14 TSŠ 50: Conclusion

We saw in Activity 15 that 1 silo is equal to 4 géš’u gur. While TSŠ 50 may simply be an account of how many men can be paid with 1 silo of barley, most Assyriologists agree that it is more likely the solution to the following metrological-mathematical question.

Question: if 1 silo of 4 géš’u gur is used to pay men a wage of 7 sìla of barley each, how many men can be paid?

The solution to this question is to divide 4 géš’u gur by 7 sìla. While TSŠ 50 gives the correct answer, it gives no hint as to how the problem was solved.  Friberg suggests that the method employed by the Sumerian scribe was likely very similar to the one used in Ebla described in Chapter 12.[1]

In order to apply the Eblaite method to answer this question, we must first identify the steps a Sumerian would have used. There are two important differences between Ebla and Sumer in this regard. First, the two had distinct metrologies for grain capacity. And Second, Sumer used System S rather than System D. Table ? describes the Sumerian system for capacity, which Assyriologists shorten to System C.

Table 9. The Sumerian System C.
Symbol Transliteration Relative Value
The cuneiform symbol for "gín." gín 1/60 sìla
The proto-cuneiform symbols for "sìla." sìla 1 sìla
The cuneiform for the word "bàn." bàn 10 sìla
The cuneiform for the word "ba."The cuneiform symbol for the Eblaite word "ri."The cuneiform for the word "ga." barig 6 bàn
The cuneiform for the word "gur." gur  8 barig
With System C in hand, Activity 16[2] takes us through the steps a Sumerian scribe would like take to answer the question phrased at the start of this chapter.

Activity 16. Refer to Table 9 and Table 2 in order to answer the following question.

Divide 4 géš’u gur by 7 sìla by filling in the following table following the Eblaite method discussed in Chapter 12. Write your solution using System S.[3]

  2. The table in Activity 16 is based on the explanation found in Friberg (2007) 415.
  3. Technically barley rations would be enumerated using a different system, called System B for "bisexagesimal," but the system agreed with System S for numerals less than 2 géš . In our case there will never be more than 7 sìla remaining. For an example of System B in use, read Jören Friberg, "Three thousand years of sexagesimal numbers in Mesopotamian mathematical texts.''
