Brazen bull

[Dorothey Allen]

A particularly nasty torture/execution device.
A hollow bull is cast entirely out of brass with a door on the side. After the [condemed] was placed inside, the door was closed and a fire was set underneath the bull. This caused the bottom of the bull to become red-hot and thus burning/roasting the victim.
The head of [the ox] was designed with a complex system of tubes and stops so that the [prisoners] screams were converted into sounds like the bellowing of an infuriated bull.
