Born at Pavia, Papiensis studied law and theology at Bologna under Gandulphus and Faventinus.

The work was compiled between 1187 and 1191, and was edited by Friedberg (Quinque compilationes antiquæ, 1882).
[3] Papiensis is the author of a "Summa" on his own compilation, which he wrote while Bishop of Faenza; it was edited by Laspeyres, as were also other works of the same author: Summa de matrimonio, Summa de electione, Casus decretalium, and a gloss on his Breviarium extravagantium (Bernardi Papiensis Summa decretalium, 1861).
He is also the author of a Vita sancti Lanfranci (Acta SS., IV Jun., 620 sqq.
