Quite interesting - Mayan day/nights and earth periods

[Raman]

columbus was trying to get to east india, and accidentally landed on hispaniola. then various explorations were done partly with general methods (Sailing around) and partly by what local indians told them. el dorado was one of those legends that were told by indians.

yeah, that is what is written in history books...

I was referring to things like maps available that were only known to a few. But i'm tired of making wild (almost) guesses.

and countless of other stories..

But most probably spanish did not have any idea of El Dorado until they found that out once they arrived.
