Concepts such as Social Network Analysis (SNA), spatial mapping, and connectivity offer stimulating new resources for the academic analysis of political, economic, and cultural contacts in historical contexts. Moreover, the great diversity of populations, traditions and religions around the pre-modern Mediterranean provides an ideal, multi-faceted laboratory for the application of these new theories. How did networks of cities, ports, religious centers, colonies, diaspora-communities, diplomats, Grand Tour travellers, or letter-writers contribute to the construction of Mediterranean communities and Mediterranean worlds? What role did the sea itself play in the rise and maintenance of these networks? How and by what means can we best map these networks across the "Blue Web"?
