The book is very small: the size of each vellum folio or page is 3 5/8 x 2 7/16 in. (9.2 x 6.2 cm), and the overall size including the current replacement binding is 3 7/8 x 2 13/16 x 1 1/2 in. (9.9 x 7.2 x 3.8 cm). There are 209 folios, with 25 full page miniatures, but many other historiated initials and images in the borders of most pages, so that over 700 illustrations have been counted. Only ten folios have no decoration, just plain text, suggesting that the book was never entirely finished. The vellum is extremely thin, almost transparent, and the text by an unknown scribe is very finely written.
