Death by burning

Death by burning (also known as immolation) is an execution method involving combustion or exposure to extreme heat. It has a long history as a form of public capital punishment, and many societies have employed it as a punishment for and warning against crimes such as treason, heresy and witchcraft. The best-known execution of this type is burning at the stake, where the condemned is bound to a large wooden stake and a fire lit beneath.
