Now, putting aside authors who merely re-echo the statements of others, there seem to be, in the present case, two and two only distinct original authorities--Herodotus and Ctesias. Of these two, Herodotus is the earlier. He writes within two centuries of the termination of the Assyrian rule, whereas Ctesias writes at least thirty years later. He is of unimpeachable honesty, and may be thoroughly trusted to have reported only what he had heard. He had travelled in the East, and had done his best to obtain accurate information upon Oriental matters, consulting on the subject, among others, the Chaldaeans of Babylon. He had, moreover, taken special pains to inform himself upon all that related to Assyria, which he designed to make the subject of an elaborate work distinct from his general history. Ctesias, like Herodotus, had had the advantage of visiting the East. It may be argued that he possessed even better opportunities than the earlier writer for becoming acquainted with the views which the Orientals entertained of their own past. Herodotus probably devoted but a few months, or at most a year or two, to his Oriental travels; Ctesias passed seventeen years at the Court of Persia. Herodotus was merely an ordinary traveller, and had no peculiar facilities for acquiring information in the East; Ctesias was court-physician to Artaxerxes Mnemon, and was thus likely to gain access to any archives which the Persian kings might have in their keeping. But these advantages seem to have been more than neutralized by the temper and spirit of the man. He commenced his work with the broad assertion that Herodotus was “a liar,” and was therefore bound to differ from him when he treated of the same periods or nations. He does differ from him, and also from Thucydides, whenever they handle the same transactions; but in scarcely a single instance where he differs from either writer does his narrative seem to be worthy of credit. The cuneiform monuments, while they generally confirm Herodotus, contradict Ctesias perpetually. He is at variance with Manetho on Egyptian, with Ptolemy on Babylonian, chronology. No independent writer confirms him on any important point. His Oriental history is quite incompatible with the narrative of Scripture. On every ground, the judgment of Aristotle, of Plutarch, of Arrian, of Scaliger, and of almost all the best critics of modern times, with respect to the credibility of Ctesias, is to be maintained, and his authority is to be regarded as of the very slightest value in determining any controverted matter.
