"The Devil is in the Details"
I sat on the fence about what I believed about the authenticity of the maps for about two years believing "The Devil could be in the Details", before deciding that I believed, they were authentic maps to something of value.
I know other people who came to the opposite conclusion, the first time they looked at them, and saw misspelled words on them.
As far as the "Details" are concerned... We will more than likely never really know them. There are too many conflicting stories already in circulation, which the sources of, are already dead and gone. There are no living witnesses left to cross examine. It all comes down to who each person considers to be the most reliable source.
Unless of course... You understand what the maps themselves testify to.
