Medieval Manuscript Leaves: Home

This guide provides information about the eight Medieval Manuscript Leaves held by NIU Libraries Rare Book Room.


Books during the medieval period were typically made of vellum (also called parchment), or, occasionally, especially during the later medieval period, paper. The cost of a book was dependent upon its size (both in height and in number of pages), and how much decoration it had (the more illustrations and illuminations, the more expensive the book). "The production of books was a collaborative enterprise involving co-operation between different crafts: parchment-maker, scribe, illuminator, and binder, together with, in many cases, a bookdealer who took orders from clients and oversaw the making of the final article" (1).

Before 1200, books were generally produced in monasteries. However, as universities in cities like Paris, Bologna and Oxford began to grow, the demand for books outgrew the abilities of the monasteries to produce them, and lay people stepped in to fill the gap. By 1400, most manuscripts were not produced in monastery scriptoria, but by professional book workers.

Please Note

  • Click on the tabs to view digital images and information for each of the leaves. 
  • The sizes of these images were adjusted to fit the computer screen and are not to scale. Click on the thumbnail versions to see a larger picture. 
  • All of the images are of single leaves --2 pages from a book, with a front (recto) and a back (verso). Originally, these leaves were all part of complete books.


The illuminated manuscripts included here were purchased through the kind auspices of the Friends of the Northern Illinois University Libraries.  Professor Ann van Dijk, the Art History Division of the School of Art and Design,  assisted the RBSC, selecting the leaves in our collection. Many of the leaves were digitized by Charles Larry, former Head, Social Sciences and Humanities, University Libraries. The original research on the leaves was performed by Jessica Witte and Kay Shelton.
