In a Collector's Edition entitled "Secrets of the Da Vinci Code," published by US News and World Report, there is a brief interview with James Robinson, general editor of the Nag Hammadi Library. In response to Dan Brown’s reference to the Nag Hammadi texts as scrolls, Robinson points out: “They are codices – books with individual pages. They are actually the oldest example we have of leather-bound books.” Amazingly, whatever the significance of their content (and we have just barely begun to comprehend what that might be), the Nag Hammadi Codices (NHC) are rare original artifacts, the earliest surviving examples of bound books.
A close reading of these arcane materials shows that Gnostics were deeply concerned with alien intrusion into human affairs. The entities they called Archons appear to be identical to the ET’s of modern Ufology. Both Grey and Reptilian types are explicitly described in the codices. I would estimate that up to one-fifth of the core material in the NHC concerns the Archons, their origin, methods and motives. 'The Sophia Mythos,' the Gnostic creation story, explains that the Archons arise due to an anomaly in the cosmic order. “The world system we inhabit came about by a mistake.” (The Gospel of Philip)
