Sigyn ("victory-friend") is defined by one unbearable image. When the gods bound Loki in the cave with the entrails of his own son and Skaði fixed a serpent above his face, Sigyn — whose son had just been killed to make her husband's fetters — chose to stay. She stands holding a bowl over Loki's face, catching the venom drop by drop; only when she turns to empty it does the poison strike, and his convulsions are earthquakes.
The Eddas never explain her; they don't need to. In two lines she becomes the mythology's study of loyalty past all reason — grieving mother, wronged wife, and voluntary prisoner of the world's worst man until Ragnarök frees them both. The image is old: the Gosforth Cross carved her with her bowl in the 900s.
The binding in the cave
The scene needs its full context to weigh what Sigyn does. After Loki engineered the death of Baldr and then, disguised as the giantess Þökk, refused the weeping that would have freed him from Hel, the gods' patience ended. Loki fled, hid on a mountain, built a house with four doors to watch every approach, and spent his days as a salmon in the waterfall of Fránangr. It was his own cleverness that caught him: he had invented the net, and Kvasir — in Snorri's telling, the wisest of beings — read its shape in the ashes of Loki's hearth. Netted and hauled ashore by Thor, he was carried to a cave.
Then Gylfaginning turns pitiless. The gods took Loki's two sons by Sigyn, Narfi and Váli. They turned Váli into a wolf, and the wolf tore his brother Narfi apart. With Narfi's entrails they bound Loki across three stones — under his shoulders, his loins, his knees — and the fetters turned to iron. Skaði fastened a venomous serpent above his upturned face. (The prose ending of Lokasenna tells it with the sons' roles differently distributed — there Narfi becomes the wolf — one of several signs the tradition wobbled on the details but not on the horror.)
And then, from inside the atrocity, the myth produces its one gentle motion: "Sigyn, his wife, stands beside him and holds a basin under the drops of venom." That is her decision, made in the same hour her sons were destroyed — one killed, one made the killer — to serve her husband's torment. When the basin fills she must turn away to pour it out; in those moments the venom falls on Loki's face, and he wrenches so hard that the whole earth shakes. "That is what you call an earthquake," Snorri finishes. Sigyn's vigil is thus built into the very seismology of the world: every tremor humans feel is the interval when her bowl is away.
Who is Sigyn?
The sources give her a name, a marriage, and the vigil — almost nothing else. Her name compounds sigr, "victory," with a second element usually read as "friend" or "woman": Victory-friend, a name of the same warlike stamp as the valkyries', which sits strangely and beautifully on the mythology's least martial figure. She is counted among the Ásynjur, the goddesses of the Æsir — Snorri lists her, and the tenth-century skald Þjóðólfr of Hvinir already calls Loki farmr Sigynjar arma, "the burden of Sigyn's arms," in the poem Haustlöng. That kenning is precious: it proves the marriage, and perhaps the embrace of the vigil itself, was proverbial in Norway a good three centuries before Snorri wrote. Völuspá gives her the other early witness: the seeress, describing the bound prisoner beneath the grove of hot springs, ends the stanza, "there sits Sigyn, though over her husband she is not very glad." The dry understatement — sitr þó Sigyn, um sínum ver vel glýjuð — is the closest the poems come to describing her feelings, and its restraint has broken more hearts than any lament.
Nothing is said of her parentage, her origin, or her fate at Ragnarök. When Loki breaks free at the world's end, the sources follow him to the last battle and never mention her again. The vigil simply ends where the world does.
The stone witness: the Gosforth Cross
Sigyn has one attestation older than any manuscript. The Gosforth Cross, a slender sandstone cross standing in a Cumbrian churchyard in northwest England, was carved in the first half of the tenth century by Norse settlers negotiating between the old myths and the new faith. Among its panels of Ragnarök imagery — Víðarr wrenching the wolf's jaws, Heimdallr with his horn — is a bound, twisting figure beneath a knotted serpent, and beside him a kneeling woman holding out a vessel. It is Loki and Sigyn, almost exactly as Snorri would describe them three hundred years later; carved on a Christian cross, the faithful wife under the serpent may even have been meant to echo other vigils at other executions. Whatever the carver intended, the stone proves that Sigyn's bowl was already the fixed emblem of the story in the 900s.
In the primary sources
Sigyn appears in the Prose Edda (Gylfaginning: the binding and the vigil; Skáldskaparmál: listed among the Ásynjur, with Loki "husband of Sigyn" in kennings and Haustlöng quoted), in the Poetic Edda (Völuspá's stanza on the bound Loki; the prose conclusion of Lokasenna; a mention in the "Loki's kin" catalogue of the þulur), and in stone on the Gosforth Cross. She has no other myths, no cult traces, and no recorded ancestry. Everything the tradition wanted to say with her, it said in one image.
Legacy
Sigyn's afterlife belongs to the Romantics and their heirs: painters and sculptors of the nineteenth century — Eckersberg, Winge, and others — returned again and again to the woman with the bowl, and Théophile Gautier's generation made her a byword for wifely devotion. Modern writers have complicated her: comics, novels, and contemporary Heathenry variously read her as devotion itself, as a study in trauma, or as a goddess of endurance, keeping vigils of her own. However she is read, a bowl held steadily under dripping ruin has become one of mythology's universally recognised images — and it is entirely Sigyn's.
Frequently asked questions
Who is Sigyn in Norse mythology?
Sigyn is a goddess of the Æsir and the wife of Loki. She is remembered for a single act: after the gods bound Loki in a cave beneath a venom-dripping serpent, she chose to remain beside him, catching the poison in a bowl — a vigil that lasts until Ragnarök.
What happened to Sigyn's sons?
The gods destroyed them to punish Loki. According to Gylfaginning, her son Váli was transformed into a wolf and tore his brother Narfi apart, and Narfi's entrails became the fetters that bind Loki. The Lokasenna prose swaps the brothers' roles, but in every version Sigyn loses both sons in the same hour.
Why do earthquakes happen, according to this myth?
When Sigyn's bowl fills with venom she must turn away to empty it, and in those moments the serpent's poison falls on Loki's face. He convulses so violently that the earth shakes — Snorri says this is the origin of earthquakes.
Does Sigyn stay with Loki until Ragnarök?
Yes. The sources say Loki lies bound, with Sigyn beside him, until the end of the world, when he breaks free to fight against the gods. What becomes of Sigyn at Ragnarök is never told; she disappears from the story the moment the vigil ends.
What is the Gosforth Cross's connection to Sigyn?
The tenth-century Gosforth Cross in Cumbria, England, carries a carving of a bound figure beneath a serpent with a kneeling woman holding a vessel beside him — Loki and Sigyn. It is the oldest surviving witness to the scene, predating the written Eddas by roughly three centuries.
