During the last decades of the 20th century, a number of rock carvings with unique motifs were discovered in western Sweden. The petroglyphs were of an unmistakable ancient character and seemed to provide a quite different image of Bronze Age society in Southern Scandinavia. Instead of the established archaeological picture of a strongly stratified society with focus on bronze and weapons the newfound carvings mediated a happy and harmonious vision of the period. The rock carvings were discovered by the one and same person who was a well-established amateur archaeologist specialised in finding previously unknown prehistoric petroglyphs and as such repeatedly employed by the Swedish National Heritage Board. Now it turns out that it by all accounts was he himself who made the unique petroglyphs in order to give a different picture of Bronze Age society. He chose a congenial way of expressing himself and his carvings are de facto petroglyphs that appear to repeal the chronological border between past and present. Today the carvings constitute an unruly heritage that is difficult to handle by archaeological research as well as cultural heritage management.
