Archaeologists have transcribed mural symbols from Mayan ruins to learn the name of an astronomer and mathematician from the ancient civilization for the first time, Guatemala’s Ministry of Culture said Monday.

The signature of Sak Tahn Waax, or “White-Chested Fox,” was found inscribed in a 1,000-year-old chamber beneath present-day Guatemala

The name "White-chested Fox" was found in drawings dating from 400 BC to 900 AD at the San Bartolo-Xultun archaeological site.
