In the Predynastic period, before the rise of the Pharaohs, ancient Egyptians buried their dead directly in the hot, dry desert sands. The natural arid conditions acted as a primitive form of preservation, desiccating the bodies and preventing decomposition. These simple burials, often in shallow pits, led to accidental mummification as the desert sands rapidly absorbed moisture. Early communities likely noticed that bodies buried in this way remained intact, sparking the realization that dryness was key to preservation.
As Egyptian society evolved, so did burial practices. The transition from pit burials to more elaborate tombs posed new challenges, as the enclosed environments led to faster decomposition. To counter this, early experiments with artificial preservation began. Initially, these efforts were rudimentary, involving simple wrappings and the use of resins. Over time, embalmers refined their techniques, experimenting with salts, oils, and various substances to dry and protect the body. By the Old Kingdom period, the practice had transformed into a highly ritualized and sophisticated process.
