A Treatise on Angel Magic is an important contribution to students of the occult, many of whom have been clamouring for this new edition. What sets it apart from other books in the field is that it does not represent merely one viewpoint on Western esoterica and the study of angel magic but, rather, encompasses all the important thinking on these topics from medieval times and the Renaissance. Rich with charts and explanatory diagrams, A Treatise on Angel Magic is a seminal source work in hermetics.
