Other large rectangular tablets are inscribed with lists of the principal events in different kings’ reigns and are obviously of immense importance for the reconstruction of Babylonian and Assyrian history. One of the tablets belonging to this class (Brit. Mus. No. 92702) gives us a list of the chief events, after which the various years of Sumu-abu, Sumu-la-ilu, Zabum, Apil-Sin, Sin-muballit, Khammurabi and Samsu-iluna, kings of the first dynasty of Babylon (about the end of the third and beginning of the second millennium B.C.) were named. Another of the same class (Brit. Mus. No. 92502) gives us a list of the leading events which took place in Babylonia and Assyria from the third year of Nabonassar, king of Babylon 744 B.C., and the first year of Shamash-shum-ukîn, the contemporary of Ashur-bani-pal (668 B.C.). One of the most interesting events here alluded to is the assassination of Sennacherib by his son on the 20th day of the month Tebet, and in the 23rd year of his reign. Among other historical documents of primary importance, a tablet generally known as “the Synchronous History” must be placed in the first rank. This document is an agreement drawn up about the time of Ashur-bani-pal, and it had as its object the settlement of boundary-disputes between Babylonia and Assyria, while its historical value lies largely in the short notices of the various conflicts and alliances between the two countries from about 1600-800 B.C. One other large rectangular tablet (K. 3751) of exceptional interest alike to the historian and the Biblical student, is the document in which Tiglath-Pileser III, king of Assyria 745-727 B.C., gives us an account of his building operations and conquests, and mentions “Ahaz, King of Judah” as one of his tributary princes. This tablet must have been very large when complete, for what remains of it measures nine inches by seven and a half. The largest tablet in the Kouyunjik collection is not however historical in character, but contains a list of the names and titles of various gods, and in its present fragmentary state measures fifteen inches in length.
