17 CBS 11319+: Conclusion
In 2300 BC, much of southern Mesopotamia was united for the first time under Sargon of Akkad. Along with his successors, initiated a set of reforms, which included enforcing the use of the Akkadian language over Sumerian. These reforms touched all aspects of the management of empire, including mathematics:
“Metrologies were unified to become increasingly interdependent, while numerals were frequently written with incised cuneiform instead of impressed signs.”[1]
The curviform symbols for System S, introduced in Table 2, were first used in the proto-Elamite period (c. 3100BC).[2] They continued to be used for nearly a millennium before being replaced by the cuneiform symbols pictured in Table 11.

In order to see the new System S in action, we turn to AO 5676, pictured in Figure 19. AO 5676 was produced in the city of Umma during the Neo-Sumerian period (c. 2036 BC). It is an accounting of a labor contract between the city and a named manager.[3]

If you look at the first row in the second column, directly underneath the museum reference number has been written, you can see a long string of system S numerals written in cuneiform. This row has been rendered below in Figure 20.[4]
