Deep inside the borders of what is now Ohio sits a complex of ancient earthworks so precisely aligned with the rise and set of the moon that modern surveying equipment could not do better. And this summer, lots of public events means you can enjoy and marvel as the ancients must have done.
Built two millennia ago, one
basket-load of dirt at a time, the biggest enclosures would swallow up several
football fields; Stonehenge could be tucked into a tiny corner of one of these gigantic
shapes. Newark and other Ohio earthworks--Serpent Mound, in Peebles; Fort
Ancient, in Lebanon; and Hopewell Culture
National Historical Park/Mound City, in Chillicothe--are being considered for
UNESCO’s list of World Heritage Sites. “The Newark Earthworks are
proof of our ancestors’ genius,” says Carol Welsh, Sisseton-Wahpeton Oyate and director
of the Native American Indian Center of Central Ohio (NAICCO), in Columbus.
What the earthworks’ builders
called themselves is not known; archaeologists refer to them as “the Hopewell
culture,” after the owner of a farm where artifacts were found during the 19th century. People often assume that mounds involve
burials. “This is not necessarily so,” says Welsh. “Some did, but most appear to have
been places of celebration, where folks came together to pray and honor the
gifts of the Earth.”
Bradley Lepper, Ohio
Historical Society curator of archaeology, is a prominent authority on the Newark
complex, which he has termed a “ceremonial landscape of unprecedented scope.” Community historian and Ohio Archaeology Council member
Jeff Gill compares Newark’s multiple celestial alignments and immensely
complicated design—melding man-made creations with natural features of the
surrounding, hill-ringed river valley—to Egypt’s Valley of the Kings. Astronomer,
physicist and Earlham College professor Ray Hively, who worked with Earlham
colleague Robert Horn to plot the Newark site’s moonrise and moonset
alignments, found that its lunar alignments precisely encode the orb’s complex
cycle,
with moonrises and moonsets rotating north and south over an 18.61-year cycle.
It’s clear the ancients were virtuosic geometers and astronomers.
Lepper describes the research on their sophisticated mathematics in a 2010 paper,
The Ceremonial Landscape of the Newark
Earthworks and the Raccoon Creek Valley. In one of many examples Lepper provides,
he notes that the circumference of one of the massive Newark circles is equal
to the perimeter of a nearby square. The diameter of another circle appears to have
been used as a gigantic measuring stick for laying out the site.
Further, the construction of squares and circles with equal
areas solved a primordial math problem—squaring the circle—that fascinated and flummoxed mathematicians as far back
as the fifth century
B.C. in
Ancient Greece. For millennia scholars have considered solving this problem to
be so difficult that the phrase “squaring the circle” has come to mean doing
the impossible.
Equally astonishing, the geometry and the lunar alignments of
the Newark Earthworks appear to coordinate with those in other complexes many
miles away, according to Chaatsmith. Lepper has shown that one set of parallel
walls exiting the Newark site point directly to the collection of burial mounds
now protected as Hopewell Culture National
Historical Park, in Chillicothe, 60 miles away (shown below). The Newark walls may demark a
ceremonial passage to the Chillicothe complex, says
Lepper, though centuries of development and agricultural plowing have
destroyed much of the evidence needed to prove that.
Though many of Ohio’s
earthworks and mounds have been obscured or taken to the ground by farms and
towns, their energy endures. During a recent visit, a hawk—the bird revered by
the ancients—surfed the thermals above a mound outside Chillicothe that had
been plowed flat. The bird appeared to be guarding the site 2,000 years after the
its builders had walked on.
Summer in the Earthworks:
2012 Events
This summer, you can enjoy the Ohio places during earthworks-themed concerts, lectures, night-sky events,
children’s programming and more throughout the verdant, mostly rural south-central part of the state.

Fort Ancient, go to ancientohiotrail.org,
and click on “Events.” “I love being able to share
the earthworks with Native and non-Native folks,” says Carol Welsh, of NAICCO. “They reinforce the good of being Indian.”
