National Museums Scotland, 2010, 2011. – 80 p., ill.A popular reworking of a scholarly article from Medieval Archaeology, providing an overview of the chessmen found on the Scottish island of Lewis in the early 19th century, with some hypotheses about their provenance and origins, supplemented with colour illustrations.
History of finding is illustrated. Description of the isle of Lewis is made.
