Delatores (political informants) and accusatores (malicious prosecutors) were a major part of life in imperial Rome. Contemporary sources depict them as cruel and heartless mercenaries, who bore the main responsibility for institutionalizing and enforcing the tyranny of the infamous rulers of the early empire, such as Nero, Caligula, and Domitian. Steven Rutledge's study examines the evidence and asks if this is a fair portrayal.
