Something pretty exciting is happening in Mexico. Yes, the Popocatépetl is erupting again. All of that volcanic activity is ejecting new life into the old world of Aztec and Mayan civilization. As you may recall, archeologists recently discovered a thousand-year-old Mayan palace located 63 miles west Cancún in Yucatán, Mexico. Before that, the  National Institute of Anthropology and History (INAH) also found hundreds of archaeological artifacts nearby the Yucatán that, as experts put it, contain “invaluable information related to the formation and fall of the ancient City of Water Sorcerers, and who were the founders of this iconic site.” This year a new study confirmed that a gold bar found in 1981 in a Mexico City park was part of the Aztec treasure that was stolen by Hernan Cortes and the Spanish conquistadors 500 years ago. It feels like our ancestors are trying to tell us something. 

After decades of research, experts concluded in 2016 that a book they found years ago, in fact, is a 900-year-old authentic astronomy guide from the Mayan period. The book is called the Grolier Codex, and archaeologists say this is the oldest book found in the Americas.

One of the reasons the authenticity was always questioned is due to the backstory of how the book was found in the first place. According to ArsTechnica, the Grolier Codex was found by a Mexican collector named Josué Sáenz in 1966. Sáenz said that “a group of unknown men offered to sell the book to him, along with a few other items found “in a dry cave” near the foothills of the Sierra de Chiapas.” 

What made this book even more fascinating, yet troubling, was that Sáenz said the men told him if he took the book, he wouldn’t be able to show it to anyone. Others then told Sáenz that the book was a fake, but did allow archaeologist Michael Coe to show the book in New York. He later would give the book to the Mexican government.

The 10-page book is said to be an insightful guide into astronomy and how the Mayans kept track of the sun and the planets. It was their early forms of calendar-keeping.

ArsTechnica said the book was written during trying times — the late Mayan period. Brown University social scientist Stephen Houston described how each picture in the book offered critical information that Mayans needed for day-to-day duties. 

The images are of “workaday gods, deities who must be invoked for the simplest of life’s needs: sun, death, K’awiil—a lordly patron and personified lightning—even as they carry out the demands of the ‘star’ we call Venus. [The Dresden and Madrid Codices] both elucidate a wide range of Maya gods, but in Grolier, all is stripped down to fundamentals,” Houston said. 

What’s also fascinating about the timing of the book’s confirmation is that Michael Coe, the Yale anthropologist, who decoded the text, died last year at the age of 90.

The New York Times wrote in his obit that Coe was instrumental at deciphering Mayan code and giving the Mayans credit for their work when many wrote off the images as just that. 

In “Breaking the Maya Code” (1992), he theorized that anthropologists had never given the Maya adequate credit for their linguistic advances because of what he called ‘quasi-racism,’ or an ‘unwillingness to grant the brown-skinned Maya a culture as complex as that of Europe, China or the Near East.'”

As we previously noted, a more recent discovery was made just this week. A gold bar that was found in a park in Mexico City in 1981 was finally determined to be an authentic Aztec treasure.

It’s quite fascinating to see that just because artifacts are found, doesn’t necessarily mean they can be authenticated by archeologists with a snap of a finger. Their research takes years, sometimes decades. 

The National Institute of Anthropology and History said they used special equipment to research the gold bar including an X-ray Fluorescence (XRF) which is “a proven multi-elemental technique of high sensitivity, non-destructive, non-invasive and extremely fast.” 

With so many recent discoveries, we can only imagine what other types of treasures are still buried underneath the ancient lands of Mexico.
