4.B.12. RITHMOMACHIA = THE PHILOSOPHERS' GAME
I have generally not tried to include board games in any comprehensive manner, but I have recently seen some general material on this which will be useful to anyone interested in the game. The game is one of the older and more mathematical of board games, dating from c1000, but generally abandoned about the end of the 16C along with the Neo-Pythagorean number theory of Boethius on which the game was based.
