(7) A chronological tablet in the Babylonian collection of Yale University contains a list of the kings of Larsa. This city was conquered by Hammurapi, of the first dynasty of Babylon, in the 31st year of his reign. The tablet, therefore, counts Hammurapi one of the kings of Larsa, ascribing to him twelve years of rule. The tablet was apparently compiled in the twelfth year of Samsuiluna, Hammurapi’s successor, to whom twelve years are also ascribed. It gives the total length of the dynasty of Larsa as 289 years. That dynasty, accordingly, began its rule in 2358 B. C. (8) In a chronological list of the kings of Ur and Nisin on a tablet in the University Museum, Philadelphia,[11] it is stated that the kings of Ur ruled 117 years and the kings of Nisin 225 years and 6 months. A tablet has now been discovered which shows that the dynasty of Nisin was not overthrown until 2117 or 2116 B. C. Its 225 years, therefore, were all parallel to the time of the dynasty of Larsa. As the dynasty of Nisin rose upon the ruins of the kingdom of Ur, the dates of the kingdom of Ur are, therefore, fixed as 2458-2341 B. C. (9) A chronological tablet published by Scheil in the _Comptes rendus_ of the French Academy for 1911 gives a list of five early dynasties of Babylonia: a dynasty of Opis, one of Kish, one of Agade, and two of Erech. (10) A group of chronological tablets in the University Museum in Philadelphia,[12] which assign several dynasties to each of several well-known Babylonian cities, ascribe to their kings incredibly long reigns. One of these is translated in Part II, Chapter IV. (11) Fragments of a work of Berossos, a Babylonian priest who lived after the time of Alexander the Great, contain a list of Babylonian kings. He based his work on such tablets as those in the University Museum. His statements abound accordingly in incredible numbers. From these tablets it appears that the dynasty of Ur was preceded by the dynasty of Gutium, which ruled for 159 years; the dynasty of Gutium was preceded by a dynasty of Erech for 26 years; that, by a dynasty of Agade for 197 years; that, by one king of Erech, Lugalzaggisi, who ruled 25 years; he was apparently preceded by a dynasty of Kish for 106 years; that, by a dynasty of Opis for 99 years. These figures take us back to 3070 B. C., though the arrangement for the time before Lugalzaggisi is in part conjectural. Four dynasties of what are known to have been historical kings existed before this time, so that we are led to place the beginning of the historical period in Babylonia about 3200 B. C. or earlier.
