A shitty way to die

From the Historiae Auguste, on Philip the Arab's murder of Timesitheus;

Philip, they say, was mightily in fear of him for many reasons and on this account plotted with the doctors against his life. He did it in this way: Timesitheus, as it happened, was suffering from diarrhoea and was told by the doctors to take a portion to check it. And then, they say, they changed what had been prepared and gave him something which loosened him all the more; and thus he died.
