Lamellar Armor
Armor of small plates laced together with cord
Lamellar armor is armor made of small plates, usually rectangular and called lamellae, pierced with holes and laced directly to one another with cords or leather thongs. Unlike scale armor, which fixes its scales to a backing of cloth or leather, lamellar has no backing at all: the plates themselves are laced together in rows, both vertically and horizontally, to form the structure. The hard plates overlap densely to stop cuts and arrows, while the laced joints flex and follow the movements of the body. Originating in East and Central Asia, it spread across Eurasia, and the Japanese o-yoroi, the lamellar of Goguryeo Korea, the Byzantine klibanion, and the armor of Mongol horsemen are all built this way. The lamellae could be iron, bronze, hardened (lacquered) leather, horn, or bone, and at roughly 15 to 20 kg the armor rivalled plate in weight. A damaged plate could simply be re-laced and replaced, which made repair easy, but the lacing itself demanded constant care.
