13. The Brazen Bull
The Sicilian invention of the brazen bull is tied to many legends and is claimed to have been an invention for propaganda.
The brazen bull is said to have been designed with the precise measurements of a bull as well as designing its acoustic structure to convert the screams of victims to produce the sound of an infuriated bull.
The accused would be put through the door of the bull and locked inside, thereafter, a fire would be set under the bull which would roast the victim inside to ashes.
