Nazca Lines

These pictures show what are known as "Nazca Lines". They were created by the Nazca tribe that flourished in Peru between 200 B.C. and 600 A.D. Most archeologists suggest they had a religious or ritual purpose. The lines are etched into stone and some span over 1000 feet. Tourist often view the drawings from an airplane. Without such technology, the Nazca may have perfected the drawings using surveying techniques to create a grid as a guide.

Notice that they tail of this monkey includes a spiral, a common motiff throughout Earth Art.
