For the remaining reigns of the dynasty, we have only the data in the Assyrian Chronicle. No annals or in fact any other inscription has come down to us, and, so far at least as the annals are concerned, there is little likelihood of their discovery, as there is no reason to believe that any were composed in this period of complete decline. But, curiously enough, from this very period comes the document which throws the most light on the earliest period of Assyrian expansion, the so called Synchronistic history. [Footnote: II R. 65, 1; III R. 4, 3; Winckler, _Untersuch_., 148 ff.; CT. XXXVI. 38 ff.; cf. the introduction of Budge-King; King, _Tukulti Ninib._ Peiser-Winckler, KB. I. 194 ff.; G. Smith, _Disc_. 250 f.; Sayce, TSBA. II. 119 ff.; RP¹, III. 29 ff.; RP², IV. 24 ff.; Barta In Harper, 195; cf. Winckler, AOF. I. 114 ff.; Belck, _Bettr. Geog. Gesch._, I. 5 ff.] Adad nirari is the last ruler mentioned, but the fact that he is named in the third person shows that it was compiled not earlier than the reign of his successor Shalmaneser IV. Our present copy is a tablet from the library of a later king, seemingly Ashur bani apal. [Footnote: Maspero, _Hist_., II. 595, dates its composition to this reign.] In form, it marks an advance over any historical document we have thus far studied, for it is an actual history for many centuries of the relations between Assyria and Babylonia. But it is as dry as possible, for only the barest facts are given, with none of the mass of picturesque details which we have learned to expect in the annals of the individual kings. Nevertheless, its advance over preceding documents should not be over estimated. Its emphasis on treaties and boundaries has led to the idea that it was compiled from the archives as a sort of diplomatic pièce justificative in a controversy with Babylonia over the possession of a definite territory. [Footnote: Peiser-Winckler, KB. I. 194 n. 1.] Its true character, however, is clearly brought out in its closing words "A succeeding prince whom they shall establish in the land of Akkad, victory and conquest may he write down, and on this inscribed stone (naru), eternal and not to be forgotten, may he [add it]. Whoever takes it, may he listen to all that is written, the majesty of the land of Ashur may he worship continually. As for Shumer and Akkad, their sins may he expose to all the regions of the world." [Footnote: IV. 32 ff.]
