Before taking up a more detailed study of these questions, it is necessary to secure a general view of the situation we must face. The types of inscriptions, especially in the later days of the empire, are numerous. In addition to the brick and slab inscriptions, rarely of value in this later period, we have numerous examples on a larger scale of the so called "Display" inscriptions. They are usually on slabs of stone and are intended for architectural adornment. In some cases, we have clay tablets with the original drafts prepared for the workmen. Still others are on clay prisms or cylinders. These latter do not differ in form from many actual annals, but this likeness in form should not blind us to the fact that their text is radically different in character. All the display inscriptions are primarily of architectural character, whether intended to face the walls of the palace or to be deposited as a sort of corner stone under the gates or at the corners of the wall. We should not expect their value to be high, and indeed they are of but little worth when the corresponding annals on which they are based has been preserved. For example, we have four different recensions of a very long display inscription, as well as literally scores of minor ones, also of a display character, from the later years of Sargon. The minor inscriptions are merely more or less full abstracts of the greater and offer absolutely nothing new. The long display inscription might be equally well disregarded, had not the edition of the annals on which it is based come down to us in fragmentary condition. We may thus use the Display inscription to fill gaps in the Annals, but it has not the slightest authority when it disagrees with its original. It is true that for many reigns, even at a fairly late date, the display inscriptions are of great value. For the very important reign of Adad nirari (812-785 B.C.), it is our only recourse as the annals which we may postulate for such a period of development are totally lost. The deliberate destruction of the greater portion of the annals of Tiglath Pileser IV forces us to study the display documents in greater detail and the loss of all but a fragment of the annals of Esarhaddon makes for this period, too, a fuller discussion of the display inscriptions than would be otherwise necessary. In addition, we may note that there are a few inscriptions from other reigns, for example, the Nimrud inscription of Sargon, which are seemingly based on an earlier edition of the annals than that which has come down to us and which therefore do give us a few new facts.
