Derived from two previously unpublished seventeenth century manuscripts on angel magic, this coveted book contains the final corrected version of John Dee's great tables and an expansion of his most prized book of invocations.

Discover what happened to John Dee's most important manuscript, his book of personal angelic invocations, and how it was developed by seventeenth century magicians into a full working magical system. Learn how only a small part of this material reached the Hermetic Order of the Golden Dawn and was suppressed―never appearing in Israel Regardie's monumental work on the Order rituals.
