Investigations of two cemeteries, A and C, in Naqlun have presented a singular opportunity to study changes of burial practices occurring in the Christian community in Fayum over eight centuries, straddling a period of significant political, social and religious changes. Adaptation processes of Byzantine society in Egypt to the new legal and religious regulations introduced successively by the Fatimids and Ayyubids can be traced on the basis of the Naqlun graves.
