An essential reference on Enochian language ("the language of the angels") as revealed to Dr. John Dee and Edward Kelley in the 16th century, with a new preface by Stephen Skinner. In 1581, Dr. John Dee, an advisor in the court of Queen Elizabeth I, began a series of experiments intended to explore the ability to contact the spirit world. With Edward Kelley acting as the medium in these experiments, Dee was able to record these communications as they were transmitted in Enochian, the language of the angels. Dr. Dee's efforts furthered the development of the Enochian system of magic, and his methods of invocation have been taken up and expounded upon by many magicians since. Donald C. Laycock has thoroughly analyzed the work of Dee and Kelley. In this volume, he recounts the history of their experiments. He provides a pronunciation guide for the twenty-one letters, significant to untangling both the meaning and the derivation of the messages handed down from Dee and Kelley, and an essential Enochian/English and English/Enochian dictionary. The result is a fascinating linguistic and magical mystery story, integral to any study of the Enochian tradition. This new edition of Laycock's work includes a new preface by Stephen Skinner that sets the tone and historical context for today's readers.
