The lines of Nazca are large figures drawn on the ground, often stylized animals of several kilometers long, visible in the desert of Nazca in southern Peru. The ground, on which these geoglyphs are outlined, is covered with pebbles colored red by iron oxide. By removing the pebbles, the Nazcas brought out a gypseous greyish soil, thus etching out the outlines of the figures they were tracing. Discovered in 1927, these geoglyphs are the creation of the Nazca civilization, a pre-Inca culture that existed between 300 BC - 800 AD. They were mostly made between 200 BC and 600 AD.
