. In later tradition this magic of prophecy and manipulation carried the stigma of “unmanliness” (ergi); Odin learned it anyway. In the Völuspá war, too, Gullveig-Heiðr is a seiðr-woman. If you want to understand the Vanir, there is no way round this knot of fertility, desire and sorcery.
Both male Vanir marry giantesses, and both marriages come at a price. In the Eddic poem Skírnismál Freyr falls in love with the giant’s daughter Gerðr after sitting, without permission, on Odin’s high seat Hliðskjálf. His servant Skírnir woos her on his behalf – and takes Freyr’s sword, which fights by itself, as his fee. Only threats and a rune-curse win Gerðr’s consent. According to Gylfaginning, Freyr later kills the giant Beli with a stag’s antler, and at Ragnarök he misses his sword.
Njord fares no better. The giantess Skadi may choose a husband among the gods as compensation for her slain father, but sees only their feet – and ends up with the sea god instead of Baldr. The marriage founders on the question of where to live: he cannot bear the wolves howling in her mountains, she cannot bear the gulls screaming on his shore. So tell Gylfaginning and Skáldskaparmál.
If the Vanir were merely a poets’ invention, cult evidence ought to be silent. It is not – at least not for Freyr and Njord.
Around 1075 Adam of Bremen describes the temple at Uppsala in his history of the archbishops of Hamburg (Gesta IV, 26–27). Three images stood there, he says: Thor in the middle, flanked by Wodan and Fricco, who grants mortals peace and pleasure; his image shows him “with an enormous phallus” (cum ingenti priapo). Offerings were made to him at weddings. Fricco is generally taken to be Freyr. Adam never went to Uppsala himself; he wrote from reports and with a missionary’s eye, and the exact appearance of the temple is disputed. That a fertility god ranked beside Thor and Odin at the very top is nevertheless taken seriously by most scholars.
Snorri makes Freyr the ancestor of the Swedish kings: under the name Yngvi-Freyr he ruled at Uppsala and built the great temple, and the Ynglings are named after him. After his death, the saga says, his men laid him in a mound and for three years poured gold, silver and copper into it through openings, and the good seasons continued (Ynglinga saga, ch. 10). Learned storytelling from the thirteenth century – but it binds royal grave, god and good year together.
The Flateyjarbók contains the tale of Gunnarr helmingr, who in Sweden accompanies the priestess travelling with Freyr’s image on a wagon, regarded as the god’s “wife”. The text is Christian and mocking, but it shows how people imagined the Freyr cult. Icelandic sagas know Freyr worshippers too: Hrafnkell in Hrafnkels saga is called “Freysgoði”, priest of Freyr, and shares his horse Freyfaxi with the god. In Gísla saga no snow settles on the burial mound of the Freyr worshipper Þorgrímr, because Freyr would not allow frost between them.
The oath is a gem. The Hauksbók version of Landnámabók preserves a formula sworn on the temple ring: “So help me Freyr and Njord and the almighty god (áss).” Who the “almighty áss” is remains open – the only gods named are the two Vanir.
The hardest evidence, though, comes from place names. Sweden and Norway hold numerous names with Frö- or Fröy-, such as Frösön in Jämtland, “Freyr’s island”, or names ending in -vi and -lunda that point to a sanctuary or sacred grove. Njord hides in Swedish names such as Närtuna (Uppland), Nalavi (Närke) or Mjärdevi near Linköping, whose older forms begin with Njärd- or Nerdh-; in Norway in Nærøya, in Iceland in Njarðvík. The Swedish onomastician Per Vikstrand has studied such divine names in the place names of central Sweden systematically. Individual etymologies can wobble; taken together, the names show that Freyr and Njord were more than figures of poetry. For an overview see our article on gods in place names.
The fertility thesis. For a long time the Vanir were simply “fertility gods” and the Æsir gods of war, law and rule. From this grew a historical reading: the war reflected a clash of two peoples or religions – settled farmers with a fertility cult against incoming warriors with sky gods, who eventually made common cause. No archaeological evidence matching such an invasion exists. The thesis is now regarded as outdated, even if it lives on in popular books.
Dumézil’s three functions. The French comparativist Georges Dumézil saw the Vanir as the “third function” of his Indo-European model: fertility, wealth, well-being – beside the first (sovereignty and magic: Odin and Týr) and the second (force: Thor). He compared the war with the conflict between Romans and Sabines, which ends with the Sabines being absorbed into the Roman community, and with Indian tales in which the Aśvin twins are admitted to the soma sacrifice only after a conflict. Elegant and stimulating. Critics find it too neat: Freyr is also a royal god and a warrior, Freyja takes half of the slain, and Odin is the greatest sorcerer of all. The functions bleed into one another.
The obituary. In 2010 the Austrian Old Norse scholar Rudolf Simek, then teaching at Bonn, published “The Vanir: An Obituary” in the RMN Newsletter of the University of Helsinki. His thesis: in poetry, vanir was originally just an archaic word for “gods”, like æsir. Only Snorri turned it into a separate group of gods, in order to explain the war in Völuspá. The word really is rare in poetry and appears in rigid formulas.
Replies came quickly and did not all point the same way. Clive Tolley pushed back with “In Defence of the Vanir” (2011), citing among other things Alvíssmál, where the Vanir appear with words of their own for the things of the world. Frog and Jonathan Roper tested the verses statistically (“Verses versus the ‘Vanir’”, 2011) and found the figures quite compatible with Simek’s hypothesis, while declining to call the problem solved. Leszek Słupecki disagreed with Simek. Terry Gunnell, in the Harvard volume Old Norse Mythology – Comparative Perspectives, argued that oral memory preserved a distinct Vanir cult with priestesses, wagon processions, sibling marriage and mound offerings. Jens Peter Schjødt held that “Vanir” remains the most practical label in any case. And in 2021, in a Festschrift for Simek, Frog went a step further with “The Æsir: An Obituary”: áss, too, might simply be a poetic synonym for “god”.
Where does the debate stand now? There is no consensus. What is certain: the boundary between “Æsir” and “Vanir” is far blurrier in the sources than handbooks often suggest. Equally certain: Freyr, Njord and Freyja have a distinct profile in cult and myth. Whether to call them “Vanir” is a question about terms, not about the gods.
In our workshop in Alsdorf people often ask us about Freyja, hardly ever about the Vanir as a group. Yet it is they who tell one of the wisest stories in the mythology: two powers that cannot defeat each other hand over their most precious as pledges and make something new out of peace – poetry. That a head rolls and a god loses his sword along the way does not make the myth smaller, only more honest. For both families side by side, see Æsir and Vanir and our Norse pantheon.
Who are the Vanir gods? Explicitly only Njord and his children Freyr and Freyja. Snorri adds Njord’s unnamed sister-wife and, in Ynglinga saga, Kvasir.
What is the difference between the Æsir and the Vanir? The Vanir are seen as gods of fertility, wealth, peace and seiðr magic, the Æsir as gods of rule, war and law. The sources draw that line less sharply than is often claimed.
Why did the Æsir and Vanir go to war? Völuspá gives no clear reason; the war follows the burning of Gullveig. Snorri tells the war without a cause and stresses the peace and the hostage exchange.
Where is Vanaheim? The sources do not describe it. In Ynglinga saga Snorri places a Vanaland on the river Don – thirteenth-century learned geography.
Is Nerthus one of the Vanir? Her name corresponds linguistically to Njord, and her wagon cult recalls Freyr. That she is a forerunner of the Vanir remains an interpretation.
Did the Vanir really exist as a separate group of gods? That is disputed. Rudolf Simek considers the group Snorri’s construction; many other scholars disagree. Undisputed is that Freyr, Njord and Freyja had their own cult profile.
For courage. For remembrance. For legends that live on.
