It was probably after his successful return from the long expedition in the north-west that Lugal-zaggisi deposited his vases as votive offerings within Enlil's shrine at Nippur, and engraved upon them the inscriptions from which we obtain our information concerning his reign. In the third column of his text he states that he has dedicated them to Enlil, after having made due offerings of loaves in Nippur and having poured out pure water as a libation. He then adds a prayer of dedication, in which he prays for life for himself, and peace for his land, and a large army. "May Enlil, the king of the lands," he says, "pronounce my prayer to Ana, his beloved father! To my life may he add life! May he cause the lands to dwell in security! Warriors as numerous as the grass may he grant me in abundance! Of the celestial folds may he take care! May he look with kindness on the land (of Sumer)! May the gods not alter the good destiny they have assigned to me! May I always be the shepherd, who leads (his flock)!"[10] We may regard it as typical of the great conqueror that he should pray for a supply of warriors "as numerous as the grass." It is fortunate for our knowledge of early Sumerian history that the shrine of Enlil at Nippur should have been the depository for votive offerings, brought thither by the rulers of city-states to commemorate their victories. Of the inscribed objects of this class that were recovered at Nippur during the American excavations on that site, by far the most important are the vase-fragments of Lugal-zaggisi, which have already been described. But others were found, which, though supplying less detailed information, are of considerable value, since they furnish the names of other rulers of Sumer, who may probably be grouped with Lugal-zaggisi. Two kings of this period are Lugal-kigub-nidudu and Lugal-kisalsi, each of whom bore the title "King of Erech" and "King of Ur," while the former, like Lugal-zaggisi, styles himself in addition "king of the land," _i.e._ of Sumer. Their inscriptions were found in the mound of Nippur at about the same level as the vase-fragments of Lugal-zaggisi, and a comparison of the characters employed in each set of texts suggests that they date from about the same period.
