Situated roughly midway between the great cities of the Indus Valley and those of the Mesopotamian plains, Tepe Yahya occupies a special place in our conceptions of relations between these distant territories during the early Bronze Age. Its third-millennium levels, dating from 3000 to 2100 BC, are particularly important. In this definitive study, D. T. Potts describes the stratigraphy, architecture, ceramics, and chronology of the site and presents a full inventory of the small finds. Holly Pittman contributes comprehensive illustrations and a discussion of the seals and sealings, and Philip Kohl provides an analysis of the carved chlorite industry. In a foreword and afterword, project director C. C. Lamberg-Karlovsky tells the story of the archaeological expedition and reflects on the contributions of the Tepe Yahya project.
