Gathering data from the Greek world and the Roman world, this book aims to contribute to a better analysis of local and regional economic circuits in the Mediterranean, and puts therefore the issues of storage, distribution methods and speculation at the heart of the debate. By focusing on storage places and buildings, this survey is also a study of circuits and flows, addressed both in the written and archaeological documentation. Several examples show the pragmatism and multi-functionality of buildings, the links between the role of the State and the action of individuals, the complexity of circuits. Our knowledge of the organization of exchanges is enriched here by numerous case studies that testify to construction techniques and space arrangements in storage buildings but also to social and economic interest networks based on professional groups. This study leads to a re-examination of the forms of economic integration in the Mediterranean, from the classical period to the Empire.
