A technical drawing of a piece of chain-mail armor, showing a grid of interlocking oval links. The links are arranged in a regular pattern, with each link overlapping the next in both horizontal and vertical directions, creating a mesh-like structure.
Piece of Chain-armour.

Chain-mail, or CHAIN-ARMOUR, much used in Europe in the 12th and 13th centuries, and still used in India and the interior of the Asiatic continent, consists of hammered iron links, connected together by riveted links so that each link embraces four others, and worked into the form of a garment. Such armour was much more flexible and convenient to the wearer than that which was formed of steel or brass plates, but was less fitted to bear the thrust of a lance. See ARMOUR.
