The Lewis Chessmen, probably made in Norway, about AD 1150-1200. At this period, the Western Isles, where the chessmen were buried, were part of the Kingdom of Norway, not Scotland. It seems likely they were buried for safe keeping on route to be traded in Ireland.
Chess is said to have originated in the Gupta Period where its early form in the 6th century was known as [[chaturanga, which translates as "four divisions [of the military]" – infantry, cavalry, elephants, and chariotry – represented by the pieces that would evolve into the modern pawn, knight, bishop, and rook, respectively. @jessica zheng.wikipedia.org
