What is a bull roarer?

The so-called bull roarer was found at Kongemosen on Zealand. This musical instrument consists of a worked piece of a bone. The outline is a pointed oval, and a hole has been bored into one end, through which a piece of string could be threaded. Swinging it in the air produced a humming sound. As the object is unique in Denmark its function has also been frequently debated. Could it have been a fish trap or a weaving tool? It is certainly believed that the hole was for attaching a string. This was tried when one of the archaeologists, inspired by a parallel find from northern Germany, swung the piece round in the air. Then something peculiar happened! The object produced a sound, which had not been heard for 8000 years.
