Flynn Carsen (Noah Wyle) and his guardian Nicole Noone (Sonya Walger) parachute into the Amazon jungle. They're soon surrounded by Amazon Indians with bows and arrows.
1) The dance conveys the stereotypical idea that the Indians have no real culture. All they have is a primitive physical ritual like something an animal would do. A strutting peacock, perhaps.
2) Most tribal dances are about propitiating the gods and spirits. I've never heard of a tribe's having a "mating dance."
3) It's doubtful Indians would do something as intimate as a mating dance before a pair of strangers they'd just met.
1) The Toltecs didn't conquer Chichén Itzá. Archaeologists aren't sure whether another Maya city-state conquered it or the residents simply abandoned it.
2) Why would Maya priests flee a couple thousand miles through countless jungles and other obstacles to another continent? Why not join another Maya city-state nearby or start their own?
3) The Maya didn't have wheeled carts or beasts of burdens. Each priest would've had to carry the heavy gold himself over the entire trek.
4) Traveling that far on foot with a valuable treasure would be like inviting the hundreds of tribes along the way to rob and kill you.
The writers may have been thinking of the precession of the equinoxes, which happens about every 26,000 years. New Agers claim the Maya knew about this, but it probably isn't true:
It's absurd that all these mechanisms are in perfect working order after 700 years of neglect. And the "death chamber" and subsequent traps imply that the Maya were as deadly as the aforementioned Amazon "headhunters." Every Indian in The Librarian is implicitly a killer.
Flynn gives the size of the chamber in the Mayan temple as "300 quahuitls by 20 quahuitls." But the quahuitl was an Aztec unit of measurement, and was not used by the Maya.
Flynn says that the chamber in the Mayan temple is 300 quahuitls long. A quahuitl is approximately 2.5 meters, so 300 quahuitls would be 750 meters, or nearly half a mile. The chamber he and the others are in is large, but not that large.
Maybe so, but the Maya mirrors were polished stone, not glass. I don't think they could produce optical illusions. And in one shot, we see Flynn from beneath the mirror, which implies it's transparent.
Down the Corridor of Death
The Librarian: Quest for the Spear isn't quite as ridiculous as National Treasure: Book of Secrets, but it's in the same ballpark. Compared to it, Raiders of Lost Ark look like a masterpiece of realism and authenticity.
And the stupid thing is that the writers obviously did some research into Native culture and history. If they had the facts in front of them, how and why did they garble them so badly? Why not make a tiny additional effort to get them right?
It's as though 12-year-olds mixed and matched an encyclopedia's entries. It's stupid, stereotypical writing that ruins the movie for anyone with more than a grade-school knowledge of science. What a pathetic waste.
