Peter Collivacinus

Peter Collivacinus (also called Morra), an ecclesiastical character of the 13th century, flourished as teacher of canonical law at Bologna; was then secretary to Innocent III, by whose order he collected the decretals of that pope during the first eleven years of his reign, and published them in 1210 by the help of the so-called Compilatio Romana of Bernhard of Compostella. This collection was approved by the University of Bologna, and received the name Compilatio tertia. (The socalled Compilatio secunda is younger, but contains older material. See Richter, Kirchenrecht, § 74.) Later, Peter was cardinal legate, and as such labored to restore order to the Church of South France, in his day so greatly broken up by the wars of the Albigenses (q.v.).
