Scaphism - Wikipedia
"Two boats are joined together one on top of the other, with holes cut in them in such a way that the victim's head, hands, and feet only are left outside. Within these boats the man to be punished is placed lying on his back, and the boats then nailed together with bolts. Next they pour a mixture of milk and honey into the wretched man's mouth, till he is filled to the point of
nausea, smearing his face, feet, and arms with the same mixture, and so leave him exposed to the sun. This is repeated every day, the effect being that flies, wasps, and bees, attracted by the sweetness, settle on his face and all such parts of him as project outside the boats, and miserably torment and sting the wretched man. Moreover his belly,
distended as it is with milk and honey, throws off liquid excrements, and these putrefying breed swarms of worms, intestinal and of all sorts. Thus the victim lying in the boats, his flesh rotting away in his own filth and devoured by worms, dies a lingering and horrible death."
