Frequently asked questions

Sleipnir is the eight-legged horse of the god Odin, regarded as the best of all horses across the nine worlds. The key thing to remember is that his importance goes far beyond simply being a mount: he symbolizes Odin's ability to travel between the worlds — on land, on sea and through the air — and he is the only one able to cross the gate of the realm of the dead. In the poem Grímnismál, he is even named “the best of horses,” just as Yggdrasil is the best of trees. This place in the Norse ranking of the “best” shows just how central he is to the Viking imagination.

Anecdotes

Sleipnir has a very strange birth: to prevent a giant builder from finishing the walls of Asgard too quickly, the god Loki turns himself into a mare and lures away the giant's stallion, Svaðilfari. Some time later, Loki gives birth to a grey, eight-legged foal: this is how Sleipnir is born, one of the rare cases in mythology where a male god gives birth.

His most famous feature is that he has eight legs, making him the fastest horse in the nine worlds. An eight-legged horse can be found carved on Scandinavian stones such as the Tjängvide stone, on the Swedish island of Gotland (8th-9th century), proof that this image circulated long before it was written down.

After the death of the god Baldr, it is Sleipnir who is chosen for the most dangerous mission: the messenger Hermóðr rides him and gallops for nine nights through dark valleys to the realm of the dead. Before the gate of Hel, Sleipnir gathers his momentum and leaps over it with a bound so powerful that he does not even touch it.

In the poem Grímnismál, Sleipnir is named “the best of horses,” just as Odin is the best of gods, the ash tree Yggdrasil the best of trees, and Bifröst the best of bridges. Being the “best” of one's category was a typically Norse way of ranking the world.

Sleipnir is not just a fast horse: according to the poem Sigrdrífumál, magical runes were said to have been carved on his teeth. The horse thus becomes a vessel of secret knowledge, able to carry Odin over land, over sea, and through the air, between the nine worlds.

Primary Sources

Snorri Sturluson, Edda (Gylfaginning) — the birth of Sleipnir (c. 1220)
Loki had had such dealings with Svaðilfari that some time later he gave birth to a foal. It was grey and had eight legs; it is the best horse among gods and men.
Poetic Edda, Grímnismál (stanza 44) (Codex Regius manuscript, c. 1270 (older poem))
Just as the ash Yggdrasil is the foremost of trees and Skíðblaðnir the foremost of ships, Odin the foremost of the Æsir, so Sleipnir is the foremost of horses.
Snorri Sturluson, Edda (Gylfaginning) — the ride to Hel (c. 1220)
Hermóðr rode for nine nights through valleys so deep and so dark that he could see nothing; then Sleipnir leapt over the gate with such force that he never touched it.
Poetic Edda, Sigrdrífumál (stanza 15) (Codex Regius manuscript, c. 1270)
Runes were carved in many secret places — and some were also carved on Sleipnir's teeth.
