countries, bestowed upon Lugalzaggisi the kingdom of the world, and granted unto him success in the sight of the world, when he filled the lands with his power, and conquered them from the rising of the sun unto the setting of the same, at that time he made straight his path from the Lower Sea of the Tigris and Euphrates unto the Upper Sea, and he granted him dominion over all from the rising of the sun unto the setting of the same, so that he caused the lands to dwell in peace.” Now when first the text of this inscription was published there existed only vague indications of the date to be assigned to Lugalzaggisi and the kingdom that he founded. It was clear from the titles which he bore, that, though Gishkhu was his native place, he had extended his authority far beyond that city and had chosen Erech as his capital. Moreover, he claimed an empire extending from “the Lower Sea of the Tigris and Euphrates unto the Upper Sea.” There is no doubt that the Lower Sea here mentioned is the Persian Gulf, and it has been suggested that the Upper Sea may be taken to be the Mediterranean, though it may possibly have been Lake Van or Lake Urmi. But whichever of these views might be adopted, it was clear that Lugalzaggisi was a great conqueror, and had achieved the right to assume the high-sounding title of lugal halama, “king of the world.” In these circumstances it was of the first importance for the study of primitive Chaldæan history and chronology to ascertain approximately the period at which Lugalzaggisi reigned.
