A definitive collection of the ancient Egyptian liturgy’s many textual variants. An ancient Egyptian liturgy, The Lamentations of Isis and Nephthys tells the story of how two sister goddesses resurrected the murdered god Osiris. No single version of the poem exists, and various forms have been discovered for use in both formal religious ceremonies and private funerary services. This edition collects all known copies and variants of the ritual text alongside extensive commentary from two leading scholars.
