In Norse mythology, Sleipnir is Odin's magical eight-legged steed, and the first of all horses. His name means smooth or gliding, hence the English word, slippery. Loki, in the guise of a mare, gave birth to Sleipnir.
It has been suggested that Sleipnir having eight legs is symbolic of the four men who carry a coffin, i.e. a steed to carry the rider into the underworld.
A stainless steel statue of Sleipnir is a prominent feature in the Midlands town of Wednesbury (which means Odin's fort).
