Thanks for the book title. I'll look for it. I'm reading, "A Traveler's History of Mexico," (Kenneth Pearce)right now, and seeing what the 'conventionals' have to say about the Olmecs, et al. Many paths cross here, surprisingly. But then, maybe not surprisingly.
Bronze, eh? That may show a connection between Lake Titicaca and Sumer as well, considering the technology that is needed to process tin. Fact is, if I remember correctly, bronze was also used in some of those ancient and monstrous stone structures in the Americas to hold them together in case of earthquakes.
Regarding the Olmecs and 'bearded ones,' there is a question of whether or not they arrived here together or converged here from separate locations. Some of the carvings appear to show the 'bearded ones' being tortured, and they may have been a slave class at some point. I'll read further.
Closer to the topic, if the 'bearded ones' were actually remnants from Israel, migrating to northern Mexico, it may point to a probability that there may be a semitic tie between some American Indian tribes and the jews. --------------------------------------------------------------------------------
