In Norse mythology, Sleipnir (Old Norse "slippy" or "the slipper") is an eight-legged horse ridden by Odin. Sleipnir is the offspring of Loki (in the form of a mare) and the stallion Svadilfari. Sleipnir is described as the best of all horses, and is sometimes ridden to the location of Hel. Sleipnir is attested in the Eddas, compiled in the 13th century from earlier oral sources. Also, 8th-century images of an eight-legged horse have been found in Sweden.
