Nazca Lines – AI Revolutionises Archaeological Discoveries

The Nazca Lines, located in southern Peru, are a collection of ancient geoglyphs that have puzzled archaeologists for decades. Discovered in the mid-1920s, these massive designs have been attributed to a pre-Incan civilisation. Recent advancements in artificial intelligence (AI) have led to a remarkable surge in the discovery of new geoglyphs. In less than six months, researchers identified 303 new figures using drones and AI technology. This breakthrough marks the potential of AI to transform archaeological research and enhance our understanding of ancient cultures.

About Geoglyphs

Geoglyphs are large motifs created on the ground by manipulating natural materials. The Nazca Lines are particularly notable for their size and complexity. They were formed by removing stones and soil to create negative images that stand out against the desert landscape. The arid climate of the Nazca Pampa has helped preserve these designs for over 2,000 years.

Historical Context

The first systematic study of the Nazca Lines began in 1926, led by Peruvian archaeologist Toribio Mejia Xesspe. As aviation technology developed in the 1930s, pilots began to uncover more geoglyphs. However, identifying these patterns from the ground remains challenge due to their vast scale and the limitations of traditional survey methods.

AI and Drone Technology

A recent study published in the *Proceedings of the National Academy of Sciences* utilised drones to survey over 600 square kilometres of the Nazca Pampa. Researchers employed an AI application developed in collaboration with IBM to analyse aerial images. This technology filtered out 98% of the imagery, allowing archaeologists to focus on 2% of the data, leading to the identification of 1,309 potential sites.

The Significance of New Discoveries

The newly identified geoglyphs provide invaluable vital information about the culture that created them. Previous theories about their purpose ranged from astronomical significance to alien involvement. Current archaeological perspectives suggest these geoglyphs served as sacred spaces for community rituals and communication about agricultural practices.

Implications for Archaeology

The dramatic increase in the rate of geoglyph discoveries signals a potential revolution in archaeology. Historically, discoveries occurred at a rate of 1.5 per year from the 1940s to the 2000s. This figure rose to 18.7 per year from 2004 to 2020. The recent findings indicate a 16-fold acceleration in discoveries, demonstrating how AI can enhance archaeological methodologies and uncover previously hidden aspects of ancient civilisations.

Future Research Directions

The study suggests that many more geoglyphs remain undiscovered, with estimates of at least 500 additional figures yet to be identified. Continued integration of AI and drone technology in archaeological research will likely yield further vital information about the Nazca Lines and other historical sites.
