I found these links at The Wild Hunts Links Roundup. I especially liked the ones to a Review of Ron Hutton’s Pagan Britain book, The dark deep roots of Britain’s fascination with Witchcraft, and at the latter i found Forget the Da Vinci Code – this is the real mystery of the Knights Templar. The latter has a video embedded below and looks like it may have 9 parts. There are lots of other great links at TWH also.
Postscript – I watched or rather listened to all nine of these videos, which are also at their websitesite and found them to be into Many interesting parts of Goddess worship history and probably what the original Templars were all about. Enjoy
