A small copper-alloy object, excavated nearly a century ago from a predynastic cemetery at Badari in Upper Egypt, has been re-identified as the world's oldest known Egyptian bow drill. Dating to the late 4th millennium BCE, the tool pushes back the earliest evidence for this technology in Egypt by about 2,000 years, revealing that Egyptian craftspeople mastered efficient rotary drilling much earlier than previously thought.
The discovery, made by researchers from Newcastle University and the Academy of Fine Arts Vienna, demonstrates how modern analytical techniques can unlock new secrets from long-held museum collections. Beyond its technological significance, the tool's unusual metal composition suggests the existence of extensive long-distance trade networks or unknown local ore sources in ancient Egypt, offering fresh insights into early craftsmanship and economic connections.
