[245] When Daniel had told the king that the writing upon the wall signified these events, Baltasar was in great sorrow and affliction, as was to be expected, when the interpretation was so heavy upon him. However, he did not refuse what he had promised Daniel, although he were become a foreteller of misfortunes to him, but bestowed it all upon him; as reasoning thus, that what he was to reward was peculiar to himself, and to fate, and did not belong to the prophet, but that it was the part of a good and a just man to give what he had promised, although the events were of a melancholy nature. Accordingly, the king determined so to do. Now, after a little while, both himself and the city were taken by Cyrus, the king of Persia, who fought against him; for it was Baltasar, under whom Babylon was taken, when he had reigned seventeen years. And this is the end of the posterity of king Nebuchadnezzar, as history informs us; but when Babylon was taken by Darius, and when he, with his kinsman Cyrus, had put an end to the dominion of the Babylonians, he was sixty-two years old. He was the son of Astyages, and had another name among the Greeks. Moreover, he took Daniel the prophet, and carried him with him into Media, and honored him very greatly, and kept him with him; for he was one of the three presidents whom he set over his three hundred and sixty provinces, for into so many did Darius part them.
