Point a spotlight at it, though, so that the face of the coin is illuminated from an acute angle, and the resulting shadows will emphasise any minor details. This is the basic principle behind a novel technique that is helping archaeologists reveal previously invisible clues hidden in the worn or damaged surfaces of any objects they uncover. From wall paintings in Herculaneum to Scandinavian stone tools to rock art in Libya, polynomial texture mapping, as the process is known, is proving an invaluable way to illuminate the past.
