Carus may well have done some shocking things; electrified the people of Rome with his lightning speed and thunderous voice. He may have seen the storm clouds brewing over Persia and decided it was time to show some Shock and Awe. He may have bolted out of Antioch and with javelins and forks ready to strike. But unfortunately, we don't know. Our sources have dried up a bit... But at least we know how he died! (sort of).
