Do you have links to these pictures of light bulbs? I'm intrigued. I've heard of the baghdad battery, and there was another one found in India if I'm not mistaken.

And the romans destroyed a bunch because they had different beliefs, but there are theories that they were destroying lost knowledge. A lot of the primitive pyramids that have gimmicks regarding solstices and equinoxes (such as the Temple of Kulkulkan at Chichen Itza, or the Magisters House at Tulum) do crazy things like glow or make shapes on the pyramid so that the tribal shaman could announce/ predict harvests.

Hmm, Bolivia. I havent heard of the site but I think I'll have to get down there over the summer when me and my friend head out on another south american trek, we're planning on hitting up Tikal and Machu Pichu at least since we missed them on our last venture in January. Fuck jobs, just save enough to travel to poor latin american countries and live like Indiana Jones.
