Black Hours, Bruges, c. 1470
This Book of Hours, referred to as the Black Hours, is one of a small handful of manuscripts written and illuminated on vellum that is stained or painted black. 
The black of its vellum—the very thing that makes the codex so striking—is also the cause of some serious flaking. The carbon used in the black renders the surface of the vellum smooth and shiny—a handsome but less than ideal supporting surface for some of the pigments. 
The anonymous painter of the Black Hours is an artist whose style depended mainly upon that of Willem Vrelant, one of the dominant illuminators working in Bruges from the late 1450s until his death in 1481.

Above: a medieval manuscript mended with embroidery. Photos via the Uppsala University Library. Here is some information about the manuscript from their page:

The pages of the book are made of parchment and they show typical damage in the form of holes and tears that happened while the parchment was being made. Some time after the book was copied, the holes and tears have been mended artistically with silk of various colours, mainly in blanket stitch as used in embroidery. 

The old mending is in good shape except for those parts which were sewn with black silk. The thread is so fragile that it disintegrates on touch.
