It's not every day that science and the Bible come together to tell a piece of history. Modern dating methods have determined that huge mines in Jordan are 3000 years old, supporting the idea that they were the Biblical mines of Edom ruled by King David and his son Solomon.
"The results are very, very consistent and leave no doubt as to the period [during which the mines were active]," says Tom Higham of the University of Oxford.
Higham and colleagues dated samples of charcoal used to smelt copper ore from the site.
The age of the Khirbat en-Nahas mines in the Faynan district of southern Jordan has been controversial for decades. The new evidence suggests that the site, one of the oldest, largest and best preserved mines in the world, really is the one mentioned in the Bible.
