Here are some resources for those wishing to delve a bit further into death and mummification.
Death and Salvation in Ancient Egypt, by Jan Assmann (translated by David Lorton). This is a my favorite treatment of death in ancient Egypt. Its definitely scholarly, and focuses more on the conception of death and the afterlife than mummification and burial practices, but I think it is accessible enough for most readers who interested in ancient Egypt.
Death and Burial in Ancient Egypt, by Salima Ikram. Salima is the world’s foremost expert on the art of mummification and she has even done some experimental mummification herself.
The Mummy in Ancient Egypt: Equipping the Dead for Eternity, by Salima Ikram and Aidan Dodson. Another good book by Salima. This focuses more purposefully on the mummification and burial–but it will have some content overlap with Death and Burial in Ancient Egypt. I would recommend starting with one or the other first.
Burial Customs in Ancient Egypt: Life in Death for Rich and Poor, by Wolfram Grajetzki. This book provides a wider view of burial customs, instead of focusing solely on royal tombs and wealthy burials.
Egyptian Mummies and Modern Science, by Rosalie David. This is a more scholarly work, but will be of interest to those interested in the more scientific techniques currently employed by scientists to study mummies (DNA, palaeopathology, conservation, etc.).
