A 300-Year-Old Embalming Riddle Resolved: How Contemporary Science Exposed a Concealed Mortuary Practice
An ancient mystery lying under the stone floor of an Austrian church has at last been deciphered, shedding new light on overlooked mortuary traditions from the 18th century. The remarkably preserved body of a chaplain, once believed to be genuinely mummified, has been found to have undergone an embalming process that had not previously been recorded in historical documents. Thanks to breakthroughs in forensic science and imaging technologies, researchers have unraveled the peculiar and deliberate methods used to preserve this individual after death.
A Curious Figure and an Intriguing Corpse
Located in the serene village of St. Thomas am Blasenstein in Upper Austria, the crypt of the local parish church has discreetly housed the body of a mummy for over 276 years. Informally referred to as the “air-dried chaplain,” this corpse has captivated scientists and onlookers alike because of its remarkable preservation—skin, muscle, and even internal organs remain mostly intact.
Now, a global team of researchers spearheaded by Dr. Andreas Nerlich, a pathologist at Ludwig-Maximilians-Universität in Munich, has definitively identified the mummy as Franz Xaver Sidler von Rosenegg. Historical documents reveal that Sidler was a venerable parish vicar who passed away in 1746 at around 37 years of age.
Preservation Mystery Unraveled with Modern Science
The findings, published in the journal Frontiers in Medicine, detail how Nerlich’s team utilized a blend of CT imaging, radiocarbon dating, isotope analysis, and internal examination to untangle the age-old mystery surrounding the chaplain’s remarkable condition.
In contrast to the prevalent assumption that the crypt’s environmental factors may have inadvertently dried the body, the scans uncovered a far more deliberate approach.
“We discovered that the excellent state of preservation resulted from a unique method of embalming, via the introduction of materials into the abdomen through the rectal canal using wood chips, twigs, fabric, and silk pieces,” explained Dr. Nerlich.
Most strikingly, the team detected large amounts of zinc within the body—particularly zinc chloride, a chemical recognized for its drying and antibacterial properties. This internal application of zinc chloride would have effectively stunted decay by drying out internal tissues and neutralizing bacteria from the inside.
The Elimination of External Incisions
Traditional embalming methods—like those seen in ancient Egypt or later in elite Europe—involved disembowelment through cuts in the abdominal wall. One of the most intriguing components of this case was the lack of such incisions. Rather, the embalming substances were introduced through the rectum, a pathway seldom, if ever, recorded in mortuary texts.
This nuance could clarify why analogous embalming techniques, if they existed, went unnoticed in other mummies of the time.
“This kind of preservation might have been much more common but went unrecognized in instances where the body wall had deteriorated,” Nerlich noted.
A Peek Into a Chaplain’s Existence
In addition to unraveling a grim medical enigma, the research provided a brief glimpse into Sidler von Rosenegg’s existence. Isotope analysis of his bones and teeth indicated a balanced, high-quality diet that aligned with his social position. The team also identified physical signs indicative of pipe smoking and uncovered clear proof of pulmonary tuberculosis—a prevalent and often deadly illness in the 18th century.
Ultimately, researchers surmised that he likely fell victim to acute pulmonary hemorrhage, a complication stemming from his illness, at a young age.
Revealing a Lost Embalming Custom
This significant discovery highlights how collaborative science—melding modern imaging, chemistry, and archaeology—can enhance our comprehension of history. More crucially, it implies that such rectal embalming methods may have been more prevalent in Europe than historical accounts suggest.
By solving the preservation enigma of Franz Xaver Sidler von Rosenegg, scientists are now reevaluating long-standing beliefs regarding how the deceased were prepared for eternity in pre-modern Europe. The chaplain’s mummy, once merely thought to be “air dried,” now serves as a distinct symbol of human creativity and reverence for the departed.
It remains an eerie yet inspiring testament to how far certain communities would go to preserve not just bodies—but also the legacies—of their spiritual leaders.
