Death by sawing was the act of sawing a living person in half, either sawing the individual in half across or along the body length. Death by sawing was a method of execution reportedly used in different parts of the world, including the Roman Empire, Spain, and parts of Asia. The Thracian king Ziselmius sawed several of his subjects to death and commanded their families to eat the flesh of their murdered relatives. The Thracians eventually rebelled, captured him and inflicted every conceivable torture upon him. In 365 AD, Procopius declared himself Roman emperor and moved against his rival Valens. He was defeated in battle, and due to the treachery of his two generals Agilonius and Gomoarius (they had been promised they would be “shown favour” by Valens), he was captured and fastened to two trees bent down with force; when the trees were released, Procopius was ripped apart. The “favour” Valens showed to Agilonius and Gomoarius was to have them both sawn asunder.
