Can anyone tell me if they have heard of Mercury pools left in tombs? I find it interesting they found some. This must have served some theosophical and esoteric meaning. Otherwise, I guess it is just a cultural religious practice which can result from any religious myth. But that should have a root theosophical cause, shouldn't it?

News Excerpt:
" Archaeologists excavating the third largest pyramid in the ancient Mesoamerican city of Teotihuacan have come across a large reservoir of liquid mercury in a newly discovered chamber."
