A mummy is a corpse whose body is artificially or naturally preserved. The corpse is first treated with chemicals, coldness, or dehydration. Then it is embalmed with salt or other dehydrating materials. Some rituals requires anointment of the corpse with oils or perfumes. The mummification is completed by wrapping the treated corpse with white cloth or linen, much like how you wrap a person’s body with bandage. A sheet of canvas may be used on the outer layer to further protect the corpse.
