In
Norse mythology,
Sleipnir (
Old Norse "slippy" or "the slipper") is an eight-legged
horse. Sleipnir is attested in the
Poetic Edda, compiled in the 13th century from earlier traditional sources, and the
Prose Edda, written in the 13th century by
Snorri Sturluson. In both sources, Sleipnir is
Odin's steed, is the child of
Loki and
Svaðilfari, is described as the best of all horses, and is sometimes ridden to the location of
Hel. The
Prose Edda contains extended information regarding the circumstances of Sleipnir's birth, and details that he is grey in color.
