FIRST AND ONLY EDITION of this rare commentary on Petrus Lombardus's Sentences. Once attributed to Thomas Aquinas, it is now believed that this work was written by one of his students, Hannibaldus de Hannibaldis (d. 1272), who entered the Dominican Order at Santa Sabina in his home city of Rome. He subsequently went to Paris where he became a student of Aquinas. Hannibaldus' commentary departs from early Thomistic positions, and also contains excerpts from Saint Bonaventure and Pope Innocent V. BMC III:770; Goff T-329; iSTC it00329000. VERY RARE: We trace only two copies of this work at auction in the last 45 years.
