Iron Maiden of Nuremberg (The).
An instrument of torture for heretics, traitors, parricides, etc. It was a box big enough to admit a man, with folding-doors, the whole studded with sharp iron spikes. When the doors were pressed-to these spikes were forced into the body of the victim, who was left there to die in horrible torture. (German, Eiserne Jungfrau.)
