It's an ancient Persian form of execution, also known as "the boats". The perp is laid down in a boat while another one is bolted to it, exposing his head, hands and feet to the elements. He's force fed a mixture of milk and honey, which is also smeared all over him to attrace all kinds of insects. Colonies of worms will form inside him,so literally he slowly rots to death.
Similar to the plains Indian method with ants.
Nice.
I'm partial to the ancient Chinese "Death by Inches" myself.
Drawn and Quartered the olde English Way, has a lot going for it, as well.
Too bad he couldn't suffer all three, one after the other.
