Intervention by Alan Butler

Alan Butler has spent 30 years immersed in world history, writing books delving into neglected recesses of the past, including ancient cosmology. Three of his books written with co-author Christopher Knight have attained cult status: Civilization One (2004), Before the Pyramids (2009) and The Hiram Key Revisited (2010), all published by Watkins. His most recent title was City of the Goddess (also published by Watkins, 2011).
