Discovering Petra's Hidden Tomb Under the Treasury

A group of researchers, including experts from the University of St Andrews, has uncovered a hidden tomb beneath the Treasury Building at Petra, one of the new seven wonders of the world. This important discovery includes the remains of 12 ancient skeletons and is showcased in a new Discovery Channel documentary titled "Excavation Unknown," featuring adventurer Josh Gates.

The Treasury, which was carved by the Nabatean Kingdom around 2,000 years ago, is renowned as the setting for the Holy Grail in "Indiana Jones and the Last Crusade," but its actual purpose remains unclear. The research team employed remote sensing technology, including ground penetrating radar, to explore the area.

Professor Richard Bates explained that the survey's primary goal was to evaluate the condition of the areas around the courtyard and plaza in preparation for potential flood management strategies. After detecting possible underground chambers, the team worked with the Department of Antiquities and ACOR to formulate an excavation plan, which ultimately revealed the tomb with its ancient remains preserved.

This discovery holds international importance, as very few complete Nabataean burials have been recovered from Petra. The findings, including the burials and their associated artifacts, are expected to deepen our understanding of the Nabataeans and the historical context of Petra.

Dr. Tim Kinnaird contributed by dating the sediment around the burials, suggesting that the tomb was likely constructed as a mausoleum for Aretas IV Philopatris at the beginning of the first century AD. He highlighted the significance of obtaining definitive dates for the Treasury's construction.

During the excavation, one skeleton was discovered holding a ceramic vessel that closely resembled a chalice, prompting excitement from Gates due to its likeness to the Holy Grail depicted in the film. Detailed analysis identified the vessel as the upper portion of a broken jug, likely dating back to the first century BC.

Professor Bates expressed his appreciation for the chance to investigate such a historic location, emphasizing that the extent of the discovery will likely provide valuable insights into both the Treasury and the Nabatean society. Pearce Paul Creasman, Executive Director of ACOR, noted the numerous questions still unanswered about the Treasury, suggesting that this excavation could significantly enhance our knowledge of the Nabataeans, with support from the Jordanian government.
