This volume offers new cuneiform sources on the political, religious, juridical, and economic history of southern Babylonia in the nineteenth and early eighteenth centuries B.C.E. Among these texts is a 600-lines long document (no. 1) recording in unusual detail the daily routine followed in the temples of the city of Larsa and thus sheds light on the religious practices of the ancient Babylonians. Using this document as its point of departure, the first part of the book examines those practices – the service of the gods and the performance of the clergy. This document is especially important for the history of ancient religion.
