Samarkand is a city in Uzbekistan (Central Asia). It is located at the foot of the Alai Mountains, at an altitude of 720 meters. To the southeast, 400 km away, are the famous Pamir Mountains.
Samarkand was known to the ancient Greeks as “Marakanda”, being famous for the fertile plain “Zarashon”, called by the Greeks “Polytimetos”. The city was founded by the Persians, and in 329 BC the fortress was conquered by Alexander the Great. Under Muslim rule, the city’s development is rapid, especially under the Persian rule of the Samanid dynasty. The Mongols under Genghis Khan destroyed the city in 1220. Under the rule of the Mongol inn Timur Lenk, Samarkand became the capital of his empire. In 1925, the city became the capital of Uzbekistan, the capital being later moved to Tashkent.
Why did I make this introduction? Because in a 1903 photograph taken in Samarkand, Uzbekistan, some archaeologists are seen standing in front of a sort of “star gate”! This gate is one of the rarest artifacts I have ever seen. It looks like something out of a SF movie or it looks like it came from another dimension!
Unfortunately, the “star gate” is no longer in any museum in the world today, but it may have been in a private collection. On the other hand, look at the characters on the edges of the gate… Similar characters can be found in the “Stargate” series ! Were the producers of this series inspired by this mysterious discovery?
Where is the artifact now? And why did they hide it?
PS On the Internet, this photo provoked some discussion. Some people think the picture is fake, that is, manipulated. But until a very clear proof that she was “photoshoped”, we must give her credit.
