Just happened upon this article today, about the Georgia Guidestones. In light of recent posts on sacred stones, the apocalypse and even the cultural/political conflicts of our times, it is especially relevant to our discussion. Sample quote:
"The four vertical slabs that dominate the Guidestones are inscribed back and front with Christian's 10 principles, each side in a different modern language. The capstone is inscribed in the alphabets of early human civilizations -- Egyptian hieroglyphics, Babylonian cuneiform, Sanskrit and classical Greek.
The center column has a slot through which the transit of the sun throughout the seasons can be observed, while a hole higher up focuses on Polaris, the north star. Another hole in the capstone focuses a beam of sunlight onto the central pillar at noon. Those features would allow the survivors of Christian's feared apocalypse to reproduce three of the basic tools of civilization: the calendar, clock and compass."
Can't believe this is the first we've heard of it! Actually, though, this article from Wired is much more intriguing. A mysterious stranger obsessed with secrecy turns up and says he and his group had wanted to do this for 20 years; a local minister predicts it will become a magnet for occult groups--and is right; the sandblaster who made the inscriptions reported hearing "strange music and disjointed voices"; Freemasons are intimately involved etc. etc.
