Stacked Mummies Reveal 700 Years of Changing Burial Rituals in Ancient Egypt

The shift from placing mummies individually to stacking bodies in a Theban tomb shows how burial practices and their symbolic meanings changed over time.

In tomb TT 209, an ancient Egyptian burial place in the Theban Necropolis opposite Luxor, four human mummies and a mummified dog were buried one above another. The dog rested directly on top of the mummies of a man and a woman.

These stacked burials were part of a much longer history of people making room for the dead. Researchers in Spain who studied the tomb’s third chamber found evidence that its increasingly crowded arrangements reflected deliberate choices and changing rituals. Their findings, published in Frontiers in Environmental Archaeology, suggest that new burials transformed the space while retaining connections to those already there.

The group of four people and the dog occupied the chamber’s southeastern section and dates to the Ptolemaic period, which lasted from 305 to 30 BCE. The animal’s position raises questions about both its relationship with the people below it and its possible role in their burial.

“One detail I find quite beautiful is the presence of a mummified dog placed directly on top of the mummies of a man and a woman,” said first author Dr. Jared Carballo-Pérez, a researcher at the University of La Laguna. “This could indicate a close relationship between these human individuals and the animal, an idea that I think is quite easy to empathize with.”

“It could also reflect a further change in ritual practice, with an animal taking on the role of a psychopomp, a symbolic helper in the journey to the afterlife,” added senior author Dr. Miguel Ángel Molinero Polo, a professor of Egyptology at the University of La Laguna.

Older burials shaped new arrangements

TT 209 is one of more than 400 tombs in the Theban Necropolis. It was built during the Twenty-fifth Dynasty, which lasted from 754 to 656 BCE, and remained in use until its abandonment during the Ptolemaic period. To reconstruct the chamber’s history, the researchers excavated it, photographed the mummies, and made sketches and written descriptions documenting each body’s position, orientation, and relationship to the tomb’s structures.

The chamber contained nine funerary deposits, including individual and multiple burials, along with objects placed with the dead.

“We found a total of 16 mummified human individuals, a mummified dog, and a disturbed deposit containing the remains of at least four individuals,” said Carballo-Pérez. “The detailed study of the bodies indicates neither chaotic accumulation nor a loss of the original ritual over time. Rather, there was a spatial logic in which each new deposition was adapted to the presence of previous bodies – a kind of funerary memory in the processes of reuse.”

From separate coffins to stacked mummies

Differences in the objects accompanying the dead helped the researchers distinguish burial practices across that history. The earliest burials were relatively spread out.

“The earliest individuals buried here appear to have been of high social standing, as they were interred in coffins, with funerary nets and amulets, and with an assemblage containing costly items, such as the contents held in Phoenician amphorae, a large number of which were found alongside them,” said Molinero Polo.

Amphorae are storage vessels. In the later stacked burials, the researchers found a different combination of containers and treatment of the bodies.

“The bodies buried in vertical superposition did not have coffins but were carefully mummified. They also can be associated with upright jars that point to a specific ritual not found in the earlier phases of the tomb’s use,” said Molinero Polo.

The bodies themselves recorded how the use of space changed. During a span from around 680 to 404 BCE, encompassing the later part of the Twenty-fifth Dynasty and the Persian period, new bodies began to occupy whatever room remained. Some had an arm folded inward, unlike the typically extended arms of earlier burials.

During the Persian period, the arrangement also shifted from individual deposits to bodies placed in layers. Across the chamber, the researchers found bodies resting above others in two-thirds of the burials. Later deposits included people whose arms were both folded over their chests, a posture Egyptologists call the Osirian position.

Floods and fires complicate the evidence

The surviving arrangements cannot reveal every decision made by the people who returned to the tomb.

“We have few details regarding how the people who entered tombs behaved, what their motivations were in each historical period, and how they conceptually reconfigured the pre-existing space,” said Molinero Polo.

Centuries of use also complicated the physical evidence. The chamber flooded repeatedly, experienced fires, and was entered again by people who moved debris within the tomb. In some deposits, these disturbances make it difficult to establish the exact order of burials or determine the intentions behind them.

“Nevertheless, what we present means that deposits that were previously considered ‘disordered’ can be reinterpreted,” concluded Carballo-Pérez. “This helps us develop a better understanding of the social behaviors behind funerary practices.”
