Boiling Not just reserved for cannibalistic tribes, boiling was actually on the records as a legal method of execution in England during the reign of Henry VIII. It was used mostly for those who murdered by poison. The first victim of legal boiling in England was Richard Rouse, a cook.
Boiling was also popular as a slow torture-execution among various sects. Victims could be submerged in heated water, oil, pitch, wax, or even molten lead.
