“P.D. Newman’s new book Theurgy: Theory and Practice, is one of the best and most important books I have read in a long time. He does for theurgy what Jake Stratton-Kent did for goetia, taking it back to its archaic roots, showing the development, providing excellent scholarship, and workable material. This is a great book.”

– David Rankine, author of The Grimoire Encyclopaedia

“P. D. Newman’s Theurgy: Theory and Practice is a wonderfully informed book on practical theurgy, with special emphasis on its relation to what is generally referred to as ‘shamanism.’ The text is well-referenced, making it useful for scholars, as well as very readable, making it of value to the lay reader and practitioner. Theurgy is a wonderful addition to anyone’s library, as there is ample material here for literally everyone.”

– MARK STAVISH, author of Egregores

“Theurgy is commonly thought of as a spiritual practice that began with Julian the Chaldæan in the second century CE and blended Eastern practices with rational Greek thought, primarily Neoplatonism. However, Neoplatonists such as Porphyry and Proclus pointed to theurgic elements in the archaic Homeric epics. While Eastern influences are not disputed, the author convincingly argues that they are a mere sprinkling and that the roots of theurgy are predominantly Greek, having begun at the time of Homer and practiced continuously thereafter. Readers thirsty for more knowledge about the path of theurgy will not be disappointed.”

– TONY MIERZWICKI, author of Hellenismos

“P. D. Newman tells a compelling story of the origins and development of theurgy, a fundamental spiritual practice in ancient Mediterranean religion. His argument is supported by the best contemporary scholarship on theurgy and on classical religion and philosophy. Newman has also assembled and organized a wealth of source material (in translation), which would otherwise be difficult to collect. Read this book for a fascinating exploration of theurgy over more than a millennium, from Homer to Proclus.”

“A must for those interested in ancient Greek thought about souls and soul flight. According to Newman, theurgy can be traced as early as Porphyry’s and Proclus’s para-Homeric sources that describe iatromanteia, which translates to ‘healer-seer’ who took soul flights. Tying these types of experiences to early shamanic themes reflected in works such as the Odyssey, the author weaves a compelling narrative of the early history and practical importance of theurgy. Newman’s analyses are thought-provoking and demand attention as he outlines a good case for how souls and the shamanic craft have shifted in antiquity from the early writings of authors such as Parmenides and Empedocles to the later Neoplatonists. The ideas contained in this book are sure to form a new starting point for many future analyses on how shamanic themes developed among the Greeks.”

“P. D. Newman’s impressive book on theurgy and Homer covers the interpretation of myth and ritual theurgy by the Neoplatonists. With references to the Pre-Socratics, Pythagoras, Plato, and even Egyptian and Mesopotamian texts, Newman correctly understands theurgy to be distinguished from other forms of magic as initiatory and anagogic. He presents detailed and critical accounts of ancient astrological and cosmological phenomena and follows the best scholarship in developing his rather original conclusion: that Proclus and company were indeed justified in seeing in Homer the esoteric meanings they teased out of his texts. The work reveals a new angle and a new dimension of the still emerging landscape of late antique thought. It will be of interest to scholars in the field and to the general reader interested in philosophical, religious and mystical ideas.”
