Pierre Salama is famous for the book he wrote at the beginning of his career, Le reseau routier de l'Afrique romaine (The road network in Roman Africa) published in 1951. It had a 1:1.500,000 fold out map prepared by the Algerian cartographic service, without relief or physical details, and with a simple index of sites shown on the map (giving their modern equivalence for the period). Despite the schematic nature of the map, it has been in universal use ever since. However, much new knowledge has been acquired about Roman mapping and the modern names are no longer appropriate. On the initiative of C. Lepelley, N. Duval joined with French and Tunisian African specialists to add to and publish this map, this time as a much more detailed physical map, extended to cover the whole of the Roman province, including Eastern Algeria and Tripolitania. The book starts with a comprehensive introduction to Roman map sources and the methods used to draw up the map and the descriptive notes. This is followed by reproductions of the main textual documents used and the unique Roman map (the famous Tabula Peutingeriana, conserved in Vienna), the descriptive notes on the sites, all presented in the same format (name, identification and location, history and legal status, archaeology, Christianity and essential bibliography) and a comprehensive topographical index.
