The name Sumu-yamutbal, for the exrlanation cf which see the Appendix attached to this article, belongs to that large group of personal names which some scholars call "Amurritett while others prefer the term "East Canaanite't. It is universally agreed, however, that the language cf which they bear witness is West Semitic. Imhis particular name is far from being frequentl. Hence, when we encounter it a number of times within a narrow peried of time, the assumpticn seems justified that the ocurrences refer to one and the same person. The Sumu-yamutbal with whom these pages e concerned lived during the reign of Slniddinam of Larsa which lasted only seven years, the years 177-183 of the dynasty of Larsa corresponding to the years 45-51 of the Babylon l2,znasty. Several cocurrences are found in a series of tags to be dealt with in a separate ar-ticle2 which enunzerate sheep due to certain temples, etc. They all bear the dates of Siniddinam which in Ungnadts article "Datenlisten"3 are designated with the letters (a), (O) and (d); of these (a) anu (d) are the ones that are mcst frequently represented in the group. A few of the tags add after the temples a number of persons, presumably dignitaries, to whom sheep are also due, and two-with the date (d) place Sumu-yamutbal at their head. These two tablets are YS 4974 and UIOM 2019; another tablet from the same year, UIOM 2032, records five rams given to cur Sumu-yamutbal4. Ancther small group of tablets5 enumerates prain due to certain persons. On two out of a total of six, Sumu-yamutbal appears again, this time in the year Sin-iddinam (a).
