The Heptarchia Mystica (or the Mystic Sevenfold Dominion)
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.
