Mysterious Nazca Line Geoglyphs Formed Ancient Pilgrimage Route

SAN FRANCISCO — The Nazca Lines, a series of fantastical geoglyphs etched into the desert in Peru, may have been used by two separate groups of people to make pilgrimage to an ancient temple, new research suggests.

But the purpose of the desert etchings may have changed over time.

The earliest Nazca Lines were created so pilgrims could view the markings along a ritual processional route, the researchers said. But later people may have smashed ceramic pots on the ground where the lines intersected as part of an ancient religious rite, according to a study presented here on April 16 at the 80th annual meeting of the Society for American Archeology.

The Nazca Lines were first brought to the world’s attention in the 1920s, when commercial airlines brought their passengers over the Nazca Pampa, an arid region of Peru locked between the Andes and the coast. Ancient people made the mysterious lines, shapes, otherworldly beings and animals between about 200 B.C. and A.D. 600 by removing the white rocks on the surface of the desert, revealing the reddish hued Earth underneath. Here, one of the iconic etchings, of “The Spider.”

What’s more, the Nazca Lines may have been created by at least two different groups of people who lived in different regions of the desert plateau, researchers said. [See Images of the Mysterious Nazca Lines]

Mysterious carvings

In one of the driest places on Earth, locked between the Andes Mountains and the coast, more than a thousand geoglyphs dot the landscape. People from an ancient civilization created the shapes between 200 B.C. and A.D. 600, by removing the reddish rocks on the surface of the desert, revealing the white-hued earth beneath.

The strange shapes in the desert include animals such as camelids, dogs and monkeys, as well as fanciful supernatural beings, scenes of decapitation and trophy heads, and geometric designs such as trapezoids, lines and triangles. Though the mysterious shapes gained widespread attention in the 1920s, when plane passengers saw them from above, people who lived there likely saw them even earlier while walking the hilltops in the Nazca plateau.

Researchers at Yamagata University have analyzed hundreds of the geoglyph. Based on their analysis, they have found multiple types of etchings. Many of those images are Some, such as “The Condor,” shown here, tend to use subject matter such as animals.

Archaeologists have long puzzled over the purpose of the Nazca Lines. Some researchers have argued the Nazca lines form a labyrinth. Others have said the lines and figures matched up with the constellations in the sky or with subterranean water routes. And still others have said the Nazca Lines were part of an ancient pilgrimage route.

Two cultures?

In recent years, researchers at Yamagata University in Japan have uncovered 100 geoglpyhs, as well as shards of broken ceramics at the intersection points of some of the lines.

To understand exactly how all of these images fit together, Masato Sakai of Yamagata University and his colleagues analyzed the location, style and method of construction for some of these newfound geoglpyhs. Sakai found that about four different styles of geoglyphs tended to be clustered together along different routes leading to a vast pre-Incan temple complex in Peru known as Cahuachi. Archaeological evidence, such as several temples and pyramids, as well as a trove of severed heads, suggests that Cahuachi was once a religious center where pilgrims brought offerings.  [12 Strangest Sights on Google Earth]

The researchers have also noticed differences in how certain etchings were constructed. For some, people removed rocks from the interior of the shape, while in others people removed rocks from the exterior to form the outline. Here, an image called “The Monkey,” which is grouped with many biomorphic images in a certain region of the Nazca Plain.

In addition to showing different content, the geoglyphs were also constructed differently from each other, made by removing rocks from the interior of the images in some cases and the border in others, Sakai said. For instance, images of animals such as condors and camelids were found along a route that started from the Ingenio River, which the team roughly categorized as type A and type B, respectively.

“The geoglyphs of type A and B are located not only in the area adjacent to the Ingenio Valley but along the pathway to Cahuachi. Therefore it seems reasonable to assume that type A and B geoglyphs were drawn by the group from the Ingenio Valley,” Sakai told Live Science.

Meanwhile, a separate style of images, such as the supernatural beings and thetrophy heads, were concentrated in the Nazca Valley and its route to Cahuachi, likely made by a distinct group of people who lived in that region. A third group of geoglyphs, likely made by both groups, was found in the Nazca Plateau between the two cultures.

This image, called “The Astronaut,” is considered a kind of supernatural being, and is one of the most well-known of the geolgyphs. It was rediscovered in the 1960s. The Astronaut is found along with several other geoglyphs of other supernatural beings, trophy heads and camelids animals, the researchers said.

Changing uses

The purpose of the geoglyphs may have also changed over time from what archaeologists call the final Formative period, which spanned until A.D. 200, to the early Nazca period, which ended in A.D. 450. The smashed ceramics dated to the later period.

“Our research revealed that the Formative geoglyphs were placed to be seen from the ritual pathways, while those of the early Nazca period were used as the loci of ritual activities such as intentional destructions of ceramic vessels,” Sakai said.

Here, another one of the iconic images in the Nazca Plain, called “The Dog.” Certain types of animal images tended to clump in one region, along a path leading to an ancient temple complex of Cahuachi. Researchers now hypothesize that two separate groups of people, one living in the INgeio Valley, and another living in the Nazca River Valley, both took pilgrimage routes along the geoglyphs.

And the ancient desert inhabitants continued making the lines beyond that time, Sakai said.

“Even after the collapse of the Cahuachi temple, trapezoids and straight lines continued to be made and used,” Sakai said.

Not all the lines show images of people or animals. Some of the geoglyphs are wavy lines, spirals intersecting lines and trapezoids. Researchers believe that at least some of the lines were meant to be walked as a labyrinth. Still others see it as a guide to the constellations, with one 1940s American scientist calling them the “largest astronomy book in the world.” Still others have argued that the images were meant to reveal the paths of subterranean water sources in the incredibly parched region, which gets an average of just 0.16 inches (4 mm) of rainfall a year.
