Being an emperor in ancient Rome was a dangerous business.
 
Most of the nearly 100 emperors from the dawn of the Roman empire to its fall died violently—often the victims of assassination, battle wounds or gruesome maladies.
 
A sly work of cartoon history, with a touch of dark wit, Et Tu, Brute? is an irreverent, illustrated compendium of the deaths of all the Roman emperors.

Here Nero stabs himself in the throat, Tiberius is smothered in his sleep, Caligula is stabbed by his own praetorian guard and Claudius is fed poisonous mushrooms by his wife.
