For the First Time, Archaeologists Have Identified a Named Mayan Astronomer
For decades, the ancient Maya have been celebrated as master astronomers and mathematicians — a civilization that tracked celestial cycles with breathtaking precision, built calendars that still fascinate modern scientists, and encoded complex knowledge into stone and pigment. Yet one thing has remained stubbornly out of reach: the identities of the individual minds behind those calculations. We know the temples. We know the cities. We do not, by and large, know the people who did the math.
That has now changed. Archaeologists working in Guatemala have, for the first time, deciphered the name of a specific Mayan astronomer and mathematician from symbols painted on a mural — a breakthrough announced Monday by Guatemala’s Ministry of Culture.
The name is Sak Tahn Waax, which translates to “White-chested Fox.” His work was found in drawings spanning a remarkably long period — from 400 BC to 900 AD — at the San Bartolo-Xultun archaeological site, located near Guatemala’s border with Mexico. And according to researchers, what he left behind is nothing less than a complete mathematical and astronomical formula.
What Was Found — and Where
The San Bartolo-Xultun site is no stranger to archaeological significance. It sits in the Petén region of northern Guatemala, a landscape of dense jungle that has concealed Mayan ruins for centuries. The site has previously yielded extraordinary murals and inscriptions, but this latest discovery adds an entirely new dimension: the identification of an individual author behind Mayan scientific work.
Luis Mendez, Guatemala’s culture minister, told reporters that researchers at Xultun unearthed what he described as a “complete mathematical and astronomical formula” authored by Sak Tahn Waax. Mendez emphasized that this is the only work of its kind attributed to a mathematician from the Maya Classic period — the era generally regarded as the peak of Mesoamerican civilization, spanning roughly 250 to 900 AD.
That distinction matters. The Maya Classic period produced some of the civilization’s most sophisticated achievements in art, architecture, writing, and science. To be able to put a name to a mathematician from this era is to move from the abstract — “the Maya knew astronomy” — to the concrete: a person, with a name, who did the work.
How the Decipherment Was Done
The breakthrough did not come from a single dramatic moment of discovery but from a painstaking process of epigraphic analysis — the study and interpretation of ancient inscriptions. According to the Ministry of Culture’s statement, the identification was “made possible by the epigraphic analysis of more than 50 mathematical and astronomical microtexts written on the wall.”
More than 50 microtexts. Let that sink in. These are not grand, sweeping inscriptions carved into the face of a pyramid. They are small-scale writings, tucked into murals, interwoven with imagery. For years, they sat in plain sight — or as close to plain sight as anything can be in a jungle-shrouded ruin — their meaning locked behind a combination of weathering, obscurity, and the sheer difficulty of reading a writing system that took generations of scholars to decode.
Researchers used a combination of drawings, photographs, and scans of the inscriptions. These were then digitally enhanced — a step that proved critical. The enhancement revealed 11 hieroglyphs that could finally be deciphered, including the name of Sak Tahn Waax himself.
The glyphs appeared, in Mendez’s words, in “a context where art was intertwined with science, mathematics, astronomy and everyday life.” That interweaving is itself a significant detail. It suggests that for the Maya, science was not cordoned off into a separate intellectual category. Astronomical calculation lived alongside artistic expression, and both were embedded in the fabric of daily existence. The wall was a workspace, a canvas, and a record all at once.
What the Calculations Reveal
Beyond the astronomer’s name, researchers identified a series of calculations and tables that employ astronomical and calendrical units of time. This is consistent with what scholars already know about Mayan science: the civilization maintained multiple interlocking calendars, tracked the movements of Venus and other celestial bodies with remarkable accuracy, and used sophisticated mathematical systems — including the concept of zero, which they developed independently.
The ministry did not release the full contents of the formula, and detailed academic analysis will likely take time. But the identification of calendrical and astronomical units within these microtexts suggests that Sak Tahn Waax was engaged in the kind of work that required both long observation and rigorous computation. He was, in modern terms, doing research — and now, for the first time, we can attach a name to it.
Why This Matters
There is a tendency, when discussing ancient civilizations, to speak of their achievements in the passive voice. “The pyramids were built.” “The calendar was developed.” “Astronomical observations were recorded.” This framing erases the individuals responsible. It treats civilizations as monolithic forces rather than collections of people — some brilliant, some ordinary, all contributing to a collective enterprise.
The identification of Sak Tahn Waax pushes back against that erasure. He is not a legend or a king commemorated in a grand monument. He is a mathematician, named in the margins of his own work, recognized not for conquest or lineage but for the calculations he left on a wall. That is a rare and valuable thing.
It also underscores how much remains to be found. The Maya civilization was vast, spanning parts of modern-day Mexico, Guatemala, Belize, Honduras, and El Salvador. Its cities were numerous, its written records extensive, and its jungle-shrouded ruins have yielded secrets slowly and often only with the help of modern technology.
A Civilization’s Long Decline
The Maya civilization began its decline around 900 AD, a period often referred to as the Classic Maya collapse. The causes remain debated — drought, warfare, overpopulation, and political fragmentation all likely played roles. But the civilization did not vanish overnight. Maya communities persisted, and their descendants continue to live in the region today.
The final blow to the political and architectural edifice of the civilization came with the arrival of Spanish conquistadors at the turn of the 16th century. Colonization brought disease, violence, and systematic destruction of Mayan texts and cultural artifacts — losses that make discoveries like the one at Xultun all the more precious. What survived is a fraction of what once existed.
Recent Discoveries in Context
The identification of Sak Tahn Waax comes amid a wave of recent Mayan archaeological discoveries, many of them enabled by technology that would have been unimaginable a generation ago.
Last year, Guatemala’s culture ministry announced that archaeologists had unearthed the remains of a Mayan city nearly 3,000 years old in northern Guatemala, complete with pyramids and monuments. The find added to the growing understanding that the Maya were building complex urban centers far earlier than once assumed.
In 2024, an American doctoral student discovered a sprawling Maya city hidden within dense jungle in Mexico. The scale of the find was striking, and it highlighted how much of the Maya world remains concealed beneath the canopy.
One of the most transformative tools in recent Mayan archaeology has been lidar — light detection and ranging — a technology that involves shooting lasers down from aircraft to penetrate dense vegetation. Lidar can reveal the outlines of buildings, roads, and entire cities beneath the jungle, mapping terrain that would take years to survey on foot. It has fundamentally reshaped the field, revealing that Mayan urban centers were larger and more interconnected than previously believed.
The Intersection of Technology and Ancient Knowledge
What is striking about the Sak Tahn Waax discovery is that it relied on a different kind of technological intervention — not lasers from the sky, but digital enhancement of images captured at ground level. The microtexts were always there, on the wall. What changed was the ability to see them clearly enough to read them.
This is a reminder that archaeological discovery is not always about finding new things. Sometimes it is about seeing old things in new ways. The hieroglyphs that yielded Sak Tahn Waax’s name were not buried under soil or hidden in an unexplored cave. They were visible, at least in some form, to anyone who stood in front of that wall. But reading them required the right tools, the right expertise, and, perhaps most importantly, the right question — not just “what does this say?” but “who wrote this?”
What Comes Next
The Ministry of Culture’s announcement is, in effect, a first word rather than a last one. The full academic analysis of the Xultun microtexts will take time. Scholars will need to examine the astronomical and calendrical calculations in detail, compare them with known Mayan systems, and determine how they fit into the broader corpus of Mayan scientific writing.
There is also the question of whether more names are waiting to be found. If Sak Tahn Waax’s name was encoded in microtexts at one site, it is reasonable to suspect that other sites may hold similar clues. The Maya wrote prolifically. Their scribes, astronomers, and mathematicians were literate professionals who signed their work in various ways. The fact that this is the first such identification does not mean it will be the last.
For now, though, we have a name. Sak Tahn Waax — White-chested Fox — an astronomer and mathematician of the Maya Classic period, whose calculations survived centuries of jungle growth, centuries of decline, and centuries of obscurity to be read, at last, by people who finally had the tools to understand them. It is a small thing, a name. But it is also a doorway — into the mind of an individual who, more than a thousand years ago, looked up at the sky and did the math.
