Nearly a quarter-mile long as measured by the centerline of its curves, Serpent Mound is the largest prehistoric effigy of its kind in the world. It was built on a ridge above the valley of Ohio Brush Creek by an unknown people, perhaps 1,000 to 3,000 years ago.
Proving when it was built could indicate who those people were – and why they undertook an engineering feat that demonstrates a sophisticated understanding of geometry and astronomy, said William F. Romain of suburban Cleveland, an archaeo-astronomer who will lead a team of archaeologists.
“We expect to generate a new and detailed understanding of the serpent’s internal structure,” Romain wrote in seeking a permit from the Ohio Historical Society, which owns the site. “Our goal is to provide a series of graphic illustrations.”
