While cuneiform ritual texts dealing with the initiation of the divine image in ancient Mesopotamia were extensively studied and discussed, the ancient Mesopotamian ritual texts dealing with the restoration of the divine image were hardly investigated. This book aims to fill this gap. It presents two main Akkadian texts, known from previously published and newly identified cuneiform tablets from the first millennium BCE, that deal with the rituals that took place during and after the restoration of the divine image. The book interprets the entire ritual as a mythical descent of the god to the netherworld and back, and the temple workshop, where the restoration takes place, as a representation of the netherworld.
