Within the limits of Sumer and Akkad Narâm-Sin appears to have followed his father's policy of materially benefiting the provincial cities, while keeping their administration under his immediate control. Thus he continued the service of convoys, and at the same time devoted himself to the erection of temples to the gods. His rebuilding of the temples of Enlil at Nippur and of Shamash at Sippar has been already referred to, while his votive onyx vases found at Tello[71] prove that he did not neglect the shrines of Lagash. Another Sumerian city in which he undertook building operations was Ninni-esh, for there he rebuilt the temple dedicated to the goddess Ninni in the same year that he laid the foundation of the temple at Nippur.[72] But by far the most interesting of his building records is the stele sculptured with the figure of himself,[73] which is usually known as the Diarbekr stele. When first brought to the Museum at Constantinople it was said to have been found at Mardin,[74] and later on, certainly with greater accuracy, to have come from Diarbekr.[75] As a matter of fact, it was discovered at Pir Hussein, a small village built beside a low tell, and situated about four and a half hours to the N.N.E. of Diarbekr, on the Ambar Su, a stream which rises in the lower slopes of the Taurus, and, after running parallel to the Sebene Su, joins the Tigris below Diarbekr. It was found by the villagers some nineteen years ago when they were digging for building materials [Illustration: Fig. 59.--Stele sculptured with the figure of Narâm-Sin, King of Akkad, which was found at Pir Hussein near Diarbekr. In the Imperial Ottoman Museum.] on the site of the ancient city below the tell.[76] There is no doubt that the stele was found in situ,[77] and it furnishes remarkable evidence of the extent of Narâm-Sin's influence northwards. The inscription upon the stone is broken, but it contains a reference to the defeat of the king's enemies by the god Enki, or Ea, within the four quarters of the world. That Narâm-Sin and his army should have penetrated to the upper reaches of the Tigris is remarkable enough in itself, but that he should have erected a stele of victory, and possibly a building, in at least one of the towns he subdued during the campaign, suggests that his occupation of this region was effective for some time.
