Octagon Earthworks’ alignment with moon likely is no accident
The Octagon Earthworks in Newark is one remnant of the Newark
Earthworks, recently listed by The Dispatch as one of the Seven Wonders
of Ohio. Earlham College professors Ray Hively and Robert Horn demonstrated in 1982 that the walls of this 2,000-yearold circle and octagon were aligned to the points on the horizon, marking the limits of the rising and setting of the moon during an 18.6-year cycle.
