Here we have something really special. The Hand of Glory is the dried and pickled hand of a man who has been hanged, often specified as being the left hand, or else, if the man was hanged for murder, the hand that did the deed.
According to old European beliefs, a candle was made with the fat of one who had died on the gallows, virgin wax, and Lapland sesame oil, this was combined with a hand having come from a hanged criminal. Once it was lit it would have rendered motionless all persons to whom it was presented. The Hand of Glory also purportedly had the power to unlock any door it came across. Because of this the Hand was sometimes used by burglars to rob houses.
