BOMBOLOGNO (from BOLOGNA). — Dominican philosopher and theologian, born in Bologna at the beginning of the 13th century, died there in 1280 A.D. He entered the religious life and completed his studies in Bologna. He probably lectured on the *Sentences* in Paris (1266–68), and for several years taught in Bologna, where he was also regent of the Studium from 1277 to 1279.
The fruit of his teaching included a commentary on the *Sentences* and various works on logic: such as commentaries on Porphyry, Aristotle’s *Categories*, the *Peri Hermeneias*, and Gilbert of Poitiers’ *Liber sex principiorum*. The only work that has come down to us is the *Commentary on the Sentences* (though Book II is missing). It is preserved in Bologna (Books I and III, University Library, cod. 1506, 1508; Book IV, Archiginnasio Library, cod. B 1420) and in Assisi (only Book III, Communal Library, cod. 155). Bombologno’s method is that employed by other authors of similar works. His principal sources are St Thomas Aquinas, Peter of Tarentaise, St Bonaventure, and Annibaldo degli Annibaldi. He displays a wide familiarity with the works of Aristotle and Arabic philosophy, which he seems to know far better than his sources do.
