Ancient Metal Working
I think this was posted here once before, but it's probably worth a
revisit. http://www.economist.com/displaystory.cfm?story_id=1337165#top -- __ Pete Snell Royal Military College Kingston Ontario The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

Interesting, however the assumptions by Mr Wright may be incorrect. I
believe it's commonly understood in modern astronomy the first sighting of Mercury was in 1610 by Galileo. This belief, if true, would make the use of the device in question to predict the orbit of Mercury 1500 years earlier, unlikely. It seems Mr.Wright may have misinterpreted his facts. dennis in nca |

Their archeologists and scientists announce to the world that it proves that the telephone had been invented and used in Russia 1000 years ago. The Americans dig 200 meters below New York City and discover some strands of glass which they claim proves that fiber optic data transmission had been invented and used in North America nearly 2000 years ago. The Israelis dig 300 meters below Jerusalem and find.......absolutely nothing. Their conclusion? Wireless voice and data links must have already been standard equipment there over 3,000 years ago.

Mercury (aka Hermes) was well-known to the ancient world, albeit not
readily visible (part of the reason for Hermes' association with thieves & trickery). rigger wrote: Interesting, however the assumptions by Mr Wright may be incorrect.
