Egypt’s Ministry of Antiquities said archaeologists excavated the mummy in Saqqara, a town south of Cairo. The Ministry of Antiquities is planning to announce additional details about the discovery at the end of the month. An ancient Egyptian papyrus version of "Mummification for Dummies" has been revealed by a Danish Egyptologist as the oldest how-to guide yet found. The detailed instructions on the circa 3,500-year-old item adds details to the only two other guides known — and predates them by more than 1,000 years. The papyrus is more than 19 feet long, according to a release from the University of Copenhagen. Known as the Papyrus Louvre-Carlsberg manuscript, the papyrus had been split in two, with one piece at the Louvre Museum in Paris and the other in the University of Copenhagen’s Papyrus Carlsberg Collection.
