Ancient Structures

 Thousands of Unknown Ancient Structures seen from Space

Thousands of huge ancient structures made of stone are clearly visible from the air.
Their age is estimated to thousands of years and their purpose remains unknown.
These puzzling wheel-shapes, and straight lines, stretch all the way from Syria to Saudi Arabia.
Some call this area the Middle East's own version of the Nazca Lines.
It is only recently, with help of satellite images that archaeologists have been able to explore this region in more detail.
Since the launch of Google Earth in 2005, archeologists have begun to use the satellite imagery publicly, particularly since its gradual incorporation, beginning in 2007, of high-resolution images. 

As a result, over some Arab countries-Jordan, Syria and Lebanon particularly-the resolution of available images is now generally high enough to conduct reliable, general archeological surveys.
The Shuway-mas site south of Hayil, Saudi Arabia, which is not even mentioned in the 1998 edition of the Cambridge Illustrated History of Prehistoric Art is the home of one of the four best collections of ancient rock art in the world. Here we find, numerous ancient stone kites, mounds, and tails.

In the Harrat Khaybar region of Saudi Arabia, however, "kites" take on entirely different shapes-most notably the "square pocket" and "barbed arrow"-and the low walls of many of them show ruler-straight lines, raising new questions for archeologists.
Some of these low walls of stone-many long known to archeologists inside Saudi Arabia-are newly visible from any computer in the world. The high-resolution image swaths reveal stunningly well-preserved evidence of widespread human activity in the distant past.
In the Al-Hayit region, keyhole and pendant shapes vary in size from a few meters to dozens of meters, and they are often found arranged along "avenues" that are invisible to builders of modern highways.

Who created these structures and for what purpose?
In the 1920's when British Royal Air Force pilots flew over the northern Harrat Harrah, they were struck by the numbers and variety of archeological remains visible in that rugged, thinly populated landscape.
In Jordan, there are similar structures visible from the air. The Bedouin say the structures and walls are "the works of the Old Men".
In the barren desert landscape, hundreds of kilometres from anywhere, there are thousands upon thousands of elaborate stone wheels, measuring up to 70 metres wide and visible only from the sky.
They remained largely a secret until the 1970s when Dr David Kennedy, now a professor of classics and ancient history at the University of Western Australia, saw them in great numbers while studying old survey photographs from Jordan.
Beginning in the mid-1990s, Dr Kennedy led an aerial photography project aimed at documenting Jordanian archaeological sites.
"These structures are largely unknown," he said. "Frequently, you can't see any of these structures from the ground.
Or you can just see a jumble of boulders that don't make any sense. But you go up a small distance and they are extraordinary."
The stone circles' age is unknown. They are at least 2,000 years old, but could have been built up to 9,000 years ago.
Compared to the Peruvian desert's Nazca drawings - which date as far back as the year 400, number in the hundreds and have a maximum breadth of about 270 metres - the Middle East patterns are more numerous, bigger and much older.
"These volcanic lava fields are the last place you'd expect to find these kinds of structures," Dr Kennedy said. "The landscape is not hospitable. It looks bleak and barren. They're so unusual."
At least 3,000 structures have been found in Jordan and Dr Kennedy's recent research has documented nearly 2,000 in Saudi Arabia.
As seen, there are a huge number, variety and forms of figures in different regions. Unfortunately, there are still many unanswered questions. We do not know why they were built. Neither do we know when they were constructed or by whom....
