Scaphism

Scaphism (from Greek σκάφη, meaning "boat"), also known as the boats, is reported by Plutarch in his Life of Artaxerxes as an ancient Persian method of execution. He describes the victim being trapped between two small boats, one inverted on top of the other, with limbs and head sticking out, feeding them and smearing them with milk and honey, and allowing them to fester and be devoured by insects and other vermin over time. Plutarch's report originates from a source considered dubious.
