Abstract

Jurist and ecclesiastic, author of an important corpus of political and legal texts, active in the service of the church, as a university professor and diocesan administrator, Bernard de Rosier (1400–75) is remembered by diplomatic historiography as the author of theAmbaxiatorum brevilogus(1435–36), generally considered to be “the first textbook of diplomatic practice written in Western Europe” (G. Mattingly). Rosier also wrote an account of Pierre de Foix's 1427–30 legation to Aragon, on which he served as secretary, and a treatise on the office of papal legate.
