This book argues that we can only understand transformations of nature studies in the Scientific Revolution if we take seriously the interaction between practitioners (those who know by doing) and scholars (those who know by thinking). These are not in opposition, however. Theory and practice are end points on a continuum, with some participants interested only in the practical, others only in the theoretical, and most in the murky intellectual and material world in between. It is this borderland where influence, appropriation, and collaboration have the potential to lead to new methods, new subjects of enquiry, and new social structures of natural philosophy and science. The case for connection between theory and practice can be most persuasively drawn in the area of mathematics, which is the focus of this book. Practical mathematics was a growing field in early modern Europe and these essays are organised into three parts which contribute to the debate about the role of mathematical practice in the Scientific Revolution. First, they demonstrate the variability of the identity of practical mathematicians, and of the practices involved in their activities in early modern Europe. Second, readers are invited to consider what practical mathematics looked like and that although practical mathematical knowledge was transmitted and circulated in a wide variety of ways, participants were able to recognize them all as practical mathematics. Third, the authors show how differences and nuances in practical mathematics typically depended on the different contexts in which it was practiced: social, cultural, political, and economic particularities matter. Historians of science, especially those interested in the Scientific Revolution period and the history of mathematics will find this book and its ground-breaking approach of particular interest.

A breakthrough in occult studies that combines modern sigil techniques with traditional Enochian Magick and appeals to all levels of ritual magick practitioners, explorers of consciousness, scholars, dowsers, and tantric yoga practitioners Author and magick practitioner Robert Podgurski shares his discovery and development of the Grid Sigil--a tool for exploring the mysteries of embodiment and unity that bridges Enochian Magick with Sparean sigilization. Properly constructed, it emanates the root energies of the four elements bound by spirit in the space/time continuum. This text offers readers a variety of techniques for using the Grid Sigil and is an essential guidebook for understanding the connection between Enochian Magick, geomagnetism, shamanism, and other facets of Eastern and Western esotericism. Close attention is paid to critical metaphysical thought through in-depth analysis based in science, metaphysics, philosophical speculation, and illustrations.


Motion and Genetic Definitions in the Sixteenth-Century Euclidean Tradition

A significant number of works have set forth, over the past decades, the emphasis laid by seventeenth-century mathematicians and philosophers on motion and kinematic notions in geometry. These works demonstrated the crucial role attributed in this context to genetic definitions, which state the mode of generation of geometrical objects instead of their essential properties. While the growing importance of genetic definitions in sixteenth-century commentaries on Euclid’s Elements has been underlined, the place, uses and status of motion in this geometrical tradition has however never been thoroughly and comprehensively studied. This book therefore undertakes to fill a gap in the history of early modern geometry and philosophy of mathematics by investigating the different treatments of motion and genetic definitions by seven major sixteenth-century commentators on Euclid’s Elements, from Oronce Fine (1494–1555) to Christoph Clavius (1538–1612), including Jacques Peletier (1517–1582), John Dee (1527–1608/1609) and Henry Billingsley (d. 1606), among others. By investigating the ontological and epistemological conceptions underlying the introduction and uses of kinematic notions in their interpretation of Euclidean geometry, this study displays the richness of the conceptual framework, philosophical and mathematical, inherent to the sixteenth-century Euclidean tradition and shows how it contributed to a more generalised acceptance and promotion of kinematic approaches to geometry in the early modern period.

In The Building in the Text, Roy Eriksen shows that Renaissance writers conceived of their texts in accordance with architectural principles. His approach opens the way to wide-ranging discussions of the structure and meaning of a variety of literary texts and also provides new insights into the famed architectural ekphrases of Alberti and Vasari. Analyzing such words as &"plot,&" &"topos,&" &"fabrica,&" and &"stanza,&" Eriksen discloses the fundamental spatial symmetries and complexities in the writings of Ariosto, Shakespeare, and Milton, among other major figures. Ultimately, his book uncovers and clarifies a tradition of literary architecture that is rooted in antiquity and based on correspondences regarded as ordering principles of the cosmos. Eriksen&’s book will be of interest to art historians, historians of literature, and those concerned with the classical heritage, rhetoric, music, and architecture.

A central text of occult literature, now in a deluxe Weiser Ankh hardcover edition with new ancillary material (a new introduction, corrections to the text, appendices, and other enhancements) by renowned scholar Joseph Peterson. Three-piece quarter binding with black cloth spine and blue cloth over heavy boards Gold and black foil stamping on case with blind frame, front and back; gold stamping on spine Headbands, ribbon marker, and marbled endpapers. Printed on quality, archival (acid-free), 55# natural-colored paper, with sewn signatures and reinforced spine “This book is not just a fancier version of the older edition. Anyone interested in Renaissance magic or Enochian magic will want this on their shelf.” —Jason Miller, author of Consorting with Spirits and other books and courses Mysteriorum Libri Quinque—the Five Books of Mysteries—written by John Dee in the 16th century, remains to this day one of the most important core texts of occult literature and a comprehensive guide to Enochian magic, encompassing language, symbolism, rituals, and practical techniques. This deluxe Weiser Ankh edition is a compilation of John Dee’s secret spiritual treatises and was prepared from the original manuscript (preserved in the British Library) in Dee’s own handwriting. These secret writings were discovered long after John Dee’s death (c. 1609); they had been tucked away in a hidden compartment of an old wooden chest and were remarkably spared from destruction—uncovered only a few years before the Great Fire of London in 1666. In these five secret treatises, John Dee, one of the most renowned scholars of the Elizabethan era, records in minute detail his research into the occult. Throughout his life, Dee had kept concealed his writings on the nature of humankind’s contact with angelic realms and languages. In this comprehensive work, Joseph Peterson presents a brief biography of John Dee, detailing his work in astronomy, mathematics, navigation, the arts, astrology, and the occult sciences, and calling him a “true Renaissance man.” Although this present work is concerned primarily with Dee's occult experiments, through it, we catch many glimpses of Elizabethan life and politics. Mysteriorum Libri Quinque presents Dee’s main achievement: five books, revealed and transcribed between 1581 and 1583, detailing his system for communicating with the angels and bringing to light mysteries and truths that scholars and adepts have been struggling to understand and use ever since. While Dee’s influence was certainly felt in his lifetime, his popularity has grown tremendously since. His Enochian system was used and adapted by the Hermetic Order of the Golden Dawn and subsequently by Aleister Crowley. First published by Weiser Books in 2003 as John Dee’s Five Books of Mystery: Original Sourcebook of Enochian Magic, this new deluxe Weiser Ankh edition has been extensively updated and expanded. It includes new commentary that reflects twenty years of research by editor Joseph Peterson, corrections to the text based on a review of high-resolution scans of the original manuscripts only recently made available by the British Library, new appendices reflecting more recent scholarship, and translations of the many Latin passages and extensive footnotes, making this work more accessible to readers.

A step-by-step guide to the rituals of Enochian magic for reaching the higher spiritual realms • Reveals missing practical instructions for the Enochian magic system received by John Dee and Edward Kelley • Explains that the angelic realm is only the first and farthest away of the spiritual realms surrounding God • Shows how to connect with the higher worlds beyond the angels to tap more fully in to the magical power of the Divine In this comprehensive introduction to Enochian magic and beyond, John DeSalvo explains how the magic system transmitted by the angels to John Dee and Edward Kelley in the 16th century has until now remained incomplete and thus not as powerful as the angels intended. Drawing on his in-depth study of John Dee’s diaries, DeSalvo explains how Dee and Kelley were given the Enochian tables and calls but their communications with the angels were severed before they received the full practical instructions for Enochian magic. To this day, most magical groups improvise and make up rituals based on their own ideas and imagination--the magic they practice is not true angelic magic. After many successful Enochian magic rituals and years of his own spiritual work, DeSalvo has discovered additional key pieces to the magical system of Dee and Kelley, a system now known as Power Magic. He provides step-by-step instructions for more complete and accurate Enochian magic rituals and reveals how the angelic realm is only the first and farthest away of the spiritual realms surrounding God. He explains how to penetrate this angelic realm with Power Magic to reach higher spiritual worlds and receive more powerful knowledge and energy. He shows that by connecting with the higher worlds beyond the angels, we can tap more fully in to the magical power of the Divine and begin restoring the planetary magic of our most ancient ancestors.
