As is clear from the title, this work includes eighteen articles which apply social networks analysis in their investigation of various aspects of Greco-Roman society in the Mediterranean between the 9th century B.C.E. and the 4th century C.E. The Introduction sets the tone of this volume, first discussing the contributions of Braudel and Goitein to the broad understanding of Mediterranean history and culture. It then continues by briefly reviewing the development of social networks analysis and its application to the fields of archaeology and Roman history. In the first article, “Beyond and Below the Polis: Networks, Associations and the Writing of Greek History”, Kostas Vlassopoulos discusses how social network analysis could be used at both the micro and macro level in the study of ancient Greece. Specifically, he looks at how network analysis could lead to new understanding of relationships within the Greek polis as well as relations between the Greeks and other cultures.
