The cross moline is a design element used as a mark of cadency in heraldry, particularly English heraldry. It is so called because its shape resembles a millrind (fer de moline in Old French), the iron clamp of the upper millstone. It is borne both inverted and rebated, and sometimes saltirewise or in saltire. When used as a mark of cadency it represents the eighth son.
