Reshaping the Urban Space: Bakchias in Ptolemaic and Roman Times

The paper focuses on some important results obtained by an integrated approach using archaeological evidence, papyrological sources and different kinds of technologies in order to reconstruct the urban development of the site of Bakchias, located in the north-eastern part of the Fayyum region (Egypt). The Mission of Bologna University has excavated ancient Bak-chias at Kom Umm el-Athl for over twenty years. In particular, the latest studies, conducted in partnership with Sapienza University of Rome since 2005, have revealed several new elements which are useful for reconsidering the urban development of the kome. In 2011, a GIS was constructed not only in order to store and manage the large quantity of data collected during these years, but also to analyse and process the information and to optimise the research goals. Indeed, the latest-field activities have brought to light numerous structures, both public buildings and private houses in different sectors of the archaeological area. At the same time, an analysis of the papyrological and epigraphic sources was carried out so as to comprehend the useful information about the spatial content, activities and buildings recorded for the set-tlement. The research was completed using different surveying approaches. All the data thus obtained were merged together in a GIS environment, in order to collect and manage all the information and to integrate the individual elements in a coherent workflow process. Spatial or distributional analysis of the data relating to the site enabled us to draw a series of thematic and phase maps of the Bakchias site. The execution of these diachronic plans, representing different chronological phases of the town, allowed us to evaluate the historical development of the site and urban plan transformations. 300
