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.
The first mention of scaphism is Plutarch's description of the execution of the soldier Mithridates, given as punishment by king Artaxerxes II for killing his brother Cyrus the Younger, who had rebelled in an attempt to claim the throne of the Achaemenid Empire: [The king] decreed that Mithridates should be put to death in boats; which execution is after the following manner: Taking two boats framed exactly to fit and answer each other, they lie down in one of them the malefactor that suffers, upon his back; then, covering it with the other, and so setting them together that the head, hands, and feet of him are left outside, and the rest of his body lies shut up within, then forcing him to ingest a mixture of milk and honey before pouring all over his face and body.
And as within the boats he does what those that eat and drink must needs do, creeping things and vermin spring out of the corruption and rottenness of the excrement, and these entering into the bowels of him, his body is consumed.
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.
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.It is believed that Plutarch's account of Scaphism came from Ctesias, a Greek physician and historian.
