When the German excavations were begun at Ashur, the earliest capital of the Assyrian empire, it was hoped that the scanty data with which we were forced to content ourselves in writing the early history would soon be much amplified. In part, our expectations have been gratified. We now know the names of many new rulers and the number of new inscriptions has been enormously increased. But not a single annals inscription from this earlier period has been discovered, and it is now becoming clear that such documents are not to be expected. Only the so-called "Display" inscriptions, and those with the scantiest content, have been found, and it is not probable that any will be hereafter discovered. It was not until the end of the fourteenth century B. C. with the reign of Arik den ilu, that we have the appearance of actual annalistic inscriptions. That we are at the very beginning of annalistic writing is clear, even from the fragmentary remains. The work is in annals form, in so far as the events of the various years are separated by lines, but it is hardly more than a list of places captured and of booty taken, strung together by a few formulae. [Footnote: Scheil, OLZ. VII. 216. Now in the Morgan collection, Johns, _Cuneiform Inscriptions_, 33.] With this one exception, we do not have a strictly historical document nor do we have any source problem worthy of our study until the time of Tiglath Pileser I, about 1100 B.C. To be sure, we have a good plenty of inscriptions before this time, [Footnote: L. Messerschmidt, _Keilschrifttexte aus Assur_. I. Berlin 1911; _Mittheilungen der Deutschen Orient Gesellschaft_; cf, D. D. Luckenbill, AJSL. XXVIII. 153 ff.] and the problems they present are serious enough, but they are not of the sort that can be solved by source study. Accordingly, we shall begin our detailed study with the inscriptions from this reign. Then, after a gap in our knowledge, caused by the temporary decline of Assyrian power, we shall take up the many problems presented by the numerous inscriptions of Ashur nasir apal (885-860 B.C.) and of his son Shalmaneser III (860-825 B.C.). In the case of the latter, especially, we shall see how a proper evaluation of the documents secures a proper appreciation of the events in the reign. With these we shall discuss their less important successors until the downfall of the dynasty. The revival of Assyrian power under Tiglath Pileser IV (745-728 B.C.) means a revival of history writing and our problems begin again. The Sargonidae, the most important of the various Assyrian dynasties, comprising Sargon (722-705 B.C.), Sennacherib (705-686 B.C.), Esarhaddon (686-668 B.C.), and Ashur bani apal (668-626 B.C.), furnish us a most embarrassing wealth of historical material, while the problems, especially as to priority of date and as to consequent authority, become most complicated.
