While most of us learned that the wheel was invented around 3500 BCE for transportation, a groundbreaking discovery in Israel suggests we need to roll back our understanding of rotational technology by several thousand years. Researchers have unearthed over 100 perforated stone discs from a 12,000-year-old village that may represent humanity’s first experiments with wheel-like objects – not for moving carts or chariots, but for spinning thread.
The archaeological site of Nahal Ein-Gev II, located near the Sea of Galilee in Israel, has yielded an extraordinary collection of 113 limestone pebbles, each carefully drilled through the center. While such perforated stones are not uncommon in ancient sites, this collection is special because of its age, quantity, and the careful way the holes were made. These weren’t just random rocks with holes – they appeared to be carefully selected and modified tools that served a specific purpose.
Think of them as prehistoric fidget spinners but with a practical application. The researchers believe these perforated stones served as spindle whorls – weighted discs that, when attached to a wooden stick, helped transform plant or animal fibers into thread through spinning. It’s similar to how a modern spinning wheel works, just more primitive and portable.
The research team, led by Talia Yashuv and Leore Grosman from the Hebrew University of Jerusalem, used cutting-edge 3D scanning technology to analyze these ancient artifacts in unprecedented detail. They discovered that despite their seemingly simple appearance, these tools showed remarkable sophistication in their design and creation.
The stones weren’t just randomly selected – most were made from soft limestone, weighed between 1-34 grams (with most falling between 2-15 grams), and had holes drilled precisely through their centers. This central positioning was crucial for the spinning process to work effectively, much like how a modern fidget spinner needs perfect balance to rotate smoothly.
What’s particularly fascinating is how these holes were created. In 95% of the stones, the holes were drilled from both sides to meet in the middle – a more complex but more effective technique than drilling straight through. This bi-directional drilling created a distinctive hourglass-shaped hole that, as experimental archaeology would later prove, actually helped secure the wooden spindle in place.
This study, published in PLOS ONE, challenges our understanding of when humans first began experimenting with rotational technology. While the wheel-and-axle system is commonly associated with transportation in the Bronze Age (around 5,000 years ago), these spindle whorls show that humans were already manipulating rotational motion for practical purposes thousands of years earlier.
