Mystery of Mummified Lung Solved

New analysis reveals that a copper belt might have contributed to the mummification of a lung belonging to Merovingian royalty.

The mystery of how a lung from ancient French royalty became mummified has been solved after decades of uncertainty, according to an international team of researchers.

In 1959, a preserved lung was uncovered by archaeologist Michel Fleury inside a stone sarcophagus in the Basilica of St Denis, Paris, the site where the kings of France have been buried for centuries. The lung was found with a skeleton, a strand of hair, jewelry and several fragments of textiles and leather.

On a gold ring, the inscription "Arnegundis" around a central monogram "Regine" revealed the remains belonged to the Merovingian Queen Arnegunde (about 515–about 580), one of the six wives of King Clotaire I (511-561) and the mother of King Chilpéric I (about 534-584).

Since the discovery, the fine preservation of the lung raised questions over whether her lung had naturally mummified or had been embalmed.

"From a macroscopic point of view, the lung appears nicely preserved, while the body is completely skeletonized," Raffaella Bianucci, a bio-anthropologist in the Legal Medicine Section at the University of Turin, told Discovery News.

It turns out an elaborate copper belt played a key role in the lung's mummification.

The international team led by Bianucci presented the results of their investigation at the International Conference of Comparative Mummy Studies in Hildesheim, Germany.

Scanning electron microscopy on the lung biopsies revealed a massive concentration of copper ion on the surface of the lung tissue. Other analysis turned up massive concentrations of a copper oxide throughout the lung biopsies.

Further biochemical analysis showed the presence of benzoic acid and related compounds in the lung, although at low levels.

"These substances are widespread in the plant kingdom and similar profiles have been already reported in the balms of Egyptian mummified bodies," Bianucci said.

According to the researchers, the findings support the theory that, as suggested by historians, Arnegunde might have undergone an oral injection of a fluid made of spices/aromatic plants.

"Since Arnegunde was wearing a copper alloy ... belt around her waist, we speculate the copper oxide in the lungs is from weathering of the belt," Bianucci said.

"The preserving properties of copper, combined with the spice embalming treatment, might have allowed the preservation of the lungs," she added.

Historical accounts indicate that artificial mummification, based on the use of spices and aromatic plants, was used in sixth century France to treat the bodies of kings, queens, holymen and holywomen.

The Merovingians embalmed these elite individuals following a procedure they had learned from the Romans, which they, in turn, had adopted from Egypt.

"Clearly the Merovingian mummification was much less sophisticated," Bianucci said, "It was essentially based on the use of oil and resin-soaked linen strips used with spices and aromatic plants such as thyme, nettles, myrrh and aloe," Bianucci said.

"Queen Arnegunde is a particularly complex case," Bianucci said. "Since she was exhumed in 1959, her remains underwent several displacements, disappearing in the 1960s to finally resurface in 2003."

Investigations on Arnegunde' skeletal remains revealed the queen was 5'1″ tall and around 61 years old when she died of unknown causes.

Albert Zink, Head of the EURAC Institute for Mummies and the Iceman in Bolzano, found the research to be similar to the case of a Coptic mummy, dating from about 600-1000 A.D.

"During the study of this mummy we discovered the body did not undergo organ and brain removal. Instead, it appears that an embalming solution was injected through the mouth," Zink told Discovery News.

"Just like in the case of the Merovingian queen, the liquid agglomerated in the lung, which is the only organ that is well preserved," Zink said.

Mummy Identification Still Uncertain Science

Queen Arnegunde represents one of the few specimens from the Early Middle Ages for whom researchers have both an historical account, human remains and artifacts. Moreover, Arnegunde belonged to Merovingian royalty.

Distinctive for their shoulder-length hair, these Frankish kings ruled in parts of France and Germany from the fifth to the eighth centuries, establishing the most successful post-Roman kingdom in western Europe.

More recently, the Merovingians became popular with the publishing of Dan Brown's "Da Vinci Code," which revived the story that Jesus Christ and Mary Magdalene had married and their bloodline survived in the Merovingian dynasty.

In 2006, DNA analysis of a sample from Arnegunde' skeletal remains was arranged and filmed in a documentary.

The aim was to check whether she had a Middle Eastern haplo type. She did not. A princess of Thuringia, daughter to King Baderic, Arnegunde had married into the dynasty and was not a direct descendant of the Merovingian line.

Bianucci and colleagues were not interested in conspiracy theories but rather focused on the mummified lung.

A young, short man with a slight resemblance to Michael Jackson, a woman with an elaborate hairstyle and an older woman who could slip, unnoticed, into today's society -- all died some 2,000 years ago but now facial reconstructions of the ancient Egyptians have brought them back to life.

The reconstructions were unveiled today at McGill University's Redpath Museum.

"People are amazed by mummies, but never more so, I've found, when they can see the face," said anthropologist Andrew Wade of Western University.

The high tech process, involving CT scanning and multiple scientific disciplines, recreates what the three individuals looked like as they were laid to rest nearly 2,000 years ago.

Here, a mummy is set to go into a CT scanner.

Mummies of a young male, a young female and an older woman were virtually unwrapped using CT scanning. Models of their bone structure were then created.

Barbara Lawson, a curator at the Redpath Museum who also worked on the project, added that all three mummies were scanned at the Montreal Neurological Institute and Hospital as part of Western University's IMPACT Radiological Mummy Database Project.

Forensic artist Victoria Lywood undertook the actual reconstruction work, which was based on the 3-D high-resolution images along with ultrasonic images and anthropological research.

A step in the process involved sketching what the individuals would have looked like.

Some have detected a facial resemblance, at least from the front profile, with the late pop star Michael Jackson. Jackson was, in fact, very interested in Egyptian history, which might have influenced some of his personal style.

The Theban male died between the ages of 20-30. His mummy was purchased in Thebes, his likely place of death.

The young man was "relatively short in stature," according to Wade.

Lywood is one of the world's leading experts on such recreations.

"I reconstruct modern-day skulls, archaeological remains and fragmentary skulls," she told Discovery News. "The oldest I have constructed was from 6,000 years ago found in Israel. While there were people of all sizes throughout the ages, my experience is that skull size was much smaller than modern populations."

This Ptolemaic female was a "late adolescent girl or young woman of average height and elite status," Wade said. "Her age at death is estimated at between 18 and 24 years."

Her mummy was found "in a tomb pit in the solid rock near Hawara el-Makta in Fayum (Lower Egypt) and acquired in Egypt towards the end of the 19th century and donated to the Redpath Museum in 1895," Lawson said.

Clearly ancient Egyptians prized fashionable coifs, given the complexity of the young woman's hairstyle.

Her hair must have been fixed before mummification, perhaps in hopes of sending her off to the next life looking her best.

The hairdo of a young ancient Egyptian female was reconstructed on a modern woman.

The reconstructed young woman is shown here without her wig. Clearly her hair was a big part of her look.

The oldest individual of the three was this woman -- likely a tall, upper middle-class adult between the ages of 30 and 50 years old.

If she were alive today, this woman (at least based on her physical appearance) would probably fit right in with modern society.

As Wade said, "Humans have been physically pretty much the same for the last 2,000 years...That's not to say that evolution has stopped working on us, but the time frame of 2,000 years is just a drop in the bucket for noticeable physical changes and we've reduced the need for physical changes by adapting culturally."

The three ancient Egyptian people died at somewhat different times and never knew each other. But, as reconstructions, the early Egyptians will spend even more time together, because they will star in a new display in the Redpath Museum's World Cultures gallery starting in February.
