Explanation: Emperor Diocletian of the Late Roman Empire is a contentious figure. Many, like myself, deride his 'reforms' as autocratic, oppressive, ruinous, and against the traditions of Rome. Others claim that his reforms were necessary and extended the life of the ailing Roman Empire.

He, uniquely for a Roman Emperor, did not die in office, but instead retired peacefully, of his own volition no less, to go farm cabbages.

If only he would have found his calling a little sooner in life.
