Byzantine style binding. Wooden boards cut flush with the textblock; grain parallel to the spine; thickness 12 mm; sharp grooves in board edges all around. Unsupported sewing at 5 stations prepared with v-nick at distances measuring 40, 98, 156, 211, 252 mm from head edge. Sewing thread of medium thickness, s-ply. Board attachment: only a tiny portion of the thread visible on the inner face, the zigzag-pattern probably on outer face of the boards. Rounded spine. Plain cloth spine lining. Covered in full fine-grain black goat leather.
Raised endbands extending onto board edges, angled attachment (thread not visible on inside of board). The thread used for attachment at head and tail is thinner and paler than the one used for sewing of the textblock. Primary endbands with double support, plain thread.
Remains of one of the triple interlaced strap fastenings still there on inside of right board, made out of the same black leather as covering; of the two metal foredge pins on the opposite board one is intact, the other broken. At headband two loops for markers, in red and green silk respectively. Vestiges of what seems to have been a board strap marker can be seen on ff. 54v–55r, where interlaced leather straps have left an imprint in brown on the pages.
Blind tooling on board covers with a four-line tool and small hand tools (tiny quatre-feuil in circle, six-pointed star or flower in circle, fleur-de-lis in lozenge, bird in lozenge). Small flat metal bosses in corners and center of boards, some of them missing.
