Stone Age Rope and Thread: Archaeology's Invisible Technology

Archaeologists are piecing together a largely invisible chapter of prehistory: the fiber technologies that shaped early human life. Because plant-based materials decay quickly, they rarely survive in the archaeological record, and researchers have long relied on stone tools and bone artifacts instead.

A striking clue came from Hohle Fels cave in southern Germany. In 2015, researchers recovered an ivory artifact, called a lochstab, that is more than 35,000 years old. Its four small holes were lined with carved spiral grooves, which led Nicholas Conard of the University of Tübingen to suspect it was used to twist fibers into cord. In experiments, his team threaded cattail fibers through a replica and produced 16 feet of thick, strong rope in ten minutes.

The finding highlights a bigger problem. The people of Hohle Fels must have made large amounts of rope, yet none has survived. Only the durable ivory tool remains, pointing to a production system that leaves little direct trace.

Experts say this bias skews our understanding of the past. Paleoanthropologist Emma Finestone of the Cleveland Museum of Natural History notes that researchers focus on what preserves well. Bruce Hardy of Kenyon College adds that 90 percent or more of prehistoric daily activity may be missing from the record, much of it involving technologies no one thinks about today.

The oldest surviving human-made fiber, a six-millimeter piece of string, offers a rare glimpse of this hidden world. By reconstructing these soft technologies, archaeologists hope to better understand how early humans survived and lived.
