Ole Ginnerup Schytz, an engineer in Denmark’s sleepy Vindelev agricultural area, had used a metal detector only a handful of times when he found a bent clump of metal in a friend’s barley field. He figured it was the lid from a container of tinned fish and tossed it in his junk bag with the other bits of farm trash that had set his metal detector beeping: rusty nails, screws, scrap iron. A few paces away he dug up another shiny circle. Someone had clearly enjoyed a lot of tinned fish here—into the sack it went. But when Ginnerup found a third metal round, he stopped to take a closer look. Wiping the mud from its surface, he suddenly found himself face-to-face with a Roman emperor. At that point he had to admit “they weren’t food cans,” Ginnerup recalls with a chuckle.
After a brief intermission for an online Teams meeting for work that December day in 2020, Ginnerup dug up 14 glittering gold disks—some as big as saucers—that archaeologists say were buried about 1,500 years ago, during a time of chaos after ash clouds from a distant volcanic eruption created a miniature ice age. Four medallions feature Roman emperors, and several bear intricate geometric patterns. But the real showstopper is an amulet called a bracteate with two stylized designs: a man in profile, his long hair pulled back in a braid, and a horse in full gallop. An expert in ancient runes says she was awestruck when she finally made out the inscription on top: “He is Odin’s man.”
These embossed runes are the oldest known written mention of Odin, the Norse god of war and ruler of Valhalla. Ginnerup’s bracteate, which archaeologists describe as the most significant Danish find in centuries, extended the worship of Odin back 150 years—and it’s all because Ginnerup received a metal detector as a birthday present from his father-in-law.

Many other European countries have prohibited or heavily restricted hobbyist metal detecting, but Denmark has embraced it, creating a system for members of the public to hand over finds to government archaeologists. The result has been an embarrassment of riches, with more than 20,000 items turned in annually in recent years. The curators assigned to identify and catalog the artifacts can’t dream of keeping up, but the fruits of their collective labor are clear: whereas neighboring countries have only vague sketches of the past, metal detectorists have filled in the ancient map of Denmark with temple complexes, trade routes and settlements that would have otherwise been lost to history.
“Private detectorists have rocketed Denmark ahead of its neighbors in archaeological research,” says Torben Trier Christiansen, curator of archaeology at Denmark’s North Jutland Museums. “There’s nothing ‘amateur’ about them.”
Denmark has been inhabited since the end of the last ice age, when nomadic hunter-gatherers from southern Europe arrived following the migration of reindeer and retreating glaciers as early as 12,500 years ago. The ancestors of modern ethnic Danes showed up some 5,000 years ago, journeying from the steppes of what is now Ukraine and southwestern Russia. Their descendants lived in small farming communities across Scandinavia for thousands of years, building megaliths and barrows for their honored dead and making human sacrifices in bogs to appease their gods.
In the early centuries of the common era, these farming communities coalesced into a series of Germanic tribes—the Cimbri, the Teutons, the Jutes, the Angles and the Danes—who became skilled seafarers, explorers and metalworkers. Because precious metals—including silver, gold and the components of bronze—do not occur naturally in what is now Denmark, its denizens had to barter for or steal these metals from abroad. They traded extensively with the Roman Empire, which never reached as far north as Scandinavia.
