The lorica segmentata was an armour type primarily used in the Roman Empire, and the name is thus derived from Latin. The armour itself consist of broad metal strips bound together by leather straps. The metal strips were placed horizontally overlapping and circled the body, usually being tied together in the front. The construction of the armour allows it to be stored very compactly, as it is possible to fold in on itself. During the time of its use, it was modified several times.
A problem with the lorica segmentata was that the weight in large parts rested on the shoulders, meaning that long training was needed in order to use it for extended periods of time.
During most of the period of its use, only legionaries (heavy infantry of the Roman Legions) would be issued with the lorica segmentata. Auxiliary forces would more commonly use chainmail or other forms of light armour.
For some not entirely understood reason, it fell out of use after the decline of the Roman Empire, only to reappear in a more advanced form during the 1500s, using sliding rivets and under the name of Anima.
