Quinque compilationes antiquae

The Quinque compilationes antiquae[a] is a set of five collections of twelfth and thirteenth century decretals (specifically extravagantes)[3] totalling between 1,971[4] and 2,139 chapters.

[13] It contains only decretals by Pope Innocent III, who expressed his approval of it and vouched for the authenticity of its contents, even though not all of them can be found in the papal registers.

[6] Unlike the first four compilations, the Compilatio quinta contains secular legislation, specifically portions of Hac edictali lege, a statute written by Emperor Frederick II.

[19] Frequently cited by contemporary canonists,[13] the Quinque compilationes antiquae served as the "standard textbook" for the study of decretal law in the early thirteenth century.

[21] Some 1,756 chapters' worth of content in the five collections were subsequently incorporated into the Liber extra decretalium by Raymond of Penyafort, which was commissioned by Pope Gregory IX in 1230 and completed in 1234.
