جمدة نصر
The Jemdet Nasr tablets are written in proto-cuneiform script. Proto-cuneiform is thought to have arisen in the second half of the 4th millennium BC. While at first it was characterized by a small set of symbols that were predominantly pictographs, by the time of the Jemdet Nasr period, there was already a trend toward more abstract and simpler designs. It is also during this period that the script acquired its iconic wedge-shaped appearance. While the language in which these tablets were written cannot be identified with certainty, it is thought to have been Sumerian. Contemporary archives have been found at Uruk, Tell Uqair and Khafajah.
