Oldest Indigo-Dyed Fabric Ever Is Discovered in Peru

The oldest indigo-dyed fabric ever found has been discovered in Peru, pushing back the use of this blue coloring to at least 6,200 years ago. The discovery in Peru, however, shines a spotlight on the Americas, which are less-discussed in terms of firsts, said study researcher Jeffrey Splitstoser, an archaeologist and textile expert at The George Washington University. The dyed fabric pieces are small scraps made of woven cotton.
