Les photos que j'ais son tirées d'un bouquin (Crusader art in the Holy Land, Vol1, 1099-1187). C'est apparement le dos du manuscrit appelé Psautier de Melisende (British Libray Egerton 1139).
sur wiki :"The spine of the psalter is decorated with Byzantine silk and silver thread, as well as red, blue, and green Greek crosses (which are also found in the royal arms of the kingdom). The spine was stitched by an artist who was most likely a westerner trained in a Byzantine style, as his stitching is not as smooth as other examples of Byzantine silk spines made by native Greeks."
