This codex contains a rare illuminated manuscript constituted
entirely by illuminated pages, for each of which only a succinct
caption is given, most often only a line of text, and which
therefore provides exceptional historical image-sources for
numerous domains. The pictures presented here of military
technology were perhaps originally part of a medieval house book. A
typical collector’s item, this illuminated manuscript underscores
the collection character of the Rheinau conventual library, whose
librarians and abbots were expressly on the lookout for rare books.
