Large ground features such as the Nazca Lines in Peru cause a lot of consternation to researchers of ancient cultures because they are enormous, sometimes abstract, images that can only be seen properly from the sky. My proposition continues to be that these creations are meant to be viewed by the sun and/or some other celestial entity of great importance to people with animistic religious belief systems. This being my position, one of the first things I do when examining what appears to be highly abstract ancient art imagery such as rock alignments, geoglyphs and intaglios* is look for how they interact with the sun. This video demonstrates how I do that and how sometimes just a little bit of astronomic research can produce possible answers to long held mysteries.
Rock alignment: an arrangement of rocks that create a linear formation leading to a location or aligning with the passing of a celestial object.
Geoglyph: an arrangement of rocks on the ground that creates abstract or representational shapes on the ground that span several meters or more in size.
Intaglio: abstract or representational shapes on the ground that are created by scraping the hard surface of the ground (often called “desert pavement”). These usually span several meters or more in size and are sometimes combined with geoglyph features and/or rock alignments.
