The Religion of Babylonia and Assyria
“ Nebuchadnezzar, so devoted to Marduk and Nabu, appears to have regarded E-Kur as a serious rival to E-Sagila and E-Zida. Some traces of building operations at E-Kur appear to date from the Persian period, but, practically, the history of E-Kur comes to an end at the close of the seventh century. The sanctity of the place, however, remained; a portion of the old city becomes a favorite burial site, while other parts continue to be inhabited till the twelfth century of our era. ”
