takes place: while the supra-network of the philosophers appears as a subset of the 'smaller level' networks, the greater network of believers in the Acts of Thomas calls for a radical abandonment of the smaller social networks. We get here a glimpse of an area worthy of further investigation: the interaction between networks. After having thus travelled along literary roads, the reader can move on to real roads, with Y. Lolos's study of the uia Egnatia and of the change that being thus networked brought to the cities it connected. Finally, after an ambitious but rather unstructured detour through Hadrian's Panhellenion, the volume is brought to a close by D. Rathbone's masterful discussion of merchant networks in the Eastern Mediterranean in the fi rst and second centuries A.D., highlighting the role played by networks of different strengths and dimensions (tightly closed ones, wide weak ones, professional ones), formed by publicani, soldiers and veterans, the imperial familia, and banks in the organisation of maritime commerce. 'Networks are everywhere. All we need is an eye for them.' So the Editors in their introduction (p. 7), quoting from A.L. Barabàsi, Linked: the New Science of Networks, (2002), p. 7; and indeed, the studies here collected look at all sorts of networks, with quite different eyes. The challenge is possibly not so much to fi nd networks as to see how they are structured, and even more, how the various networks to which an individual simultaneously belongs interact. For this, the volume under review offers an excellent point of departure.
