What Is Mirror Writing A Sign Of

Mirror writing on the hood of an ambulance in the United Kingdom. The same word, "AMBULANCE", appears with identical typography, but reading in the normal direction, on the front of the vehicle near the top.

Mirror writing is formed by writing in the direction that is the reverse of the natural way for a given language, such that the result is the mirror image of normal writing: it appears normal when it is reflected in a mirror. It is sometimes used as an extremely primitive form of cipher. A common modern usage of mirror writing can be found on the front of ambulances, where the word "AMBULANCE" is often written in very large mirrored text, so that drivers see the word the right way around in their rear-view mirror.

Some people are able to produce handwritten mirrored text. Notably, Leonardo da Vinci wrote most of his personal notes in this way. Mirror writing calligraphy was popular in the Ottoman Empire, where it often carried mystical associations.

Ability to write mirrored text [edit]

An informal Australian newspaper experiment identified 10 true mirror-writers in a readership of 65,000.[1] A higher proportion of left-handed people are better mirror writers than right-handed people, perhaps because it is more natural for a left-hander to write backwards.[2] 15% of left-handed people have the language centres in both halves of their brain. The cerebral cortex and motor homunculus are affected by this, causing the person to be able to read and write backwards quite naturally.

In an experiment conducted by the Department of Neurosurgery at Hokkaido University School of Medicine in Sapporo, Japan, scientists proposed that the origin of mirror writing comes from damage caused through accidental brain damage or neurological diseases, such as an essential tremor, Parkinson's disease, or spino-cerebellar degeneration. This hypothesis was proposed because these conditions affect a "neural mechanism that controls the higher cerebral function of writing via the thalamus."[3] Another study by the same university discovered that damage was not the only cause. The scientists observed that normal children exhibited signs of mirror writing while learning to write, thus concluding that currently there is no exact method for finding the true origin of mirror writing.

As with left-handedness, mirror writing is sometimes "corrected" in children.

Notable examples [edit]

Leonardo da Vinci wrote most of his personal notes in mirror, only using standard writing if he intended his texts to be read by others. The purpose of this practice by Leonardo remains unknown, though several possible reasons have been suggested. For example, writing left handed from left to right would have been messy because the ink just put down would smear as his hand moved across it. Writing in reverse would prevent such smudging. An alternative theory is that the process of rotating the linguistic object in memory before setting it to paper, and rotating it before reading it back, is a method of reinforcement learning. From this theory, it follows the use of boustrophedonic writing, especially in public codes, may be to render better recall of the text in the reader.[ citation needed ]

Matteo Zaccolini may have written his original four volume treatise on optics, color, and perspective in the early 17th century in mirror script.[ citation needed ]

Pictorial texts also known as calligrams arranged in mirror symmetry were popular in the Ottoman Empire during the 18th and 19th centuries among the Bektashi order, where it often carried mystical associations.[4] The origins of this mirror writing tradition may date to the pre-Islamic period in rock inscriptions of the western Arabian peninsula.[4] A recent study that has revealed the oldest examples of mirror writing in Greek traces the early appearance of mirror inscriptions to Late Antiquity, specifically to Syria-Palestine, Egypt, and Constantinople. In Islamic art, mirror calligraphy is known as muthanna or musenna.[5]
