Trading connections and routes play a very important part in the development (or re-development) of urban centres in the Middle Bronze Age Levant. This is particularly clear in the regions of Cilicia and the Amuq Plain in the Hatay, in the north-east corner of the East Mediterranean, where at the beginning of the Middle Bronze Age we have evidence of large-scale public buildings and fortification systems which represent the revival of complex political and economic structures, following a collapse at the end of the Early Bronze Age. A key role in this is played by harbour towns on the Cilician and Levantine coasts, which have an important part in the articulation and exploitation of maritime and inland routes connecting different zones and their resources. This in turn leads, by the beginning of the Late Bronze Age, to the formation of a symbiotic network of semi-dependent kingdoms which link these different inland and coastal zones in a single interactive socio-economic system.

This visual essay explores the possibility of delineating two different types of routes, 'pathways' and 'highways', and the extent to which archaeology can help to analyse them. The technologies of cost-raster GIS analysis are introduced and applied to two case studies in Eastern Anatolia and Western Central Asia, c. 3000-1000 BC. It is to be hoped that the highlighted patterns, combined with a knowledge of contemporary material transformations, will provide insights into the processes of socio-economic change across these reconstructed networks of interaction.
