The Nazca Lines: A Mystery on the Plains


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

 Though 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.

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.

it is nice, in this post creativity is amazing. You are creating many stuff in this blog. Your weblog shared more information about Nazca lines. This is interesting mystery. A new Towing truck service near me available. This is best company. I repaired my car from this company. It is provide best service and offer.
