Apparently this was a byzantine tabletop game, and tied to chess:
Iirc typical chess also existed, and was termed Zatrikion (which afaik means 'absolute victory'). In the version in the pic the moves go in a circle and not in a line. It seems that the central circle is impassable terrain, and you can attack from two sides instead of the one in regular chess
