Expect to read about this in the next Dan Brown shine-a-flashlight-under-your-chin tin foil hat novel (actually, no: don't expect to read about this, because that might require some actual research on the part of the author). Some of the greatest wonders of the ancient world - Easter Island, Nazca, Ollantaytambo, Paratoari, Tassili n'Ajjer and Giza - are all aligned on a single, great, invisible circle.
According to the mind-blowing site where I found this, "additional ancient sites that are located within one tenth of one degree of this great circle include Petra; Persepolis; Khajuraho; Pyay, Sukhothai and Anatom Island."
But there's more.
"Near Ollantaytambo, Machu Picchu and Cusco are within one quarter of a degree. The Oracle at Siwa in the western Egyptian desert is within one quarter of a degree. In the Indus Valley, Mohenjo-daro and Ganweriwala are within one quarter of a degree. The ancient Sumerian city of Ur and Angkor temples in Cambodia and Thailand are within one degree of the great circle. The Angkor temple at Preah Vihear is within one quarter of a degree."
And the list goes on, making both my mind and my link button explode in giddy amazement.
"This circle crosses over the source and the mouth of the Amazon, the dividing line between upper and lower Egypt, the mouth of the Tigris-Euphrates, the Indus River and the Bay of Bengal near the mouth of the Ganges. The circle also crosses over a number of areas of the world that are largely unexplored, including the Sahara Desert, the Brazilian Rainforest, the highlands of New Guinea, and underwater areas of the North Atlantic Ocean, the South Pacific Ocean and the South China Sea."
Spooky.
