Kudos to Professor Thomas Levy of UC-San Diego for his fabulous archaeological dig, results of which have just been published in the British journal, Antiquity.
Judy Siegel, in her excellent article in the February 22 Jerusalem Post, tells the story succinctly. Most contemporary scholars had been denying ("on the basis of no physical evidence" in Siegel's felicitous phrase) the Biblical account that the state of Edom existed in the days of David and Solomon and interacted with the Jews (then called Hebrews or Israelites) in Israel.
In past years, archaeologists had avoided digging in this area of modern Jordan's highland zone because of "the logistical difficulties of working in the extremely dry and hot region". In other words, they preferred to look for the wallet under the lamppost because the light was better.
Professor Levy's dig, conducted in 2002 and funded by the university, with a grant from the C. Paul Johnson Family Foundation, found evidence of two major phases of copper production. High precision radiocarbon dating tells them that it dates back to the 11th or 12th century BCE, a century or two before David and Solomon.
Additionally, they dug up evidence of massive fortifications and industrial-scale metal production, as well as over a hundred building complexes. All we can do is chuckle, my friends, and perhaps sigh as well. The truth is always there, hiding in plain sight.
