A 2,400-year-old fingerprint on Scandinavia’s oldest war boat unveils Baltic raiders’ distant origins, offering a direct human link to ancient warriors who echo the Viking spirit of self-reliance and bold exploration.
Story Highlights
- Researchers discover partial human fingerprint in caulking of Hjortspring boat, dated 381–161 BCE, providing rare “direct touch” from Iron Age raider.
- Chemical analysis confirms the boat originated from pine-rich Baltic coasts, hundreds of kilometers away, revealing organized long-distance maritime raids.
- Vessel from failed armada of 80 warriors sunk as ritual offering in Danish bog after attack on Als island, predating Viking era by millennia.
- A new study in PLOS One uses advanced tech like gas chromatography and X-ray tomography to solve a 100-year origin mystery.
- Future DNA analysis from fingerprint could reveal crew genetics, advancing understanding of early Nordic strength and ingenuity.
Hjortspring Boat: Scandinavia’s Ancient War Vessel
Lund University archaeologists led by Mikael Fauvelle analyzed unstudied caulking from the Hjortspring boat, Scandinavia’s oldest known wooden plank vessel from the pre-Roman Iron Age. Discovered in a Danish bog on Als island in the 1880s, the boat dates to 381–161 BCE via first direct radiocarbon testing. Excavated in 1920–1922 by Gustav Rosenberg, about 40% was recovered and now displays at the National Museum of Denmark since 1937. The 19-meter craft carried ~80 warriors in a raid across open seas.

Baltic Origins Confirmed by Chemical Breakthrough
Gas chromatography-mass spectrometry on the caulking—animal fat mixed with pine pitch—showed pine resin absent in local Danish forests but abundant on eastern Baltic coasts. This evidence pinpoints the boat’s construction hundreds of kilometers away, indicating premeditated logistics for warfare. X-ray tomography revealed a partial human fingerprint pressed into the material during sealing, modeled in 3D but unidentified for sex or individual. Weapons and shields found aboard were generic, but chemistry resolved the century-old origin debate.
Raid Context and Ritual Sinking
The boat participated in an armada of at least four vessels attacking Als island, a strategic southern Danish coastal site. Defenders repelled ~80 warriors and ritually sank the captured craft in Hjortspring bog as a victory offering to the gods, along with enemy gear. Bog preservation enabled modern recovery. Similar Nordic Iron Age bog deposits of foe weapons reflect cultural practices honoring divine aid. This event highlights early Scandinavian maritime prowess predating known complexity.
Expert Insights and Future Discoveries
Mikael Fauvelle states the crew traveled hundreds of kilometers by sea, mirroring Viking raiding patterns and demonstrating “substantial planning” in Iron Age societies. The Lund University team calls the fingerprint “extremely unusual,” a tangible connection to ancient people. They plan ancient DNA extraction from the tar and fingerprint, plus tree-ring analysis of planks, to uncover genetic origins. Non-destructive methods advance archaeology, inspiring reexamination of bog artifacts for hidden clues.
Short-term, the February 16, 2026, PLOS One study boosts museum tourism and Iron Age interest. Long-term, it rewrites prehistory, portraying Scandinavians as sophisticated maritime raiders millennia before Vikings, reinforcing narratives of enduring Nordic resilience and innovation.
