The Camel and Fowey rivers incise deeply into Cornwall, nearly meeting in the middle. This book is a landscape study of the Camel/Fowey corridor which forms a natural trans-peninsular portage route across Cornwall, avoiding circumnavigating the notoriously hazardous Land's End sea route. The author investigates the effect this route had on society through micro- and macro settlement studies involving an extensive programme of geophysical analysis. This has generated fresh insight into the socio-economic and continuity dynamics of this part of Cornwall, together with the interaction between Romans and the indigenous population. The findings explore socio-political influences in the Roman period and cultural continuity into the post-Roman period.
