Although one of the longest lasting in history, the ancient Roman empire had no fixed boundaries. However, Roman armies clearly reached certain points-which today we call frontiers-where they simply stopped advancing and annexing new territories. C. R. Whittaker examines the Roman frontiers both in terms of what they meant to the Romans and in the context of their military, economic, and social function. 55 illustrations | Frontiers of the Roman Empire by C.
