 From the 12th century onward the formularies of the papal Curia become more numerous but less interesting, since it is no longer necessary to have recourse to them to supplement the documents.The formularies of the Cancellaria Apostolica are collections drawn up by its clerks, almost exclusively for their own guidance; they interest us only through their relation to the "Rules of the Chancery".The formularies of the Poenitentiaria have a higher interest for us; they appear during the 12th century when that department of Roman administration was not yet restricted to questions of conscience and the forum internum, but served as a sort of clearing-house for lesser favours granted by the Holy See, especially for dispensations.
