Abstract

This research note identifies for the first time the principium on book I of the Sentences by the prolific polymath Henry of Langenstein. This discovery, when combined with the four principia of the Augustinian Denis of Modena, provides the evidence necessary to demonstrate that Langenstein lectured on the Sentences at Paris in 1371-1372. The note also establishes the identity of the other eight bachelors of theology who participated in the principial debates that year.
