Quite interesting - Mayan day/nights and earth periods

And it seems the search for "El Dorado" was part of the spanish going to south america. Maps were available at that time...even many thousands of years earth was known to be a sphere. Even Plato knew of Atlantis.
So information was available at the time of Columbus.

But then, it seems those cities were never found by europeans.

spanish heard el dorado when they landed in mainland america.

yeah, that seems to be the case. The direction of the travels, etc might have been influenced by el dorado and such other possible information.

Would be interesting to know what kind of maps they had and what kind of info the pope, Columbus, etc had...
