We’ve been fascinated by bodies found in European bogs since they were first recognized as ancient in the late 19th century. Clonycaven Man was discovered in 2003, fished up by a commercial sieve in a peat processing operation. His image is haunting. Lying on his side, with a rope around his neck, his abdomen sliced open, there is little mystery about how he died. Why is an entirely different question. New technology is now being applied to the study of Clonycaven Man and other bog bodies in an attempt to learn more about the preliterate Iron Age society that buried them. National Geographic has posted online an article by Karen E. Lange exploring these efforts, with photos by Robert Clark.
