“Innocent V.” Petrus a Tarentasia, born in Tarentaise, towards 1225, elected at Arezzo, 21 January, 1276; died at Rome, 22 June, 1276. At the age of sixteen he joined the Dominican Order, and he won great distinction as a Professor at the University of Paris, whence he is known as Doctor Famosissimus. He is the author of several works dealing with philosophy, theology, and Canon law, some of which are still unpublished. The principal of these is the “Commentary on the Sentences of Peter Lombard.” I have used the edition, Toulouse, 1652.
