Although short and not in incredible depth, this brief overview of the history and practices of Egyptian mummification packs a lot of fascinating and evocative information into its 120 pages. Despite its length it's surprising how in depth the authors manage to go. One of the real high points, as with all of these Discoveries books, is the excellent selection of photographs and illustrations that compliment the text perfectly and offer more than a description of the historical elements we read about. Many of these photos I've never seen before. I find myself opening the book after having finished it just to revisit its images. This is also what I did for Vikings: the Lords of the Seas, another book in the 'Discoveries' series.
Despite having seen mummies in museums and watched semi-informational televised specials years ago, as well as having seen numerous fictionalized representations including the 1999 Brendan Fraser box office smash hit The Mummy, it's accurate to say that 99% of my knowledge of mummies now comes from this book. It offers sufficient detail and context for most of its duration, with nice nuggets of obscure knowledge here and there and introduces the reader to many people and events they may wish to read about further.
The documents section at the end, another staple of the Discoveries books, is a really great touch, offering excerpts of some of the significant historical documents pertaining to the discoveries of certain tombs, testimonies from Egyptian graverobbers, rituals for mummification, and detailed accounts of recovering artifacts and mummies, as well as the technological advances used to study them.
