This deep dive examines the Copper Scroll, officially 3Q15, a first-century artifact that has baffled linguists, historians, and treasure hunters for decades. We explore the engineering feat required to open it, the cryptic inventory inside, and the competing theories about whose fortune it records and whether any of it remains.

• How an engineer at Manchester sawed the calcified scroll into 23 strips to read text that would otherwise shatter into dust
• The robotic, formulaic inventory of 63 caches totaling tons of gold and silver, with depths, locations, and weights in talent ...
