Archaeologists have identified the name of a Maya mathematician-astronomer, Sak Tahn Waax, or “White-chested Fox,” through inscriptions at the Xultun site in Guatemala, marking the first known attribution of a specific piece of work in mathematics or astronomy from the Classic Maya period to a specific individual.
The discovery, published in *Antiquity*, centers on a chamber at Xultun where researchers uncovered over 50 mathematical and astronomical “microtexts.” One of these inscriptions, deciphered using a combination of drawing, photography, and digitally enhanced images, bears the name Sak Tahn Waax alongside a formula tracking celestial cycles, including the 260-day ritual day-count, the solar year, and planetary movements of Venus and Mars. “This fills out an important dimension of Classic Maya life that had typically been reconstructed through ethnohistories and Spanish accounts written centuries later,” said archaeologist Heather Hurst.
Unearthing a Lost Scholar
The Xultun site, located 25 miles northeast of Tikal, was originally reported in 1915 but has seen little archaeological excavation until more recent research began in 2008. Franco Rossi of MIT and his team began analyzing the site, including structure 10k-2. A breakthrough came when Rossi noticed a faint scrawl on the room’s east wall, which he later realized was a name. “You can look at some of these texts forever, and it won’t click,” Rossi said. “Then, one day you see it, and it just clicks.”
The name “Sak Tahn Waax” was linked to a formula that calculated a 2,920-day cycle—the convergence of 8 solar years and 5 Venus years. This “rough draft” of calculations, described as akin to “an early version of a well-known manuscript, or a sketch of a great artwork,” reveals the Maya’s understanding of timekeeping. “The math involves his unique understanding of connections and patterns between several cycles of time,” noted Mayanist David Stuart, from the University of Texas at Austin. The formula’s complexity suggests Sak Tahn Waax was a mathematician-astronomer.
The First Named Scientist of the Ancient Americas
Until this discovery, archaeologists had only identified names of Maya kings, queens, or other political figures. This is the first named scientist from the pre-Columbian Americas, said Stuart. The inscription on the chamber’s wall read “so says Saktahnwaax,” which suggests that either the person themselves or someone else “signed” the work, attributing the formulas to Saktahnwaax. This contrasts with the anonymity of other scholars behind computational timekeeping.
The findings also highlight the Maya’s scientific legacy. The Maya adopted scientific traditions independent from those of the “Old World,” Stuart explained. Still, the Maya were paying close attention to the same celestial phenomena as everyone else and meticulously “integrating their cycles into some unified vision of time,” he added. The Xultun inscriptions provide a link between these theoretical practices and the lived experiences of Classic Maya society, where dates corresponding to the movement of celestial bodies would have been used to schedule royal events and plan building projects.
What This Means for Maya Studies
The discovery opens new avenues for understanding Maya intellectual culture. Researchers are now analyzing other microtexts at Xultun, some of which may also be the work of the newly identified Sak Tahn Waax. “It’s similar to finding the whiteboard of an ancient scientist’s office and examining every scribble and note and formula on it,” said Stuart. The team’s methods—combining digital imaging, scale drawings, and traditional archaeology—aided in deciphering the messages. “Some are still obscure, and there are a few we still need to study,” Stuart added.
For historians, the name Sak Tahn Waax represents an individual achievement. It underscores the Maya’s role in a global network of ancient scientific inquiry. By attributing a specific mind to a formula, the discovery helps historians put the Maya civilization in context with other nations and empires of the time. As Rossi said, It’s one of these big sites that no one ever heard of.
The research has been published in *Antiquity*. The discovery underscores the importance of continued interdisciplinary research, as ancient knowledge often relies on fragments that can remain hidden until a collaborative effort uncovers its significance.
