Then there is 'tied neck and heels', where the victim was bent backwards as far as possible, then secured by a rope between the ankles and neck. Pressing, where the victim is tied down and a board placed over them on which weights are placed until the victim suffocates.
And of course, there is also the supposed Norse rite called the 'Blood Eagle'. A method of sacrificing a defeated enemy to Odin. The victim, who must be of Royal blood, was laid face down and a crude image of a spread-winged eagle was carved into the skin of his back. Then the ribs were separated from the spine with a blade, one by one, and all the time trying to ensure that the victim was kept alive. The skin and tissue was then peeled back and the ribs spread apart. Finally, the lungs were pulled out, which was supposed to be the point at which the victim finally died. There is considerable doubt as to whether this practice ever existed, but it is mentioned several times in the dark fantasy fiction of David Gemell.
