This paper manuscript of the later fifteenth century contains a number of different materials, which are all theological in nature and potentially related to preaching. They have been collected in what is basically a notebook, whose quires vary in size and are marked consecutively by a medieval hand. Of interest here is the third main section of ten quires that range in length from eight to sixteen folios (ff. 209–323). This contains a random collection of sermons together with some theological extracts and quaestiones that are provided with subject headings (from f. 269 on; see below). It is the work of several fifteenth-century scribes. They tend to begin a sermon, and usually an extract, on a new page. Even where the material occupies only a few lines, the remainder of the folio is left blank. There are twenty-six sermons. The first eight, written by the same hand (ff. 209–224), are addressed to an academic audience and use such hyperbolic addresses as “Prehonorandi domini” or “Studiosissimi magistri.” The first, for 2 Advent, bears the rubric “Samelyn Oxon’”; others are said to have been preached in Latin at Oxford (3) or Cambridge (4, 6), and the last of this group presents itself as a sermo examinatorius (f. 222). They all have a strong theological flavor and draw heavily on the fathers in long quotations. The group of eight is further characterized by invoking the Blessed Trinity at the head of several pieces (2, 3, 7, 8).
