“After me, the deluge.” It was supposedly said by Tiberius referring to the probable reign of Caligula. It could have been said by GW Bush as well.
Interesting anecdotes. Edgar Rice Burroughs (author of Tarzan) wrote a historical novel about a Gallic slave who served the emperor’s household, and through that character expressed the view that Tiberius was the among the best and Caligula among the worst. Probably not far off.
