This book contains a selection of nineteen articles published by K.R. Veenhof, focusing on his main field of study: law and trade in the Old Babylonian and Old Assyrian society of the early second millennium B.C. They were originally published in journals, conference proceedings and collective volumes over the past fifty years. Their reissue here is motivated by their lasting value and their fundamental importance to the study of these subjects.It includes both "broad" articles, which give an introduction to or an overview of a specific subject, e.g. Old Assyrian trade and the practice of justice in Babylonia in the early second millennium B.C., and "narrow" ones that give an in-depth study of a single issue or a single text, such as a problematic paragraph of Hammurabi's law code or the meaning of the noun iṣurtum. The first two articles provide a general introduction to the subject; the next nine focus on Old Assyrian society, and the final eight concern Old Babylonian.The inclusion of "broad" and "narrow" articles makes this publication of interest both to the well-informed general reader interested in the Ancient Near East and to the specialist working on Old Babylonian and Old Assyrian society.Prof. dr. Klaas R. Veenhof (1935) was a teacher at the Catholic University of Nijmegen, professor at the Free University of Amsterdam and from 1982 until his retirement in 2000 professor at the University of Leiden.
