The History and Origins of Druidism
Druids were skilled in the magical arts and it is possible that almost the entire system of Celtic occult belief had a Druidic origin. In this book, however, Lewis Spence deals exclusively with those occult practices which are definitely stated to have issued from a Druidic source. The practices he describes in graphic detail include Illusion and Transformation, forms of Divination, Prophecy and Astrology.
