Peruvians walked their prayers into the earth - life - 26 January 2009 - New Scientist: "THE ancient, intricate geometric patterns stamped on the surface of a desert in Peru have long been thought of as messages to the gods, or as markers that tracked celestial objects. Now new details about these geoglyphs suggest they may have been made for 'prayer walking'.
The Nasca lines are a collection of lines, giant trapezoids, and figures of humans, plants and animals in a desert 400 kilometres south of Lima, Peru. They were created between 400 BC and AD 650 by the removal of reddish oxidised stones from the desert pavement to reveal the lighter sand beneath."
