heraldry, is when the shield, or a border, &c. is chequered, or divided into chequers or squares, in the manner of a chess-board.

This is one of the most noble and most ancient figures used in armoury; and a certain author faith, that it ought to be given to none but great warriors, in token of their bravery; for the chess-board represents a field of battle; and the pawns placed on both sides represent the foldiers of the two armies, which move, attack, advance, or retire, according to the will of the gamesters, who are the generals.

This figure is always composed of metal and colour. But some authors would have it reckoned among the several sorts of furs.
