This is the final installment in a tripartite critical edition of the inscriptions of the last major Neo-Assyrian king, Ashurbanipal, and the members of his family. The Royal Inscriptions of the Neo-Assyrian Period 5/3 provides reliable, up-to-date editions and English translations of 106 historical inscriptions written in the Akkadian and Sumerian languages. These inscriptions account for all certainly identifiable and positively attributable inscriptions of Ashurbanipal discovered in Babylonia, in the East Tigris Region, and outside of the Assyrian Empire, together with inscriptions of some members of Ashurbanipal’s family—his wife Libbali-šarrat, as well as his sons and successors Aššur-etel-ilani and Sîn-šarra-iškun—and loyal officials. Each text edition is accompanied by an English translation, brief introduction, catalogue of exemplars, commentary, and bibliography. In addition to a critical introduction to the sources, RINAP 5/3 also includes relevant studies of various aspects of Ashurbanipal’s reign and the final years of the Assyrian Empire; translations of the “Chronicle Concerning the Early Years of Nabopolassar” and the “Fall of Nineveh Chronicle”; photographs of objects inscribed with texts of Ashurbanipal, Aššur-etel-ilani, and Sîn-šarra-iškun; indexes of museum and excavation numbers and selected publications; and indexes of proper names. Expertly prepared by three leading philologists, this eagerly awaited work will be a key reference for Assyriologists, Near Eastern historians, biblical scholars, and scholars of ancient languages for decades to come.
