Lorica segmentata (lat. Lorica segmentata, lorica out of segments) – is an armor made out of metal segments, protecting torso and part of the shoulders. Roman army used the armor approximately from the Augustan period into the third century CE.
The main lorica segmentata’s difference from other roman armours is its design – iron strip segments (which can be considered from the name), which are by pairs connected with leather straps on the chest and on the back. The construction wraps around legionary’s torso protecting it. Shoulders and upper back had additional armor plates. Those segments were interconnected by hooks or by straps or buckles.
Lorica segmentata is a modern conventional name. Its exact ancient name is unknown; assigning the term’s origin exclusively to the Victorian period is incorrect.
The separable construction allowed maintenance of individual components. The Corbridge Hoard, discovered in 1964, contained pieces of several armours and other military equipment in a wooden chest. It provided crucial evidence for reconstructing the armour. Why the chest was stored or abandoned is unknown: the find does not itself establish a hurried garrison retreat.
Weight and protection depended on plate thickness, size and construction. Articulated armour covered the torso and shoulders, but did not make its wearer invulnerable to every weapon.
Tests of modern replicas help compare constructions. Results depend on materials, padding and experimental conditions; one test cannot guarantee an ancient soldier’s protection against a sword, arrow or scorpio bolt. The lower body remained less protected. The military belt’s hanging straps were not equivalent to a metal cuirass.
Composite metal armour existed before Roman lorica segmentata. The Dendra panoply belongs to the Mycenaean period and combines large plates. Similarities between individual components do not demonstrate direct ancestry for the Roman construction.
Tacitus describes the Gallic crupellarii as heavily protected with iron. His account does not establish that they wore lorica segmentata of a known archaeological type.
More than that, there is a depiction of Sarmatians wearing segmented armor on Trajans’Column. This shows us, that other tribes also have similar armor, but built differently.
There is a theory, that Romans were inspired to create segmented armor by Hellenic armor type, depiction of which we can see in Domus Aurea.
Historians associate the appearance of lorica segmentata in roman army with Germanic Wars (year 12 BCE – year 12 CE) during Octavian Augustus reign, when there was a need to protect better legionary’s torso in battles with Germanic tribes. The earliest lorica segmentata’s fragments were found, where Battle of the Teutoburg Forest happened (year 9 CE) and the lorica segmentata is attributed to kalkriese type.
Throughout roman history, lorica segmentata experienced multiple modifications. Leather attachments – buckles and leather straps, were substituted for metal pins and pivots, which made armour sturdier and at the same time did maintenance and production a lot easier. The most common lorica segmentata types can be distinguished according to the findspot in following way:
• Kalkriese
• Corbridge
• Newstead
The Kalkriese type is an early form of Roman articulated armour. Initially its construction was studied through individual plates and fittings.
A much more complete armour was discovered at Kalkriese in 2018 and presented in 2020. The find preserved important fittings and organic remains. Its shoulder construction differs from later variants, but the claim that it lacked shoulder protection altogether is incorrect.
The Corbridge Hoard, found in 1964, contained fragments of several armours rather than two complete cuirasses. Comparison of the components allowed reconstruction of variants designated A and B. Type A included connections using straps and buckles. The hoard’s deposition date and the type’s period of use are different questions: the chest is conventionally dated to deposition between AD 122 and 138.
There is another found lorica segmentata type. Corbridge B features hooks chest attachment. The rest is quite similar to type A.
Newstead is the latest lorica segmentata type (year 110 CE – year 250 CE). Compared to Corbridge, the construction is significantly eased, which is most likely connected with production process optimization. Brass decorations are minimized, and chest pieces are interconnected by common bolts. The lorica segmentata was found in Newstead, in the beginning of XX century.
Articulated armour is often associated with legionaries, especially through Roman monumental imagery. Finds at auxiliary forts, however, prevent treating it as exclusive to the legions. An image’s absence from reliefs does not prove that every centurion or other category of soldier was prohibited from wearing it. Mail and scale armour coexisted with it.
Articulated armour ceases to be prominent in late Roman archaeological material. A single army-wide withdrawal date cannot be established. Vegetius’s complaint about infantry abandoning protection is not a specific decree abolishing lorica segmentata under Gratian. Changes in armour cannot be explained solely by general “decline” or “barbarisation”.
The main reenactment period of our club is middle of the I century CE – beginning of the second century (year 50 CE – year 125 CE). So, according to that, lorica segmentata which fits best for an early legionary is Corbridge, and lorica segmentata which fits best for later periods (the beginning of the second century) - Newstead. To make lorica segmentata you need – iron, brass (bronze), leather, rivets.
