Where did iron maiden's name come from?

Steve Harris, the band's bass player after watching the movie "The Man in the Iron Mask" was inspired by the torturing device called Iron Maiden which had a connection in the movie. An iron maiden is an iron cabinet with front doors on hinges. The doors and sometimes the back part and walls are covered with spikes. A person would be put in there for torturing purposes. As the doors would close, the person would be pierced. Many times with a fatal ending.
