In the heart of the medieval book, where the quires are united and meet the binding, great secrets loom in the dark. This is the place where we can read things in the manuscript that cannot be read on its pages: whether it is composite and in what manner it is composite. The question of whether a collection of texts was copied continuously or whether it was formed by binding together independently produced units, is of the utmost importance for understanding the object’s genesis and for “getting” the texts as a collection. Providing an answer to this query is difficult, however, because it depends on facts buried deep inside the quire construction of the book – which may, moreover, not be obtained without upsetting librarians. Nevertheless, one must persevere, treading as carefully as possible, because exploring the dark side of the manuscript pays off.

The first thing to do is assessing whether a manuscript is composite or not. Determining that an object is not composite is easy enough. A collection of texts copied continuously is usually written by the same scribe. Mind you, in such case the book may still be composite, for the scribe may have united individual units he copied in the past. However, if the writing style (duct) and ink color are the same throughout, and especially if all catchwords are in place and in the same style, the text collection was likely copied in one “go”. There is one trap, hidden in plain sight: a book produced by multiple scribes may still be copied continuously. Sometimes a scribe stopped working on a project and another took over. The individuals usually tried to hide such transitions by “breaking” at the very end of a page: the first stopped after completing the last line on the recto side of the leaf, the second started with the first line on verso. Less frequently, the switch may also occur in the middle of the page; or even in the middle of a line. This intriguing scenario can usually not be explained. Was the first scribe suddenly overcome with tiredness? Had the abbey beer of the previous night gotten to him? Did he have a blind date with the rubricator?

The domain of composite books is much darker – and more slippery. This is in large part due to the fact that such objects can be composite in different ways. They may consist, for example, of units that were designed and created specifically to be bound together, while in other cases such units were merely united because of their similar dimensions. In some composite books all individual units were in use by themselves before they were bound together, while in others only some of them were, or none at all. Consequently, any two individual units of a composite book (and the texts they hold!) may have very different relations to one another: either they are new neighbors or their kinship predates the volume. Descriptions in manuscript catalogues usually do not clarify such relations. The better ones will mention that a manuscript consists of multiple units, but that is often the end of it. Take the following examples, all taken from existing catalogues: “Latin works on science and mathematics assembled from several 13th-century booklets,” “A miscellany of five separate manuscripts,” “A set of five volumes” and “Three independent manuscripts bound together.” The volumes are composite, but how? How are we to understand “assembled” in the first description? And how meaningful is the use of different terms in these examples (“booklets”, “volumes” and “independent manuscripts”)?
Ultimately these descriptions show that bringing the genesis of a manuscript into play in your research normally requires you to go into the field and observe the object “in the flesh”. There is much to gain when you do. For example, the genesis of the book may tell us something about the availability of exemplars – and thus, perhaps, where we may situate the scribe. A scribe may have had all the exemplars he needed in front of him when he started to copy. Then again, he may not, for example because his hunt for exemplars had been only partly successful. Availability is a key consideration for the manuscript to become composite or not. After all, the scribe could wait until he had all the material he needed and copy everything at once. The result would be a full manuscript if he copied a lot of texts, or a booklet if the planned collection was modest in scope. If there was much to copy but there was a supply problem, he could decide to copy the collection in “installments”. The result would be a series of booklets, all in the same hand, bound together in a single volume. As he was waiting for new material to become available, the scribe could start using the booklets he had already copied, adding new installments as he got his hands on more exemplars. This is a different scenario again, one where some pages within a composite book (consisting of several parts copied by one hand) show wear and tear.

While the examples provided here may suggest that variation is endless, there are, in fact, only a limited number of ways to produce a composite book. Obviously, knowing the possible scenarios helps to deduce in what way a manuscript in front of you is composite. The first step, however, is to realize that the manuscript you are looking at, even when it is copied by one hand throughout, may be the product of extensive tweaking over a long period of time.
