The correct answer is : The Book of the Dead.
The Book of the Dead is an ancient Egyptian funerary text, a collection of magic spells which enable the soul of the deceased to navigate the after life.
These spells were designed to provide protection and help to the spirit of the dead person. The afterlife was considered to be a continuation of life on earth. The spirit had to pass many difficulties and judgement in the Hall of True before it could reach a paradise. The spells were there to assist the spirits during the passage, giving them instructions and enabling them to assume the form of several mystic creatures. It also contained passwords necessary for admittance to certain stages to the underworld.
The spells were usually written on a tablet or a sarcophagus instead of papyrus, this was the reason why many copies survived.
