This new volume presents facsimile copies of over two hundred previously unpublished Babylonian letters and documents written in cuneiform script. The texts, dating from the sixth century B.C., mainly originate from the archives of the Eanna temple in Uruk in southern Mesopotamia, and they contribute important information relating to the political, social, and economic history of this period. In a detailed introduction the authors discuss the significance of these texts and explore their historical and socioeconomic implications. The volume also includes summaries of the contents of the individual documents and comprehensive indices to facilitate full access to the primary data for students and scholars.
