How useful is the concept of "network" for historical studies and the ancient world in particular? Using theoretical models of social network analysis, this book illuminates aspects of the economic, social, religious, and political history of the ancient Greek and Roman worlds. Bringing together some of the most active and prominent researchers in ancient history, this book moves beyond political institutions, ethnic, and geographical boundaries in order to observe the ancient Mediterranean through a perspective of network interaction. It employs a wide range of approaches, and to examine relationships and interactions among various social entities in the Mediterranean. Chronologically, the book extends from the early Iron Age to the late Antique world, covering the Mediterranean between Antioch in the east to Massalia (Marseilles) in the west. This book was published as two special issues in Mediterranean Historical Review.
