For the most part, the study of large-scale trade and exchange in the ancient world remains distanced from the physical hardships of real human travel. Ancient trade or, more neutrally, ancient ‘interaction’ is often discussed as if it took place between actors who inhabited a flat and unchanging spatial surface. In fact, topography, climate and seasonality are essential to understanding the changing forms and intensity of human travel that enabled ‘interdependence’ between communities of the Near East. This paper demonstrates some of the steps needed to reintegrate seasonality with the study of ancient trade.

The areas that were occupied by early farmers and town-dwellers were often very different from the landscapes that can be seen in the same areas today. Some of the most important changes took place in the great river basins where urban civilisation first emerged. Southern Mesopotamia (Iraq), the land of the two rivers, has been transformed over the last six thousand years by the changing relationships between rivers, land and sea. Although the pattern has not yet been reconstructed in detail, satellite imagery can be used to outline the major processes of change, and to visualise what an extraordinary landscape this was at the time of the first cities.
