is a complete system of planetary magic delivered to the

Elizabethan magus John Dee in 1582 through the crystal

scrying of Edward Kelley. It details the angels ruling the

planets and the days of the week, describes their functions

and how to invoke them. Neglected by the Hermetic Order of

the Golden Dawn and Aleister Crowley, the Heptarchia was

eventually published in 1983 after painstaking research by the

late Robert Turner, who collated the text from Dee's original

manuscripts. A second edition followed in 1986.

Unavailable for many years, the early editions are now

collectors' items. This new third edition has been carefully

revised and updated by Robin E. Cousins. The book is

dedicated to the memory of Robert Turner and his wife

Patricia Shore Turner and features a Foreword by Anne

Turner. Copiously annotated and illustrated throughout, the

work is complemented by a selection of essays by the authors

on related themes.
