How Cuneiform Changed Life in Early Cities

By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.

The earliest cities created a problem that memory alone could not solve. Grain, animals, workers, taxes and debts all had to be tracked across large communities. In ancient Mesopotamia, small marks pressed into clay became one of the world's earliest writing systems.

Records came before long stories

People in Mesopotamia had used clay tokens to represent goods before full writing developed. As cities and temples managed larger stores, officials began recording quantities and objects on clay tablets. Early signs often looked like simplified pictures, but they became more abstract and standardised over time.

Scribes pressed a cut reed stylus into damp clay, creating wedge-shaped marks. The Latin name cuneiform means wedge-shaped. Tablets could be dried for temporary use or baked to make them more durable. Fire sometimes hardened tablets accidentally when buildings burned, which is one reason so many records survived for archaeologists to find.

The first tablets were mainly practical. They listed deliveries, rations, fields and labour. This may sound less thrilling than an epic hero fighting monsters, but administration was the machinery that allowed crowded cities to store food, organise work and settle obligations.

The system learned to represent language

Pictures alone are limited. A drawing of a sheep can represent a sheep, but it struggles with names, actions and abstract ideas. Cuneiform signs gradually gained several uses. A sign could represent an object, an idea, a syllable or a clue about the kind of word nearby.

This flexibility allowed scribes to write spoken languages rather than only label goods. Cuneiform was first developed for Sumerian and was later adapted for Akkadian and other languages. The same sign could have different readings depending on context, which made the system powerful but difficult to master.

Scribal education required years of copying signs, word lists and model texts. Skilled scribes became valuable workers in temples, palaces and trading centres. Writing created opportunities, but access was limited. Most people still experienced written decisions through officials rather than reading the tablets themselves. Scribes also used seals to identify people and protect transactions. A sealed tablet or clay envelope could show whether a record had been opened or altered. Writing therefore supported trust between people who could not all stand in the same room and remember the same agreement.

Clay tablets carried many kinds of knowledge

As cuneiform expanded, people used it for far more than accounting. Surviving tablets reveal both public systems and private concerns:

  • •Laws, court decisions and contracts.
  • •Letters between rulers, merchants and families.
  • •Mathematical tables and school exercises.
  • •Prayers, medical observations and omens.
  • •Stories such as the Epic of Gilgamesh.

How cuneiform was deciphered

Cuneiform fell out of use around the start of the common era, and for centuries nobody could read it. A key to decipherment was a huge inscription carved on a cliff at Behistun in western Iran, commissioned by the Persian king Darius I. It repeats the same text in three languages written in cuneiform: Old Persian, Elamite and Babylonian. Old Persian, which uses a fairly simple set of signs, was cracked first. Scholars could then use it as a key to work on the far more complex Babylonian version.

Henry Rawlinson, a British officer, climbed the cliff and copied much of the inscription in the 1830s and 1840s, and several scholars contributed to reading it. In 1857 the Royal Asiatic Society arranged a test. Four scholars were given copies of a newly found Assyrian inscription and asked to translate it independently. Their versions agreed closely enough to convince doubters that the script had genuinely been deciphered. Since then, hundreds of thousands of tablets have been recovered, many still waiting in museum storerooms for someone to read them.

Counting in sixties, from clay to your watch

Mesopotamian scribes did mathematics as well as accounts, and they did it in base sixty rather than base ten. Sixty is convenient because it divides evenly by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30, which makes fractions much easier to handle when sharing grain or measuring land. The Babylonian system was also positional, meaning the value of a symbol depended on its place, much as the 3 in 300 means something different from the 3 in 30.

School tablets show impressive skill. One small round tablet in the Yale collection, known as YBC 7289, shows a square with its diagonals and gives a value for the square root of two that is accurate to about six decimal places. The legacy of base sixty is still with you. Dividing an hour into sixty minutes and a minute into sixty seconds, and a circle into 360 degrees, comes down through Greek astronomers who borrowed Babylonian methods for their calculations. Each time you read a clock, you are using a counting habit first pressed into clay.

Cuneiform beyond Mesopotamia

Cuneiform did not stay in the cities that invented it. Around 1900 BCE, merchants from the city of Ashur ran a long-distance trade with Kanesh, in central Anatolia, now part of Turkey. Donkey caravans carried tin and woollen textiles north, and the traders were paid in silver and gold. Archaeologists have found over twenty thousand tablets in the merchants' houses there, mostly letters and business records. They discuss debts, partnerships, family quarrels and the work of women in Ashur who wove textiles and managed affairs at home, giving an unusually detailed picture of private commercial life written by ordinary traders rather than kings.

By the fourteenth century BCE, Akkadian written in cuneiform had become the shared language of international diplomacy. In 1887 a local woman digging at Amarna in Egypt found clay tablets that turned out to be letters between pharaohs and the rulers of Babylon, Assyria, the Hittites, Mitanni and cities in the Levant, nearly all written in Akkadian rather than Egyptian. At Ugarit, a trading city on the Syrian coast, scribes went further and created an alphabet of around thirty wedge-shaped signs. It used the technique of cuneiform but worked like an alphabet, showing how one writing tool could be adapted to a completely different system.

From clay tokens to written numbers

How did marks on clay grow out of the earlier token system? The archaeologist Denise Schmandt-Besserat proposed an influential answer. Small clay tokens shaped as cones, spheres, discs and other forms appear at sites in the Near East thousands of years before writing. By the second half of the fourth millennium BCE, some were being sealed inside hollow clay balls, often called envelopes, as a record of a transaction. To show what was inside without breaking the ball, people pressed the tokens into its surface. At some point, it seems, they realised the impressions alone were enough, and flat tablets marked with signs replaced the tokens.

Not every scholar accepts that the path from tokens to tablets was so direct, and many token shapes do not match later signs. The earliest tablets from Uruk reveal another surprise. Scribes used different counting systems for different goods, so grain, livestock and land were counted with separate sets of number signs and different groupings. A number was not yet an abstract idea that could count anything. Only gradually did scribes separate the sign for a quantity from the sign for the thing being counted, a step towards the flexible numbers you use without thinking. Writing and arithmetic developed together, shaped by the needs of administrators.

The takeaway

Cuneiform grew from a tool for managing goods into a system capable of recording language, law and literature. Its history shows that writing was not invented in one finished moment. It developed through many practical changes as people asked clay marks to remember more than any individual person could.
