You Won't Believe What AI Found Among the Nazca Lines in Peru’s UNESCO World Heritage Site

Unveiling the Mysteries of the Nazca Lines

The Nazca Lines, an enigmatic array of massive incisions etched into the arid desert landscape of Peru, have captivated scientists and tourists alike for nearly a century.

These geoglyphs, which depict an array of animals, plants, and geometric shapes, are best appreciated from the air, lying approximately 220 miles (350 kilometers) south of Lima.

As one of Peru's most prominent tourist attractions, the lines have sparked intrigue about their origins and purpose since their initial discovery in 1927.

Revolutionising Archaeological Discovery with AI

In a recent announcement in Lima, archaeologist Masato Sakai from Yamagata University highlighted a significant leap in archaeological research due to the incorporation of artificial intelligence.

Sakai explained:

“The use of AI in research has allowed us to map the distribution of geoglyphs in a faster and more precise way.”

This advancement came from a collaborative effort between Yamagata University’s Nazca Institute and IBM’s research division.

In collaboration with IBM's Artificial Intelligence team, researchers found a humanoid figure within the soil.

Traditionally, the painstaking process of visually identifying geoglyphs from high-resolution images was slow and prone to errors, risking the loss of vital information about these historical artifacts.

The study, published in the prestigious Proceedings of the National Academy of Sciences (PNAS), reveals how AI can accelerate archaeological discoveries, even in well-trodden areas like Nazca.

Over a six-month field survey, researchers employed AI-assisted image analysis of aerial photographs, resulting in the identification of 303 new geoglyphs.

On September 24, 2024, Yamagata University released an undated image showcasing nine of the 303 new geoglyphs discovered by its research team in Peru’s Nazca Pampas. The Nazca Lines, which are over 2,000 years old and recognised as a UNESCO World Heritage Site, feature geometric and animal figures that are visible only from the air.

The findings have immense implications for our understanding of the Nazca civilization, which thrived in southwestern Peru from 200 BC to 700 AD.

A New Era of Exploration: Discovering 303 New Geoglyphs

The magnitude of this discovery cannot be overstated.

The initial century of research yielded only 430 figurative Nazca geoglyphs.

However, the AI model excelled at detecting smaller relief-type geoglyphs, which are often elusive to the naked eye.

This breakthrough not only enhances our inventory of the Nazca Lines but also prompts deeper questions about the purpose behind their creation.

Among the newly identified figures are expansive linear geoglyphs that primarily represent wild animals, as well as smaller motifs featuring abstract humanoid forms and domesticated camelids, members of the camel family.

Sakai articulated the importance of these findings, saying,

“The traditional method of study was slow and carried the risk of overlooking some of them.”

This newfound efficiency means researchers can now explore vast regions of the Nazca Pampas, enhancing their understanding of the artistic and cultural significance of these remarkable lines.

The Enigma of the Nazca Civilization

The motivations behind the creation of the Nazca Lines remain shrouded in mystery.

Scholars have proposed various theories, with some suggesting that these geoglyphs may possess astrological or religious significance.

This speculation only adds to the allure of the lines, which, designated as a UNESCO World Heritage site, stand as a testament to the ingenuity and creativity of the Nazca civilization.

As researchers continue to unravel the secrets of the Nazca Lines, the application of AI not only marks a significant milestone in archaeological exploration but also revitalises interest in these ancient wonders.

The fusion of technology and archaeology is paving the way for a deeper understanding of our past, making the ancient geoglyphs more accessible and comprehensible than ever before.
