Darius the Mede (Dan. v. 31) succeeded Belshazzar as king in Babylon b.c. 538, the date assigned in Dan. ix. 1 to the prophecy of the 70 years. But “Darius the king” in whose 6th year (b.c. 516) the Temple was finished (Ezra vi. 15) was Darius Hystaspis, king of Persia, whom Cyril here confounds with “Darius the Mede.” He also fails to distinguish the rebuilding of the Temple, b.c. 516, from the rebuilding of the City by permission of Artaxerxes Longimanus, b.c. 444 (Nehemiah, ii. 1).
