The impact of a changing environment on human society and, conversely, the impact of man's activities upon the environment are important and contentious subjects today. Climatic and environmental change have also been credited with bringing about major shifts in human history. One such case is that of the decline of Roman North Africa and its conquest by the Arabs. The evidence for this process is, however, far from clear-cut, and Professor Shaw's concern in these studies is firstly to re-examine what is known, from both archaeological and written sources, and how it has been interpreted, work which has led to some substantial revisions of accepted accounts. In the final three articles he turns to analyse how Roman society functioned on the edge of the desert and, in particular, to investigate the careful exploitation and control of critical water resources.

One route to understanding the nature of specifically religious violence is the study of past conflicts. Distinguished ancient historian Brent D. Shaw provides a new analysis of the intense sectarian battles between the Catholic and Donatist churches of North Africa in late antiquity, in which Augustine played a central role as Bishop of Hippo. The development and deployment of images of hatred, including that of the heretic, the pagan, and the Jew, and the modes by which these were most effectively employed, including the oral world of the sermon, were critical to promoting acts of violence. Shaw explores how the emerging ecclesiastical structures of the Christian church, on one side, and those of the Roman imperial state, on the other, interacted to repress or excite violent action. Finally, the meaning and construction of the acts themselves, including the Western idea of suicide, are shown to emerge from the conflict itself.

The studies collected in this volume cover three broad areas of the history of North Africa as part of the Roman Empire. Studies devoted to the history of 'political institutions' are followed by ones that detail aspects of interactions between nomad and sedentarist communities in the African provinces. The book concludes with two studies on African christianity. In all of these, special attention is given to the indigenous institutions, economies and beliefs that informed the confrontation between 'African' and 'Roman'. The studies in general argue for a strongly 'interactionist' approach to historians' reconstruction of the history of the period and the region - a perspective that would emphasise the continuous conflict between the two world of African and Roman.
