In Old Iran the Sacred Fire was kept perpetually alight. Sweet perfumes were spread around the place of prayer, for which a little eminence was chosen, but there were no images and no temples. Archæologists have failed to find traces of a building set apart for religious worship among the splendid ruins of Persepolis: the “forty towers” only tell of the pleasure-palace of an Eastern king. Was it that the profound spirituality of this people shrank not only from carving a graven image of the deity, but also from giving him a house made with hands? What could the maker of the firmament want with human fanes? Some such thought may have caused the Iranians to suppress for so long a time the instinct which impels man to build temples. In any case, it seems as if Cyrus and after him Darius threw themselves into the scheme for rebuilding the Hebrew temple with all the more enthusiasm from the fact that immemorial custom held them back from temple-building at home. The cuneiform inscriptions bear witness that these kings were monotheists: they believed in one sole creator of heaven and earth, by whose will kings reign and govern, and if they invoked the aid of heavenly hierarchs they never confused the creatures, however powerful, with the creator. That Creator they called by the name of Ahura Mazda, but they recognised that he was one, whatever the name might be by which he was called. “Thus saith Cyrus, king of Persia: the Lord God of Heaven hath given me all the kingdoms of the earth, and He hath charged me to build Him a house at Jerusalem, which is Judah.” In the uncanonical Book of Esdras, it is said more significantly that King Cyrus “commanded to have the house of the Lord in Jerusalem built where they should worship with eternal fire.” The recently deciphered Babylonian inscriptions have been brought forward to show that the Jews were mistaken in thinking that Cyrus was a monotheist, because he honoured Merodach in Babylon just as he had honoured Jehovah at Jerusalem. He was, it is said, a “polytheist at heart.” If he was, his honouring Merodach does not prove it. To my mind it proves exactly the reverse. Cyrus understood the monotheism which was at the bottom of the Babylonian religious system and which these very tablets have revealed to modern scholarship. He understood that “however numerous and diversified the nations of the earth may be, the God who reigns over them all can never be more than one.”[2]
