In the middle of the fourteenth century, the Franciscan friar John of Rupescissa sent a dramatic warning to his followers: the end times were coming; the apocalypse was near. Rupescissa's teachings were unique in his era. He claimed that knowledge of the natural world, and alchemy in particular, could act as a defense against the calamity of the last days. He treated alchemy as medicine (his work was the conceptual forerunner of pharmacology), and reflected emerging technologies and views that sought to combat famine, plague, religious persecution, and war. In order to understand scientific knowledge as it is today, Leah DeVun asks that we revisit the Black Death, the Hundred Years' War, and the Avignon Papacy through Rupescissa's eyes. The advances he pioneered, along with the exciting strides made by his contemporaries, shed critical light on future developments in medicine, pharmacology, and chemistry.

Decodes the message held by this enigmatic monument, revealing the alchemical secret of time and the fate of humanity.

In 1573, the alchemist Anna Zieglerin gave her patron, the Duke of Braunschweig-Wolfenbüttel, the recipe for an extraordinary substance she called the lion's blood. She claimed that this golden oil could stimulate the growth of plants, create gemstones, transform lead into the coveted philosophers' stone—and would serve a critical role in preparing for the Last Days. Boldly envisioning herself as a Protestant Virgin Mary, Anna proposed that the lion's blood, paired with her own body, could even generate life, repopulating and redeeming the corrupt world in its final moments. In Anna Zieglerin and the Lion's Blood, Tara Nummedal reconstructs the extraordinary career and historical afterlife of alchemist, courtier, and prophet Anna Zieglerin. She situates Anna's story within the wider frameworks of Reformation Germany's religious, political, and military battles; the rising influence of alchemy; the role of apocalyptic eschatology; and the position of women within these contexts. Together with her husband, the jester Heinrich Schombach, and their companion and fellow alchemist Philipp Sommering, Anna promised her patrons at the court of Wolfenbüttel spiritual salvation and material profit. But her compelling vision brought with it another, darker possibility: rather than granting her patrons wealth or redemption, Anna's alchemical gifts might instead lead to war, disgrace, and destruction. By 1575, three years after Anna's arrival at court, her enemies had succeeded in turning her from holy alchemist into poisoner and sorceress, culminating in Anna's arrest, torture, and public execution. In her own life, Anna was a master of self-fashioning; in the centuries since her death, her story has been continually refashioned, making her a fitting emblem for each new age. Interweaving the history of science, gender, religion, and politics, Nummedal recounts how one resourceful woman's alchemical schemes touched some of the most consequential matters in Reformation Germany.

Rossiter History of Women in Science Prize, History of Science Society Winner, 2022 Award for Excellence in the Study of Religion: Historical Studies, American Academy of Religion Honorable Mention, 2023 John Boswell Prize, The Committee on Lesbian, Gay, Bisexual & Transgender History (CLGBTH) Longlisted, 2022 Lambda Literary Award for LGBTQ Studies, Lambda Literary Awards The Shape of Sex is a pathbreaking history of nonbinary sex, focusing on ideas and individuals who allegedly combined or crossed sex or gender categories from 200–1400 C.E. Ranging widely across premodern European thought and culture, Leah DeVun reveals how and why efforts to define “the human” so often hinged on ideas about nonbinary sex. The Shape of Sex examines a host of thinkers—theologians, cartographers, natural philosophers, lawyers, poets, surgeons, and alchemists—who used ideas about nonbinary sex as conceptual tools to order their political, cultural, and natural worlds. DeVun reconstructs the cultural landscape navigated by individuals whose sex or gender did not fit the binary alongside debates about animality, sexuality, race, religion, and human nature. The Shape of Sex charts an embrace of nonbinary sex in early Christianity, its brutal erasure at the turn of the thirteenth century, and a new enthusiasm for nonbinary transformations at the dawn of the Renaissance. Along the way, DeVun explores beliefs that Adam and Jesus were nonbinary-sexed; images of “monstrous races” in encyclopedias, maps, and illuminated manuscripts; justifications for violence against purportedly nonbinary outsiders such as Jews and Muslims; and the surgical “correction” of bodies that seemed to flout binary divisions. In a moment when questions about sex, gender, and identity have become incredibly urgent, The Shape of Sex casts new light on a complex and often contradictory past. It shows how premodern thinkers created a system of sex and embodiment that both anticipates and challenges modern beliefs about what it means to be male, female—and human.

Newton’s heretical yet equation-incisive writings on theology, spirituality, alchemy, and prophecy, written in secret alongside his Principia Mathematica • Shows how Newton’s brilliance extended far beyond math and science into alchemy, spirituality, prophecy, and the search for lost continents such as Atlantis • Explains how he was seeking to rediscover the one true religion that existed prior to the Flood of Noah, when science and spirituality were one • Examines Newton’s alternate timeline of prehistory and his study of prophecy through the Book of Revelations, including his prediction of Apocalypse in the year 2060 Isaac Newton (1643-1727) is still regarded by the world as the greatest scientist who ever lived. He invented calculus, discovered the binomial theorem, explained the rainbow, built the first reflecting telescope, and explained the force of gravity. In his famous masterpiece, Principia Mathematica, he described the mechanics of the physical universe with unimagined precision, proving the cosmos was put together according to laws. The perfection of these laws implied a perfect legislator. To Newton, they were proof that God existed. At the same time Newton was writing Principia Mathematica, he was writing a twin volume that he might have called, had it been completed, Principia Theologia--Principles of Theology. This other masterpiece of Newton, kept secret because of the heresies it contained, consists of thousands of essays providing equation-incisive answers to the spiritual questions that have plagued mankind through the ages. Examining Newton’s secret writings, John Chambers shows how his brilliance extended into alchemy, spirituality, the search for lost continents such as Atlantis, and a quest to uncover the “corrupted texts” that were rife in the Bibles of his time. Although he was a devout Christian, Newton’s work on the Bible was focused not on restoring the original Jewish and Christian texts but on rediscovering the one true religion that existed prior to the Flood of Noah, when science and spirituality were one. The author shows that a single thread runs through Newton’s metaphysical explorations: He is attempting to chart the descent of man’s soul from perfection to the present day. The author also examines Newton’s alternate timeline of ancient history and his study of prophecy through the Book of Revelations, including his prediction of an Apocalypse in the year 2060 followed by a radically transformed world. He shows that Newton’s great hope was that these writings would provide a moral compass for humanity as it embarked upon the great enterprise that became our technological world.

The Age of the Discovery of the Americas was concurrent with the Age of Discovery in science. In The Alchemy of Conquest, Ralph Bauer explores the historical relationship between the two, focusing on the connections between religion and science in the Spanish, English, and French literatures about the Americas during the early modern period. As sailors, conquerors, travelers, and missionaries were exploring "new worlds," and claiming ownership of them, early modern men of science redefined what it means to "discover" something. Bauer explores the role that the verbal, conceptual, and visual language of alchemy played in the literature of the discovery of the Americas and in the rise of an early modern paradigm of discovery in both science and international law. The book traces the intellectual and spiritual legacies of late medieval alchemists such as Roger Bacon, Arnald of Villanova, and Ramon Llull in the early modern literature of the conquest of America in texts written by authors such as Christopher Columbus, Amerigo Vespucci, José de Acosta, Nicolás Monardes, Walter Raleigh, Thomas Harriot, Francis Bacon, and Alexander von Humboldt.
