In addition to the formal reliefs and texts, the limestone revetment and columns in the superstructure of the tomb of Ptahemwia bear several dozen unofficial inscriptions and depictions, some incised, some written in red ochre (dipinti). These graffiti warrant further analysis for two reasons. First, they provide strong, contextualised evidence about the various ways in which the tomb of Ptahemwia was used. Second, they have the potential to shed new light on a shadowy area of Egyptian religious history: the study of aspects of popular piety.
