Impalement, as a method of execution, is the penetration of a human by an object such as a stake, pole, spear, or hook, often by complete or partial perforation of the torso. It was used particularly in response to "crimes against the state" and regarded across a number of cultures as a very harsh form of capital punishment and recorded in myth and art. Impalement was also used during wartime to suppress rebellion, punish traitors or collaborators, and as a punishment for breaches of military discipline.
