The English word "sprang" is of Swedish origin. It may have spread southward toward the Mediterranean during the Iron Age or possibly the late Bronze Age. The earliest surviving example of sprang is a hair net, c. 1400 B.C., that was recovered from a bog in Denmark. Most archaeological finds of sprang fabric come from the later classical era and early Dark Ages: locations include Norway (third to fifth centuries A.D.), Switzerland, Egypt (possibly twenty-second dynasty, also early Coptic), and various Roman sites. Use of sprang has also been conjectured from archaeological recoveries of ancient looms and from depictions in period artwork.
