“Until now, we had thought that Old Kingdom mummification was relatively simple, with basic desiccation – not always successful – no removal of the brain, and only occasional removal of the internal organs. The materials used, their origins, and the trade routes associated with them will dramatically impact our understanding of Old Kingdom Egypt.

Professor Salima Ikram, head of Egyptology at the American University in Cairo and a leading expert on the history of mummification, told the Observer: “If this is indeed an Old Kingdom mummy, all books about mummification and the history of the Old Kingdom will need to be revised.” The sophistication of the body’s mummification process and the materials used – including its exceptionally fine linen dressing and high-quality resin – was not thought to have been achieved until 1,000 years later.
