Supernatural by Graham Hancock
Originating with Hancock undertaking Ayahuasca ceremonies in the Amazon, he charts the history of cave art, fairies, witchcraft, alien abduction and establishes the clear evidence of all these phenomena linking throughout history and culture to present us with definate icons of the supernatural realms experienced through altered states of consciousness...all of which science is only just touching upon!
A thoroughly enjoyable, fact-packed and thought provoking nutshell of one of the possible origins for religion and art.

The book is Graham Hancock's Supernatural, Meetings with the Ancient Teachers of Mankind. The first thing to note about it is that it's 710 pages long with a further 45 pages of appendixes and 91 pages of footnoting. Don't let that put you off, however, there's a lot in it for people of our ilk. (Elk just wasn't funny)
This is more a summary than a review. I'll try to be succinct but it will be lengthy nonetheless. I'll post it in instalments. Be patient, it may initially look like the summary of someone's 'trip' but it does go somewhere.
