Team discovers fabric collection dating back to Kings David and Solomonhttp://phys.org/news/2016-02-team-fabric-dating-kings-david.html
"The possession of copper was a source of great power, much as oil is today," Dr. Ben-Yosef said. "If a person had the exceptional knowledge to 'create copper,' he was considered well-versed in an extremely sophisticated technology. He would have been considered magical or supernatural, and his social status would have reflected this."
To support this "silicon valley" of copper production in the middle of the desert, food, water and textiles had to be transported long distances through the unforgiving desert climate and into the valley. The latest discovery of fabrics, many of which were made far from Timna in specialized textile workshops, provides a glimpse into the trade practices and regional economy of the day.
"We found linen, which was not produced locally. It was most likely from the Jordan Valley or Northern Israel. The majority of the fabrics were made of sheep's wool, a cloth that is seldom found in this ancient period," said TAU masters student Vanessa Workman. "This tells us how developed and sophisticated both their textile craft and trade networks must have been."
"'Nomad' does not mean 'simple,'" said Dr. Ben-Yosef. "This discovery strengthens our understanding of the Edomites as an important geopolitical presence. The fabrics are of a very high quality, with complex designs and beautiful dyes."

And, fuel to smelt the copper! They all miss that point. They used Holm Oak charcoal, and in the process turned the "wilderness" into a desert.
