The earliest method of sewing the codex book, sometimes called coptic binding, in reference to its origin in North Africa, was an "unsupported" technique of chain stitching. The sewing thread simply links to the previously sewn section of the textblock, forming a chainlike pattern of stitches across the spine, rather than being sewn onto cords connecting the covers across the spine, as with European books. This sewing method was used for centuries in cultures around the eastern Mediterranean, the Islamic Near East, and in North Africa.

Greek, fourteenth century
Greek manuscripts from the medieval period were often sewn with heavy thread recessed into slits across the textblock spine. Because this heavy thread caused the spine to swell, once the boards were attached the spine often had a rounded shape.

Islamic manuscripts over many centuries have been sewn with a simple chain-stitch method, often with very thin thread. As this Ottoman binding shows, the resulting shape is a book with a flat and smooth spine.
