This page is still under development. Your patience is appreciated.



The Ius Antiquum denotes that period of Church history beginning with the time of Christ and running up to the publication of Gratian's Concordantia, that is, something over 1000 years.

Ius Antiquum, Sources


In many ways, the primary source for Ius Antiquum materials is Gratian's Concordantia, a work precsiely intended, of course, to bring together the legislation of the first millennium of Church history. But Gratian's work itself relied on still earlier attempts to collate ecclesiastical legislation, and these materials are important sources for Ius Antiquum studies today. They include:


A. Friedberg, ed., Quinque compilationes antiquae: nec non collectio canonum lipsiensis, (Tauchnitz, 1882). See also R. Naz, "Compilationes (Quinque-Antiquae)", DDC III: 1239-1241, and C. Duggan, "Quinque Compilationes Antiquae", NCE2 XI: 869.
