In 2010, archaeologist David Stuart and his team discovered a painted chamber at the Maya site of Xultun in modern-day Guatemala. The chamber contained numerous mathematical and astronomical formulas, which appeared to be attributed to a specific individual. A paper published in Antiquity now identifies this individual as Saktahnwaax, meaning "White-Chested Fox," who likely lived around 800 CE. An inscription on the chamber's wall reads "so says Saktahnwaax," suggesting the formulas were signed by or attributed to this person. This marks the first time a Maya scientist has been named, as previous discoveries only identified kings, queens, or political figures.
