For over a century, the Nazca Lines in Peru have puzzled archaeologists. These massive geoglyphs, created by the Nazca people between 200 BC and 650 AD, cover vast areas of desert, depicting animals, plants, and tools. Many of these intricate designs, only visible from the sky, have long eluded full understanding.

Now, a collaboration between archaeologists and artificial intelligence (AI) has uncovered 303 new geoglyphs in just six months, doubling the known total. This breakthrough, made possible by AI, has provided fresh insights into the purpose of the lines, which were long debated. As reported by Science Focus, this discovery marks a significant leap forward in solving one of archaeology’s greatest puzzles.

The Power of AI in Archaeology

Researchers, including Prof. Masato Sakai from Yamagata University’s Institute of Nazca in Peru, have partnered with IBM scientists to teach AI how to analyze massive swathes of aerial imagery, identifying previously hidden geoglyphs. This collaboration has significantly accelerated the process, making it possible to conduct surveys in a fraction of the time it would normally take. As Sakai explains, “The ability to conduct the [survey] in such a short period was thanks to the use of AI.”

AI is not only helping to identify more geoglyphs but also changing how archaeologists approach the study of ancient civilizations. By processing aerial imagery, AI can spot patterns that might have otherwise gone unnoticed by the human eye, offering a more efficient and precise way to map and understand historical remains.

The success of AI in the Nazca Desert is only the beginning, as the technology is already being applied to other archaeological sites across the world, from burial mounds to shipwrecks.

New Insights into the Nazca Lines’ Purpose

One of the most intriguing aspects of this AI-driven discovery is the potential to better understand the purpose of the Nazca Lines. Sakai’s team suggests that many of the new geoglyphs were part of ritual walkways, where individuals would walk along the lines to engage with the landscape and commune with the gods. AI’s ability to identify these new sites has helped confirm that the geoglyphs were designed not only as artistic expressions but also as spiritual and cultural symbols.

The AI system’s ability to process large datasets and identify geoglyphs that may have previously gone unnoticed opens up new possibilities for understanding the Nazca civilization’s connection to their environment, as well as their advanced knowledge of spatial design and astronomy.

As AI technology improves, it is expected to become even more accurate, allowing archaeologists to explore more areas with fewer resources. The ability to automate the detection of sites could drastically increase the speed and scope of archaeological research, uncovering hidden treasures and unlocking the secrets of ancient civilizations.
