[German version]

Someone who has something to announce or proclaim. In a narrower sense the term is applied to those who, whether as a private individual or on behalf of an office, report a criminal offence. Denuntiator is then very often synonymous with  delator . The excesses of the latter had a lasting effect on the public opinion on denunciation. Denuntiatores crop up in Rome even as junior officials in the role of heralds. For similar functions in Greek law  menysis ,  sykophantes .
