The Lewis Chessmen Unmasked exhibition in Edinburgh brings together the British Museum and the National Museum of Scotland’s collections of the Lewis Chessmen – a set of medieval gaming pieces, originating most likely from Trondheim in the 12th or 13th century, which were discovered on the Hebridean island of Lewis sometime between 1780 and 1831.

Individually hand-carved from walrus ivory, and numbering 93 pieces in total – 82 of which are held by the British Museum, the remaining 11 by the National Museum of Scotland – the Lewis Chessmen are world famous for their mysterious origins, unique design and curious, almost comical expressions, which range from moody kings to a frightened-looking warder biting down on his shield. They even made a cameo in the film Harry Potter and the Philosopher’s Stone.
