Bog Bodies: See The Pre-Egyptian Mummies Made By Nature

As much as 10,000 years old yet shockingly well-preserved, bog bodies like the Tollund Man are more incredible than any manmade mummy.

In 1950, two Danish brothers stumbled across a human body while collecting peat from a bog outside of Silkeborg. Terrified, they immediately notified the police. The body appeared to be just days old, and they assumed it was a murder victim. But radiocarbon dating told quite a different story. It was actually a 2,000-year-old bog body.

The bog body, nicknamed the "Tollund Man" after the village where the boys came from, belonged to someone who had died between 375 and 210 B.C.E. He was found naked with noose hanging around his neck and a sheepskin hat on his head. Researchers believe that he was likely a human sacrifice.

And he's just one of many bog bodies that have been uncovered in Europe.

What Are Bog Bodies?

The Tollund Man was discovered by two boys in 1950. His body is so well-preserved that they thought he was a recent murder victim.

Bog bodies — corpses mummified and preserved by the highly acidic water, low temperature, and a lack of oxygen found in peat bogs — have been turning up for hundreds of years. The first recorded discoveries of bog bodies began in the 17th century, and dozens have been found since.

Though the oldest bog body ever found dated back to 8000 B.C.E., not all of them are ancient. In the 1990s, the well-preserved bodies of Russian soldiers killed during World War II were discovered in bogs in Poland. And though most bog bodies have been found in Europe, they've appeared elsewhere too. In the U.S., Native American remains have been found in Florida bogs.

This unique environment of bogs can perfectly preserve the skin and internal organs of a human — as well as their hair, fingernails, and stomach contents.

The Famous Bog Bodies Of Western Europe

The Tollund Man is one of the most famous bog bodies ever discovered. But he's just one of many bog bodies to emerge from Europe's peat bogs.

Like the Tollund Man, the Grauballe Man was discovered in the 1950s. And like the Tollund Man, he was so well-preserved that he appeared to be a recent corpse. After all, he still had a full head of flaming red hair.

Grauballe Man With Hair

Moesgaard MuseumThe Grauballe Man is so well-preserved that he still has a healthy head of hair — though the chemical composition of the peat bog likely changed the color over time.

"I stood on the shovel and it wobbled like a rubber ball," Tage Busk Sørensen, the peat-cutter who discovered the body in 1952, recalled of his eerie discovery according to the Moesgaard Museum. "I hit him right on the shoulder. There was the head so fine. I had to get down on my knees to see if it really was a human head. Then I realized it really was."

An examination of the body revealed it to be some 2,300 years old. The Grauballe Man was around the age of 30 years old when he died, stood about five feet and seven inches tall, and retained his full head of hair. Though it appeared bright red, it's unlikely that it was this color during his life — the chemical composition of the bog changed its hue over time.

Half a century earlier, another well-preserved bog body was discovered in the Stijfveen bog near the Dutch village of Yde. Two laborers were dredging peat on a spring day in 1897 when a dark human form suddenly surfaced from beneath the water. Believing it to be the devil, they fled.

But the human form they'd seen was actually a 2,000-year-old bog body.

Since nicknamed the "Yde Girl.", this bog body was once a 16-year-old girl who died between 54 B.C. and 128 A.D. She stood at about four and a half feet tall and appeared to suffer from a severe case of scoliosis.

The Yde Girl was not as well preserved as some other bog bodies, but likely suffered a similar fate.

The Yde Girl was not in as good condition as the Tollund Man or the Grauballe Man, but these three bog bodies had one gruesome thing in common. Like many of the other human remains dredged from peat bogs, they were likely the victims of ritual sacrifice.

How Did These People Die?

Each of the three bog bodies mentioned so far appeared to have died violent deaths. The Tollund Man was discovered with a rope around his neck, which is why researchers believe that he was hanged.

Though it's possible he was a criminal, that he died by suicide, or that he was murdered, researchers have reason to believe that he was a sacrifice victim. The Tollund Man was laid to rest by someone who closed his eyes and his mouth and, significantly, he was buried in a bog and not in the earth.

Likewise, the Grauballe Man and the Yde girl both appear to have been sacrificed. Researchers found that the Grauballe Man had a broken shin bone and a slit throat. The Moesgaard Museum speculates that a priest broke his leg with a club, forcing him onto his knees. Then the priest may have grabbed his hair, yanked his head back, and slit his throat.

The Yde Girl also died a violent death. The Drents Museum reports that she was strangled by a "woolen band" that was wrapped around her neck three times and possibly stabbed in the neck.

That said, not all bog bodies were necessarily human sacrifice victims. Though many other bog bodies bear marks of violence — including the Clonycavan Man, Old Croghan Man, and the Lindow Man — others do not. Some may have merely drowned while attempting to cross the treacherous landscape. Others may have indeed died violent deaths, but were perhaps victims of murder and not ritual sacrifice.

In all, each bog body tells a slightly different story. Found in different places and hailing from different times, these people lived unique lives — and died unique deaths. Their facial features, gruesome injuries, and even the curious contents of their stomachs tell a fascinating story about how ancient humans lived and died hundreds or even thousands of years ago.
