Barber and Goode said the fabrics found with the mummies (In the Urumchi area) compare exactly with the fabrics from the famous Celtic sites at Hallstadt, Austria. They are alike in style, material and Manufacturing technique although they are 1,000 years and 4,000 miles apart in time/distance.
The oldest paper ever found came from this site and the extinct (Indo-European) Tocharian language was written on it. Tocharian is most similar to Celtic than other Indo-European languages.
