The bullroarer,[1]rhombus, or turndun, is an ancient ritual musical instrument and a device historically used for communicating over great distances.[2] It consists of a piece of wood attached to a string, which when swung in a large circle produces a roaring vibration sound.
It dates to the Paleolithic period, being found in Ukraine dating from 18,000 BC. Anthropologist Michael Boyd, a bullroarer expert, documents a number found in Europe, Asia, Africa, the Americas, and Australia.[3] In Ancient Greece it was a sacred instrument used in the Dionysian Mysteries and is still used in rituals worldwide.[4] It was a prominent musical technology among the Australian Aboriginal people, used in ceremonies and to communicate with different people groups across the continent.
Many different cultures believe that the sounds they make have the power to ward off evil influences.
^Haddon, The Study of Man, p. 219: "Prof. E. B. Tylor informs me that the name of 'bull-roarer' was first introduced into anthropological literature by the Rev. Lorimer Fison, who compares the Australian tundun to 'the wooden toy which I remember to have made as a boy, called a 'bull-roarer',' and this term has since been universally adopted as the technical name for the implement." [Fison and Howitt, Kamilaroi and Kurnai, 1880. p. 267.]
^Gregor, Thomas. Anxious Pleasures: The Sexual Lives of an Amazonian People. University Of Chicago Press (1987). p. 106 "Today we know that the bullroarer is a very ancient object, specimens from France (13,000 B.C.) and the Ukraine (17,000 B.C.) dating back well into the Paleolithic period. Moreover, some archeologists—notably Gordon Willey (1971, 20)—now admit the bullroarer to the kit-bag of artifacts brought by the very earliest migrants to the Americas."
