In the desert of southern Peru, a mystery has been unfolding over decades.
Hundreds of years ago, the people who lived nearby carved the ground with giant lines to create pictures and symbols that can only be fully appreciated from the sky. These are the Nazca glyphs, mysterious designs whose purpose has baffled archaeologists ever since.
Since their first discovery in the 1940s, around 430 glyphs have been discovered on the arid plateau known as the Nazca Pampa.
Now, using drones and AI, a team led by archaeologist and anthropologist Masato Sakai of Yamagata University in Japan has discovered a jaw-dropping 303 more in just six months – nearly doubling the known number.
With the discovery comes new insight regarding the function of the mysterious symbols.

AI-accelerated Nazca survey nearly doubles the number of known figurative geoglyphs and sheds light on their purpose
The improved account of figurative geoglyphs enables us to analyze their motifs and distribution across the Nazca Pampa. We find that relief-type geoglyphs depict mainly human motifs or motifs of things modified by humans, such as domesticated animals and decapitated heads (81.6%). They are typically located within viewing distance (on average 43 m) of ancient trails that crisscross the Nazca Pampa and were most likely built and viewed at the individual or small-group level. On the other hand, the giant line-type figurative geoglyphs mainly depict wild animals (64%). They are found an average of 34 m from the elaborate linear/trapezoidal network of geoglyphs, which suggests that they were probably built and used on a community level for ritual activities.
I suppose modern technology isn’t all bad.
