In this second lecture extracted from Sayce's Origin and Growth of Religion, the renowned Assyriologist specifically considers the Babylonian deity Bel-Merodach. Noting that Cyrus the Great was a worshipper of this deity, the outlook of the priesthood of Bel-Merodach regarding his conquest of Babylon begins the discussion. Sayce then discusses localized versions of Merodach, considering Eridu, Borsippa, and Assur.
