One of the most gruesome torture methods, flaying promises hours of agony and pain. Being flayed alive is almost as painful as being burned alive. Skinning a person is an ancient practice to torture or execute a person. Some tribes, like the Aztecs of Mexico, flayed their victims as part of their rituals for human sacrifice. On the other hand, in Medieval Europe, traitors were executed by being skinned alive in public. There are many ways to flay a person; some would directly remove their victim’s skin or flesh, while others would pour boiling water on their victim’s skin to make the flaying easier. Either way, the pain was unbearable considering that the victims were alive during the process.
