Networks are not objective historical entities, but rather a means for the analysis of historical data. As such, they constitute a powerful but easily misused tool. In deploying network theory to analyze seaborne mobility in the ancient Mediterranean, contributors to the conference volume Maritime Networks in the Ancient Mediterranean World, edited by Justin Leidwanger and Carl Knappett, are all too aware of this problem. The avowed aim of the volume is to “push forward the study of Mediterranean maritime interaction through explicit and accessible network approaches, which may be more or less mathematical, but are all ‘models’ in a basic sense and hence intellectually helpful if inevitably reductive” (p. 13). Overall, the eight conference papers, preceded by an introduction and followed by a conclusion, make good on this promise. The book represents a discourse on method in the fields of Mediterranean archaeology and ancient history, showcasing network theory. And it will surely find many readers among archaeologists and historians, whether they are looking to enter the realm of network theory or to improve their current use of these methods.
