This encyclopedia is an up-to-date source of information on what are termed most usually earth mysteries or ancient mysteries - a term coined in the 1970s to describe a cross-disciplinary study of sacred landscapes, strange lifeways of former ages, ruined monuments and magical sites which reveal untold secrets of our spirituality, belief and knowledge. The book, which covers locations and sites world wide, brings together many strands of understanding and provides an insight into ancient knowledge. It is a balanced survey of an often over-sensationalized subject which seeks to dissolve numerous false mysteries.
