” The historic political, economic and cultural links between the Outer Hebrides and Norway and its dominance of the Norse world might suggest that Norway is the most likely place to have produced these high status, luxury commodities” (British Museum Website: The Lewis Chessmen)
Certainly the chessmen show strong evidence of Norse culture, particularly in the several ‘warders’ – the equivalent of the modern ‘rook’ – which take the form of Berserkers biting their shields.
Records of the time state that some of the pieces were stained red, although this has now faded.
Altogether, 94 Lewis Chessmen are known: 82 of them are in the British Museum and 11 are in National Museum of Scotland in Edinburgh. In 2019 another piece – a warder – was discovered See BBC news report here….
