Hand of glory

Are you familiar with the concept?  An old pub near where I live had long been reputed to be haunted and during renovation in the late 19th century a mummified hand and arm was discovered in a chimney.  And it created a lot of interest at the time because it was said to be a "hand of glory".  According to medieval folklore if you cut off the hand of a criminal who had been hanged on the gallows, and pickled it, it would have miraculous qualities, main among which was the ability to stupefy anybody who saw it. As such, such an object was prized by burglars who would use it to (hopefully) petrify the members of the house they were robbing.  The arm is now in the local museum - its provenance is still somewhat of a mystery, although it has been established that it had been injected with formalin, which suggests it was some sort of medical specimen.
