“This is one of the most important books on medieval magic to be published in many years. Enormously popular for decades, Ars Notoria was adapted and mutated into many versions, making it very challenging to understand. It is exciting to see an expert translation based on Véronèse’s reliable critical edition of the Latin versions and other primary texts. Matthias Castle’s tome is massive but worth every penny for its encyclopedic but lucid treatment of the many elements, such as the angelology, magical figures, rituals, art of memory, and liberal arts. Given the significant impact Ars Notoria had on later magical texts, including the Key of Solomon and Sworn Book of Honorius, Castle’s edition should be valuable to scholars and practitioners alike.” * Joseph H. Peterson, author, translator, and creator of the Esoteric Archives website * “One of the lost treasures of medieval occultism, the Ars Notoria is a system of Solomonic angelic magic used by students and scholars to attain knowledge of the arts and sciences. Matthias Castle has done an exemplary job in translating the original texts and setting out all the details of the notory art for today’s scholars and practitioners of magic.” * John Michael Greer, coauthor and cotranslator of The Complete Picatrix: The Occult Classic of Astrol * “This volume offers readers for the first time an English translation of this important work of image magic, based on the best available critical edition. Readers can count on a combination of readability and accuracy, and the book represents a substantial contribution by rendering this text accessible to a new audience of students and practitioners alike.” * David Porreca, Ph.D., associate professor and codirector of the medieval studies undergraduate progr * “Offers a methodical foundation for understanding and exploring the various manuscripts of the Ars Notoria tradition and its historical contexts. Richly illustrated with a wide evidentiary range of the Ars Notoria’s sacred diagrams, figures, sigils, and seals from across the manuscript corpus and presenting section-by-section close readings of the prayerful and conjurational texts in question, this book furnishes those enamored of the notory art a deeper understanding of its peculiar prayers and protocols. This work should provide all those interested in medieval angelology, manuscript illumination, grimoiric conjuration, and visual cultures of sacred art a valuable historical resource for understanding and engaging with these most pious and pedagogical of grimoiric traditions.” * Alexander Cummins, Ph.D., historian and coauthor of An Excellent Booke of the Arte of Magicke *
