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.
A stainless steel statue of Sleipnir is a prominent feature in the Midlands town of Wednesbury? (which means Odin's fort).
