In this volume, papers by leading Roman historians and archaeologists discuss trade within the Roman Empire and beyond its frontiers between c.100 BC and AD 350, and the role of the state in shaping the institutional framework for trade. Documentary, historical, and archaeological evidence forms the basis of a novel interdisciplinary approach. Like its predecessors from OxREP, this volume contains a wealth of valuable interventions in debates about the Roman economy. The synthesis of recently discovered or compiled archaeological material, often by scholars responsible for its initial production, makes this book invaluable to economic historians. The inclusion of materials that are usually marginalized and the insistence on the importance of extra-imperial trade are themselves important steps forward as well. Any collection of scholarship on the Roman economy should contain this book.
