"The violent death of Caligula [the previous emperor] afforded the Romans a fresh opportunity to have asserted the liberty of their country; but the conspirators had concerted no plan, by which they should proceed upon the assassination of that tyrant; and the indecision of the senate, in a debate of two days, on so sudden an emergency, gave time to the caprice of the soldiers to interpose in the settlement of the government.
By an accident the most fortuitous, a man devoid of all pretensions to personal merit, so weak in understanding as to be the common sport of the emperor’s household, and an object of contempt even to his own kindred; this man, in the hour of military insolence, was nominated by the soldiers as successor to the Roman throne."
