Who will say ‘corpse’
to his vivid cast?

Who will say ‘body’
to his opaque repose?
—Seamus Heaney, “Grauballe Man” (1975)

One Saturday in the spring of 1950, brothers Viggo and Emil Højgaard from the small village of Tollund, in Denmark, were cutting peat in a local bog when they uncovered a dead man. He looked as though he had only just passed away. His eyelashes, chin stubble, and the wrinkles in his skin were visible; his leather cap was intact. Suspecting murder, the brothers called the police in nearby Silkeborg, but the body wasn’t what it seemed.

Cracking the case required a special breed of forensic analysis. Famed Danish archaeologist Peter V. Glob, from the University of Aarhus, arranged for the body, along with its bed of peat, to be excavated and transferred to the Silkeborg Museum in a giant wooden box. An examination of the contents of the dead man’s stomach suggested—and radiocarbon dating later confirmed—that he had lived during the third century B.C., in the pre-Roman Iron Age. For more than 2,000 years, Tollund Man, as the corpse became known, had lain at the bottom of the bog, nearly untouched by time, as all of recorded history marched forward over his head.1

Since the 18th century, the peat bogs of Northern Europe have yielded hundreds of human corpses dating from as far back as 8,000 B.C. Like Tollund Man, many of these so-called bog bodies are exquisitely preserved—their skin, intestines, internal organs, nails, hair, and even the contents of their stomachs and some of their clothes left in remarkable condition. Despite their great diversity—they comprise men and women, adults and children, kings and commoners—a surprising number seem to have been violently dispatched and deliberately placed in bogs, leading some experts to conclude that the bogs served as mass graves for offed outcasts and religious sacrifices. Tollund Man, for example, had evidently been hanged.

The bogs are curious tombs, likely harboring homicide victims both honored and disgraced.

The bogs work their magic upon the flesh through the action of a long-chained molecule called sphagnan, found in decaying peat moss. Sphagnan reacts with enzymes secreted by putrefying bacteria, preventing the microbes from breaking down organic matter. At the same time, sphagnan leaches calcium from bones, leaving them bendy like rubber or dissolving them altogether. And because peat moss also contains humic acid, which expels water from soft tissue, skin steeped in bog water turns to bronzed hide. Even the best-preserved bog bodies emerge looking like golems, rudely crafted from leather and mud.

These accidental mummies have inspired generations of scholars and writers, including famed psychologist Carl Jung and the late Irish poet Seamus Heaney. But while nearly 1,000 bodies have been found in the bogs, only a few hundred have been carefully studied. In the first century A.D., Roman historian Cornelius Tacitus offered one of the earliest written interpretations of how they ended up in their watery graves. In his ethnographic work Germania, he alleged that German tribes killed and buried in the bog people who had committed adultery and other “deeds of shame,” including “cowards, shirkers and sodomites.”2

Many scholars have since questioned the accuracy of Tacitus’ claims. But more recent archaeological finds, including the exhumation of Tollund Man, seem to support his theory that the bog was an intentional grave. In his popular book The Bog People, Glob proposes that many bodies were brutally sacrificed in ritual killings to appease a fertility goddess. He and other experts speculate that the people of the Iron Age saw bogs as gateways to the spiritual world. They left behind elaborate offerings, including jewelry, weaponry, battle armor, farming equipment—even butter, impeccably preserved in wooden churns.

Whatever their true meaning, the bogs are curious tombs, likely harboring homicide victims both honored and disgraced: emissaries to the supernatural realm, human payments to the gods, and diseased or offensive citizens, including adulterous wives. Here are five of the most compelling—and cringe-worthy—cases.

Tollund Man: A ritual hanging (375–210 B.C.)

When Glob first laid eyes on Tollund Man, he thought the dead man’s shuttered eyelids and pressed lips conveyed a peaceful expression. Then he saw the leather noose around his neck. Radiograph analysis later showed the man’s tongue was distended, suggesting that he died by hanging. But if he was murdered, he seems to have been laid in the bog with great care, his knees drawn up in the fetal position, his eyes and mouth gently closed.

Glob and other scholars concluded that the 40-year-old Dane must have been a prized sacrifice, perhaps offered to a god or gods to ensure a plentiful harvest, or in exchange for the peat his murders dug up from the bog for fuel. Because the burial custom of the day in Denmark was cremation, some experts have speculated that such human gifts were left whole to provide a deity with a fully functional servant. Others have suggested that these victims were meant to carry special messages or requests to the otherworld.

Oldcroghan Man: A sacrificial king (350–175 B.C.)

In 2003, excavators clearing a drain in a bog between ancient Irish territories came upon the remains of Oldcroghan Man in the bucket of their machine. His death, in his 20s, had been especially violent: He was stabbed fatally in the chest, and then disemboweled and decapitated. A wound on his left forearm suggests he attempted to fend off the attack. When he was unsuccessful, his killers pierced his upper arms and threaded them with spancels—bands made of bark, which were typically used to hobble horses or livestock—in order to stake the corpse to the dense layers of peat at the bottom of a bog pool. In Irish folklore, spancels have magical properties that protect boundaries from invading armies. They are also associated with fertility, given their use during the milking of cattle.

Although all that remains of Oldcroghan Man is a torso, forensic archaeologists extrapolated his height from his arm span. According to their calculations, he was a man of great stature, over 6’3” tall, with enormous, muscular arms. Eamonn Kelly, an expert in Irish bog bodies formerly with the National Museum of Ireland, posits that Oldcroghan Man was a failed king, contender to the throne, or royal hostage sacrificed to a fertility goddess. His carefully manicured fingernails, unworn hands, and last meal (of cereals and buttermilk) imply high social status.3 His nipples appear to have been cut, perhaps as an attempt to make him ineligible for the throne. Suckling a king’s nipples was a medieval gesture of submission that may have extended as far back as the Late Bronze Age, Kelly says. (Other experts argue that the bog itself was responsible for this nipple damage, as well as the immaculate condition of his hands.)

During the Middle Ages, the Irish saw kings as mediators between the supernatural and earthly realms. According to Irish mythology, they were sometimes sacrificed in a ritual that involved a combination of three killing methods, which could include hanging, strangulation, poisoning, drowning, or lacerating by axe, bludgeon, or sword.4 In addition to bodies, worshipers often buried votive offerings in bogs along tribal boundaries, including yokes, cauldrons, weapons, and decorative dress such as gold collars, which were associated with fertility and the inauguration of kings. According to Kelly, these objects defined the borders of a king’s sovereignty—a power overseen by the gods.5

Before he was buried in a bog in Denmark, Grauballe Man was gruesomely executed. After peat cutters dug up his body in 1952, X-ray and computed tomography (CT) scans showed he had received a sharp blow to the legs that brought him to his knees. Then his head was yanked back and his throat was slit from ear to ear. The initial tests also indicated a fracture in his skull, but more detailed scans completed in 2002 revealed it was actually a smooth indentation, suggesting that the damage likely occurred after his death, from pressure in the bog—or possibly when a boy wearing clogs stepped on the corpse during excavation, an accident he confessed to 50 years later.6

Unlike Oldcroghan Man, Grauballe Man, who died in his 20s or early 30s, has no obvious markers of high status or royalty. On the contrary, he may have been poor. An early autopsy of his stomach and intestines indicated that his last meal was of roughly ground corn porridge, a pauper’s diet. More recently, investigations of his tibia showed marks of increased bone density known as Harris lines, which indicate arrested growth and suggest he suffered severe stress, possibly due to malnutrition during early youth or infancy. He also appears to have had slight osteoarthritis in his right knee and his teeth are severely worn, possibly due to an infection.

Experts debate over why he was murdered. Upon examining the corpse, investigators found traces of a hallucinogenic fungus called ergot, now used to synthesize LSD. Some scientists interpret this finding, along with the grisly wounds, as evidence of a ceremonial killing, suggesting that commoners were sacrificed just as readily as kings. Other experts, however, are skeptical. They argue that the bog could have caused Grauballe Man’s leg wound in addition to the dent in his skull. And the ergot in his stomach, they say, probably wasn’t enough to make him hallucinate.

Kayhausen Boy: A slaughtered outcast (500–100 B.C.)1

Human Hide: After his stabbed and bound body was examined, the remains of Kayhausen Boy were placed in a container of ethylene glycol and stored at the National Museum of Nature and Man, in Germany.Department of Legal Medicine, Universitatsklinikum Hamburg-Eppendorf (UKE), Germany

In 1922, a German peat cutter found the mummified body of a 7- or 8-year-old boy wrapped in woolen fabric and a calfskin cloak. He delivered the body to the local natural history museum in a wheelbarrow. One of few children disinterred from the bog, Kayhausen Boy died from repeated stabbings in the throat. His left arm was also cut, a sign of self-defense. His killers had tied his arms behind his back and bound his feet with the calfskin cape, likely to transport the corpse.7

X-rays revealed that Kayhausen Boy suffered from an infected socket at the top of his femur, which would have made it difficult to walk without assistance. He also has Harris lines on his left tibia, suggesting growth disorders from malnutrition or disease. In his book The Buried Soul, British anthropologist Timothy Taylor argues that Iron Age peoples may have believed disabled individuals had special powers. For those who could not walk properly, like Kayhausen Boy, divination or prophecy may have been the only available social role—a gift that could get a person killed if his forecasts didn’t come to pass.8

Yde Girl: A strangled adulteress (54 B.C.–128 A.D.)

She devil: This reconstruction of Yde Girl’s head was made by researchers at Manchester University with the help of CT scans. Her body is kept at the Drents Museum, in the Netherlands.Drents Museum

Yde Girl’s long red hair so terrified the peatcutters who found her in the Netherlands in 1897 that they ran away, believing they had seen the devil. (A study of the pigments in her hair later showed that it was actually blonde, but tannins in the bog had dyed it a fiery red.) After the local newspaper ran a letter about the discovery, archaeologists excavated the remains and delivered them to the Drents Museum. Examiners concluded that the 16-year-old girl had been strangled with a woolen belt and stabbed above her left collarbone.

Like Kayhausen Boy, Yde Girl might have been killed for her physical deformities. CT scans revealed evidence of scoliosis, an abnormal curvature of the spine. And her right foot was swollen and appeared pigeon-toed, suggesting a limp. But her hair offers an alternative explanation: Sheared on one side of her scalp, it was left chest-length on the other. In medieval times, this was a mark of disgrace reserved for cheating wives, implying that Yde Girl may have been executed for infidelity.
