Finding ancient well-persevered clothes is not something that happens every day. This is why this particular 1,700-year-old tunic is so special. It is Norway’s oldest piece of clothing and despite being hidden beneath the snow for so many years, it’s still very well-preserved.

“It’s very rarely that we find well-preserved clothing from prehistoric times,” explains Marianne Vedeler, professor at the Museum of Cultural History at the University of Oslo to Yngve Vogt of the Apollan Research Magazine. “Only a handful of clothing like this has been found in Europe.”

With climate change melting glaciers like the Lendbreen at unprecedented rates, hundreds of artifacts emerge from the ice every summer, presenting clues to piecing together the lives of communities dependent on glaciers and the interconnected relationship between the humans and the rest of the environment.

The tunic was unearthed when the Sun exposed the upper edges of Lendbreen Glacier at the Lomseggen mountain in Breheimen National Park in Norway.

Archaeologists and conservators are now trying to learn more about the clothing’s mysterious past. Who wore the tunic? Why was it left in the glacier? How was it made? What raw materials were used, and how time-consuming was the process?

The Lomseggen mountain, home to the Lendbreen glacier, now separates the modern villages of Lom and Skjak. Archaeologists determined that this was once a passage used during the Iron Age as a transport route for people traveling between valleys, such as Bøverdalen and Ottadalen.

Why the tunic was left behind remains a mystery. Perhaps it was left at a place where people had camped to hunt reindeer. Perhaps the hunting party had gotten caught up in a storm and died. It’s really impossible to determine, but in the realm of archaeology, textiles are difficult to preserve over time.

The Lendbreen tunic is estimated to have been made between 230 and 390 A.D. and gives archaeologists and historians a glimpse of what life would have been like 1,700 years ago. Woven from sheep’s wool, it is of a basic cut and was evidently frequently used with repaired patches on the back, indicating its extensive use 1,700 years ago.

It is also relatively short, with historians concluding it was meant for a man or boy of slender build. Overall, specialists claim the yarns and patterns in the tunic were of a standard Iron Age practice and not requiring expert knowledge to produce

However, it is evident the tunic was time-consuming to make. “In prehistory, the time spent on fiber preparation, spinning, and weaving must have varied greatly depending on differences in the raw materials and the tools used, and the knowledge and skills of the people producing the textiles,” stated the study, “It must still have been a very time-consuming task to produce a textile. This applies to everyday fabrics as well as to the most valuable ones.”

Reconstruction of the Lendbreen tunic has been a time-consuming process. It took 760 hours for handweavers to reproduce the tunic from scratch using old-fashioned techniques. They used wool from traditional breeds of sheep in western Norway that could have been used to create the yarn in the tunic.

The Lendbreen tunic will be exhibited at the Norwegian Mountain Center in Lom and the Museum of Cultural History in Oslo.
