This month's Fortean Times has a special feature on this English writer who has since the 60s covered many topics in his books such as numerology, UFOs, megaliths, Glastonbury...and much more. Basically before Michell Glastonbury was another Somerset town - actually that's a bit of an exaggeration but you get my drift. I learnt quite a few things about this great writer I didn't know - he was once a friend of the Rolling Stones for example - and named the UFO club for Pink Floyd. So if you have a liking for this original thinker maybe you should try and get hold of Fortean Times before it sells out.
In a way reading John Michell makes you into a bit of a dreamer - a 'normal person' would scoff at some of his ideas but even a rationalist reductionist would find it hard to argue with some of the strength of his notions and how convincing they are. My favourite book is 'Twelve Tribe Nations' which argues a literal 'enchantment' when perpetual choirs chanted and the world was divided along astrological lines. I can't really explain it in a few lines - you have to read the book and consider the evidence before judging it a fancy. Michell is no fake or fakir - he's a true English visionary and eccentric with a great writing style. I recommend you give him a read. Whether he's writing about Crop Circles, Glastonbury, strange phenomena or whatever it's hard to put him down - his ideas intoxicate the mind. Wiki
