History of writing Information
|Part of a series on|
|↑ Prehistory ( Pleistocene epoch)|
The history of writing traces the development of expressing language by systems of markings. 
In the history of how writing systems have evolved in human civilizations, more complete writing systems were preceded by proto-writing, systems of ideographic or early mnemonic symbols (symbols or letters that make remembering them easier). True writing, in which the content of a linguistic utterance is encoded so that another reader can reconstruct, with a fair degree of accuracy, the exact utterance written down, is a later development. It is distinguished from proto-writing, which typically avoids encoding grammatical words and affixes, making it more difficult or even impossible to reconstruct the exact meaning intended by the writer unless a great deal of context is already known in advance.
Writing was long thought to have been invented in a single civilization, a theory named "monogenesis".  Scholars believed that all writing originated in ancient Sumer (in Mesopotamia) and spread over the world from there via a process of cultural diffusion.  According to this theory, the concept of representing language by written marks, though not necessarily the specifics of how such a system worked, was passed on by traders or merchants traveling between geographical regions. [a] 
However, the discovery of the scripts of ancient Mesoamerica, far away from Middle Eastern sources, proved that writing had been invented more than once. Scholars now recognize that writing may have independently developed in at least four ancient civilizations: Mesopotamia (between 3400 and 3100 BCE), Egypt (around 3250 BCE),    China (1200 BCE),  and lowland areas of Southern Mexico and Guatemala (by 500 BCE). 
Regarding ancient Egypt, several scholars    have argued that "the earliest solid evidence of Egyptian writing differs in structure and style from the Mesopotamian and must therefore have developed independently. The possibility of 'stimulus diffusion' from Mesopotamia remains, but the influence cannot have gone beyond the transmission of an idea."  
Regarding China, it is believed that ancient Chinese characters are an independent invention because there is no evidence of contact between ancient China and the literate civilizations of the Near East,  and because of the distinct differences between the Mesopotamian and Chinese approaches to logography and phonetic representation. 
Debate surrounds the Indus script of the Bronze Age Indus Valley civilisation, the Rongorongo script of Easter Island, and the Vinča symbols dated around 5500 BCE. All are undeciphered, and so it is unknown if they represent authentic writing, proto-writing, or something else.
The Sumerian archaic (pre- cuneiform) writing and Egyptian hieroglyphs are generally considered the earliest true writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400–3100 BCE, with earliest coherent texts from about 2600 BCE. The Proto-Elamite script is also dated to the same approximate period. 
Symbolic communication systems are distinguished from writing systems. With writing systems, one must usually understand something of the associated spoken language to comprehend the text. In contrast, symbolic systems, such as information signs, painting, maps, and mathematics, often do not require prior knowledge of a spoken language. Every human community possesses language, a feature regarded by many as an innate and defining condition of humanity (see Origin of language). However the development of writing systems, and their partial replacement of traditional oral systems of communication, have been sporadic, uneven, and slow. Once established, writing systems on the whole change more slowly than their spoken counterparts and often preserve features and expressions that no longer exist in the spoken language.
There are considered to be three writing criteria for all writing systems. Firstly, writing must be complete: it must have a purpose or some sort of meaning to it, and a point must be made or communicated in the text. Secondly, all writing systems must have some sort of symbols which can be made on some sort of surface, whether physical or digital. Lastly, the symbols used in the writing system must mimic spoken word/speech, in order for communication to be possible. 
The greatest benefit of writing is that it provides the tool by which society can record information consistently and in greater detail, something that could not be achieved as well previously by spoken word. Writing allows societies to transmit information and to share and preserve knowledge.
The origins of writing appear during the start of the pottery-phase of the Neolithic, when clay tokens were used to record specific amounts of livestock or commodities.  These tokens were initially impressed on the surface of round clay envelopes and then stored in them.  The tokens were then progressively replaced by flat tablets, on which signs were recorded with a stylus. Actual writing is first recorded in Uruk, at the end of the 4th millennium BCE, and soon after in various parts of the Near East. 
An ancient Mesopotamian poem gives the first known story of the invention of writing:
Because the messenger's mouth was heavy and he couldn't repeat (the message), the Lord of Kulaba patted some clay and put words on it, like a tablet. Until then, there had been no putting words on clay.
Scholars make a reasonable distinction between prehistory and history of early writing  but have disagreed concerning when prehistory becomes history and when proto-writing became "true writing". The definition is largely subjective.  Writing, in its most general terms, is a method of recording information and is composed of graphemes, which may, in turn, be composed of glyphs. 
The emergence of writing in a given area is usually followed by several centuries of fragmentary inscriptions. Historians mark the "historicity" of a culture by the presence of coherent texts in the culture's writing system(s). 
A conventional "proto-writing to true writing" system follows a general series of developmental stages:
- Picture writing system: glyphs (simplified pictures) directly represent objects and concepts. In connection with this, the following substages may be distinguished:
- Mnemonic: glyphs primarily as a reminder.
- Pictographic: glyphs directly represent an object or a concept such as (A) chronological, (B) notices, (C) communications, (D) totems, titles, and names, (E) religious, (F) customs, (G) historical, and (H) biographical.
- Ideographic: graphemes are abstract symbols that directly represent an idea or concept.
- Transitional system: graphemes refer not only to the object or idea that it represents but to its name as well.
- Phonetic system: graphemes refer to sounds or spoken symbols, and the form of the grapheme is not related to its meanings. This resolves itself into the following substages:
- Verbal: grapheme ( logogram) represents a whole word.
- Syllabic: grapheme represents a syllable.
- Alphabetic: grapheme represents an elementary sound.
- Jiahu symbols, carved on tortoise shells in Jiahu, c. 6600 BCE
- Vinča symbols ( Tărtăria tablets), c. 5300 BCE 
- Early Indus script, c. 3100 BCE
The history of literature begins with the history of writing, but literature and writing, though obviously connected, are not synonymous. The very first writings from ancient Sumer by any reasonable definition do not constitute literature. The same is true of some of the early Egyptian hieroglyphics and the thousands of ancient Chinese government records. Scholars have disagreed concerning when written record-keeping became more like literature, but the oldest surviving literary texts date from a full millennium after the invention of writing. The earliest literary author known by name is Enheduanna, who is credited as the author of a number of works of Sumerian literature, including Exaltation of Inanna, in the Sumerian language during the 24th century BC.   The next earliest named author is Ptahhotep, who is credited with authoring The Maxims of Ptahhotep, an instructional book for young men in Egyptian composed in the 23rd century BC. 
The first writing systems of the Early Bronze Age were not a sudden invention. Rather, they were a development based on earlier traditions of symbol systems that cannot be classified as proper writing, but have many of the characteristics of writing. These systems may be described as "proto-writing". They used ideographic or early mnemonic symbols to convey information, but it probably directly contained no natural language. These systems emerged in the early Neolithic period, as early as the 7th millennium BC, and include:
- The Jiahu symbols found carved in tortoise shells in 24 Neolithic graves excavated at Jiahu, Henan province, northern China, with radiocarbon dates from the 7th millennium BCE.  Most archaeologists consider these not directly linked to the earliest true writing. 
- Vinča symbols, sometimes called the "Danube script", are a set of symbols found on Neolithic era (6th to 5th millennia BCE) artifacts from the Vinča culture of Central Europe and Southeast Europe. 
- The Dispilio Tablet of the late 6th millennium may also be an example of proto-writing.
- The Indus script, which from 3500 BCE to 1900 BCE was used for extremely short inscriptions.
Even after the Neolithic, several cultures went through an intermediate stage of proto-writing before they used proper writing. The quipu of the Incas (15th century CE), sometimes called "talking knots", may have been such a system. Another example is the pictographs invented by Uyaquk before the development of the Yugtun syllabary for the Central Alaskan Yup'ik language in about 1900.
Writing emerged in many different cultures in the Bronze Age. Examples are the cuneiform writing of the Sumerians, Egyptian hieroglyphs, Cretan hieroglyphs, Chinese logographs, Indus script, and the Olmec script of Mesoamerica. The Chinese script likely developed independently of the Middle Eastern scripts around 1600 BCE. The pre-Columbian Mesoamerican writing systems (including Olmec and Maya scripts) are also generally believed to have had independent origins. It is thought that the first true alphabetic writing was developed around 2000 BCE for Semitic workers in the Sinai by giving mostly Egyptian hieratic glyphs Semitic values (see History of the alphabet and Proto-Sinaitic alphabet). The Geʽez writing system of Ethiopia is considered Semitic. It is likely to be of semi-independent origin, having roots in the Meroitic Sudanese ideogram system.  Most other alphabets in the world today either descended from this one innovation, many via the Phoenician alphabet, or were directly inspired by its design. In Italy, about 500 years passed from the early Old Italic alphabet to Plautus (c. 750–250 BCE), and in the case of the Germanic peoples, the corresponding time span is again similar, from the first Elder Futhark inscriptions to early texts like the Abrogans (c. 200–750 CE).
The original Sumerian writing system derives from a system of clay tokens used to represent commodities. By the end of the 4th millennium BC, this had evolved into a method of keeping accounts, using a round-shaped stylus impressed into soft clay at different angles for recording numbers. This was gradually augmented with pictographic writing by using a sharp stylus to indicate what was being counted. By the 29th century BCE, writing, at first only for logograms, using a wedge-shaped stylus (hence the term cuneiform) developed to include phonetic elements, gradually replacing round-stylus and sharp-stylus writing by around 2700–2500 BCE. About 2600 BCE, cuneiform began to represent syllables of the Sumerian language. Finally, cuneiform writing became a general purpose writing system for logograms, syllables, and numbers. From the 26th century BCE, this script was adapted to the Akkadian language, and from there to others, such as Hurrian and Hittite. Scripts similar in appearance to this writing system include those for Ugaritic and Old Persian.
Writing was very important in maintaining the Egyptian empire, and literacy was concentrated among an educated elite of scribes.[ citation needed] Only people from certain backgrounds were allowed to train as scribes, in the service of temple, royal ( pharaonic), and military authorities.
Geoffrey Sampson stated that Egyptian hieroglyphs "came into existence a little after Sumerian script, and, probably [were], invented under the influence of the latter",  and that it is "probable that the general idea of expressing words of a language in writing was brought to Egypt from Sumerian Mesopotamia".   Despite the importance of early Egypt–Mesopotamia relations, given the lack of direct evidence "no definitive determination has been made as to the origin of hieroglyphics in ancient Egypt".  Instead, it is pointed out and held that "the evidence for such direct influence remains flimsy" and that "a very credible argument can also be made for the independent development of writing in Egypt". 
Since the 1990s, the discoveries of glyphs at Abydos, dated to between 3400 and 3200 BCE, may challenge the classical notion according to which the Mesopotamian symbol system predates the Egyptian one, although Egyptian writing does make a sudden appearance at that time, while on the contrary Mesopotamia has an evolutionary history of sign usage in tokens dating back to circa 8000 BCE.    These glyphs, found in tomb U-J at Abydos are written on ivory and are likely labels for other goods found in the grave. 
Egyptian scholar Gamal Mokhtar argued that the inventory of hieroglyphic symbols derived from "fauna and flora used in the signs [which] are essentially African" and in "regards to writing, we have seen that a purely Nilotic, hence African origin not only is not excluded, but probably reflects the reality" although he acknowledged the geographical location of Egypt made it a receptacle for many influences. 
The undeciphered Proto-Elamite script emerges from as early as 3100 BCE. It is believed to have evolved into Linear Elamite by the later 3rd millennium and then replaced by Elamite Cuneiform adopted from Akkadian.
Markings and symbols found at various sites of the Indus Valley civilisation have been labelled as the Indus script citing the possibility that they were used for transcribing the Harappan language.  Whether the script, which was in use from about 3500–1900 BCE, constitutes a Bronze Age writing script (logographic-syllabic) or proto-writing symbols is debated as it has not yet been deciphered. It is analyzed to have been written from right-to-left or in boustrophedon. 
The first " abjads", mapping single symbols to single phonemes but not necessarily each phoneme to a symbol, emerged around 1800 BCE in Ancient Egypt, as a representation of language developed by Semitic workers in Egypt, but by then alphabetic principles had a slight possibility of being inculcated into Egyptian hieroglyphs for upwards of a millennium.[ clarification needed] These early abjads remained of marginal importance for several centuries, and it is only towards the end of the Bronze Age that the Proto-Sinaitic script splits into the Proto-Canaanite alphabet (c. 1400 BCE) Byblos syllabary and the South Arabian alphabet (c. 1200 BCE). The Proto-Canaanite was probably somehow influenced by the undeciphered Byblos syllabary and, in turn, inspired the Ugaritic alphabet (c. 1300 BCE).
Anatolian hieroglyphs are an indigenous hieroglyphic script native to western Anatolia, used to record the Hieroglyphic Luwian language. It first appeared on Luwian royal seals from the 14th century BCE.
The earliest confirmed evidence of the Chinese script yet discovered is the body of inscriptions on oracle bones and bronze from the late Shang dynasty. The earliest of these is dated to around 1200 BCE.  
There have recently been discoveries of tortoise-shell carvings dating back to c. 6000 BCE, like Jiahu Script, Banpo Script, but whether or not the carvings are complex enough to qualify as writing is under debate.  At Damaidi in the Ningxia Hui Autonomous Region, 3,172 cliff carvings dating to c. 6000–5000 BCE have been discovered, featuring 8,453 individual characters, such as the sun, moon, stars, gods, and scenes of hunting or grazing. These pictographs are reputed to be similar to the earliest characters confirmed to be written Chinese. If it is deemed to be a written language, writing in China will predate Mesopotamian cuneiform, long acknowledged as the first appearance of writing, by some 2,000 years; however it is more likely that the inscriptions are rather a form of proto-writing, similar to the contemporary European Vinca script.
Cretan hieroglyphs are found on artifacts of Crete (early-to-mid-2nd millennium BCE, MM I to MM III, overlapping with Linear A from MM IIA at the earliest). Linear B, the writing system of the Mycenaean Greeks,  has been deciphered while Linear A has yet to be deciphered. The sequence and the geographical spread of the three overlapping, but distinct, writing systems can be summarized as follows: [b] 
|Writing system||Geographical area||Time span|
|Cretan Hieroglyphic||Crete (eastward from the Knossos-Phaistos axis)||c. 2100−1700 BCE|
|Linear A||Crete (except extreme southwest), Aegean Islands ( Kea, Kythera, Melos, Thera), and Greek mainland ( Laconia)||c. 1800−1450 BCE|
|Linear B||Crete ( Knossos), and mainland ( Pylos, Mycenae, Thebes, Tiryns)||c. 1450−1200 BCE|
A stone slab with 3,000-year-old writing, the Cascajal Block, was discovered in the Mexican state of Veracruz, and is an example of the oldest script in the Western Hemisphere, preceding the oldest Zapotec writing dated to about 500 BCE.   
Of several pre-Columbian scripts in Mesoamerica, the one that appears to have been best developed, and has been fully deciphered, is the Maya script. The earliest inscriptions which are identifiably Maya date to the 3rd century BCE, and writing was in continuous use until shortly after the arrival of the Spanish conquistadores in the 16th century CE. Maya writing used logograms complemented by a set of syllabic glyphs: a combination somewhat similar to modern Japanese writing.
The Phoenician alphabet is simply the Proto-Canaanite alphabet as it was continued into the Iron Age (conventionally taken from a cut-off date of 1050 BCE).[ citation needed] This alphabet gave rise to the Aramaic and Greek alphabets. These in turn led to the writing systems used throughout regions ranging from Western Asia to Africa and Europe. For its part the Greek alphabet introduced for the first time explicit symbols for vowel sounds.  The Greek and Latin alphabets in the early centuries of the Common Era gave rise to several European scripts such as the Runes and the Gothic and Cyrillic alphabets while the Aramaic alphabet evolved into the Hebrew, Arabic and Syriac abjads, of which the latter spread as far as Mongolian script. The South Arabian alphabet gave rise to the Ge'ez abugida. The Brahmic family of India is believed by some scholars to have derived from the Aramaic alphabet as well. 
A previously unknown script was discovered in 2015 in Georgia, over the Grakliani Hill just below a temple's collapsed altar to a fertility goddess from the seventh century BCE. These inscriptions differ from those at other temples at Grakliani, which show animals, people, or decorative elements.   The script bears no resemblance to any alphabet currently known, although its letters are conjectured to be related to ancient Greek and Aramaic.  The inscription appears to be the oldest native alphabet to be discovered in the whole Caucasus region,  In comparison, the earliest Armenian and Georgian script date from the fifth century CE, just after the respective cultures converted to Christianity. By September 2015, an area of 31 by 3 inches of the inscription had been excavated. 
According to Vakhtang Licheli, head of the Institute of Archaeology of the State University, "The writings on the two altars of the temple are really well preserved. On the one altar several letters are carved in clay while the second altar's pedestal is wholly covered with writings."  The finding was made by unpaid students.[ citation needed] In 2016 Grakliani Hill inscriptions were taken to Miami Laboratory for Beta analytic radiocarbon dating which found that the inscriptions were made in c. 1005 – c. 950 BCE.[ citation needed]
The history of the Greek alphabet began in at least the early 8th century BCE when the Greeks adapted the Phoenician alphabet for use with their own language.  The letters of the Greek alphabet are more or less the same as those of the Phoenician alphabet, and in modern times both alphabets are arranged in the same order.  The adapter(s) of the Phoenician system added three letters to the end of the series, called the "supplementals". Several varieties of the Greek alphabet developed. One, known as Western Greek or Chalcidian, was used west of Athens and in southern Italy. The other variation, known as Eastern Greek, was used in present-day Turkey and by the Athenians, and eventually the rest of the world that spoke Greek adopted this variation. After first writing right to left, like the Phoenicians, the Greeks eventually chose to write from left to right. Occasionally however, the writer would start the next line where the previous line finished, so that the lines would read alternately left to right, then right to left, and so on. This was known as "boustrophedon" writing, which imitated the path of an ox-drawn plough, and was used until the sixth century. 
Greek is in turn the source for all the modern scripts of Europe. The most widespread descendant of Greek is the Latin script, named for the Latins, a central Italian people who came to dominate Europe with the rise of Rome. The Romans learned writing in about the 5th century BCE from the Etruscan civilization, who used one of a number of Italic scripts derived from the western Greeks. Due to the cultural dominance of the Roman state, the other Old Italic scripts have not survived in any great quantity, and the Etruscan language is mostly lost.
With the collapse of the Roman authority in Western Europe, literary development became largely confined to the Eastern Roman Empire and the Persian Empire. Latin, never one of the primary literary languages, rapidly declined in importance (except within the Roman Catholic Church). The primary literary languages were Greek and Persian, though other languages such as Syriac and Coptic were important too.
The rise of Islam in the 7th century led to the rapid rise of Arabic as a major literary language in the region. Arabic and Persian quickly began to overshadow Greek's role as a language of scholarship. Arabic script was adopted as the primary script of the Persian language and the Turkish language. This script also heavily influenced the development of the cursive scripts of Greek, the Slavic languages, Latin, and other languages.[ citation needed] The Arabic language also served to spread the Hindu–Arabic numeral system throughout Europe.[ citation needed] By the beginning of the second millennium, the city of Córdoba in modern Spain had become one of the foremost intellectual centers of the world and contained the world's largest library at the time.  Its position as a crossroads between the Islamic and Western Christian worlds helped fuel intellectual development and written communication between both cultures.
By the 14th century a rebirth, or renaissance, had emerged in Western Europe, leading to a temporary revival of the importance of Greek, and a slow revival of Latin as a significant literary language. A similar though smaller emergence occurred in Eastern Europe, especially in Russia. At the same time Arabic and Persian began a slow decline in importance as the Islamic Golden Age ended. The revival of literary development in Western Europe led to many innovations in the Latin alphabet and the diversification of the alphabet to codify the phonologies of the various languages.
The nature of writing has been constantly evolving, particularly due to the development of new technologies over the centuries. The pen, the printing press, the computer and the mobile phone are all technological developments which have altered what is written, and the medium through which the written word is produced. Particularly with the advent of digital technologies, namely the computer and the mobile phone, characters can be formed by the press of a button, rather than making a physical motion with the hand.
There is no very definite statement as to the material which was in most common use for the purposes of writing at the start of the early writing systems.  In all ages it has been customary to engrave on stone or metal, or other durable material, with the view of securing the permanency of the record. Metals, such as stamped coins, are mentioned as a material of writing; they include lead, [c] brass, and gold. There are also references to the engraving of gems, such as with seals or signets. 
The common materials of writing were the tablet and the roll, the former probably having a Chaldean origin, the latter an Egyptian. The tablets of the Chaldeans are small pieces of clay, somewhat crudely shaped into a form resembling a pillow, and thickly inscribed with cuneiform characters. [d] Similar use has been seen in hollow cylinders, or prisms of six or eight sides, formed of fine terracotta, sometimes glazed, on which the characters were traced with a small stylus, in some specimens so minutely as to require the aid of a magnifying-glass. 
In Egypt the principal writing material was of quite a different sort. Wooden tablets are found pictured on the monuments; but the material which was in common use, even from very ancient times, was the papyrus, having recorded use as far back as 3,000 BCE.  This reed, found chiefly in Lower Egypt, had various economic means for writing. The pith was taken out and divided by a pointed instrument into the thin pieces of which it is composed; it was then flattened by pressure, and the strips glued together, other strips being placed at right angles to them, so that a roll of any length might be manufactured. Writing seems to have become more widespread with the invention of papyrus in Egypt. That this material was in use in Egypt from a very early period is evidenced by still existing papyrus of the earliest Theban dynasties.  As the papyrus, being in great demand, and exported to all parts of the world, became very costly, other materials were often used instead of it, among which is mentioned leather, a few leather mills of an early period having been found in the tombs.  Parchment, using sheepskins left after the wool was removed for cloth, was sometimes cheaper than papyrus, which had to be imported outside Egypt. With the invention of wood-pulp paper, the cost of writing material began a steady decline. Wood-pulp paper is still used today, and in recent times efforts have been made in order to improve bond strength of fibers. Two main areas of examination in this regard have been "dry strength of paper" and "wet web strength".  The former involves examination of the physical properties of the paper itself, while the latter involves using additives to improve strength.

The same material was largely used by the Assyrians, and many of their clay tablets still remain. They are of various sizes, ranging from nine inches long by six and a half wide, to an inch and a half by an inch wide, and even less. Some thousands of these have been recovered; many are historical, some linguistic, some geographical, some astronomical.

A block with a hitherto unknown system of writing has been found in the Olmec heartland of Veracruz, Mexico. Stylistic and other dating of the block places it in the early first millennium before the common era, the oldest writing in the New World, with features that firmly assign this pivotal development to the Olmec civilization of Mesoamerica.
