A well researched, thought provoking perspective from Graham Hancock who isn't afraid to push the boundaries and give us insight in to our past by connecting the dots of the history of ancient civilisations, time cycles that fit Plato's great year, Sun cycles and the fascinating mystery behind sites around the world built to align with Orion's belt. In conclusion it appears Graham is clearly on to something that Governments/authorities around the world are going out of thier way to hide... The series becomes more gripping with each episode, gradually piecing his theory together and it makes sense. The serpent spirit has many references, one analogy not used in this series is that of Kundalini rising through the chakras or the interpretation of the serpent of temptation in the garden of Eden, no doubt all these interpretations are connected which is fascinating. Therefore the stories of a great apocalypse is also an analogy of a transitional period of time in a cycle that's literally written in the stars.
