One of the sources Joyce drew from is the Ancient Egyptian story of Osiris, and the Egyptian "Book of the Dead," a collection of spells and invocations. Bishop asserts that "it is impossible to overlook the vital presence of the "Book of the Dead" in "Finnegans Wake", which refers to ancient Egypt in countless tags and allusions." Joyce uses the "Book of the Dead" in "Finnegans Wake", "because it is a collection of the incantations for the resurrection and rebirth of the dead on the burial". At one of their final meetings, Joyce suggested to Frank Budgen that he write an article about "Finnegans Wake", entitling it "James Joyce's Book of the Dead". Budgen followed Joyce's advice with his paper "Joyce's Chapters of Going Forth by Day", highlighting many of the allusions to Egyptian mythology in the book.
