Complete Enochian Dictionary: A Dictionary of the Angelic Language as Revealed to Dr. John Dee and Edward Kelley.

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 Donald Laycock has thoroughly analysed the work of Dee and Kelley.
