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.

the most painful tourture i think would have been what the mafia used to do to get information they would take a sewer rat put it on ur belly put a bucket over it and heat the buckets top matking it wear the rat is getting to hot and looking for somewhere to get out so they chew a whole slowly in ur stomatch and u can live from it being done 3 times becuase after 3 times it gos all the way through

There is no "most horrendous" there are a lot of absolutely horrible ones.

The Iron Maiden.

Rap Music!

I believe that the russian mafia has the two most horrendous. First, they will strap an iron onto your body, turn it on, and then leave for about ten minutes. Then they come back, give you time to recover, and then do the same thing on a different part of the body. You could imagine that you would be a well done steak all over in no time. Second method is that they will cut off your appendages one by one, but after each one, they sear off the wound either with a blow torch or an iron. After each toe and finger has been removed, they go for bigger things like hands, forearms, and lower legs. However, they usually don't make it that far since you will give up the dirt long before that. Lastly, this one is medieval. I think it was called scarphism. First they force feed you with enough milk and honey to induce severe diarrhea. Then you are strapped face up on a boat and set afloat in a pond. Beforehand, they put honey on your genitals, armpits, and face. Then insects are attracted by the diarrhea and honey. Next, they eat at your skin, burrow in, and breed on the inside. I don't think anyone has topped any of these.

Depends on the person. Some people have a higher tolerance for pain than others, so an emotional torture might be worse to them. That is why torture is a progressive thing. You find the persons weakness, then exploit it.

Stuff from that Hostel movie.... ugh!

I will go with the Iron Maiden. It gives me the chills just thinking about it.
