Mirror armour

Mirror armour is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mirror armour rather than just read about it. In short: Mirror armour (Russian: зерцало, zertsalo, meaning "mirror"; Chinese: 护心镜, hùxīnjìng, meaning "protect-heart mirror"), sometimes referred to as disc armour or as chahār-āyneh or char-aina (Persian: چهارآینه meaning "four mirrors"; whence Kazakh: шар-айна, şar-ayna), is a type of cuirass that was used mainly in Asia and Eastern Europe, including India, Iran, Tibet, Russia, and the Ottoman Empire.

Key takeaways

  • Mirror armour belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Mirror armour to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Mirror armour (Russian: зерцало, zertsalo, meaning "mirror"; Chinese: 护心镜, hùxīnjìng, meaning "protect-heart mirror"), sometimes referred to as disc armour or as chahār-āyneh or char-aina (Persian: چهارآینه meaning "four mirrors"; whence Kazakh: шар-айна, şar-ayna), is a type of cuirass that was used mainly in Asia and Eastern Europe, including India, Iran, Tibet, Russia, and the Ottoman Empire. It literally translates to "four mirrors" which is a reflection of how these pieces look, resembling four (sometimes more) metal discs or rectangular armour plates. Mirror armor was used in some cultures up to the 20th century.

Description and history "Mirror armour" is a type of partial plate armour which was developed initially from round metal mirrors (a kind of rondel) worn over other armour (usually over mail) as reinforcement. Metal mirrors in this armour were considered as protection from not only cold steel and arrows, but also supernatural influence. It was believed that mirrors could reflect the evil eye, so they were polished and worn over other armour. Early mirror armour consisted of a round mirror attached to the body with a few leather laces (similar to the Roman phaelerae). In Europe, they were known as kardiophylax (Greek) or apezak (Armenian) and were popular with various Bronze Age civilizations, as well as the Central Asian tribes such as the Saka and Yuezhi, and also among the Sasanians. The Kardiophylax was used by the Samnites before they developed the triple-disc cuirass. Although, it continued to be used as a Status symbol after it was discontinued from popular use. This armor would go on to be used by Salian priests as a form of ritual dress. Late mirror armour took the form of a mirror cuirass, helmet, greaves, and bracers worn with mail. There were two alternative constructions of mirror cuirass:

with discs – two large round mirrors surrounded by smaller mirror plates, such as the Klivanion. without discs – typically having four mirror plates – frontplate, backplate, and two sideplates joined by hinges or laces. Early types of this armour were known among the Celtiberians, by the Romans, in West Asia, Central Asia, India, Russia, Siberia (where it was worn by Siberian natives before the Russian conquest), Mongolia, Indochina and China (including Tibet). Later types of this armour were known in West and Central Asia, India, and Russia. The mirror cuirass with discs was popular in Turkey and Russia, while that without discs was popular in Iran, Central Asia and India. In India, there was a popular form of brigandine with a few mirror plates riveted to it. According to Bobrov, round metal mirrors worn by Mongolian warriors as armour reinforcement are shown in Persian miniatures of 13c. This is verified by archaeological finds in Central and East Asia. This kind of armour prevailed in Central Asia during 15–17c, and could be worn over any armour including brigandines, lamellar armour, chainmail and even plated mail. In 16c Iran, mirror plates became much larger and changed their shape to rectangular in order to improve body protection. This improved mirror armour gradually spread during 16–17c to Central Asia and North India. Further improvements were made during the 1640s when mirror plates evolved into mirror cuirass, which sometimes had additional mirror plates used as pauldrons for protection of the shoulder laces. Besides separate mirror plates laced as reinforcement to other armours there were small mirrors that were sewn or riveted to brigandine. Brigandines with such integral reinforcements were very popular at the end of the 15th century, but their use had practically been abandoned by the end of the 17th century. Many modern army ballistic vests resemble the "Chahar-Aine" layout with basic soft anti-fragmentation armour (analogue of chain mail) covering a large area, and two, four or even more bulletproof plates ("mirrors") worn above it, thus combining weight saving and freedom of movement with high level of protection of vital areas. Ottoman 15th to 16th century mirror armour is commonly referred to as "Krug", while the name for the same type of armour in Russia is зерцало (zertsalo), and the modern technical term is зерцальный доспех (zertsal'niy dospekh), from the Russian зерцальный (zertsal'niy) – "mirror"; and Russian: доспех (dospekh) – "armour".

Zertsalo consisted of a number plates that formed the two halves: front and rear. Each sides consists of: a middle plate called the "krug" (rondel), side plates, upper plates (above the "krug") called "ozherelie" (gorget) and "obruch" (ring) enveloping the neck; the front side additionally had "naramki" – shoulder strappings, and the back side had – "naplechniki" (pauldrons) Зерцало состояло из ряда досок, образовавших две половины – переднюю и заднюю. Каждую половину составляли: средняя доска, или круг, боковые дощечки, верхние (над кругом), или ожерелье, и обруч – часть, обхватывающая шею; у передней половины были еще нарамки – плечевые скрепления, а у задней – наплечки

Worked examples

Example 1 — a first encounter with Mirror armour

Start with the simplest possible case. Write down what Mirror armour claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mirror armour before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mirror armour ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mirror armour

In research
Mirror armour appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Mirror armour in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Mirror armour is common in secondary-school and first-year university syllabi. It links to neighbouring topics Asian armour, Mirrors, so understanding it makes those chapters shorter.
In everyday life
Look for Mirror armour outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
