This metal bull was the most heinous crime of torture known to humans throughout history, where the victim is placed inside the belly of the hollow bull and then heated down. When the body of the metal bull is heated, the victim screams during the evaporation of his body. The bull produces a sound known as the bull's baton that does not stop until the victim's body evaporates.
Torture takes place in 5 steps:
1 The victim is placed inside the bull's belly from the door in the above.
2 The fire is lit below the bull's belly after the upper door is closed.
3 The bull turns into an oven and the victim becomes a barbecue cooked on low heat between cries that diminish when his body begins to evaporate.
4 The bull begins to issue the sounds of "bull bounty" through the tubes turning the scream of the victim and burning it to sounds coming out with smoke from the mouth of the bull.
5 When the scream rises, the sound sounds like a screaming monster.
This terrible means of torture was used by the Catholic Inquisition in Spain against the Muslims of Andalusia after its fall. It was the means of Spain's Crusader kings who preferred to exterminate Muslims from Spain.
