10th-14th century. 3 3/8” length of heavy pyramidal form with square eye. Rarely found in this large size. Originally mounted on a slender handle which allowed for maneuverability while being repeatedly hit by the hammer, much like primitive tattooing. Used to create the fine stone work of the great cathedral and palaces, much of which was done a hundred feet or more above the ground. If dropped, they perished in the mud below until being found as was this one.
