 of Dionysio-Hadriana


Charlemagne asked Pope Hadrian I for a book of canon law in 774.  Hadrian sent him an expanded copy of the Dionysiana, which is called Collectio Dionysio-Hadriana.  A collection of conciliar canons and papal decretals.

The most influential collection of the Carolingian period was the Dacheriana (ca. 800 A.D.)  56 manuscripts of the collection are extant.  Probably compiled in Southern France, possibly Lyon, perhaps by Agobard of Lyon.  It was a systematic collection.  Lotte Kry,  Canonical Collections of the Early Middle Ages (ca. 400-1140): A Bibliographical Guide to the Manuscripts and Literature.
