Who was Darius the Mede?

In contrast to the opinion of Jehovah’s Witnesses, Daniel was not a contemporary witness at the court of Persian rulers. His historical knowledge is poor. For example, he confuses “Darius the Mede” (Darius I) with Cyrus II. Daniel’s book, chapter 6, is a legend. Its unknown author uses the true career of Ugbaru II, also known as Gobrias II, a governor of Babylon, as a blueprint for his leading actor Daniel.
