[ provides an edition of the text, but mistakenly attributes it to Cardinal Giacomo Tomasi Caetani. See .] written in 1219, is the original
formulary of the apostolic penitentiary. It is a valuable record of papal penances imposed, dispensations granted and sentences handed down. His ''Ars dictandi'', begun before 1216 and finished after 1220, describes the proper form and style of the papal chancery. Among his sources were the ''Rationes dictandi'' of
Hugh of Bologna and the ''Summa dictaminis'' of
Guido Faba.
About 700 letters written by Thomas are preserved. They are remarkable for their elevated
Latinity and their value as a historical source for the
conflict between church and empire in Italy. They are mostly official letters and mandates, but there is some private correspondence. His ''Ars dictandi'' and 623 of his letters were gathered together into a single collection, the ''Summa dictaminis Thome Capuani'', which survives in 65 manuscripts.
