For decades, the Grolier Codex has been one of the most controversial artifacts in Mesoamerican history.
Discovered under mysterious circumstances in the 1960s, this ancient Maya manuscript has long been dismissed as a possible forgery, its authenticity questioned by scholars and archaeologists alike.
But a new comprehensive analysis has turned the tide.
A team of researchers has now confirmed the Grolier Codex is genuine, making it the oldest known book written in the Americas.
This changes everything.
While the world has long accepted three surviving Maya codices—the Dresden, Madrid, and Paris codices—the Grolier Codex now joins their ranks, rewriting what we know about pre-Columbian manuscripts.
So why was this text dismissed for so long? And what evidence finally silenced the skeptics?
A Discovery Shrouded in Mystery
Unlike the other Maya codices, which were uncovered in the 19th century, the Grolier Codex emerged under far more suspicious circumstances.
The story goes that a group of looters stumbled upon a hidden cave in Chiapas, Mexico, where they found the codex alongside a wooden mask and a sacrificial knife—both of which were later proven authentic.
But the codex itself? Many experts weren’t so sure.
The artifact eventually made its way into the hands of Josué Sáenz, a wealthy Mexican collector, who later recounted a bizarre tale of how he acquired it.
According to Sáenz, the looters flew him to a secret location, deliberately covering the plane’s compass so he wouldn’t know where he was going.
The entire ordeal sounded more like an Indiana Jones adventure than a legitimate archaeological discovery.
Naturally, historians were skeptical. Was this just an elaborate hoax? A forgery designed to fool experts and fetch a high price on the black market?
Why Experts Dismissed the Grolier Codex
From the beginning, the Grolier Codex didn’t fit the mold.
It surfaced much later than the other Maya codices.
It wasn’t discovered by archaeologists but by looters—a major red flag.
Its artwork looked different from the established Maya style, leading many to believe it was a modern fake.
For years, scholars refused to accept it. The prevailing dogma was that the codex was too different, too suspicious, to be real.
But the latest scientific analysis just proved them wrong.
What Finally Proved It Was Real
A team led by anthropologist Stephen Houston from Brown University re-examined the codex from every angle.
Their goal? To address every criticism that had been leveled against it.
Their findings were groundbreaking.
Carbon dating confirmed the pages were from the 13th century, making it the oldest surviving Maya manuscript—predating the other codices by centuries.
The craftsmanship and iconography matched known Maya painting techniques, proving it was created by ancient scribes.
The astronomical content was incredibly accurate, detailing Venus cycles in ways that would have been impossible to forge in the 1960s—because some of this knowledge wasn’t even discovered by modern scholars until later.
As Houston put it:
“It became a kind of dogma that this was a fake. We decided to return and look at it very carefully, to check criticisms one at a time.
There can’t be the slightest doubt that the Grolier is genuine.”
This was the smoking gun.
If someone had tried to fake the Grolier Codex in the 1960s, they would have needed knowledge of Maya astronomy that wasn’t even available yet.
In other words, forging the text would have been impossible.
Why This Discovery Matters
The confirmation of the Grolier Codex as an authentic Maya manuscript is more than just an academic victory—it’s a window into the intellectual world of the ancient Maya.
It reveals their deep knowledge of astronomy, particularly their tracking of Venus cycles, which played a crucial role in their rituals and calendars.
It challenges assumptions about what we thought we knew about Maya literacy and manuscript culture.
It proves that Mesoamerican civilizations were producing written records earlier than previously believed.
For decades, scholars hesitated to fully embrace the Grolier Codex, fearful that they’d been duped. Now, those doubts can finally be put to rest.
A Genuine Piece of History
“A reasoned weighing of evidence leaves only one possible conclusion,” the researchers write.
Four intact Maya codices survive from the pre-Columbian period.
One of them is the Grolier Codex.
The manuscript, once dismissed as a fraud, is now officially the oldest surviving book in the Americas.
And that is a discovery worth rewriting history for.
What’s Next for the Grolier Codex?
With the codex now confirmed as authentic, researchers are eager to study it more closely.
What other secrets could it reveal about Maya civilization? Could there be other undiscovered manuscripts out there?
This revelation opens new possibilities in the field of Mesoamerican studies.
For now, the Grolier Codex stands as a testament to the resilience of ancient knowledge—surviving not just centuries of history, but also decades of doubt.
