The Nazca Lines

nasca1One thing that has always fascinated me are the Nazca Lines of Peru. Over 900 massive drawings spanning miles of the desert between the Nazca and Inca Valleys. Only fully visible and appreciated from the air, they are surrounded by mystery. Many people believe the lines were made to be seen by Alien visitors as landing sites. Others believe they were made as part of religious rites and now there is a theory that they were an elaborate map to finding water in the dry desert. Whatever their purpose they have lasted for centuries.

A Brief History of the Nazca People

The Nazca civilization flourished on the southern coast of Peru between 200 BCE and 600 CE. They settled in the Nazca and other surrounding valleys with their principal religious and urban sites being Cahuachi and Ventilla, respectively. The culture is noted for its distinctive pottery and textiles, and perhaps above all, for the geoglyphs made on the desert floor commonly known as Nazca lines. These can be simple lines, cleared spaces, or animals and figures traced in outline, and, as they cover several kilometres, they are best appreciated from the air.

The Nazca were contemporary with, and then outlasted, the Paracas culture and many Paracas sites have been nasca2discovered beneath Nazca settlements. Politically, the Nazca civilization has been described as a collection of chiefdoms occasionally acting in unison for mutual interest rather than as a single unified state. Or as M.E. Moseley puts it, “individuality – with cultural coherence, but without large-scale or integrated power – were Nazca hallmarks”. This interpretation is reinforced by the art and architecture of the Nazca which displays common themes across settlements but at the same time there is a general lack of uniform town planning or evidence of centralization. The maximum population of the Nazca has been estimated at 25,000 people, spread across small villages which were typically built on terraced hillsides near irrigated floodplains.

As they developed, the Nazca extended their influence into the Pisco Valley in the north and the Acari Valley in the south. In addition, as llamas, alpaca and vicuna do not survive in the coastal areas the use of their wool in Nazca textiles is evidence that trade was established with highland cultures. In addition, Nazca mummies have been discovered wearing headdresses made with the feathers of rainforest birds, once again, illustrating that goods were traded across great distances.

The Nazca Lines

In the Peruvian Desert, about 200 miles south of Lima, there lies a plain between the Inca and Nazca (sometimes also spelled Nasca) Valleys. Across this plain, in an area measuring 37 miles long and 1-mile wide, is an assortment of perfectly-straight lines, many running parallel, others intersecting, forming a grand geometric form. In and around the lines there are also trapezoidal zones, strange symbols, and pictures of birds and beasts all etched on a giant scale that can only be appreciated from the sky.

The figures come in two types: biomorphs and geoglyphs. The biomorphs are some 70 animal and plant figures that include a spider, hummingbird, monkey and a 1,000-foot-long pelican. The biomorphs are grouped together in one area on the plain. Some archaeologists believe they were constructed around 200 BC, about 500 years before the geoglyphs.

There are about 900 geoglyphs on the plain. Geoglyphs are geometric forms that include straight lines, triangles, spirals, circles and trapezoids. They are enormous in size. The longest straight line goes nine miles across the plain.

Discovery and Meaning

nacsa3Though discovered by Peruvian archaeologist Toribio Mejia Xesspe who spotted them while hiking through the surrounding foothills in 1927, the forms are so difficult to see from the ground that they were not widely known until the 1930’s when aircraft spotted them while surveying for water. The plain, crisscrossed, by these giant lines with many forming rectangles, has a striking resemblance to a modern airport. The Swiss writer, Erich Von Daniken, even suggested they had been built for the convenience of ancient visitors from space to land their ships. As tempting as it might be to subscribe to this theory, the desert floor at Nazca is soft earth and loose stone, not tarmac, and would not support the landing wheels of either an aircraft or a flying saucer.

So why are the lines there? The American explorer Paul Kosok, who made his first visit to Nazca in the 1940s, suggested that the lines were astronomically significant and that the plain acted as a giant observatory. He called them “the largest astronomy book in the world.” Gerald Hawkins, an American astronomer, tested this theory in 1968 by feeding the position of a sample of lines into a computer and having a program calculate how many lines coincided with an important astronomical event. Hawkins showed the number of lines that were astronomically significant were only about the same number that would be the result of pure chance. This makes it seem unlikely Nazca is an observatory.

Perhaps the best theory for the lines and symbols belongs to Tony Morrison, the English explorer. By researching the old folk ways of the people of the Andes mountains, Morrison discovered a tradition of wayside shrines linked by straight pathways. The faithful would move from shrine to shrine praying and meditating. Often the shrine was as simple as a small pile of stones. Morrison suggests that the lines at Nazca were similar in purpose and on a vast scale. The symbols may have also served as special enclosures for religious ceremonies.

Construction of the Lines

How were they built? The lines were apparently made by brushing away the reddish, iron oxide covered pebbles that compose the desert surface and uncovering the white colored sand underneath. In most places wind, rain and erosion would quickly remove all traces of this within a few years. At Nazca, though, the lines have been preserved because it is such a windless, dry and isolated location.

A writer by the name of Jim Woodman believes that the lines and figures could not have been made without somebody in the air to direct the operations.

“You simply can’t see anything from ground level,” states Woodman. “You can’t appreciate any of it from anywhere except from above. You can’t tell me the Nazca builders would have gone to the monumental efforts they did without ever being able to see it.”

Woodman has proposed that ancient hot-air balloons were used to get an aerial view of the construction. To prove his hypothesis, Woodman constructed a balloon using materials that would have been available to the Nazca people. He was able to conduct a successful flight, though it only lasted two minutes.

Most researchers are extremely skeptical of Woodman’s conclusions, however, as they find little evidence in the remains left by the Nazca of any balloon construction or operation.

It is more likely that the Nazca people used simple surveying techniques in their work. Straight lines can be made easily for great distances with simple tools. Two wooden stakes placed as a straight line would be used to guide the placement of a third stake along the line. One person would sight along the first two stakes and instruct a second person in the placement of the new stake. This could be repeated as many times as needed to make an almost perfectly-straight line miles in length. Evidence that the line makers used this technique exists in the form of the remains of a few stakes found at the ends of some of the lines.

The symbols were probably made by drawing the desired figure at some reasonable size, then using a grid system to divide it up. The symbol could then be redrawn at full scale by recreating the grid on the ground and working on each individual square one at a time.

Related to Water?

Recently two researchers, David Johnson and Steve Mabee, have advanced a theory that the geoglyphs may be related to water. The Nazca plain is one of the driest places on Earth, getting less than one inch of rain a year. Johnson, while looking for sources of water in the region, noticed that ancient aqueducts, called puquios, seemed to be connected with some of the lines. Johnson thinks that the shapes may be a giant map of the underground water sources traced on the land. Mabee is working to gather evidence that might confirm this theory.

Other scientists are more skeptical, but admit that in a region where finding water was vital to survival, there might well be some connection between the ceremonial purpose of the lines and water. Johan Reinhard, a cultural anthropologist with the National Geographic Society, found that villagers in Bolivia walk along a straight pathway to shrines while praying and dancing for rain. Something similar may have been done at the ancient Nazca lines.
