Once again we have the usual Annals as our main source. Earlier scholars have in general satisfied themselves with the publication and study of the latest edition, sometimes supplemented by more or less full extracts from the others. There are reigns, such as that of Sennacherib, where such procedure results in comparatively little distortion of the history. But in no reign is the distortion of the earlier statements more serious, indeed one can hardly recognize the earlier documents in their later and "corrected" form. Accordingly, in no reign is it more imperative that we should disentangle the various sources and give the proper value to each. When we have discovered which document is our earliest and most authentic source for any given event, we have already solved some of the most stubborn problems in the history of the reign. The various conflicting accounts of the Egyptian campaigns, for example, have caused much trouble, but if we recognize that each is a step in the movement toward increasing the credit the king should receive for them, and trust for our history only the first in date, we have at last placed the history of the reign on a firm basis. Our very earliest document furnishes a beautiful illustration of this principle. It is a detailed narrative of the unimportant Kirbit expedition, which is ascribed to the governor Nur ekalli umu. Cylinder E gives a briefer account and Cylinder F one still shorter. Both vaguely ascribe it to the "governors" but do not attempt to claim it for the king. It remained for Cylinder B, a score of years later, to take the final step, and to inform us that the king in person conducted the expedition. Further, the formal conclusion, which immediately follows the Kirbit expedition in our earliest document, shows that this event, unimportant as it was, was the only one which could be claimed for the "beginning of the reign." This campaign is further fixed by the Babylonian Chronicle to the accession year. Yet later cylinders can place before it no less than two expeditions against Egypt and one against Tyre! Our earliest document alone would be enough to prove that these had been taken over from the reign of his father, even did we not have some of this verified by that father himself. [Footnote: K. 2846; Winckler, AOF. I. 474 ff.] Next in date and therefore in value we are probably to place Cylinder E, a decagon fragment, which contains a somewhat less full account of the Kirbit campaign, and a picturesque narrative of the opening of diplomatic relations with Lydia. Before these events, it placed an account of the Egyptian expedition. Although only a portion is preserved, it is sufficient to show that the "first Egyptian expedition" at least was credited to his father. [Footnote: G. Smith, 34f, 76 f., 82f; K. 3083 is identical for a line each with Cyl. E and F.]
