The inspiring story of how two intrepid college professors revealed the lunar alignments and ancient engineering genius behind the Hopewell Ceremonial Earthworks. How did people two millennia ago achieve the stunning architectural and scientific accomplishment that in 2023 became Ohio’s only UNESCO World Heritage Site? In Where the Moon Stands Still, James W. Graham recounts the inspiring true story of two small-town college professors who, without funds or training in archaeology, helped unlock secrets behind an ancient monumental work of land art—the Hopewell Ceremonial Earthworks—all but hidden in plain sight on a local golf course. Ever since the arrival of Europeans, thousands of Native earthworks east of the Mississippi were neglected, vandalized, bulldozed, and plundered. Their origins and purposes baffled scholars. How did ancient people build monuments of such grand scale and geometric sophistication? Why? Crucial answers emerged in the 1980s when philosopher Bob Horn and astronomer Ray Hively, driven by curiosity and a tireless devotion to truth-seeking, made a decades-long effort to conquer the skepticism of experts and unmask the ??astronomical genius behind the Indigenous earthworks. As he recounts Hively and Horn’s investigation, Graham refutes exploitative mythical interpretations and explains the history around these earthworks and of US treatment of its Indigenous people, including the long quest for tribes to regain authority over stories, ancestors, and places. Where the Moon Stands Still signals a global reawakening to the greatness of Indigenous achievement in America’s heartland.
