The new profession of the delator must have given a stimulus to oratory.
A delator of infamous character, one Peter, had accused the authorities of the city to the tsar of conspiracy; Ivan, without even confronting the Novgorodians with their accuser, proceeded at the end of 1569 to punish them.
Although the word delator itself, for "common informer," is confined to imperial times, the right of public accusation had long been in existence.
If the delator lost his case or refused to carry it through, he was liable to the same penalties as the accused; he was exposed to the risk of vengeance at the hands of the proscribed in the event of their return, or of their relatives; while emperors like Tiberius would have no scruples about banishing or putting out of the way those of his creatures for whom he had no further use, and who might have proved dangerous to himself.
