3. The Book of the Dead, the most famous relic of Egyptian literature, is a collection of pieces many of which are very ancient, bearing on the passage of the soul through the under-world. The book has also been called the _Funeral Ritual_; a better translation of the title is, "Book of Coming out from the Day." The earthly life is the day from which the deceased comes forth into the larger existence of the world beyond. The book (or such parts of it as may be used in each case) is the soul's _vade mecum_ for the under-world, and contains the forms the soul must have at command in order to ward off all the dangers of that region, and to secure an easy and happy passage through it. How the person is to be reconstructed, the different parts coming back to be built up again in one, how he is to know the spirits he meets, how he is to get the gates opened for him,--such are the subjects of various chapters; and the soul's success in its passage depends on its knowledge of these. The words they contain are not merely information, they have magic power to smooth away obstacles and to open doors. Hence it is important for a man to have learned them when alive, and, to assist his memory, a few chapters are written on papyrus or linen, and the rolls placed with the mummy in its case, or they are written on the walls of the tomb. No other Egyptian work, in consequence, has been preserved in so many copies, but one roll or set of inscriptions contains one set of chapters and another another set.
