 He was regarded as the king of Media at the end of the Neo-Babylonian Empire in the biblical commentaries of John Calvin, Adam Clarke, Keil and Delitzsch, and Lange.In Lange's commentary, Otto Zöckler named Gesenius, Hengestenberg, and other more recent writers who equated Cyaxares II with Daniel's Darius the Mede.These commentaries noted similarities between Cyaxares II as portrayed by Xenophon and what may be inferred about Darius the Mede from the sparse statements about him in the Book of Daniel.
