Svaðilfari

The road up to the half-built wall was frozen hard enough to ring under a hoof, and every night that winter it rang. A stallion came down out of the dark hauling rock that no cart-team should have been able to shift, breath standing white around his head, the traces creaking, the sledge grinding behind him with a sound like a millstone. The wright who owned him walked alongside and said very little. The horse knew the way.

Svaðilfari has no cult, no hall, no epithet won in battle. He turns up twice in the medieval record and both times as somebody else’s property and somebody else’s father. What the sources hand him instead of glory is the strangest paternity in the North: he sired Odin’s eight-legged horse, and the mother was Loki.

It happened early, after the gods had set Midgard in order and raised Valhall, when a wright came to them with an offer. He would build a citadel in three seasons, so sound that neither hill-giants nor rime-giants could take it even if they came in over Midgard. His fee was Freyja, and he wanted the sun and the moon along with her. The Æsir took counsel, as they do, and came back with terms: one winter rather than three seasons, no help from any man, and if any part of the work stood unfinished on the first day of summer he would go home with nothing. It was Loki who talked them into that shape of bargain. The wright accepted, then asked for one thing. He wanted leave to use his stallion. Loki spoke up for that as well, and the request was granted.

He began on the first day of winter, and it was at night that the stones moved. Before long the Æsir found themselves watching the horse rather than the builder. Svaðilfari out-hauled his own master by a margin the translators still argue over, dragging blocks so large that the gods thought them worth remarking on, which from that company is close to applause. There were strong witnesses to the bargain and a great many oaths sworn over it, because the giant did not fancy standing about unprotected among the Æsir if Thor came home. Thor was away in the east, killing trolls.

By the tail of winter the citadel was so high and so strong that it could not be taken, and with three days left before summer the work had come almost to the gate. The gods sat down in their judgment seats and began asking one another whose idea it had been to hand Freyja over into Jötunheim and strip the sky of the sun and the moon. The answer was the one it usually is. They told Loki plainly that he deserved an ugly death unless he found some way to lose the wright his wages, and they did not put it gently.

That same evening the wright drove out after stone as he had every evening. A mare came out of the wood at the edge of the clearing and whinnied to him. Svaðilfari understood exactly what she was, went frantic, snapped the traces, and was over and after her into the trees. She ran, and he ran, and the wright ran behind them both trying to get a hand on his own horse. The three of them were still at it when the light came. In the morning the stone did not move as it had moved before.

Seeing that the work could not be finished, the wright fell into a giant’s fury, which settled any question about what he had been all along. The Æsir stopped being scrupulous about their oaths the moment they knew a bergrisi was standing inside them, and called for Thor, who came quickly. He paid the builder’s wage with Mjöllnir instead of with the sun and the moon, burst his skull into small crumbs at the first blow, and sent him down beneath Niflhel. Snorri lets a stanza of *Völuspá* carry the judgement on the broken oaths, because the gods had not come out of the winter clean and the poem knows it.

The mare, of course, had not been a mare. Some while afterwards Loki gave birth to a grey foal with eight feet, the best horse among gods and men, and it was Odin who rode him. Everything else about Svaðilfari serves that one fact. The older verse in *Hyndluljóð* states the paternity in four flat lines and offers no explanation at all, which suggests the arrangement was common knowledge long before Snorri sat down to make narrative sense of it.

Nobody describes him. Not his colour, not his height, not the set of his head. For an animal whose strength is the entire reason he enters the myth, that silence is striking, and it is also the ordinary fate of a working beast in a story about the people arguing over him. What can be pieced together is inference from what he does: quarters able to move building stone uphill night after night through a Scandinavian winter, tackle strong enough to hold that load and not strong enough to hold him once he had decided to leave, and enough left in his legs to run until dawn. The only colour anywhere near him belongs to his son, and the foal came out grey.

Where he came from is not said either. He belongs to a mountain-giant whom the sources never name, and the two of them arrive already paired, horse and master, out of a life the story has no interest in. The name is the single piece of characterisation the language provides. Svaðilfari is generally read as something like the one who makes an unlucky journey, built on a word for a slip or a mishap on the road. It fits the horse who ruined his owner and the owner who lost his head, and it reads less like a name than a summary of the outcome.

His powers are simple and physical. Strength past anything the gods had expected of a horse, stamina that held through a whole winter of night work, and speed enough to stay ahead of a furious giant until morning. Nothing about him is uncanny in the way his son is uncanny. He hauls, and he can outrun the consequences for exactly one night.

His weakness is the one the gods reached for, and calling it a weakness flatters it. He is a horse, and he behaves like one. Every oath, every witness and every clause about receiving no help from any man had been drafted around the wright, and none of it accounted for the animal doing the actual work, or for what that animal would do when something called to him from the trees. The wall still stands in the story, high and unbreachable and missing its gateway, and the horse who built most of it is never mentioned again.

Frequently Asked Questions

Who is Svaðilfari in Norse mythology?

Svaðilfari is the stallion belonging to the unnamed builder who contracted to wall Asgard for the gods. He hauled the stone for that wall by night, working faster than his own master, and he is best known as the father of Sleipnir, Odin’s eight-legged horse.

Is Svaðilfari really the father of Sleipnir?

Yes, and two separate medieval sources say so. Snorri Sturluson tells the full story in chapter 42 of *Gylfaginning*, and the older Eddic verse in *Hyndluljóð* states in passing that Loki got Sleipnir with Svaðilfari, without bothering to explain how.

Who owned Svaðilfari?

A wright who came to the gods offering to build them a fortification in three seasons in return for Freyja, the sun and the moon. He turned out to be a bergrisi, a mountain-giant in disguise, and Thor killed him with Mjöllnir once the deception was exposed.

How did Loki stop Svaðilfari from finishing the wall?

Loki turned himself into a mare and whinnied to the stallion from the edge of a wood while the builder was out fetching stone. Svaðilfari snapped his traces and chased her into the trees, and the two horses ran all night, so the night’s hauling was lost and the wall was left three days short of completion.

What does the name Svaðilfari mean?

It is usually translated as “the one making an unlucky journey” or “unlucky traveller”, from an Old Norse word for a slip or a mishap on the road. The reading suits the outcome, since the journey in question cost his owner both his wages and his life.
