This volume presents the results of a research project extending over four decades on the identification, location and character of the archaeological sites of Lower Egypt. The project has been known since 1997 as the Egypt Exploration Society’s Delta Survey (supported by the British Academy). Data has been gathered from bibliographic sources, dedicated fieldwork and information from Egyptian and foreign missions in order to present a body of material previously available only in summary online. The book provides all the information in enhanced and extended form, with descriptions of each site, noting especially changes in condition over time, previous discoveries and current fieldwork, together with key references to bibliographic or other sources. This is an essential index of the ancient settlements of the Delta, alerting archaeologists and historians to the large cities, small towns, fortress and temple sites that covered the Delta in antiquity.
