Archaeologists have identified the name of a Maya mathematician-astronomer for the first time, revealing “White-Chested Fox” as the author of a complex formula inscribed on a 8th-century wall in Guatemala. The discovery, published in *Antiquity*, offers insight into the intellectual sophistication of the Classic Maya period.
The name Sak Tahn Waax, or “White-Chested Fox,” was uncovered in a chamber at Xultun, Guatemala, where researchers analyzed a set of hieroglyphs that include a mathematical formula. The text, dated to the mid-8th century, was found in Structure 10K-2, a masonry building near the ancient city of Tikal, which had been excavated since 2010. The formula, described as “super nerdy math” by researcher Heather Hurst, links astronomical cycles such as Venus and Mars to Maya calendar systems, demonstrating a deep understanding of timekeeping.
The Name Revealed
The identification of Sak Tahn Waax marks a breakthrough in Maya studies. The name appears in the final hieroglyph of Text 19, a set of 11 inscriptions that include the phrase “so says,” indicating attribution. Guatemalan Culture Minister Luis Mendez, citing the Ministry of Culture, called it “the only work of its kind attributed to a mathematician from the Maya Classic period.”
The discovery was made possible by epigraphic analysis of over 50 mathematical and astronomical microtexts on the chamber’s walls. Franco Rossi, who led the multispectral imaging of Text 19, described the moment of revelation: You can look at some of these texts forever, and it won’t click. Then, one day you see it, and it just clicks. The formula’s unique arrangement of calendrical intervals, including 2,920 days—equivalent to eight solar years or five Venus cycles—shows the Maya’s ability to reconcile celestial and terrestrial time.
Deciphering the Formula
The formula’s complexity lies in its use of “abbreviated shorthand,” where partial dates are implied rather than fully written. “They give you the first half of a notation and the second half is implied,” Hurst noted. The text includes references to the Maya’s Tzolkin (260-day sacred calendar), Tun (360-day year), and Uinal (20-day month), alongside Mars cycles. David Stuart, who co-authored the *Antiquity* study, compared the discovery to “finding the whiteboard of an ancient scientist’s office.”
The chamber’s context further underscores its significance. Painted with human figures and hieroglyphic texts, it was likely a workspace for scribes. Researchers believe it was used during the Classic period, before the Maya collapse. The presence of the name Sak Tahn Waax suggests that intellectual achievement was as valued as artistic or political work. “The discovery shows people that the Maya were very clever, creative, intellectually curious people who taught and learnt and sometimes did math for the sake of it,” said Eric Heller of the University of Southern California Dornsife.
A Legacy of Scientific Inquiry
The find challenges the notion that Maya science was purely practical. “They were doing this abbreviated shorthand, so they give you the first half of a notation and the second half is implied,” Hurst said. The formula’s focus on idealized numbers rather than immediate applications suggests a culture that valued knowledge for its own sake. This is the first named scientist from the pre-Columbian Americas, Stuart emphasized.
Gerardo Aldana of UC Santa Barbara noted that the attribution of the formula to a specific individual “suggests that mathematicians were recognized in Maya society as much as artists were.” This aligns with the chamber’s depiction of “obsidians”—rulers and elites—with Yax We’n Chan K’inich, an 8th-century Xultun ruler, seated in a niche on the north wall. The blend of art, science, and governance in the space reflects the Maya’s holistic approach to knowledge.
The discovery also underscores the role of technology in modern archaeology. Digital enhancements of scanned inscriptions, combined with multispectral imaging, allowed researchers to decode the text. “It’s just super nerdy math,” Hurst said. The work, published in *Antiquity*, is a testament to the Maya’s enduring legacy as pioneers of astronomical and mathematical thought.
