The British Museum's collection of late hieratic religious papyri, particularly those of the Graeco-Roman period, is one of the most important in the world, in terms both of its number and its diversity. The papyri mainly comprise funerary texts laid beside the deceased as guides in the underworld, but also temple rituals, liturgies and texts of magical inspiration. For each of the fifty or so documents catalogued the author provides a general introduction, a translation and a commentary.
