Abstract
This article describes a large (713 page) manuscript: Cambridge, Gonville and Caius College, ms. 290/682, which is a paginated copy of Peter Lombard’s Sentences. Approximately 175 of its pages contain various fourteenth century scholastic texts, which are frequently written around the margins of the Sentences text. A few of these fourteenth century scholastic texts have been integrated into critical editions that have described the manuscript using M. R. James’ early 20th century catalogue, but the manuscript’s scholastic contents have never been systematically described. Close examination discloses several hitherto-unnoticed scholastic texts: fragmentary witnesses of Gregory of Rimini’s In Sent. II, excerpts from Ockham’s quodlibeta, most of Peter Auriol’s In Sent. II, d. 1-7, Robert Holcot’s determinatio n. 15/In Sent. III, q. 2, and a new text on identity and mereology, whose authorship I tentatively assign to Robert Holcot. In addition, there are numerous other scholastic texts of considerable intellectual interest for fourteenth-century philosophical theology for which I have not been able to establish an identification.
