Royal cult of Sin in Harran ceased after the fall of Assyria, and after the defeat of Aššur-uballiṭ II his temple was looted by Nabopolassar and his Median allies (Ummanmanda). However, royal interest in it was revived later on in the Neo-Babylonian period by Nabonidus. His mother Adad-guppi most likely hailed from this city, and she was either a priestess of Sin or an upper class laywoman particularly devoted to this god. It has been suggested that her personal devotion to the tutelary god of Harran influenced the religious outlook of her son. The rebuilding of Eḫulḫul started during the reign of Nabonidus, but it is not known if the project was complete by the time he was deposed by Cyrus the Great in 539 BCE.
