The history of Islamic bindings is hampered by the lack of evidence about the date and place of production of the bindings. The library of the Saadian sultans of Morocco provides at least some clues about the local production in the fifteenth and sixteenth centuries, before the introduction of the plate stamping that local binders borrowed from Ottoman sources. As the library was captured by Spain in 1612, many bindings are still in the condition they were in at that date. This article focuses on manuscripts transcribed in Morocco during the fifteenth and sixteenth centuries and intends to define a type of bindings that seems to have been very successful at that moment.
