 In their view, the difference in name could be explained by the fact that kings at that time—including Artaxerxes I, Darius II, Artaxerxes III, Darius III—had a throne name in addition to their personal name.In the case of Cyaxares II, Harpocration and Berossus were cited as evidence showing that the throne name of Cyaxares II was Darius.Regarding correlations between Cyaxares and Darius the Mede, Zöckler wrote, "the account given by Xenophon regarding Cyaxares so fully agrees with the narrative of Daniel regarding Darius the Mede, that, as Hitzig confesses, 'the identity of the two is beyond a doubt.'"
