Cassius Dio (c. 163-235)
“It seems that those who exercise supreme powers know more about everyhting else than they do about their own affairs, and although their associates have the fullest knowledge of their superiors’ actions, the latter possess no accurate information in return.”
- From Cassius Dio’s The Roman History (Book 55, chapter 10), translated by Ian Scott-Kilvert (Penguin Classics, 1987).
