The Byzantine plow was, technically, not a plow at all, but a sole ard.
Boy, there’s a term you don’t see every day. “Sole ard.” Kinda makes your knees weak, doesn’t it?
FYI, apparently a sole ard scratches the surface rather than turning it over like the plows we see today. The tool is suitable for shallow tilling, as in arid areas, and requires less effort to use than moldboard plows (less force is needed than to overturn the soil).
