Especially so if they resemble a constellation, an animal, a shape and so on. Hieroglyphs that use indirect representations are more difficult to decipher, yet most of them have eventually been decoded. This is the hardest aspect to determine. A good example is the Great Pyramid of Giza. We have always known of its antiquity, and in the last century we have become aware of the mathematics contained within its dimensions.
Theories abound and can become overwhelming.
Therefore I have chosen to concentrate on a single, succinct idea, the cyclical global catastrophe , and apply it to not only the Giza complex, but every ancient site I study. The Nazca lines conform to these three rules. They are at least 1500 years old, and are capable of lasting very much longer than that. That they embody symbols is obvious, and it is my belief that they describe the Great Flood. The Nazca lines and figures cover a total area of 520 square kilometres.
