Inspired by the Bible's account of the splendor of his temples and palaces adorned in glittering gold and copper, countless treasure-seekers have set off in search of King Solomon's mines. They have trekked through burning deserts and scaled the forbidding mountains of Africa and the Levant. Yet to date, the evidence that's been claimed to support the existence of Solomon and other early kingdoms in the Bible has been highly controversial. In fact, there is so little physical evidence of the kings who ruled Israel and Edom that many contend that they are no more real than King Arthur. During the summer of 2010, NOVA and National Geographic embarked on two groundbreaking expeditions to expose new clues buried in the pockmarked desert of Jordan: the ancient remnants of a mass industrial-scale copper mine and a 3,000-year-old message from the past with the words "slave," "king" and "judge." These cutting-edge investigations illuminate the legend of Solomon and reveal the source of the great wealth that powered the first mighty Biblical kingdoms.
