Vígríðr

The end of the world has a venue, booked in advance. Vígríðr ('the field where battle surges') stretches a hundred leagues in every direction — Vafþrúðnir cites its dimensions as settled fact, the way one might give the acreage of a famous farm. There Surtr's fire-host, the frost-giants, Loki with the dead of Hel, Fenrir, and the World Serpent will form against the gods and the einherjar marching out of Valhalla's doors.

Every named duel of Ragnarök — Odin and the wolf, Thor and the serpent, Freyr and Surtr, Heimdallr and Loki — happens on this grass. That the battlefield is known, measured, and unavoidable centuries in advance is the purest expression of Norse fatalism: the gods could, in principle, simply not attend. They will attend.

A battlefield with a survey on file

The detail comes from Vafþrúðnismál, and the setting makes it perfect. Odin, travelling in disguise, has staked his head on a wisdom contest with the ancient giant Vafþrúðnir, and among his questions is this: what is the name of the plain where Surtr and the sweet gods will meet in battle? The giant answers without hesitation: 'Vígríðr is the plain where Surtr and the sweet gods shall meet in battle; a hundred leagues it is on every side — that field is appointed to them.'

Notice what kind of fact this is. Not a prophecy hedged in riddles, but a land survey: name, dimensions, booking. The giant recites it the way one might give the acreage of a famous estate, and Odin — who already knows the answer, as he knows all the answers he asks — is not gathering intelligence but confirming the file. The end of the world, in Norse cosmology, has the administrative solidity of a law court's calendar. A rastir (league) was the distance between rests on a journey, several miles; a hundred of them each way makes a parade-ground fit for every army in existence, because every army in existence is exactly what will be on it. Snorri, in Gylfaginning, repeats the figure and files the field's location for the hosts riding in — the sons of Múspell cross the shattering Bifröst and ride to Vígríðr, where all the rest converge. (One Eddic poem, Fáfnismál, preserves a variant tradition naming the meeting-place Óskópnir, an island; the mainstream of the sources holds to Vígríðr.)

The muster: who comes to Vígríðr

Snorri choreographs the arrivals like a herald with a list. From the sea comes Jörmungandr, the World Serpent, who has churned the ocean over the land as he comes ashore, blowing venom over sky and sea. Beside him advances Fenrir, freed at last from the fetter, his upper jaw against the sky and his lower against the earth — 'he would gape wider if there were room.' The ship Naglfar, made of dead men's nails, sails loose on the flood, ferrying giants, with Loki — broken out of his own bonds — at the helm of the host of Hel's dead. From the south rides Surtr with the sons of Múspell, fire before him and after him, his sword outshining the sun; their riding breaks Bifröst beneath them. The frost-giants come with Hrym. All of them ride to the field called Vígríðr.

Against them: the gods, warned by Heimdallr's horn-blast heard through all worlds. Odin rides first in his gold helmet and mail, spear in hand, at the head of the einherjar — the entire harvest of Valhalla, out through the 540 doors, eight hundred abreast. Before riding, Odin pauses at Mímir's well to consult the head of Mímir one last time — a general checking the intelligence one final time on the way to a battle whose outcome the intelligence has always been unanimous about.

The duels fought on this grass

Ragnarök on Vígríðr resolves into single combats, each an old account settled. Odin goes against Fenrir — the wolf he ordered bound, whose binding cost Týr a hand — and the wolf swallows him; his son Víðarr avenges him at once, stepping on the wolf's lower jaw and tearing him apart. Thor meets Jörmungandr, the serpent he once hooked from a boat and has hated ever since; he kills it, walks nine paces, and falls dead of its venom. Freyr faces Surtr and falls, missing the good sword he traded away for love of Gerðr — the price of that bargain collected here, on this field. Týr fights the hound Garmr; each kills the other. Heimdallr and Loki, the watchman and the infiltrator, end each other last. Then Surtr flings fire over the world, and the field, the armies, and the earth itself go into the flame together.

That the venue for all this was named and measured ages in advance is the sharpest single expression of the Norse view of fate. The gods have the date approximately, the location exactly, and the casualty list by name — the seeress of Völuspá read it to Odin personally. They could, in principle, simply not attend; no source ever entertains the idea. The field is 'appointed to them,' says Vafþrúðnir — the same word-world as ørlög, the laid-down law. What remains open on Vígríðr is not the outcome but the conduct, and the myths spend their attention accordingly: on Odin riding first, on Thor's nine paces, on Víðarr's silent, prepared boot. A hundred leagues square of foreknown grass, and every step on it freely, magnificently taken.

In the primary sources

Vafþrúðnismál stanza 18 (Poetic Edda) is the anchor: the field's name, its hundred-league extent, and its status as the appointed meeting-place of Surtr and the gods. Snorri's Gylfaginning (Prose Edda) cites the stanza and builds the full battle-narrative around it — the convergence of Fenrir, Jörmungandr, Loki, Hrym, and Surtr's riders on Vígríðr, and each duel in sequence. Völuspá supplies the events of the last battle in prophetic order, though without naming the field; Fáfnismál preserves the variant meeting-place Óskópnir. After the fire, Völuspá and Snorri agree on what no one on Vígríðr will see: the earth rising green from the sea a second time, the surviving young gods gathering, and the golden game-pieces found again in the grass — a sequel the battlefield's dead purchased but do not attend, except for those, like Víðarr, fated to walk off the field into the new world.
