SUMMARY: Book inventories of two Bologna teachers are here published and discussed. Thomas of Arezzo, physician and professor at the University, was implicated in an action in 1286; a double list of his books, 34 titles in all, is preserved among the records of his trial. Philip Christianus, teacher of grammar, sold his books in 1341: the bill of sale lists 41 titles. Most of them are texts of logic, philosophy, medicine, which Dante could have the opportunity to read, when he was in Bologna (ca. 1292-1294) in order to study philosophy. In Thomas of Arezzo’s inventory some works are remarkable: these are the texts by Boetius of Dacia and Siger of Brabant, which appear to be read in Bologna in spite of the recent condemnation by the bishop of Paris.
