Chainmail is a material used to make armour, and consists of small rings of metal put together to form a mesh. Chainmail has been used at least since the time of the Roman Empire, and was an important armour material up until fully articulated plate armour became available. Several ways of linking the rings together have been known since ancient times, the most common being the 1-to-4 pattern where each ring is linked with four others.

The word chainmail is actually an anachronism. In the Middle Ages and Renaissance, it was simply called "mail", "maile" or "maille"; derived, through the Italian "maglia", from Latin "macula" - meaning "net".

Manufacture

In Europe, the 1-to-4 pattern was almost completely dominant, with 1-to-6 being seen very rarely. In East Asia (primarily Japan), chainmail was also common, but here several more patterns were utilized and an entire nomenclature developed around them. In the Middle East, yet other patterns were developed and often combined with metal plates linked in with the rings.

Historically, the rings composing a chainmail armour would be riveted or welded shut, to reduce the chance of the rings splitting open when subjected to a thrusting attack or a hit by an arrow.

In modern reenactment and live-action roleplaying (LRP), suits of chain mail are hand-made from rings of wire. They may or may not be welded or soldered but are rarely riveted. They may alsobe made of split sprung steel washers. Usually two pairs of pliers are used to bend the washers open and closed whilst "knitting" the chainmail. The resulting mail is usually heavier than traditional wire-wound mail.

Trivia

In tests during the World War I, chainmail was tested as a material for bullet proof vests, but results were unsatisfactory, as the rings would fragment and further aggravate the damage. A mail fringe, designed by Captain Cruise of the British Infantry, was also added to helmets to protect the face but this proved unpopular with soldiers, in spite of being tested proof against a three-ounce shrapnel round fired at a distance of one hundred yards (92.3m).

In many films, chainmail is sometimes substituted for by knitted cloth spray painted with a metallic paint. There are also machines which knit metal wires to produce something which looks somewhat like mail, usually for use on things like butchers' gloves.
