linked together, alternating closed washer-like rings with riveted rings. This produced a very flexible, reliable and strong armour. Each ring had an inside diameter of between 5 and 7 mm, and an outside diameter of 7 to 9 mm. The shoulders of the lorica hamata had flaps that were similar to those of the Greek linothorax; they ran from about mid-back to the front of the torso, and were connected by brass or iron hooks which connected to studs riveted through the ends of the flaps. Several thousand rings would have gone into one lorica hamata. Although labour-intensive to manufacture, it is thought that, with good maintenance, they could be continually used for several decades. Its utility was such that the later appearance of the famous lorica segmentata—which afforded greater protection for a third of the weight—never led to the disappearance of the ubiquitous mail, and, in fact, the army of the late empire reverted to the lorica hamata once the segmentata had fallen out of fashion. Lorica squamata Lorica squamata was a type of scale armour used during the Roman Republic and at later periods. It was made from small metal scales sewn to a fabric backing. It is typically seen on depictions of standard bearers, musicians, centurions, cavalry troops, and even auxiliary infantry, but could be worn by regular legionaries as well. A shirt of scale armour was shaped in the same way as a lorica hamata, mid-thigh length with the shoulder doublings or cape. The individual scales (squamae) were either iron or bronze, or even alternating metals on the same shirt. They could be tinned as well, one surviving fragment showing bronze scales that were alternately tinned and plain. The metal was generally not very thick, 0.5 mm to 0.8 mm (0.02 to 0.032 in) perhaps being a common range. Since the scales overlapped in every direction, however, the multiple layers gave good protection. The size ranged from as small as 6 mm (0.25 in) wide by 1.2 cm tall up to about 5 cm (2 in) wide by 8 cm (3 in) tall, with the most common sizes being roughly 1.25 by 2.5 cm (0.5 by 1 in). Many had rounded bottoms, while others were pointed or had flat bottoms with the corners clipped off at an angle. The scales could be flat, slightly domed, or have a raised midrib or edge.
