Byzantine style binding. Wooden boards cut flush with the bookblock; grain parallel to the spine; thickness 9 mm; shallow grooves in board edges all around. Unsupported sewing at 4 stations prepared with v-nick at distances measured from head edge: 30, 95, 150, 200 mm. Coarse sewing thread with a z-ply. Attachment with Z-pattern on inside of board. Flat spine, with a tendency for concaveness in the latter half of the bookblock. Spine lining of coarse plain cloth all along. Covered in full reddish-brown goat leather with a polished surface.
Raised endbands extending onto board edges, attachment thread passes straight through the board. Same thick thread used at head as for the sewing of textblock; a finer one at tail (later repair?). A modern spine label in paper, text not readable. Compound endbands with secondary weaving in yellow, red, green and blueish-black silk at the head, in red and green at tail.
One foredge pin, but no straps or even holes visible on opposite board (indicating refurbishing?) No tooling. No bosses, although there are two holes in the center of left board, where discoloration on inside may suggest previous nailing of some furniture, perhaps a cross considering the scratching marks in the leather.
