name of one of Sennacharib's sons, which can be secured only by assuming a mistake in the Armenian alphabet. It is in Eusebius that we find our most useful information, some of the facts being very real additions to our knowledge. But Berossus was also used by the early Apollodorus Chronicle, some time after 144 B. C., from which some of his information may have drifted into other chronological writings. Alexander Polyhistor was used by Josephus, and Abydenus by Cyrillus, Syncellus, and the Armenian historian, the pseudo Moses of Chorene. So in these too, or even in others not here named, may lurk stray trifles from the work of Berossus. Perhaps from this, or from a similar source, comes the Babylonian part of the list of Kings known as the Canon of Ptolemy, which begins, as does the Babylonian Chronicle, with the accession of Nabonassar. [Footnote: The most convenient edition Wachsmuth, _Einleitung in das Studium der alten Geschichte_, 304 ff.; cf. Rogers, 239.] Though directly of Egyptian origin, as is shown by the system of dating, it undoubtedly goes back to a first class Babylonian source, as do the astronomical data in the Almagest of the same author, though here too the Egyptian calendar is used. [Footnote: Cf. Olmstead, _Sargon_, 34 f.] Summing up, practically all the authentic knowledge that the classical world has of the Assyrians and Babylonians came from Berossus. [Footnote: Of the literature on Berossus, we may quote here only Müller, _Fragmenta Historicorum Graecorum_, II. 495 ff.; and the various articles by Schwartz, on Abydenus, Alexandros 88, and Berossus, in the Pauly-Wissowa _Real-encyclopädie_.] Herodotus may furnish a bit and something may be secured from the fragments of the Assyriaca of Ctesias, but it is necessary to test each fact from other sources before it can be accepted.
