New research suggests that a set of 8,000-year-old human skeletons buried in Portugal’s Sado Valley could be the world’s oldest known mummies.
Based on photographs taken of 13 bodies when they were first exhumed in the 1960s, researchers have been able to reconstruct likely burial positions, shedding light on mortuary rituals used by European Mesolithic peoples.
The study, published in the European Journal of Archaeology by a team from Uppsala University and Linnaeus University in Sweden and the University of Lisbon in Portugal, suggests that people in the Sado Valley were engaging in desiccation through mummification.
Today, the soft tissue on the bodies is no longer preserved, which makes looking for signs of such preservation challenging. Experts used a method called archaeothanatology to document and analyze the remains, and also looked to the results of decomposition experiments conducted by the Forensic Anthropology Research Facility at Texas State University.
Based on what we know about how the body decomposes, as well as observations about the spatial distribution of the bones, archaeologists made deductions about how the people of the Sado Valley handled the bodies of their dead, which they buried with the knees bent and pressed against the chest.
As the bodies gradually became desiccated, it appears that living humans tightened ropes binding the limbs in place, compressing them into the desired position.
If the bodies were buried in a desiccated state, rather than as a fresh corpse, that would explain some of the signs of mummification practices.
The people of the Sado Valley may have chosen to mummify their dead for ease of transport to the grave, and for the body to better retain its shape in life after burial. If European mummification practices do indeed date back thousands of years prior than previously known, it could enhance our understanding of Mesolithic belief systems, particularly as they relate to death and burial.
Most of the world’s surviving mummies date from no earlier than 4,000 years ago, although evidence suggests the ancient Egyptians may have begun the practice as early as 5,700 years ago.
The bodies of the Chinchorro mummies from coastal Chile, long believed to be the world’s oldest mummies, were intentionally preserved by the region’s hunter-gatherers around 7,000 years ago
