The Babylonian dynasties of Berossus are incomplete. The authors solve for the missing values in Berossus using known information. As a result, we find dates for Ninyas, the Fall of Akkad to the Guti, Sardanapalus, and the first and second Median Revolts in the days of Ashur-danin-pal and Sargon II. We also find clarifying information about the reign and identity of Semiramis II as a contemporary of Tukulti Ninurta I. Finally, we identify three of the "god-kings" common to the histories of the ancient nations, as real people in the king lists. The resulting table of Berossus covers the era from the Flood to the conquest of Babylon by Cyrus, in 1,809 years.
