Thousands of clay tablets survive from ancient Mesopotamia. Some record deliveries of grain. Others contain contracts, letters, school exercises, mathematical problems, medical treatments, observations of the sky, prayers and stories about gods and heroes.
Together, they preserve an extraordinary range of human activity.
The earliest securely attested writing in southern Mesopotamia dates to the late fourth millennium BC, at roughly the same broad period that writing was also emerging independently in ancient Egypt. This article follows the Mesopotamian tradition: one of the earliest and best documented histories of writing in the ancient world.
What began largely as a practical way of keeping records eventually became capable of preserving almost anything people wanted to communicate.
Writing for everyday needs
The earliest surviving writing from southern Mesopotamia is closely connected with the growth of cities and increasingly complicated systems of administration.
By around 3300 BC, places such as Uruk had become large urban centres. Temples, households and other institutions had to manage workers, livestock, crops and goods on a scale that was difficult to keep track of through memory alone. Many early tablets are therefore intensely practical, recording quantities of grain, animals, rations, labour and other economic information.
These early texts did not yet look like the dense lines of wedge-shaped writing that we normally associate with Mesopotamia. Many signs began as simplified pictures and numerical marks made in clay. Over time, both the signs and the way they were written changed, becoming increasingly abstract and better suited to recording language.
How cuneiform was written
Clay was abundant in Mesopotamia, making it an inexpensive and convenient writing material. A scribe could shape wet clay into a small tablet and mark its surface before it dried.
Early signs were often drawn into the clay. Over time, scribes increasingly impressed marks with a stylus, producing the distinctive triangular and wedge-shaped forms from which cuneiform gets its modern name. The word comes from the Latin for “wedge-shaped”.
Instead of drawing continuous lines, the writer pressed different parts of the stylus into the soft surface. By arranging these impressions in different directions and combinations, hundreds of signs could be formed.
Reeds were commonly used for writing on clay, although surviving writing tools show that other materials could also be used. The way scribes wrote helped shape the appearance of the script.
Over the centuries, cuneiform signs came to represent not only objects and ideas but also sounds. That development allowed scribes to write language much more fully and opened the system to uses far beyond accounting.
Learning to write
Cuneiform was not a simple alphabet. Depending on the period and language, scribes had to learn hundreds of signs, and a single sign might represent a word, a syllable or different sounds depending on context.
Becoming a skilled scribe therefore required extensive training.
Surviving school tablets allow us to see parts of that education directly. Students practised individual signs, syllables, names and vocabulary before moving on to longer passages and more difficult texts. On some exercises, a teacher wrote a model and the pupil copied it nearby or on the other side of the tablet.
Training also involved learning established lists of words and signs that had been copied for generations. Advanced students could go on to copy literary and scholarly works as part of their education.
Sumerian remained important in scribal culture long after it had ceased to be widely spoken in everyday life. Later scribes continued studying it because important religious, literary and scholarly traditions were written in the language.
Learning to write in Mesopotamia was therefore not simply about learning how to make signs. It meant entering a long-established scholarly tradition.
Writing for work, law and communication
As cuneiform became capable of representing language more fully, its uses expanded enormously.
Clay tablets were used for contracts, receipts, loans, property transactions, legal agreements, court records and correspondence. Kings and officials used writing to communicate orders, while merchants, households and families also relied on it for everyday business and personal matters.
Thousands of letters survive from the ancient Near East. Some concern government, diplomacy or military affairs, while others deal with money, goods, work and family concerns.
That makes written correspondence particularly valuable to historians. A royal monument was created to present power publicly, but a letter could preserve something much more immediate: a request, a complaint, an instruction or an argument between people who expected the message to matter only to its recipient.
Practical writing remained important throughout the history of cuneiform. Even while scholars copied hymns and stories about gods and legendary kings, other scribes were recording debts, deliveries and administrative decisions.
Putting knowledge into writing
Mesopotamian scholars also used writing to organise and preserve knowledge. Tablets survive containing mathematical calculations, medical material, vocabulary lists, observations of animals and plants, and records of celestial events.
Astronomy became an especially sophisticated field of Babylonian scholarship.
Across generations, scholars observed the movements of the Moon, planets and stars and recorded what they saw. Some of this work was closely connected with divination and the interpretation of celestial signs, while other texts developed increasingly systematic methods for calculating and predicting astronomical events.
These ancient traditions do not fit neatly into modern categories such as “science”, and there's no need to force them to. What matters is that writing allowed observations and calculations to accumulate over long periods.
A later scholar could consult, copy and compare records created by people who had lived decades or centuries earlier. The same principle applied in fields such as mathematics, medicine and language study, allowing bodies of knowledge to develop beyond a single lifetime.
Cuneiform travelled
Cuneiform was never tied permanently to one language or one kingdom.
It first developed in southern Mesopotamia and was used for Sumerian, but later became especially important for Akkadian and its Babylonian and Assyrian forms. Other peoples across the ancient Near East adapted cuneiform for their own languages as well.
At its widest extent, the script was used across a huge area stretching from Anatolia and the Mediterranean to western Iran. It was adapted to write numerous languages over the course of its long history.
Cuneiform also survived for an extraordinary length of time. It remained in use for more than three thousand years. The latest securely dated cuneiform texts come from the first century AD, although the script may have remained in limited use for longer.
During those millennia, kingdoms rose and fell, languages changed and political centres shifted. The writing system changed too, but remained part of a recognisable scribal tradition stretching back to the earliest cities of southern Mesopotamia.
From records to stories
One of the most striking developments in the history of Mesopotamian writing was its use for literature.
A system that had developed in close connection with administration eventually preserved hymns, prayers, myths, lamentations and poems. By the third millennium BC, writing was being used not only to record goods and labour but also to represent language in increasingly sophisticated ways.
These texts open a very different window onto Mesopotamian life. Administrative records tell us what people received, owed or delivered; literary texts show some of the ways people thought about kingship, mortality, friendship, divine power and the relationship between human beings and the gods.
The most famous surviving example is the Epic of Gilgamesh.
The epic developed over a long period from earlier stories and traditions surrounding Gilgamesh, a legendary king of Uruk. The best-known surviving version was written in Akkadian and preserved across a series of tablets.
It tells of Gilgamesh and his companion Enkidu, their adventures, Enkidu’s death and Gilgamesh’s search for a way to escape mortality.
One tablet contains the famous flood narrative told to Gilgamesh by Utnapishtim. The surviving copy formed part of the great collection assembled at Nineveh by the Assyrian king Ashurbanipal in the seventh century BC.
The distance between an early grain account and the Epic of Gilgamesh is enormous, but both belong to the same long history of writing on clay.
What the tablets left behind
Clay was an ordinary material, and that's one reason so much Mesopotamian writing survived.
Many tablets were dried rather than deliberately fired. Some tablets hardened as they dried, while others were accidentally fired when buildings burned. Broken tablets could also survive in rubbish deposits, foundations and the ruins of abandoned settlements.
Vast numbers of cuneiform tablets have been recovered across the ancient Near East, preserving everything from royal inscriptions to school exercises, astronomical records and routine accounts.
That variety is one of their greatest strengths as historical evidence. Mesopotamian writing does not preserve only kings and battles. It preserves administration, education, work, scholarship, religion, private communication and stories.
Over thousands of years, the same basic writing tradition could be used to record a delivery of barley, teach a student how to write, calculate the movement of a planet or preserve a story about friendship, grief and the fear of death.
That range is what makes the written world of Mesopotamia so remarkable.
