I saw this while browsing, having read a book where children get thrown into a brass bull with a furnace inside as sacrifices. It's a pretty novel and horrible way of dying.
http://en.wikipedia.org/wiki/Brazen_bullQUOTE
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 victim was shut up in the bull and a fire was set under it, heating the metal until it became "red hot" and causing the victim 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 supplied by a complex system of tubes and stops so that the prisoner's screams were converted into sounds not unlike the bellowing of an infuriated ox. It is also said that when the bull was reopened, the victims' scorched bones shone like jewels and were made into bracelets.
Ouch. If that wasn't enough, read what happened to Perillos:
QUOTE
Phalaris commended the invention, and ordered its horn sound system to be tested by Perillos himself. When Perillos entered, he was immediately locked in, and the fire was set, so that Phalaris could hear the sound of his screams.
Before Perillos could die, Phalaris opened the door and took him away. Perillos believed he would receive a reward for his invention; instead, after freeing him from the bull, Phalaris threw him from the top of a hill, killing him.
That's gotta suck.
If it's any consolation to Perillos, apparently when Telemachus overthrew Phalaris, he burnt him in his own bull as a kind of irony. Those Ancient Greeks sure came up with some interesting ideas.
