With respect to their contents, the collections to be analyzed in this part can be separated into two or three major types. First are what I will call “unified” collections. These contain sermons that are attributed to a single named author or collector, or else are unified by a specific milieu in which they were preached (e.g., Cambridge University), or by peculiar structural or stylistic features (e.g., macaronic sermons of a distinct style). Such collections usually do not share their material widely with others. In contrast, “miscellaneous” collections do precisely that: they share individual sermons among themselves and thus may be assumed to have drawn their material from several different sources. This material could have been gathered by one or by more collectors, and the texts may be written in one or in several hands. Occasionally, both unified and miscellaneous types occur in the same manuscript and were written by the same scribe. This combination I will call a “mixed” collection, of which Cambridge, University Library, MS Kk.4.24 (B) is a good example: here a unified collection of sermons in regular liturgical order, ascribed to Bromyard, is followed by a random series of sermons, some of which also occur elsewhere, the whole codex being written by the same hand. It should thus be clear that “collection” and “manuscript” are not synonymous.
