Oldest Astronomical Megalith Alignment Discovered In Egypt By Science Team

An assembly of huge stone slabs found in Egypt's Sahara Desert that date from about 6,500 years to 6,000 years ago has been confirmed by scientists to be the oldest known astronomical alignment of megaliths in the world.

Known as Nabta, the site consists of a stone circle, a series of flat, tomb-like stone structures and five lines of standing and toppled megaliths. Located west of the Nile River in southern Egypt, Nabta predates Stonehenge and similar prehistoric sites around the world by about 1,000 years, said University of Colorado at Boulder astronomy Professor J. McKim Malville.

The Nabta site was discovered several years ago by a team led by Southern Methodist University anthropology Professor Fred Wendorf. A 1997 GPS satellite survey by Malville, Wendorf, Ali A Mazar of the Egyptian Geological Survey and Romauld Schild of the Polish Academy of Sciences confirmed one of the megalith lines was oriented in an east-west direction.

"This is the oldest documented astronomical alignment of megaliths in the world," said Malville. "A lot of effort went into the construction of a purely symbolic and ceremonial site." The stone slabs, some of which are nine feet high, were dragged to the site from a mile or more distant, he said.

The ruins lie on the shoreline of an ancient lake that began filling with water about 11,000 years ago when the African summer monsoon shifted north. It was used by nomads until about 4,800 years ago, when the monsoon moved southwest and the area again became "hyperarid and uninhabitable."

Five megalithic alignments at Nabta radiate outward from a central collection of megalithic structures. Beneath one structure was a sculptured rock resembling a cow standing upright, Malville said. The team also excavated several cattle burials at Nabta, including an articulated skeleton buried in a roofed, clay-lined chamber.

The 12-foot-in-diameter stone circle contains four sets of upright slabs. Two sets were aligned in a north-south direction while the second pair of slabs provides a line of sight toward the summer solstice horizon
