While Pompeii and its houses have been subjected to important spatial syntax analyses, no study has sought either to develop implementations of these ideas that approach the Pompeian domestic environment at a finer scale of analysis, or that integrate the role of visibility within the Pompeian house in tandem with movement hierarchy. This volume therefore represents a contribution both to spatial syntax studies through the extension of the theories and methodologies at a refined scale and to Pompeian studies and Roman archaeology in general, revealing the pivotal and reflexive role of architectural space in the activities of Pompeian daily life. Through the application of geographical information systems (GIS)-based study of Pompeian domestic space, it is possible to examine movement and visibility in the domestic landscape at a very fine scale of resolution. The result is not only a better understanding of how Pompeian houses reflected the needs for the activities of daily life imagined by their architects, but also how the architectural spaces served to influence and control these activities from day to day, and ultimately how the spaces themselves were transformed by the spatial and visual requirements of the domestic activities they contained.
