Most copies of the Book of the Dead from the Late and Graeco-Roman Periods are written on papyrus, but from the 5th century BC on, the formulae of this funerary text were also inscribed on mummy bandages, a practice perhaps originating in the city of Memphis. The Book of the Dead of Nanefbastet, written on one single piece of bandage 8 metres in length, bears texts in hieratic accompanied by vignettes, all taken from chapters 1-17 of the Book of the Dead.
