"The brazen bull is an execution/torture device designed in ancient Greece. Perillos of Athens, a brass-founder proposed to Phalaris, Tyrant of Agrigentum, the invention of a new means for executing criminals; accordingly, he cast a brazen bull, made totally of brass, hollow, with a door in the side. The condemned was shut up in the bull and a fire was set under it, heating the metal until it became "red hot" and causing the person inside to slowly roast to death. So that 'nothing unseemly might spoil his feasting', Phalaris commanded that the bull be designed in such a way that its smoke rose in spicy clouds of incense. The head of the ox was designed with a complex system of tubes and stops so that the prisoner's screams were converted into sounds like the bellowing of an infuriated bull. "
