History

Writing began after pottery was invented, during the Neolithic, when clay tokens were used to record specific amounts of livestock or commodities. In recent years a contrarian view has arisen on the tokens being the precursor of writing. These tokens were initially impressed on the surface of round clay envelopes (clay bullae) and then stored in them. The tokens were then progressively replaced by flat tablets, on which signs were recorded with a stylus. Writing is first recorded in Uruk, at the end of the 4th millennium BC, 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 Lord of Kulaba patted some clay and put words on it, like a tablet. Until then, there had been no putting words on clay.

The cuneiform writing system was in use for more than three millennia, through several stages of development, from the 31st century BC down to the second century AD. The latest firmly dateable tablet, from Uruk, dates to 79/80 AD. Ultimately, it was completely replaced by alphabetic writing, in the general sense, in the course of the Roman era, and there are no cuneiform systems in current use. It had to be deciphered as a completely unknown writing system in 19th-century Assyriology. It was successfully deciphered by 1857.
