How does an iron maiden torture device work?

An iron maiden is a torture device that consists of a coffin-like structure with spikes on the interior. When a victim is enclosed inside and the device is closed, the spikes pierce the body, causing severe injury or death. The design allows for both physical pain and psychological torment, as the victim is often aware of their impending fate. Its historical use is debated, with some suggesting it may have been more symbolic than practical.
