After five years of work and walking nearly 1,000 miles through the driest desert in the world, a British archaeologist believes he's solved one part of the mystery of Peru's Nazca Lines.
The ancient lines, known as "geoglyphs," crisscross Peru's Nazca desert, forming countless shapes that may date back to 500 B.C. In one particular region, researcher Clive Ruggles, of the University of Leicester's School of Archaeology and Ancient History, says he's identified a labyrinth.
Unlike many of the more famous animal-shaped Nazca Lines formations, Ruggles notes the labyrinth is barely discernible from the air. Indeed, writes Ruggles on his website, "it was not meant to be ‘seen’ from outside at all, but rather to be experienced from within. It was meant to be walked. This leads on to the question of by whom, and in what circumstances."

He speculates the labyrinth's construction occurred in the middle of he 800-year-long "Nazca period," around A.D. 500.
According to Discovery News, the labyrinth's path is predominantly shaped by 15 corners that alternately carry travelers toward and away from a large hill. The 2.7-mile long journey ultimately ends in a spiral passageway.
The structure has no clear purpose, leading to speculation in Science News that the path could have been reserved for spiritual journeys taken by shamans or Nazca gods.
Many of the Nazca lines are miles long and perfectly straight:
Ruggles and a colleague, Nicholas Saunders, of the University of Bristol's Department of Archaeology and Anthropology, report their findings in the December issue of Antiquities.
