Trouble with that is they don't speak in agreement.
One of the historians who lived closest to the Neo-Babylonian period was Berossus, a Babylonian “priest of Bel.” His original work, the Babyloniaca, written about 281 B.C.E., has been lost, and only fragments are preserved in the works of other historians. Berossus claimed that he used “books which had been preserved with great care at Babylon.” Was Berossus really an accurate historian? Consider one example.
Berossus wrote that Assyrian King Sennacherib followed “the reign of [his] brother”; and “after him his son [Esarhaddon ruled for] 8 years; and thereafter Sammuges [Shamashshuma-ukin] 21 years.” (III, 2.1, 4) However, Babylonian historical documents written long before Berossus’ time say that Sennacherib followed his father, Sargon II, not his brother, to the throne; Esarhaddon ruled for 12 years, not 8; and Shamash-shuma-ukin ruled for 20 years, not 21. Scholar R. J. van der Spek, while acknowledging that Berossus consulted the Babylonian chronicles, wrote: “This did not prevent him from making his own additions and interpretations.”2 How do other scholars view Berossus? “In the past Berossus has usually been viewed as a historian,” states S. M. Burstein, who made a thorough study of Berossus’ works. Yet, he concluded: “Considered as such his performance must be pronounced inadequate. Even in its present fragmentary state the Babyloniaca contains a number of surprising errors of simple fact . . . In a historian such flaws would be damning, but then Berossus’ purpose was not historical.”
And what about the other classical historians who, for the most part, based their chronology on the writings of Berossus? Can their historical conclusions really be called reliable?
The Bible is the only reliable yardstick by which these things can be measured.
