@ anon260858: From what I have read, no account has been found earlier than 1793.
@ SilentBlue: You need to read something other than the Bible and history as Christians would like everyone to perceive it. Christianity used torture devices like the iron maiden (the Catholics used a mechanical effigy of the Virgin Mary) as well as many other horrific torture devices to dissuade heretics.
A 'heretic' could be anyone that maintained religious opinions contrary to those accepted by his or her church or rejects doctrines prescribed by that church. Since my parents had me join the Catholic church long before I had any choice in the matter and I do not consider myself a Catholic I would be considered a heretic. I am very thankful they no longer employ these methods.
There were many other horrifying devices used on heretics in medieval times as well as during the Spanish inquisition such as Breaking on the Wheel, the Pope's Pears, the Judas Cradle, the Iron Spider, the Strapado, the Cat's Paw, the Slow Burn, the Quick Burn, the Rack, the Holy Trinity. If you think that Christians were any less brutal than anyone else during that time, look those up and think again.
