Belief in the One male God of Judaism, Christianity and Islãm can be traced back for something over 2,500 years to the time when the Hebrew scripture of Genesis was compiled in the 6th century BC. The narrative content of Genesis was clearly derived from older traditions but, on the face of it, we have no documentary evidence from any other source of a monotheistic culture in respect of this particular God from before that date. In The Origin of God, written but not published before his untimely death in August 2010, Laurence Gardner, author of the international bestsellers Bloodline of the Holy Grail, Genesis of the Grail Kings and Lost Secrets of the Sacred Ark, undertakes a biographical exploration of the deiform character variously known as Yahweh, Allãh, or simply The Lord. He seeks to uncover and evaluate His original identity, as against His eventual religiously motivated portrayals. Beginning with documents that pre-date the Bible, Laurence Gardner's final quest was to discover from all available sources what evidence there is, if any, to support the long-standing and widespread notion of God's existence, posing the question: If the Bible had never been written, would we know about God from any more original source?
