A Coffin in the Peat
On a day in February 1921, a farmer named Peter Platz was removing a burial mound, or tumulus, from his field near the village of Egtved when he discovered a large, sealed coffin made from a hollowed-out oak log. The coffin was transported to the National Museum of Denmark in Copenhagen, where it was opened. Inside, incredibly preserved by the acidic, low-oxygen bog conditions, lay the remains of a young woman who died on a summer day in 1370 BCE.
The waterlogged environment and tannic acids from the oak prevented the complete decay of organic materials. While her skeleton had dissolved, her short blonde hair, teeth, nails, and even parts of her brain and skin remained. She was 16 to 18 years old, stood about 160 cm tall, and was laid on a cowhide. She wore a well-preserved outfit: a short-sleeved wool blouse and a knee-length skirt made of twisted wool cords. A large, circular bronze belt plate decorated with spirals rested on her waist. Alongside her were a horn comb, bronze bracelets, a small earring, and a bark box containing a hairnet and an awl. At her feet, archeologists found the cremated remains of a 5-to-6-year-old child and a birch bark bucket that once contained a fermented beverage made of wheat, honey, bog myrtle, and cowberries.
A Traveler's Tale in Strontium
For decades, the Egtved Girl was assumed to be a local of high status. Modern science revealed a far more complex history of mobility in Bronze Age Europe. The answer was strontium, a chemical element whose isotopic ratios (specifically ⁸⁷Sr/⁸⁶Sr) vary depending on local geology. Humans absorb these specific geological signatures through food and water, locking a permanent record of their childhood location into their tooth enamel.
Analysis of the Egtved Girl’s first molar showed a strontium signature that did not match the Jutland peninsula in Denmark. Instead, it pointed to an origin hundreds of kilometers to the south, with the Black Forest region of Germany being the most likely match, some 800 km away. The wool in her clothes and the oxhide she lay on also originated from outside Denmark.
Even more detailed information came from her 23-centimeter-long hair. Since hair grows continuously, it preserves a timeline of a person's location. The strontium analysis of different segments of her hair showed that she had traveled extensively in the last two years of her life. The data indicates she moved from her German home to Jutland, stayed for about nine months, returned to Germany for four to six months, and then made a final journey back to Egtved just a month or so before her death. This evidence suggests established networks of travel and exchange existed across the continent, possibly for trade or marriage alliances.
