Sleipnir was the eight-legged horse of Odin — the swiftest and finest of all steeds, able to gallop over land, sea and sky and to carry his rider even into the realm of the dead, and the strange offspring of the trickster Loki. The greatest of all horses in Norse myth, he is the All-Father's mount, bearing Odin between the worlds on his eight tireless legs.
The Eight-Legged Steed
Sleipnir (Old Norse Sleipnir, “the slipper” or “the gliding one”) was the horse of Odin, and the finest horse among gods and men — grey, mighty, and uniquely possessed of eight legs, which made him faster and surer than any ordinary steed. He could gallop across the land, over the sea, and through the air, and he could carry his rider into any of the Nine Worlds, even down the long dark road to Hel, the realm of the dead. He bore runes carved upon his teeth, and he was the swiftest creature in all the worlds, the steed worthy of the king of the gods.
The Strange Birth
Sleipnir's origin is one of the most curious tales in Norse myth. When a giant builder offered to build the great wall of Asgard in exchange for the goddess Freya, the sun and the moon — a price the gods would never willingly pay — the gods agreed only on the impossible condition that he finish in a single winter with no help but his stallion, Svadilfari. But the mighty stallion hauled stone so swiftly that the builder neared completion in time, and the gods, facing disaster, blamed Loki, who had advised the bargain. To undo it, Loki transformed himself into a mare and lured the stallion Svadilfari away into the woods, so that the builder could not finish his work and lost the wager. And from that union — Loki the mare and the stallion Svadilfari — Loki later gave birth to a foal: the grey, eight-legged Sleipnir, whom he gave to Odin. Thus the trickster, in mare-form, was the mother of the All-Father's great steed.
The Ride to Hel
Sleipnir's ability to cross between the worlds made him essential to the gods' dealings with death. When the shining god Baldr was slain and the gods sought his return, it was upon Sleipnir that the messenger Hermod rode — galloping for nine nights down the dark road to the realm of Hel, leaping clean over the towering gates of the dead, to beg for Baldr's release. No other horse could have made that journey; only the eight-legged steed could carry a rider living into death and back. Odin too rode Sleipnir on his many journeys across the worlds, and into battle.
The Greatest of Steeds
Sleipnir endures as the most famous horse in all of myth — the eight-legged grey steed of Odin, swift beyond all others, able to cross land, sea, sky and the boundary of death itself, born of the shape-shifting Loki. He embodies the Norse vision of Odin as the rider between the worlds, the god who travels everywhere and sees everything, and he remains one of the most striking and beloved images of Norse mythology: the eight-legged horse galloping through the sky with the All-Father on his back.
Born of the trickster in mare-form, the eight-legged grey horse carries the All-Father across land, sea and sky — and is the only steed that can gallop living into the realm of the dead and back.
