The Lewis Chessmen, named for the site of their discovery -- the Isle of Lewis in the Scottish                      Hebrides Islands -- were found in 1831.  93 of these charismatic little figures are known to                        exist, with 82 on display in the British Museum, and 11 on display in the National Museum                        of Scotland, Edinburgh.  Carved of whale tusk and whale bone, their origin is thought to                            be Scandinavian, circa 1175AD, but how they came to be buried in a sandbar in northwest                          Scotland is a mystery.
