Iron Maiden
The history of torture records many devices that worked on the principle of the anthropomorphic container with two doors, fitted with spikes on the inside that pierced the victim upon the doors being shut. The most famous example is the so-called “Iron Maiden” of Nuremberg, destroyed in the air raids of 1944. Probably the spikes of that time were movable among various sockets drilled into different places on the inside, according to the needs of the sentence.
