A Maya astronomer’s identity has been revealed for the first time, discovered in an inscription at the Xultun site in Guatemala, finally revealing a name behind their storied knowledge.
Despite the Maya’s renowned knowledge of math and astronomy, no individual had ever been directly associated with those accomplishments, unlike figures such as the Greek scholars Ptolemy or Archimedes.
Now, in a recent paper published in Antiquity, an international team of archaeologists has identified a name linked to the Maya’s sophisticated mathematical knowledge: Sak Tahn Waax.
From around 2000 BCE until the Spanish conquest in the 16th century, the Maya flourished across the Yucatán Peninsula, building a civilization renowned not only for its political and economic power, but also for its remarkable scientific and mathematical achievements. Although relatively few Maya texts survived the Spanish conquest, those that remain—along with archaeological evidence—show that the Maya precisely calculated the length of the solar year and carefully tracked the movements of the Moon and Venus across the sky.
The art, architecture, and glyphic texts of the Classic Maya likewise reflect a sophisticated understanding of the natural world, interwoven with Indigenous cosmological traditions.
That expertise shaped nearly every aspect of Maya society. Their intricate calendars guided agriculture, informed religious observances, and influenced political life. Yet despite the importance of this knowledge, the individuals responsible for developing it have largely remained anonymous.
Meaning “white-chested fox,” the name Sak Tahn Waax appears on a wall engraved with mathematical formulas, which archaeologists dated to the eighth century CE using inscribed dates and radiocarbon analysis. Researchers believe the room likely served as either a classroom or a workshop for producing books.
The inscription was first documented shortly after excavations began at Xultun in 2011. Although the team initially focused on other priorities at the site, deciphering the text remained an enduring objective.
Reading the inscription required years of laboratory work using color scans and multispectral imaging. After reconstructing the wall’s faded engravings, the researchers determined that the text contained instructions for synchronizing the planetary cycles of Mars and Venus with the Maya calendar, concluding with the signature, “so says Sak Tahn Waax.”
“It’s really elegant, complex math,” said co-author Heather Hurst, an archaeologist at Skidmore College. “That’s why he’s signing it.”
The strangest thing about the discovery may be how common signatures are in other elements of Maya life. Artists and scribes often signed ceramics, while important political and military figures’ names often adorn stelae and buildings. Despite this propensity to name individual Maya on things, those responsible for their legendary knowledge of math and science largely remain unknown.
The archaeologists behind this new study now suggest that those names may be available after all; it is only that researchers have not known where to look.
“There’s good evidence for codex book production,” said lead author Franco Rossi, an archaeologist at the Massachusetts Institute of Technology. “So if there’s going to be a name … this would be the most logical place.”
The researchers hope the discovery will inspire a deeper appreciation for Maya history and for the scholars whose work shaped the civilization.
“I would have loved to see Sak Tahn Waax and Ptolemy hanging out,” Hurst concluded. “They would have had a great discussion.”
The paper, “The Identification and Work of an Eighth-Century Maya Mathematician,” appeared in Antiquity on July 14, 2026.

Archaeologists have discovered an unusual artifact they say could represent the earliest known use of written numbers ever discovered in Mesoamerica.
The curious clay figurine features eleven small dots carved into its surface, appearing in three columns. Although its exact purpose remains unclear, researchers who report the discovery in Latin American Antiquity believe it could be one of the oldest examples of graphic notation that may have been used for rudimentary calculation or some similar purpose, dating to as far back as around 750 B.C.
Significantly, the researchers behind the recent study argue that this earliest known evidence of numerical writing could offer clues to “the relationship between numeration, bodies, and identity in ancient Mesoamerican worldviews.”
The figurine, roughly the size and shape of a small television remote, was unearthed at an ancient Mesoamerican site located along Guatemala’s Pacific coast, known as La Blanca. It is among a group of similar artifacts archaeologists call tab figurines, and hundreds of these mysterious relics are known from past discoveries at the site.
Named for their unusual slab-like appearance, these figurines also bear anthropomorphic qualities, which include depictions of jewelry and other ornamentation, although the tab figurines do not directly resemble human heads beyond the presence of such ornaments.
While similar past discoveries recognized as tab figurines have been made at La Blanca, the presence of dots appearing in columns makes this one very unique and presents a novel possibility: that the impressions on the statuette may not have been purely decorative.
“The ordered dots on the La Blanca tab figurine’s headdress, of course, raise more questions than they answer,” write authors Julia Guernsey, Stephanie M. Strauss, and Michael Love in their recent study. “This is often the case with unique examples such as this, which cannot be better contextualized within a larger grouping of like objects from La Blanca or elsewhere.”
“Although one might be inclined to dismiss the La Blanca figurine as a curiosity or an isolated addendum to the complicated history of first writing in Mesoamerica,” the authors go on to note, “we believe that it merits this thorough discussion.”
A clue to the artifact’s purpose may arise from the association between tab figurines and the human head, a region of the body that is traditionally associated with individual identity. This is significant, since archaeologists recognize a potential link between numbers and individual identity in the world of ancient Mesoamerica.
Based on existing archaeological knowledge from the region, it is known that experimentation with numbers had already begun around the time the artifact is believed to have been made. One well-characterized numerical system is known as the dot-and-bar system, which, as the name implies, relies on dots and bars to convey figures of one and five units, respectively.
“In the Mixtec and Aztec codices, one easily becomes accustomed to reading even long strings of single dots and quickly approximating their quantity, a visuo-summation process known as subitizing,” the authors write.
“And no matter what form Mesoamerican numerals took, the vigesimal system was rooted in metaphors/mnemonics of the body: specifically, 10 fingers and 10 toes and concepts of personhood anchored to the number 20,” they add.
Also of significance is the K’iche’ word for person, winik, which is the same word used for the number 20, and for a simple reason: it refers to the ten fingers and ten toes of the human body.
Although the connections between the unique figurine unearthed at La Blanca and existing knowledge of Mesoamerican number systems are compelling, the researchers caution against interpreting the artifact solely through the lens of later Mesoamerican writing systems. One main reason why is that scholars think there probably wasn’t ever any single method for recording numbers across the region.
Still, the artifact nonetheless joins a growing body of evidence that could point to the fact that the inhabitants of La Blanca were experimenting with symbolic communication, and at a time centuries before fully developed writing systems emerged in the region.
While the exact meaning of the dots on the statuette remains unknown, the researchers behind the study make a compelling case for why the markings may have represented a name, a date, or another personal identifier. If correct, the placement of the dots may hint at an early connection between numeration, identity, and social expression during a period when some of Mesoamerica’s first urban communities were taking shape.
“Yet a question remains as to whether the identity expressed by the La Blanca tab figurine with its 11 dots was human, supernatural, or a combination thereof,” the authors concede, although concluding that their assessment of the artifact strongly points to the known associations between time, numbers, and the concept of personhood as envisioned in the minds of ancient Mesoamericans.
“Early Mesoamerican conceptualizations of time and the nature of being, perhaps, were not so very different from those of Aristotle for whom Paul Ricoeur noted, ‘Being in time [meant] more than existing when time exists. It [meant] ‘being in number.’”
The study, “Numbers and Bodies: Potential Early Numeration on a Middle Preclassic Figurine from La Blanca, Guatemala,” was published in Latin American Antiquity.
