An A.I. Model Helped Uncover 303 Previously Unseen Nazca Lines in Peru
In 2022, we shared news of a monumental discovery at Peru’s Nazca Pampa, a UNESCO World Heritage site once home to pre-Inca Indigenous peoples who were fond of etching gargantuan artworks into the earth’s surface. Discovered in 1927, archaeologists spent nearly a century uncovering 430 figurative glyphs depicting animals, people, and hybrid creatures.
But thanks to a new A.I.-trained system, researchers have identified an additional 303 drawings in just six months as detailed in a study published this week in the Proceedings of the National Academy of Sciences. Included in the findings are various birds, cats, ceremonial acts, and even a killer whale wielding a weapon.
Dating back at least 2,000 years, the works offer insight into the cultural and spiritual practices of the ancient civilization. Although theories about the purpose of the lines range from calendars to agriculture and human migration, researchers know they were made by removing darker stones to reveal lighter, desert sand below.
Whereas drones have helped to identify the giant line drawings that stretch across the desert, the A.I. model has been adept at detecting the smaller, relief-type renderings that mainly portray wild animals and are more difficult to find.
