The Newark Holy Stones refer to a set of artifacts allegedly discovered by David Wyrick in 1860 within a cluster of ancient Indian burial mounds near Newark, Ohio, now generally believed to be a hoax. The set consists of the Keystone, a stone bowl, and the Decalogue with its sandstone box. They can be viewed at the Johnson-Humrickhouse Museum in Coshocton, Ohio. The site where the objects were found is known as The Newark Earthworks, one of the biggest collections from an ancient American Indian culture known as the Hopewell that existed from approximately 100 BC to AD 500.
