Adam’s Calendar

Adam’s Calendar is controversially suggested to be the oldest man-made structure in the world.  Sometimes referred to as “African Stonehenge”, it predates both Stonehenge and the Great Pyramid of Giza by tens of thousands of years.  Located in Mpumalanga, South Africa it is a standing stone circle about 30 meters in diameter and has been estimated by some accounts to be more than 75,000 years old. Various astronomical alignments have been identified at the site and it is possibly the only example of a completely functional, mostly intact megalithic stone calendar in the world.

Scattered throughout the mountains of South Africa are thousands of stone circle ruins.  The first estimates of the number of these ruins was made in 1891 by English explorer Theodore Bent.  He estimated there were about 4,000 in this area of the world.  By 1974 the estimate had risen to 20,000.  Today, researcher and authority on the subject, Michael Tellinger, has estimated the number of ancient stone ruins to be 100,000 or possibly much higher.  Some of these “stone circles” have no doors or entrances while most are connected by an expansive network of channels that are often misinterpreted as “roads” by some historians.  This connected grid of circular ruins are immersed in a seemingly never-ending expanse of ancient agricultural terraces surrounding the structures.  Adam’s Calendar is considered to be the most famous among these ruins.

The site is aptly named Adam’s Calendar because the stones are placed to track the movement of the sun, which casts shadows on the rock.  It still works perfectly as a calendar today by following the shadow of the setting sun, which is cast by the taller central monolith onto the flat stone beside it.  This remarkable calendar was originally a large circular stone structure resembling Stonehenge and in the center of the ‘circle’ are two upright stones which are said to have been carved.  Its original shape is still clearly visible from satellite images.  The stones are all dolomite, weighing up to 5 tons each, and are said to have been transported from a distant site.  It should be noted that the area surrounding Adam’s Calendar is extremely rich in gold.  Several mining shafts have been reported in the area with one of the richest working mines in the world today being the Sheba Gold Mine, located in Mpumalanga.  Not only did the rich gold reefs attract attention in the 1880’s, but the early evidence of historic civilizations mining for minerals were described in writings by the early Europeans.

The latest and most interesting discovery of the stone circles and Adam’s Calendar is the sound frequencies of the rock formations from the earth below them.  With modern technology, Tellinger and scientists have been able to detect and measure sound frequencies with acoustic properties made from the earth inside the circles which conduct electricity.  These sound frequencies of the earth under the stones are shaped as flowers of sacred geometry as they surface to the ground.

There is still much about Adam’s calendar that is yet to be understood, including who built them, what their civilization was like, and how they constructed it with such precise measurements. Perhaps in time, more research will piece together this prehistoric mystery.
