In 1909, a shadowy syndicate of treasure hunters set out from England on an expedition to Jerusalem. Their goal was nothing less than to find and take possession of the Ark of the Covenant—the legendary gold-covered chest in which the shattered remains of the Ten Commandments were said to be stored. Some of the group were fascinated by the mysterious quest itself; some hoped to become rich beyond their wildest dreams.
At the head of the expedition was Monty Parker, the son of an English earl and a veteran of the First Boer War. But the group’s ace-in-the-hole was Valter Juvelius, an eccentric Finnish scholar who claimed to have uncovered a code—in the Old Testament’s Book of Ezekiel, based on the number seven—that would lead them to the Ark. This may sound far-fetched today, but the period between the mid-19th and early-20th centuries was a time of fevered archaeological exploration marked by improbable discoveries across the remnants of the ancient world. Finds of the time included the Cuerdale Hoard in England, the palace of Knossos in Crete and Paleolithic cave art in Altamira, Spain.
As Brad Ricca recounts in “True Raiders: The Untold Story of the 1909 Expedition to Find the Legendary Ark ofthe Covenant,” Parker’s expedition encountered problems from the beginning. There were the seasonal rains. And when the locals in Jerusalem learned that the treasure hunters meant to dig under the revered Dome of the Rock, they reacted with violence. But the biggest obstacle was the vagueness of the cipher itself, which, according to Juvelius, was intended both to reveal and obscure the whereabouts of the Ark.
