Sixteen years later, someone was still staring at one faint patch of paint on its east wall, trying to work out what it said. The building is a small masonry structure at Xultun, a Maya site in the jungle of northeastern Guatemala, 340 kilometers southwest of Guatemala City. Its interior walls are covered with portraits of seated and kneeling men, each labeled with the title taaj — "obsidian," a term for a class of scribes and scholars — and with more than fifty faint mathematical notations scattered across the plaster like a scratch pad nobody bothered to erase.

It sits beside a formula unlike anything else recovered from the Maya world, one weaving the 260-day ritual count and the 365-day solar year together with the long, wandering cycles of Venus and Mars. Scholars have found Maya artists who signed their work before. They had never found t...
