From the brief summary given in the preceding paragraphs it will have been noted that we have recovered the names of some twelve patesis of Lagash, who may be assigned to the period between the dynasties of Akkad and Ur. Of these twelve names no less than eleven occur upon a group of tablets, which were found together at Tello, and are marked out by their shape and contents as belonging to a single period. The tablets themselves are of unbaked clay, and they form a transition between the types of Akkad and Ur. In the last of the reigns mentioned it is probable that we may trace a synchronism with the Dynasty of Ur, and, although no actual point of contact can yet be established with the Dynasty of Akkad, such evidence as that furnished by Ug-me's sealing suggests that no considerable lapse of time can have taken place. That these twelve patesis were the only ones who ruled at Lagash during this interval is improbable, and at any time the names of other rulers may be recovered. But it is certain the reigns of many of these patesis were extremely brief, and that we have not to do with a single dynasty, firmly established throughout the whole period, whose separate members, after their accession, each held the throne for the term of his natural life. We have definite proof that several of the patesis, such as Ka-azag, Galu-Bau, and Galu-Gula, ruled only for a few years, and it would seem that at certain points during this period a change of rulers took place in Lagash with considerable frequency.
