It is hard to overestimate the importance of the contribution made by Dame Frances Yates to the serious study of esotericism and the occult sciences. To her work can be attributed the contemporary understanding of the occult origins of much of Western scientific thinking, indeed of Western civilization itself. The Occult Philosophy of the Elizabethan Age was her last book, and in it she condensed many aspects of her wide learning to present a clear, penetrating, and, above all, accessible survey of the occult movements of the Renaissance, highlighting the work of John Dee, Giordano Bruno, and other key esoteric figures. The book is invaluable in illuminating the relationship between occultism and Renaissance thought, which in turn had a profound impact on the rise of science in the seventeenth century. Stunningly written and highly engaging, Yates' masterpiece is a must-read for anyone interested in the occult tradition.

The Fourth Book of Occult Philosophy, by Henry Cornelius Agrippa and unnamed others, is considered one of the cornerstones of Western magic, and the grimoires it contains are among the most important that exist in the Western tradition. For more than three hundred years, this mysterious tome has been regarded as difficult or even impossible to understand--until now. Occult scholar Donald Tyson presents a fully annotated, corrected, and modernized edition of Stephen Skinner's 1978 facsimile edition of the original work, which was six tracts published as one volume in 1655. For the first time, these classic works of Western magic have been rendered fully accessible to the novice practitioner, as well as occult scholars and skilled magicians. Tyson presents clear instruction and practical insight on a variety of magic techniques, providing contemporary magicians with a working grimoire of the arcane.

" It is expedient therefore, to make four unequal lines, by the points casually set down; and to joyne together those points; and out of the points which are not joyned together, which do remain in the heads of the lines, (as it is done in Geomancie) extract one figure; and the signe of the Zodiack that answereth to that figure, put for the Ascendent, for the words sake. If Acquisition arise from the heads of those four Lines, let Aries be placed in the Ascendent; if Laetitia, or the lesser Fortune put Taurus in the Ascendent; if Puer or Rubeus, place Gemini; If Albus, Cancer; if Via, Leo; if Conjunction or the Dragons Head, Virgo; if Puella, Libra; if Amissioor Tristitia, Scorpio;ifthe Dragons Tail, Sagittary;if Populus, Capricorn; if Fortuna major, Aquary; if Carcer, then put Pisces for the Ascendent. Aerwards in the second House, let that signe be placed which immediately succeeds the other....."

Investigating the impact of Arabic medieval astrological and magical theories on early modern occult philosophy, this book argues that they provided a naturalistic explanation of astral influences and magical efficacy based on Aristotelian notions of causality.

This is the first modern study of Agrippa's occult philosophy, revealing it to be a coherent part of his intellectual work. It analyzes the text of "De occulta philosophia," explicating the sophisticated structure and argument of the work.
