''As a writer I thought that magical arts were language driven. I mean, we call them 'spells.' We have 'Words of Power, ' mantras, chants, and invocations. But with mathematics we have something else entirely. If I write down I saw three bluebonnets blooming today, you know exactly how many (even if you don't have the pleasure of knowing that it is the state flower of Texas). In fact, you can know the number even if you do not know English. In fact, you can know the number even if every single human perishes and you are some visiting alien from Tau Ceti. This would be true as your ability to grasp the Fundamental Theorem of the Calculus or the quadratic formula or )amusingly enough) Goedel's Incompleteness Theorems. Mathematics is where the mind can grasp the stuff of the Cosmos. We need only think of the terrible flash seen on Hiroshima on August 6, 1945, or the beauties of the Mandelbrot set, or watch children play at cutting a Moebius, to understand that math is at he secret heat of the physical world. And that math is the key to 'wonderworking'.'' -- Don We

Theurgy is commonly taken to denote a complex of rites which are based on the so-called Chaldean Oracles, a collection of oracles in hexameters, which were probably composed during the late 2nd century AD. These rituals are mostly known through Neoplatonic sources, who engage in a passionate debate about their relevance to the salvation of the soul and thus to the philosopher's ultimate goal. Ilinca Tanaseanu-Döbler examines the development of the discourse on theurgy, attempting to reconstruct what was understood as theurgic ritual in the late antique sources. Withstanding the temptation to impose a unity on the disparate sources which span several centuries, she thus goes beyond the picture of a coherent, extra-philosophical tradition drawn by the Neoplatonists to sketch the variations in the rituals subsumed under 'theurgy' and their function, and shows how every author constructs his own 'theurgy'. This perspective leads to consider theurgy as an example of an 'artificial' ritual tradition, composed from already existing elements to create something claimed as sui generis. Theurgy offers the great opportunity to look at such a tradition from its beginning up to its end and to analyse the mechanisms of inventing and reinventing such a ritual tradition in process.

Iamblichus was once considered one of the great philosophers. The Emperor Julian followed Iamblichus's teachings to guide the restoration of traditional pagan cults in his campaign against Christianity. Although Julian was unsuccessful, Iamblichus's ideas persisted well into the Middle Ages and beyond. His vision of a hierarchical cosmos united by divine ritual became the dominant worldview for the entire medieval world. Even Ralph Waldo Emerson wrote that he expected a reading of Iamblichus to cause a "revival in the churches." But modern scholars have dismissed him, seeing theurgy as ritual magic or "manipulation of the gods." Shaw, however, shows that theurgy was a subtle and intellectually sophisticated attempt to apply Platonic and Pythagorean teachings to the full expression of human existence in the material world.

"A collection of essays examining medieval and early modern texts aimed at performing magic or receiving illumination via the mediation of angels. Includes discussion of Jewish, Christian and Muslim texts"--Provided by publisher.

The ancient philosophy, in its original Orphico-Pythagorean and Platonic form, is not simply a way of life in accordance with the divine or human intellect (nous), but also the way of alchemical transformation and mystical illumination achieved through initiatic 'death' and subsequent restoration at the level of divine light. To use another mythical image, philosophy restores the soul's wings and leads the purified lover of wisdom to Heaven. As a means of spiritual reintegration and unification, ancient philosophy is inseparable from the hieratic rites. Therefore those scholars who themselves follow the anagogic path of Platonic tradition are more or less firmly convinced that their philosophy ultimately derives from the Egyptian and Mesopotamian temple liturgies and rituals, reinterpreted and revived by the Neoplatonists under the name of 'theurgy' in late antiquity. The theurgic 'animation' of statues appears to be among the main keys for understanding how various royal and priestly practices, related to the daily ritual service and encounter with the divine presence in the temples, developed into the Neoplatonic mysticism of late antiquity. The traditional theory of symbolism still stands on the Neoplatonic foundation established by Iamblichus, Proclus, and Damascius. "This book clearly establishes three things: that traditional myth (as the Neoplatonists maintained) is the symbolic expression of metaphysics, as metaphysics is the exegesis of myth; that Greek philosophy was not an isolated 'miracle' but a reinterpretation of perennial themes common to the ancient Near Eastern, Mesopotamian, Indian, and especially Egyptian religions; and that Platonic philosophical discourse was but one-half of a whole which included an invocatory/contemplative practice known as 'theurgy'. It was not merely the ancestor of western speculative philosophy, but an askesis, a yoga-a way of realization (though no longer a living tradition) worthy to be included among the great spiritual methods of all places and times." Charles Uupton, author of Knowings "In this most stimulating and wide-ranging work, Algis Uzdavinys, drawing on the resources of his enormous learning, leads Neoplatonic theurgy back to its roots in Ancient Egypt, thereby setting Platonic philosophy in a new and wider context. Students of Neoplatonism will find themselves much indebted to him for this, and all readers will find their outlook on life significantly changed.- Prof. John M. Dillon, Trinity College, Dublin, author of Middle Platonists

Why did ancient philosophers consult oracles, write about them, and consider them to be an important part of philosophical thought and practice? This book explores the extensive links between oracles and philosophy in Late Antiquity, particularly focusing on the roles of oracles and other forms of divination in third and fourth century CE Neoplatonism. Examining some of the most significant debates between pagan philosophers and Christian intellectuals on the nature of oracles as a central yet contested element of religious tradition, Addey focuses particularly on Porphyry's Philosophy from Oracles and Iamblichus' De Mysteriis - two works which deal extensively with oracles and other forms of divination. This book argues for the significance of divination within Neoplatonism and offers a substantial reassessment of oracles and philosophical works and their relationship to one another. With a broad interdisciplinary approach, encompassing Classics, Ancient Philosophy, Theology, Religious Studies and Ancient History, Addey draws on recent anthropological and religious studies research which has challenged and re-evaluated the relationship between rationality and ritual.

One of the foremost experts on magic, religion, and the occult in the ancient world provides an unparalleled exploration of magic in the Greco-Roman world, giving insight into the shifting ideas of religion and the divine in the ancient past and in the later Western tradition.

Attributed to Iamblichus (4th cent. AD), The Theology of Arithmetic is about the mystical, mathmatical and cosmological symbolism of the first ten numbers. Its is the longest work on number symbolism to survive from the ancient world, and Robin Waterfield's careful translation contains helpful footnotes, an extensive glossary, bibliography, and foreword by Keith Critchlow. Never before translated from ancient Greek, this important sourcework is indispensable for anyone intereted in Pythagorean though, Neoplatonism, or the symbolism of Numbers.

The Merging of the Individual with the Infinite.The literature on Theurgy is extensive, but much of it is theoretical and fairly inaccessible. Mouni Sadhu's Theurgy is different in that it is both thoughtful and lucid, and like his other works, including Samadhi and Meditation, remains unexcelled in the literature of practical philosophy for Western readers.The book is permeated with the burning faith and spiritual experience of the author and cannot fail to inspire the sensitive reader. Here the student is told in simple language the why, when and how to act. This differs from any other work on a similar theme and, to date, nothing like it has yet appeared.

Ritual, magic, liturgy, and theurgy were central features of Gnosticism, and yet Gnostic practices remain understudied. This anthology is meant to fill in this gap and address more fully what the ancient Gnostics were doing. While previously we have studied the Gnostics as intellectuals in pursuit of metaphysical knowledge, the essays in this book attempt to understand the Gnostics as ecstatics striving after religious experience, as prophets seeking revelation, as mystics questing after the ultimate God, as healers attempting to care for the sick and diseased. These essays demonstrate that the Gnostics were not necessarily trendy intellectuals seeking epistomological certainities. They were after religious experiences that relied on practices. The book is organized comparatively in a history-of-religions approach with sections devoted to Initiatory, Recurrent, Therapeutic, Ecstatic, and Philosophic Practices. This book celebrates the brilliant career of Birger A. Pearson.
