Who is Lucifer? The orthodox Christian view tells us that he challenged God, fell from Heaven, tempted Eve and created death and suffering. Then he became Satan, horned king of Hell. Yet as Lynn Picknett explains, Devil was only a new incarnation of the old woodland deity Pan, while Lucifer was a personification of the Morning Star, the planet Venus and its goddess. 'He' was therefore originally 'she', and a divine representation of love, beauty and human warmth. Indeed, many ancient goddesses were known as Lucifera, or 'Light-bringer' - an honour extended to Mary Magdalene in her true role as goddess-worshipping priestess and Christ's successor. While thousands follow Lucifer in order to achieve earthly wealth and power; Picknett explains that such misguided behaviour is far from true Luciferan principles - the audacious pushing ever outwards of the limits of human knowledge, startlingly exemplified by the little-known heresies of Leonardo da Vinci. Ironically, controversial modern scientists, who see no proof of a God, much less of a Devil, may possess the key to the existence of the old archetypal adversaries. Urging a radical shift in both religious and scientific paradigms, Picknett draws together ancient heretical Christian and Egyptological texts, and the implications of abnormal psychology and the 'extreme possibilities' of certain barely-understood human attributes, to pose the extraordinary question: 'Have we humans actually created God and Lucifer, not merely as icons or metaphors, but in a terrifying way, literally?'
