In view of the importance of the question, we have treated in some detail the evidence that has been adduced in favour of the theory, that the later kings of Isin were contemporaneous with the earlier rulers of Babylon. It will have been seen that the difficulties involved by the suggested synchronism between Damik-ilishu and Sin-muballit are too grave to admit of its acceptance, while they entirely disappear on referring the disputed date-formulæ to their natural place in the struggle between Babylon and Larsa. This does not preclude the possibility that the dynasties may have overlapped for a shorter period than ninety-nine years. But in view of the total absence of any information on the point, it is preferable to retain the view that the Babylonian monarchy was not established before the close of the Dynasty of Isin.[45] Whatever troubles may have befallen Isin after Ur-Ninib's family had ceased to reign, there is no doubt that under her last two kings the city's influence was re-established, and that she exercised control over Babylon itself. In the course of the German excavations, a clay cone has been found in the temple E-patutila at Babylon, bearing a votive inscription of Sin-magir, the fifteenth king of Isin; and this was evidently dedicated by him as a votive offering in his character of suzerain of the city.[46] Moreover, in this text he lays claim to the rule of Sumer and Akkad. Akkad, as well as Sumer, was also held by his son Damik-ilishu, who succeeded him upon the throne. For a tablet has been found at Abû Habba, dated in the year in which Damik-ilishu built the wall of Isin,[47] and the date upon a tablet from Nippur commemorates his building of the temple of Shamash, named E-ditar-kalama, which was probably in Babylon.[48] Thus both Sippar and Babylon were subject to the city of Isin under the last of her rulers, who, like his father before him, maintained an effective hold upon the kingdom of Sumer and Akkad.
