This policy of fixing the boundary by arbitration seems to have been successful, and to have secured peace between Shirpurla and Gishkhu for some generations. But after a period which cannot be accurately determined a certain patesi of Gishkhu, named Ush, was filled with ambition to extend his territory at the expense of Shirpurla. He therefore removed the stele which Mesilim had set up, and, invading the plain of Shirpurla, succeeded in conquering and holding a district named Gu-edin. But Ush’s successful raid was not of any permanent benefit to his city, for he was in his turn defeated by the forces of Shirpurla, and his successor upon the throne, a patesi named Enakalli, abandoned a policy of aggression, and concluded with Eannadu, patesi of Shirpurla, a solemn treaty concerning the boundary between their realms, the text of which has been preserved to us upon the famous Stele of Vultures in the Louvre.[3] [3] A fragment of this stele is also preserved in the British Museum. It is published in Cuneiform Texts in the British Museum, Pt. vii. According to this treaty Gu-edin was restored to Shirpurla, and a deep ditch was dug between the two territories which should permanently indicate the line of demarcation. The stele of Mesilim was restored to its place, and a second stele was inscribed and set up as a memorial of the new treaty. Enakalli did not negotiate the treaty on equal terms with Eannadu, for he only secured its ratification by consenting to pay heavy tribute in grain for the supply of the great temples of Nin-girsu and Ninâ in Shirpurla. It would appear that under Eannadu the power and influence of Shirpurla were extended over the whole of Southern Babylonia, and reached even to the borders of Elam. At any rate, it is clear that during his lifetime the city of Gishkhu was content to remain in a state of subjection to its more powerful neighbour. But it was always ready to seize any opportunity of asserting itself and of attempting to regain its independence.
