The following are the 20 worst torture devices of all time in order of sheer terror:

20. Punishing Shoes
The shoes were often used in conjunction with the standing pillory (a device that holds your head and wrists in place while you stand). How long do you think you could stand on your tippy-toes before you had to rest your heels on those iron spikes?

19. Heretic's Fork
The four sharp points snugly nestled under the chin and sternum were designed to allow the victim just enough range of motion with his mouth to murmer a confession.

18. Dunking Stool
Used primarily on women (as was the case for most devices of pseudo-sexual torture), the dunking stool would dip its occupant into a river for as long as the authorities saw fit.

17. The Boots
The victim's legs were placed between two planks of wood and bound together with cords. Between the cords the torturers placed wedges with which they would violently hammer. Each time a wedge was hammered, an acute portion of the shin bone was shattered. The tormentors could hammer at least a dozen wedges up and down the legs. When the Boots were removed, the bone fragments fell to pieces and the skin of the lower legs merely served as loose sacks for them.

16. Water Torture
This is the only non-medieval, European torture on our list. The water torture was a favorite among Japanese POW guards during WWII. The victim was first bound with barbed wire and his mouth stuffed with rags. Next, the guards would snake a tube down the victim's nasal passage and bloat his belly with water. Once that was finished, the guards would kick and beat the poor sap's midsection until his stomach lining burst and and death ensued.

15. Cat's Paw
This was simply used to slowly tear the flesh from its victim, often times all the way down to the bone.

14. The Rack
It does exactly what it looks like it does: the rack pulls your body from end to end until your limbs are slowly plucked from their joints.

13. Quartering by Horses
Quartering is the rack taken to the next level and was reserved only for murderers and those who killed or attempted to take the life of a nobleman or royalty. Each of the prisoner's limbs were tied to a horse and the horses were whipped simultaneously so that each limb would erupt from the body in an instant. A crowd favorite.

12. The Pear
Hinging on your gender, the pear was either placed in your anus or your vagina in its thin form and then cranked to open up and blossom into a rather uncomfortable position.

11. Cleansing the Soul
In many Catholic countries, the clergy believed that the corrupted soul of a damned person could be cleansed if they were forced to consume boiling water, burning coals, or both. Of course, this was what happened to prisoners before they were punished for their crime -- sort of a "warm-up" torture, if you will.

10. The Hanging Cage
The pictured victim is one of the lucky ones because most occupants were caged completely naked to expose them to either extreme cold or hot weather conditions. And... most caged prisoners were usually placed in there only after other means of extreme physical torture were administered. But wait -- there's more! The victims were left in the cage until they died from either the elements or thirst, which could take weeks.

9. The Head Crusher
If ever an explanation was in a name, the head crusher is it. Death by head crusher usually went something like this: the teeth imploded into their sockets and smashed the surrounding jaw bones. Then the eyes squirted from their sockets and finally, brain matter squirted from the ears. Unbelievably, many nations still use a version of the head crusher to this very day as an interrogation tool.

8. Burning at the Stake
A favorite execution for those accused of witchcaft. Clergy believed that the burning of a witch permanently removed her evil spirits from the physical world, thus eliminating the possibility of any further contamination of innocent souls. Makes sense.

7. Judas Cradle
The victim was hoisted above the pyramid and slowly lowered, crotch first, onto its sharpened pinnacle. Hinging on the torturers mood, he could vary the amount of the victim's body weight applied to the point.

6. The Cradle
The Cradle is the nastier second cousin to the Judas Cradle. We believe the picture does all the explaining for us.

5. Iron Maiden
The following is a depiction of the first recorded use of the Iron Maiden on August 14, 1515 : "A forger of coins was placed inside, and the doors shut slowly, so that the very sharp points penetrated his arms and legs in several places, and his belly and chest, and his bladder and the root of his member, and his eyes, and his shoulders, and his buttocks, but not enough to kill him; and so, he remained making great cry and lament for two days, after which he died."

4. Interrogation Chair
Not only were the hundreds of tiny spikes uncomfortable to sit on, but a fire was usually kindled under the iron chair to make it reach a horrible scalding point.

3. Impalement
This was the standard form of punishment for traitors in Algiers, Tunis, Tripoli and Salee during the Middle Ages. Believe it or not, once the lengthy spike entered the victim's posterior and exited their mouth or throat, the victim might live for more than a day in this state and was left to crawl in the dirt for all to watch.

2. The Saw
The saw may represent human ingenuity's darkest hour. The idea here is that when the victim is suspended upside down, most of the blood will go to the head. That is an important part of the process, you see, because as the torturers saw into the victim's crotch, all of the blood in the head will oxygenate the brain so that the victim will not pass out as one normally would under such excruciating pain. Typically, the saw would reach the victim's navel before unconsciousness would take hold -- sometimes as far as the midriff.

1. Breaking with the Wheel
Okay, we've saved the most treacherous display for last. So, if you've had trouble with any of the above and want to turn back now, no one will think less of you for it................ You still here? You sick bastard. Okay, here we go... In terms of frequency used, the wheel was second only to hanging as the most common form of execution in Germany during the Middle Ages. First, the victim (usually naked) had each of his limbs spread apart and tied to the ground. However, wooden crosspieces were placed under each major joint such as the wrists, ankles, knees, hips and shoulders. The torturer would then smash each limb and joint with the heavy, iron-enhanced wheel. But that was just the beginning of the nightmare. Once the limbs were reduced to gelatinous appendages of mashed bones, blood and flesh, each arm and leg was braided into the spokes of the wheel and then hoisted upright for display. The agonizing victim would remain in this position for days as crows and insects feasted on him or her until death.
