Such a device was reputed to have been used by Geoffrey Chaucer. The levels of scoring achievable with this early model do not reach nearly the values possible today. See Popular Linguistics Mercenary, Vol. XI, Nr. 2 (February - March Double Issue) for a number of articles about how to construct your own working prototype.

It is possible that a device of this type was responsible for early 18th-century reports of Glimmstrahlen (glow rays) in isolated regions of the Harz Mountains, since one was almost certainly stolen from a collection in Quedlinburg in 1680.

No photographs of contemporary effects like this have turned up; the instrument in question is still missing.
