“The lines are found in a region of Peru just over 200 miles southeast of Lima, near the modern town of Nasca. In total, there are over 800 straight lines, 300 geometric figures and 70 animal and plant designs, also called biomorphs. Some of the straight lines run up to 30 miles, while the biomorphs range from 50 to 1200 feet in length (as large as the Empire State Building).”
What Are the Lines?
The lines are known as geoglyphs – drawings on the ground made by removing rocks and earth to create a “negative” image. The rocks which cover the desert have oxidized and weathered to a deep rust color, and when the top 12-15 inches of rock is removed, a light-colored, high contrasting sand is exposed. Because there’s so little rain, wind and erosion, the exposed designs have stayed largely intact for 500 to 2000 years.
Scientists believe that the majority of lines were made by the Nasca people, who flourished from around A.D. 1 to 700.
Certain areas of the pampa look like a well-used chalk board, with lines overlapping other lines, and designs cut through with straight lines of both ancient and more modern origin.
The Theories
The Kosok-Reiche astronomy theories held true until the 1970s when a group of American researchers arrived in Peru to study the glyphs. This new wave of research started to poke holes in the archeo-astronomy view of the lines (not to mention the radical theories in the ‘60s relating to aliens and ancient astronauts).
Johan Reinhard, a National Geographic Explorer-in-Residence, brought a multidisciplinary approach to the analysis of the lines: “Look at the large ecological system, what’s around Nasca, where were the Nasca people located.” In a region that receives only about 20 minutes of rain per year, water was clearly an important factor.
“It seems likely that most of the lines did not point at anything on the geographical or celestial horizon, but rather led to places where rituals were performed to obtain water and fertility of crops,” wrote Reinhard in his book The Nasca Lines: A New Perspective on their Origin and Meanings.
Anthony Aveni, a former National Geographic grantee, agrees, “Our discoveries clearly showed that the straight lines and trapezoids are related to water … but not used to find water, but rather used in connection with rituals.”
“The trapezoids are big wide spaces where people can come in and out,” says Aveni. “The rituals were likely involved with the ancient need to propitiate or pay a debt to the gods…probably to plead for water.”
Reinhard points out that spiral designs and themes have also been found at other ancient Peruvian sites. Animal symbolism is common throughout the Andes and are found in the biomorphs drawn upon the Nasca plain: spiders are believed to be a sign of rain, hummingbirds are associated with fertility, and monkeys are found in the Amazon—an area with an abundance of water.
“No single evaluation proves a theory about the lines, but the combination of archeology, ethnohistory, and anthropology builds a solid case,” says Reinhard. Add new technological research to the mix, and there’s no doubt that the world’s understanding of the Nasca lines will continue to evolve.
