This granite hammerstone was made for Norway's wonderful Arkikon Archaeology park. The granite river cobble was struck repeatedly with a harder quartz hammer to wear in a groove for hafting. It was then wrapped with a sapling of green oak and tightened with a plant fiber cord. The replica held up to heavy hammering in testing and still functions well.
The best way to view Upper Paleolithic cave art(around 15 to 17,000 BP) is in the light that they were painted in. Here a replica of the famous Lascaux oil burner was lit in front of a charcoal painting. This is the way it would have looked to the original artists in prehistory.
