Scale armour is an early form of armour consisting of many individual small armour scales (plates) of various shapes attached to each other and to a backing of cloth or leather in overlapping rows. Scale armour was worn by warriors of many different cultures as well as their horses. The material used to make the scales varied and included bronze, iron, rawhide, leather, cuir bouilli, seeds, horn, or pangolin scales. The variations are primarily the result of material availability.
Scale armour is armour in which the individual scales are sewn or laced to a backing by one or more edges and arranged in overlapping rows resembling the scales of a fish/reptile or roofing tiles. The scales are usually assembled and strapped by lacing or rivets. Lorica squamata is an ancient Roman armour of this type.
Other types of armour made from individual scales but constructed in a different manner have their own separate names, such as lamellar armour where the individual scales are perforated on several or all edges and lashed tightly to each other in straight ridged rows and do not need to be attached to a backing. The Romans also had a variant called lorica plumata in which the scales were attached to mail.
The Scythians' horse warriors appear to have used scale or possibly lamellar armour, evident both from contemporary illustrations and burial finds in kurgans. The armour was made from small plates of iron or bronze. Unique to the Scythians, about 20% of the females found in graves were dressed for war, some including armour, which may have inspired the Greek tales of Amazons.
Due to the semi-rigid nature of the armour, the Scythian variety was made as breast- and back-plates, with separate shoulder pieces. Some finds indicate partial armour, where a leather shirt or similar garment have sewn-on scales in places, particularly around the neck and upper chest.
