A long obscure passage precedes a very detailed account of the expedition to Babylon and Kar-Duniyas against Merodach-baladan, recorded under the first year of the annals on the Kouyunjik bulls.[95] After mentioning some canals which he had made in the south of Assyria, Sennacherib speaks of the army which defended the workmen being attacked by the king of Elam and the king of Babylon, with many kings of the hills and the plains who were their allies. He defeated them in the neighbourhood of Khalul (site undetermined). Many of the great people of the king of Elam and the son of the king of Kar-Duniyas were either killed or taken prisoners, while the kings themselves fled to their respective countries. Sennacherib then mentions his advance to Babylon, his conquest and plunder of it, and concludes with saying, that he brought back from that city the images of the gods which had been taken by _Merodach-adakhe_ (?), the king of Mesopotamia, from Assyria 418 years before, and put them in their places. Now, the importance of this inscription, presuming it to be correctly interpreted, will at once be perceived, for it proves almost beyond a doubt, that at that remote period the Assyrians kept an exact computation of time. We may consequently hope that sooner or later chronological tables may be discovered, which will furnish us with minute and accurate information as to the precise epoch of the occurrence of various important events in Assyrian history. It is, indeed, remarkable that Sennacherib should mark so exactly the year of the carrying away of the Assyrian gods. This very date enables us, as will hereafter be seen, to restore much of the chronology, and to place, almost with certainty, in the dynastic lists, a king whose position was before unknown. We find also that the greater part, if not the whole, of the rock-sculptures were executed either at the end of the first, or at the beginning of the second, year of the reign of Sennacherib. As he particularly describes six tablets, it is probable that the others were added at some future period, and after some fresh victory. When the whole inscription is restored, we shall probably obtain many other important details which are wanting in the annals of Kouyunjik, and in the records of the same period.
