The treatise of the great philosopher and mystic, Jacob Boehme’s Of the Three Principles of Divine Being, 1619, is a key to his complete work, its historical context, and its role in German intellectual history.

Most professional historians see the relationship between pre-modern and modern alchemy as one of discontinuity and contrast. Mike A. Zuber challenges this dominant understanding and explores aspects of alchemy that have been neglected by recent work in the history of science. The predominant focus on the scientific aspect of alchemy, such as laboratory experiment, practical techniques, and material ingredients, argues Zuber, marginalizes the things that render alchemy so fascinating: its rich and vivid imagery, reliance on the medium of manuscript, and complicated relationship with religion. Spiritual Alchemy traces the early-modern antecedents of modern alchemy through generations of followers of Jacob Boehme, the cobbler and theosopher of Görlitz. As Boehme's disciples down the generations -- including the Silesian nobleman Abraham von Franckenberg and the London-based German immigrant Dionysius Andreas Freher, among others -- studied his writings, they drew on his spiritual alchemy, adapted it, and communicated it to their contemporaries. Spiritual alchemy combines traditional elements of alchemical literature with Christian mysticism. Defying the boundaries between science and religion, this combination was transmitted from Görlitz ultimately to England. In 1850, it inspired a young woman, later known as Mary Anne Atwood, to write her Suggestive Inquiry into the Hermetic Mystery, usually seen as the first modern interpretation of alchemy. Drawing extensively on manuscript or otherwise obscure sources, Zuber documents continuity between pre-modern and modern forms of alchemy while exploring this hybrid phenomenon.

Jacob Boehme’s Aurora (Morgen Röte im auffgang, 1612) exercised a vast open or underground influence on popular and mystical religion, poetry, and philosophy from Germany to England to Russia. This beautiful and highly original work containing elements of alchemical, esoteric, and anticlerical thought is a portal to the cultural, scientific, and theological currents on the eve of the Thirty Years' War. Its author heralded the new heliocentrism, opposed intolerance and religious conflict, and entertained an ecstatic vision of order reconciled with freedom. This first modern English translation places the translated text opposite an edition of the German manuscript from the author’s own hand. Also included is the brief, influential Fundamental Report (Gründlicher Bericht, 1620) in a critical edition and translation. An extensive commentary that cites documents of the time offers access to the sources of Boehme’s themes and concepts.

Jacob Boehme, the seventeenth-century German speculative mystic, influenced the philosophers Hegel and Schelling and both English and German Romantics alike with his visionary thought. Gnostic Apocalypse focuses on the way Boehme's thought repeats and surpasses post-reformation Lutheran thinking, deploys and subverts the commitments of medieval mysticism, realizes the speculative thrust of Renaissance alchemy, is open to esoteric discourses such as the Kabbalah, and articulates a dynamic metaphysics. This book critically assesses the striking claim made in the nineteenth century that Boehme's visionary discourse represents within the confines of specifically Protestant thought nothing less than the return of ancient Gnosis. Although the grounds adduced on behalf of the "Gnostic return" claim in the nineteenth century are dismissed as questionable, O'Regan shows that the fundamental intuition is correct. Boehme's visionary discourse does represent a return of Gnosticism in the modern period, and in this lies its fundamental claim to our contemporary philosophical, theological, and literary attention.

The volume offers a survey of the contribution of German literature and culture to the evolution of ecological thought. As the field of ecocritical theory and practice is rapidly expanding towards transnational and global dimensions, it seems nevertheless necessary to consider the distinct manifestations of ecological thought in various cultures. In this sense, the volume demonstrates in twenty-six essays from different disciplines how German literature, philosophy, art, and science have contributed in unique ways to the emergence of ecological thought on national and transnational scale. The volume maps the most important and characteristic of these developments both on a theoretical and on a textual-analytical level. It is structured in five parts ranging from proto-ecological thought since early modern times (part I) to major theoretical approaches (part II), environmental history (part III), and ecocritical case studies (part IV), to ecological visions in different media and art forms (part V). The four editors have widely published and are actively involved in ecocritical literary and cultural studies. The group of editors consists of two scholars of German literature and cultural studies, Gabriele Duerbeck and Urte Stobbe (both University of Vechta), a scholar in German and comparative literature, Evi Zemanek (University of Freiburg), as well as a scholar of Anglo-American ecoliterature and ecocriticism, Hubert Zapf. All of them are involved in various projects and research networks on ecology and literature. The contributors of the individual chapters likewise are all experts in their respective fields, ranging from German literature, history, environmental studies, art history, music and art. The book is a unique and readily accessible collection of essays that is of relevance not only for a German and continental European but for a worldwide audience.

Today we are used to clear divisions between science and the arts. But early modern thinkers had no such distinctions, with ‘knowledge’ being a truly interdisciplinary pursuit. Each chapter of this collection presents a case study from a different area of knowledge.
