Goetic divination has had a bad press from the urban literati of the Classical world up to the present day. In Goetic Divination, Jake Stratton-Kent provides an overview of the history of divination, as well as practical instruction on divinatory methods, including the use of astragals, pendulums and hydromancy. The pamphlet also includes an easily removable pendulum board.
