Fascinating blog post about this Worcester Cathedral manuscript, which is a collection of miscellaneous texts written in the tenth century and in its original binding (original medieval bindings are rare; tenth-century bindings are almost unheard of in my experience). I think this is Worcester, Cathedral Library, Q.5 [=W] (also described in the PDF catalog here).
While Anglo Saxon Bede is perhaps best known for his Ecclesiastical History, he was in fact a scholar in many other areas, too. De Arte Metrica focuses on grammar and meter and was originally written by Bede in the 8th century, though the Cathedral’s copy was written out in the 10th. As a piece of bibliographical history, the Cathedral’s copy is quite special. Bound with several other manuscripts about grammar, including Bede’s De Schematibus et Tropis and several unattributed samples of verse and other guides to meter, its binding also dates from the 10th century. There is evidence of later repair, and it seems likely this is due to some severe water damage sustained by the volume – the parchment in the latter half is heavily stained and has been repaired by a skilled conservator. It is unusual for a manuscript of this age still to be in an original binding, though, revealing the good care of the Cathedral monks and librarians throughout the centuries. The volume is believed to have been in the Cathedral Library since the 13th century at the very latest (though it is likely to have been earlier), and bears the rather handsome 1530 Worcester ownership plate on the front cover. While it’s easy to think of this as a work by Bede, it is notable that the spine makes no reference to him and is simply labelled Grammatica. It is common for bound manuscripts to have a general title, or occasionally no title at all, on the spine. Binding would have been expensive, and it was important to be cost effective by including several pieces in one volume.
