Global warming is allowing archeologists to learn more about human history, as textile fragments have been recovered from melting glaciers.
One particularly rare item is an intact tunic found on the Norwegian Lendbreen glacier. Researcher Lise Bender Jørgensen told Discovery News about its significance:
"It is a very rare item. Complete garments from early first millennium A.D. Europe can be counted on the fingers of one hand."
Carbon dating indicates that the wool garment was made between 230 and 390 C.E. It's woven in a diamond-shaped pattern that has been found in other garments from Northern Europe.
Jørgensen and Marianne Vedeler have written about the finding in the September issue of the academic journal Antiquity. The garment likely belonged to a male hunter, Vedeler told the BBC:
"The Lendbreen tunic is a first glimpse of the kind of warm clothing used by hunters frequenting the ice patches of Scandinavia in pursuit of reindeer. It had no buttons or fastenings, but was simply drawn over the head like a sweater."
