It is likely that the entire series of names partook of the same character, and that, if we possessed them, their bearing would be found to be, not historic, but mythological.

We may parallel this dynasty of Berosus, where he reckons king's reigns by the cyclical periods of _sosses_ and _ners,_ with Manetho's dynasties of Gods and Demigods in Egypt, where the sum of the years is nearly as great.
It is necessary, then, to discard as unhistorical the names and numbers assigned to his first dynasty by Berosus, and to retain from this part of his scheme nothing but the fact which he lays down of an ancient Chaldaean dynasty having ruled in Babylonia, prior to a conquest, which led to the establishment of a second dynasty, termed by him Median.
The scheme of Berosus then, setting aside his numbers for the first period, is--according to the best extant authorities, as follows:-- Dynasty I.

of ( ?) Chaldaean kings.

( ?) years.
II.

of 8 Median " 234 ( ?) " III.
