The Brazen Bull
Also known as the Sicilian Bull, it was designed in ancient Greece. A solid piece of brass was cast with a door on the side that could be opened and latched. The victim would be placed inside the bull and a fire set underneath it until the metal became literally yellow as it was heated. The victim would then be slowly roasted to death all while screaming in agonizing pain. The bull was purposely designed to amplify these screams and make them sound like the bellowing of a bull.
