Intentional mummification is a practice usually associated with early Egyptian or Peruvian societies, but new evidence suggests that it may also have been widespread in prehistoric Britain, and possibly in Europe more generally. Following the discovery of mummified Bronze Age skeletons at the site of Cladh Hallan in the Western Isles of Scotland, a method of analysis has been developed that can consistently identify previously mummified skeletons. The results demonstrate that Bronze Age populations throughout Britain practised mummification on a proportion of their dead, although the criteria for selection are not yet certain.
