Apocrisiarius

An apocrisiarius, the Latinized form of apokrisiarios (Greek: ἀποκρισιάριος), sometimes Anglicized as apocrisiary, was a high diplomatic representative during Late Antiquity and the early Middle Ages. The corresponding (purist) Latin term was responsalis ("he who answers").^[1] The title was used by Byzantine ambassadors, as well as by the representatives of bishops to the secular authorities.^[2] The closest modern equivalent is a papal nuncio; the title apocrisiarius is also still employed by the Anglican Church.
