Woodhenge, Cahokia

Woodhenge, Cahokia

Although, there are many who doubt that the Medicine Wheel in Bighorn Mountain, Wyoming is an astronomical calendar, 1200 miles east in the ancient metropolis of Cahokia, the “Woodhenge” structures are generally accepted as astronomical calendars.   The structures are simple, a center post surrounded by differing numbers of posts in wide circles.  The number of posts in the circumference seemed to grow in number with each rebuilding of the structures.  Here is a quote by William Iseminger, assistant site manager in charge of exhibits, interpretations and public relations at Cahokia for the Illinois Historic Preservation Agency, from his book “Cahokia Mounds, America’s First City”:

Crestone EquinoxTwice a year, a day comes along where the length of daylight equals the length of darkness.  Today we call that day the “equinox”.  We recognize the vernal equinox as the first day of spring and the autumnal equinox as the first day of fall.  These two days have always been important indicators for man since even ancient times.

Sangre de Cristo Calendar

Before Europeans came to America, Native Americans did not have bankers, insurance agents, or real estate agents so where did they get their calendars?  How did they know when spring or fall arrived?  They had someone more important to them than our bankers or agents are to us, they had astronomers.

Copper Ornaments made at Cahokia
found at Wulfing, Etowah, and Sprio sites
Last week, we were introduced to the forgotten city of Cahokia, near St. Louis, the largest Native American city in North America.  It flourished around 1300 A. D.  Since the buildings and structures were built of wood, only the enormous mounds that the structures were built on, and the round burial mounds remain.
Cahokia was clearly the center for trade east of the Mississippi river and was probably the center of power during its heyday.  It was also the center for the manufacture of copper goods.  Although Mound 34 had been discovered in 1950 by archaeologist Greg Perino, the work done from 2002 to 2010 has revealed that it was the site of a one-of-a-kind copper workshop.

Around 1050 A. D., there existed a grand city nestled in the Mississippi valley where St. Louis is today.  We call this site “Cahokia” because the Cahokia tribe once lived nearby.  But the Cahokia referred to the ancient city as belonging to a forgotten tribe that lived before them.

Monk’s Mound

By any measure, this city was magnificent.  It covered over 4,000 acres, and had a population estimated between 10-20,000 within the city proper and 70,000 if you count the suburbs.  Grand temples and houses were built atop enormous platform mounds.   There were approximately 120 of these platform mounds of

Medicine Wheel

Stonehenge, in England, has long been a source of fascination for most of us.  It is credited as being an archaeoastronomical site – an ancient site for astronomical observations.  I recently posted articles on “Medicine Wheels” that have a similar purpose.  This week, I want to write about circles built by the Hopewell culture that also suggest astronomical purposes.  Nicknamed “Woodhenge” because of their similarity to Stonehenge and Woodhenge in England, these sites are east of the Mississippi River and were built by the Hopewell Indians living from around 200 A.D. to around 1,500 A. D.
