This NorseAmerica Knight Lewis Chessmen piece is an exact replica of an authentic 900-year-old Viking chess set. This true-size piece is cast directly from the original Lewis chessmen, the most famous chess pieces in history. This is the same exact piece used in our Viking Isle of Lewis chess set. It measures approximately 3.5" tall and is sold as a single piece- i.e. 1 Knight piece from the white army as shown in the photo.
