Snakes and Gates: The Nodal Zodiacal Layer Of The 28 Shapes is a lectured delivered in 2021 at the AstroMagia Symposium by Elodie St Onge-Aubut and Chris Reppucci.  We discuss our ongoing research on what is commonly referred to as the Lunar Mansions and insights we have come to surrounding the Greek Magical Papyri, the Goetia, Taoistic holistic principles, world snakes, ancient practices, eclipse customs, the identity of Satan and the Oracular Astrological Tradition.
