 These writings are known as the "Coffin Texts".After a person died, his or her corpse would be mummified and wrapped in linen bandages in order to ensure that the deceased's body would survive for as long as possible because the Egyptians believed that a person's soul could only survive in the afterlife for as long as his or her physical body survived here on earth.The last ceremony before a person's body was sealed away inside the tomb was known as the "Opening of the Mouth".
