Lorica segmentata is a type of armor used by the ancient Roman military, particularly during the late Republic and early Empire periods. It consists of overlapping metal plates, which are fastened together to provide flexibility and protection. This design allowed soldiers, known as legionaries, to move more freely while still being well-protected in battle. The armor typically covered the torso and was complemented by other pieces, such as a helmet and greaves. Lorica segmentata was favored for its durability and effectiveness, making it a symbol of Roman military strength. Its construction often included iron or bronze, showcasing the advanced metallurgy of the time.
