The Impact of Transportation on Pottery Industries in Roman Britain

Abstract

Abstract The distribution of Roman pottery depended on the transportation system which moved it. Here we trace developments in these distributions during the Roman period in Britain to document how the transportation system developed and assess its impact on the island’s economy. We created a database with records from 775 excavations at 652 sites, and data on over two million pottery sherds. By analyzing the changing distributions of pottery from production centers, we are able to measure improvements in the Roman transportation system over time. These improvements seem to have been most rapid soon after conquest, with transport costs almost halving in the first century of Roman occupation. As the road network expanded and transportation technology improved and pottery gained access to wider markets, producers’ dominance over their local markets declined as rival products became more accessible, and certain industries dramatically increased their outputs. Production by small industries fell in our Middle and Later Roman periods.
