“The original word [for mummy] written in hieroglyphics is krst, whence kas, to embalm, to bandage, to knot, to make the mummy or karast (Birch, Dictionary of the Hieroglyphics, pp. 415-416; Champollion, Grant. Egyptienne, 86). The word krs denotes the embalmment of the mummy, and the krst, as the mummy, was made in the process of preparation by purifying, anointing, and embalming. To Kara's the dead body was to embalm it, to bandage it, to make the mummy. The mummy was the Osirian Corpus Christi, prepared for burial as the laid-out dead, the karast by name.”
