Ancient mathematical texts discovered at the Maya city of Xultun in Guatemala have revealed the name of a Maya astronomer for the first time, offering rare evidence of the scholars behind one of the ancient world’s most advanced systems of mathematics and astronomy. Researchers reconstructed and transcribed dozens of tiny inscriptions found on the plaster walls of a small building at the site. Their work uncovered a unique mathematical formula and identified its author, marking the first known case of a Classic Maya mathematician-astronomer being directly credited for his work. The findings were published in the journal Antiquity. Wall writings...
