The Society of the Horseman’s Word, otherwise known as the Horse Whisperers.
This fraternity recited passages from the Bible backwards and practiced folk
magic as part of their rituals, in addition to having Masonic-style oaths.
They were a satanic group linked to spy activities, banking, and ritual sacrifices.
Sound familiar.
And of course, the group has been glorified with lies by the Redford film of the same name.
