Sigurd and the Dragon Fafnir

A young man with no father, a sword broken in two, and a dragon coiled on a hoard of cursed gold. This is the story of Sigurd and Fafnir — the greatest dragon-slaying in the northern world, and a warning, spoken by the dying dragon itself, that gold can be the deadliest poison of all.

Every culture that tells stories eventually tells a dragon story, but few are as old, as strange, or as influential as this one. Sigurd’s killing of the dragon Fafnir stands at the centre of the greatest hero-legend of the Germanic world. It gave the German epic its hero Siegfried, gave Richard Wagner the spine of his Ring cycle, and gave J.R.R. Tolkien — who loved this tale above almost all others — the shape of more than one dragon in his own books.

And yet, for all its monsters and magic swords, the tale is not really about a dragon. It is about gold — about a treasure so cursed that it turns a son against his father, a brother against a brother, and a dragon against the whole world. The monster is only the form the greed takes.

A Legend Preserved in Verse and Saga

The story of Sigurd and Fafnir survives in several interlocking medieval sources, and they do not always agree, which is part of its richness. The oldest are the heroic poems of the Poetic Edda, preserved in the great Icelandic manuscript known as the Codex Regius (GKS 2365 4to), written around 1270. Two poems in that book carry the heart of our tale: Reginsmál, “The Lay of Regin,” which tells of the cursed gold and the broken sword, and Fáfnismál, “The Lay of Fafnir,” which tells of the dragon’s death and its dying words. Neither poem is actually named in the manuscript; medieval scribes simply ran the verses together, and modern scholars assigned the titles for convenience.

The fullest connected version is the Völsunga saga, an Icelandic prose saga of the late thirteenth century that gathers the whole sprawling legend of the Völsung family into a single narrative — and which becomes especially valuable because the Codex Regius suffers a famous accident: eight leaves have been lost from the middle of the manuscript, the so-called “Great Lacuna,” and the saga preserves in prose much of what those vanished pages once held in verse. A further account of the cursed treasure appears in the Skáldskaparmál section of Snorri Sturluson’s Prose Edda, written around 1220. The same legend travelled south into Germany, where it became the tale of Siegfried in the Nibelungenlied — one of the most widely diffused hero-stories in all of European tradition.

Folklorists recognise in it one of the most universal of all story patterns: the dragon-slayer who wins a guarded treasure. But the Norse version adds something darker and more particular to the pattern. Here the treasure is not a reward. It is a curse, and the curse is the real engine of the plot.

Sigurd, Regin, and the House of Hreidmar

At the centre stands Sigurd, last and greatest of the Völsungs. His father, King Sigmund, fell in battle before Sigurd was born, and the boy was raised at the court of another king, fostered and tutored by a smith named Regin. Sigurd grows up brave, open-hearted, and dangerously trusting — a hero with every gift except suspicion.

Regin is the more complicated figure, and to understand him you must know his family. Regin had two brothers, Otr and Fafnir, and a father named Hreidmar. They were not quite gods and not quite men — a household of shape-shifters and craftsmen on the edge of the magical world. That household was destroyed by a single piece of cursed gold, and Regin has spent his long life since then nursing one ambition: to get the treasure back. He cannot face the dragon himself. So he has raised a hero who can — and that, not kindness, is why Sigurd has a foster-father at all.

Beat One: The Otter’s Ransom and the Cursed Gold

The trouble was born long before Sigurd, on a day when three of the gods — Odin, Hœnir, and Loki — were walking by a waterfall. There they saw an otter on the bank, eating a salmon with its eyes half shut. Loki, who could never let a target alone, killed the otter with a single stone and was pleased with himself for taking both otter and fish at one throw. But the otter was no otter. It was Otr, a son of Hreidmar, who liked to take that shape to fish. When the gods came that night to Hreidmar’s house carrying the skin, the family seized them, and Hreidmar set the price of their freedom: they must fill the otter’s skin with gold, and then cover it entirely, until not one hair showed.

Loki was sent to find the gold, and he found it the quickest way he knew — by robbery. He caught a dwarf named Andvari, who lived as a pike in the water and possessed a great hoard, and he stripped him of every coin. Andvari begged to keep one last ring, for the ring had the power to breed more gold. Loki took even that. And so the dwarf, ruined, laid a curse upon the ring and upon the whole hoard: it would be the death of every owner who ever held it. The gods paid the ransom. They filled the skin and covered it — and Odin, who had wanted that breeding-ring for himself, had to surrender it last of all to hide a single whisker. The curse was now loose in the world, and it began its work at once. Hreidmar would not share the gold; so Fafnir, his own son, killed him for it, drove his brother Regin away empty-handed, carried the hoard to a lonely heath, and there, brooding over it, slowly turned into a dragon — a vast serpent who lay upon the gold and called the whole heath his own.

Beat Two: The Reforging of the Sword Gram

This is the wound Regin has carried for a lifetime, and Sigurd is his instrument of revenge. Regin tells the young man the story of the gold — though not, of course, the whole of it — and fires him with the idea of killing the dragon and winning the most famous treasure in the world. Sigurd agrees, on one condition: he must have a sword worthy of the deed.

Twice Regin forges a blade, and twice Sigurd tests it by striking the smith’s anvil, and twice the sword shatters. Then Sigurd goes to his mother and asks for the only inheritance that matters — the broken pieces of Gram, the sword that had been his father Sigmund’s, snapped in the battle where Sigmund died. Regin takes the shards and forges them anew, and this time, when the reforged Gram comes down on the anvil, it splits the iron to the base and the blade is unmarked. To prove it further, Sigurd lays a tuft of wool in a running stream and lets it drift against the edge, and the sword shears the wool clean in the current. The weapon is ready. The broken inheritance has been made whole, and a hero now carries his father’s sword to a fight his father never lived to see.

Beat Three: The Slaying of Fafnir

Regin guides Sigurd to Gnitaheid, the lonely heath where the dragon lies, and gives him a coward’s counsel: dig a pit in the track the serpent uses to crawl down to the water, hide inside it, and stab upward into the soft belly as the dragon passes overhead. It is not a glorious plan, and the poems hint that Regin half hoped the venom would kill Sigurd in the trench. But Sigurd, before he digs, is met by an old one-eyed stranger — Odin in disguise — who gives him better advice: dig more trenches, so the dragon’s scalding blood can drain away and not drown the man below.

Sigurd takes the wiser counsel, digs his pits, and waits. When Fafnir crawls down to drink, the earth shaking under him and his venom spattering the ground, Sigurd drives Gram upward with all his strength, straight into the dragon’s heart. The great serpent thrashes and rolls in its death-throes — and then, dying, it speaks. Fafnir asks the hero his name and his lineage, and the two hold a strange, grave conversation in the ruin of the dragon’s strength. And here the monster does something monsters rarely do: it tells the truth. Fafnir warns Sigurd that the glittering hoard is cursed, that it will be the death of whoever owns it — and that Regin, the man who sent him here, will betray him. The dying dragon, who was destroyed by exactly this gold, becomes the story’s most honest voice.

Beat Four: The Language of Birds

Regin now creeps back to the dragon’s body. He drinks some of Fafnir’s blood, and he asks Sigurd to do him one service: to roast the dragon’s heart on a fire so that he, Regin, may eat it. Sigurd, still the trusting foster-son, agrees. As the heart cooks, he touches it to see whether it is done, and the hot juice scalds his finger; he puts the finger in his mouth — and the moment the dragon’s blood touches his tongue, the world changes. He can suddenly understand the speech of birds.

In the branches above him, nuthatches are talking, and they are talking about him. They say that Sigurd is a fool to trust Regin; that Regin means to kill him the moment the heart is eaten and keep the gold for himself; that the wise thing, the only safe thing, is to strike first. Sigurd listens to the birds, weighs them against the dragon’s dying warning, and finds that the two agree. He rises, and before Regin can act, he strikes off the smith’s head. Both brothers of that doomed house are dead now, killed by their own hunger for the hoard. Sigurd eats a portion of the dragon’s heart, loads the cursed gold — Andvari’s ring among it — onto his great horse Grani, and rides away the most famous hero in the North, carrying a treasure that the dragon, with its last breath, swore would kill him.

The Moral: The Treasure That Eats Its Owners

It is tempting to read this as a simple triumph — brave youth kills monster, wins gold — but the tale refuses to let us. Every figure who touches Andvari’s hoard is destroyed by it, and the story is careful to show the chain. Andvari is robbed and curses the gold. Hreidmar takes it and is murdered by his son. Fafnir takes it, murders for it, and is so consumed by the wish to possess and guard that he literally stops being a person and becomes a dragon — the perfect image of what greed does to a soul. Regin schemes a lifetime for it and is beheaded the moment it is within reach. The gold does not need the dragon to do its killing. The dragon is only the most visible victim.

That is the myth’s hard centre: greed is a curse that the greedy carry inside them. Fafnir is not punished by the gods or by fate; he is punished by his own hunger, which narrows him, scales him over, and chains him to a heath he can never leave because he can never stop guarding. A man who cannot share, the tale says, slowly becomes a creature who cannot do anything else. And the warning is doubled by who delivers it. The most reliable counsel in the whole story comes from the dragon — the being most ruined by the gold — and Fafnir’s dying words are as plain as a warning can be:

Ræð ek þér nú, Sigurðr,
en þú ráð nemir,
ok ríð heim heðan;
it gjalla gull
ok it glóðrauða fé,
þér verða þeir baugar at bana.

“I counsel you now, Sigurd — and take you the counsel — ride home from here; the ringing gold and the glowing-red treasure, those rings will become your bane.” — Fáfnismál

Sigurd hears it. He even believes it — he uses the dragon’s warning, confirmed by the birds, to save his own life from Regin that very hour. And then he loads the cursed gold onto his horse and rides away with it anyway. That is the quietly devastating truth at the end of the tale: knowing a thing is poison is not the same as being able to put it down. The hero who is wise enough to understand the speech of birds is still not wise enough to leave the treasure on the heath. The curse rides home with him, and the rest of the Völsung legend — sorrow upon sorrow — is simply the curse keeping the dragon’s promise.

The Curse Rides On

The dragon-slaying is, in a sense, only the opening of a much longer tragedy, and that is worth knowing if the moral is to land with its full weight. In the wider Völsunga saga, Sigurd rides on from the heath to wake the warrior-woman Brynhild from an enchanted sleep, and the two pledge themselves to each other. But the cursed gold draws him into the hall of the Gjukungs, a powerful family who give him a potion that makes him forget Brynhild and marry their daughter Gudrun instead. Sigurd is then tricked into winning Brynhild as a bride for another man. When the deception unravels, the result is exactly what Andvari and Fafnir promised: jealousy, broken oaths, and Sigurd’s own murder, struck down by people he trusted, for the sake of the hoard.

The story does not stop even there. The treasure passes to the Gjukungs, who are themselves destroyed by it in a later generation, until at last the gold is sunk in the Rhine to keep it from doing further harm. Seen whole, the killing of Fafnir is not the tale’s climax but its hinge: the moment a single hero takes the cursed gold into his keeping and, by doing so, hands the curse a future. Everything sorrowful that follows in the greatest of the Norse hero-legends flows from the decision Sigurd makes on the heath — to ride home with the treasure rather than leave it where it lay.

Why the Tale Has Lasted

Sigurd and Fafnir has survived for the better part of a thousand years, and its reach is extraordinary. It is carved on Viking-age rune-stones — the famous Ramsund carving in Sweden shows Sigurd in the pit, the roasting heart, the burnt thumb, and the talking birds, a comic-strip in stone older than any surviving manuscript. It became Siegfried in the German Nibelungenlied. It gave Wagner the dragon Fafner and the cursed ring of his Ring cycle. And it shaped Tolkien’s imagination so deeply that the conversation between Bilbo and Smaug in The Hobbit is, in its bones, Sigurd and Fafnir once more.

It lasts because it works on two levels at once. On the surface it is a perfect adventure: the fatherless boy, the broken sword made whole, the buried inheritance, the monster in its lair, the magical gift of understanding birds. Those images are clean and strong and never grow old. But underneath runs the harder story, and that is the one that keeps the tale honest. The dragon on the gold is the oldest and truest picture of greed ever drawn — a creature that has so completely become its possessions that it has nothing left to be. Every age recognises Fafnir, because every age has watched someone curl up around a hoard and slowly turn into something less than human. The myth gave the world its greatest dragon-slaying. It also gave the world a mirror, and a warning the dragon itself was honest enough to speak: the ringing gold will become your bane — ride home without it, if you can.
