Rainerius Pomposanus

late 12th/early 13th c.


Alternative Names

Rainierius de Pomposa; Reinerus Pomposanus; Rainier of Pomposa; Rainer of Pomposa; Rénier de Pompose; Rainer von Pomposa; Rainero da Pomposa



Deacon and monk of the abbey of Pomposa. Rainier compiled his collection of decretals in 1201. It contains 123 chapters taken from letters issued during the first three years of Innocent III’s pontificate (1198–1201). Rainier drew directly from the papal registers and arranged his material in 41 titles. They differ considerably from those given in the most important compilation of his days, Compilatio prima. His work was later used by other decretal compilers, such as Gilbertus (1202) and Alanus (1206).
