They are deceived, too, by those highly mendacious documents which profess to give the history of many thousand years, though, reckoning by the sacred writings, we find that not 6000 years have yet passed. And, not to spend many words in exposing the baselessness of these documents, in which so many thousands of years are accounted for, nor in proving that their authorities are totally inadequate, let me cite only that letter which Alexander the Great wrote to his mother Olympias, giving her the narrative he had from an Egyptian priest, which he had extracted from their sacred archives, and which gave an account of kingdoms mentioned also by the Greek historians. In this letter of Alexander's a term of upwards of 5000 years is assigned to the kingdom of Assyria; while in the Greek history only 1300 years are reckoned from the reign of Bel himself, whom both Greek and Egyptian agree in counting the first king of Assyria. Then to the empire of the Persians and Macedonians this Egyptian assigned more than 8000 years, counting to the time of Alexander, to whom he was speaking; while among the Greeks, 485 years are assigned to the Macedonians down to the death of Alexander, and to the Persians 233 years, reckoning to the termination of his conquests. Thus these give a much smaller number of years than the Egyptians; and indeed, though multiplied three times, the Greek chronology would still be shorter. For the Egyptians are said to have formerly reckoned only four months to their year; so that one year, according to the fuller and truer computation now in use among them as well as among ourselves, would comprehend three of their old years. But not even thus, as I said, does the Greek history correspond with the Egyptian in its chronology. And therefore the former must receive the greater credit, because it does not exceed the true account of the duration of the world as it is given by our documents, which are truly sacred. Further, if this letter of Alexander, which has become so famous, differs widely in this matter of chronology from the probable credible account, how much less can we believe these documents which, though full of fabulous and fictitious antiquities, they would fain oppose to the authority of our well-known and divine books, which predicted that the whole world would believe them, and which the whole world accordingly has believed; which proved, too, that it had truly narrated past events by its prediction of future events, which have so exactly come to pass!
