The Deeds of Pope Innocent III, composed before 1210 by an anonymous member of the papal curia, provides a unique window into the activities, policies, and strategies of the papacy and the curia during one of the most important periods in the history of the medieval church. Innocent III, who became pope in 1198 and reigned until 1216, has long been regarded as one of the most important popes in history. Though the discussion of Roman politics found in these pages is one of the most valuable sources available to us, never before has the work been translated into any modern language. It is a treasure of contemporary letters, arranged by the author to reinforce his interpretation of the events discussed. The results are new insights that will inspire both students and scholars.
