The Nazca Lines
The geoglyphs of Nazca or “Nazca Lines” are a series of geometric shapes, miles of lines, and large drawings of animal figures (some as large as a football field) constructed on the desert floor in the Nazca region.
Many theories have arisen about the great geoglyphs. A large number of people over an extended period of time could have constructed the lines. Researchers have demonstrated techniques to see how this was done.By extending a rope between two posts and removing the red pebbles on the desert surface along the rope, the lines could be constructed. The contrast of the red desert pebbles and the lighter earth beneath would make the lines visible from a high altitude. Due to the simplistic construction of the geoglyphs, regular amounts of rainfall would have easily eroded the drawings but the dry desert environment has preserved the lines for hundreds of years.
The purpose of the lines continues to be debated. Some researchers theorize they were created for the gods to look upon them from above, while others suggest they were some sort of calendar with astronomical alignments that would aid in planting and harvesting of crops. Others have thought the lines were the pathways for important ceremonial processions.
