What distinguished the true alchemist from the fraud? This question animated the lives and labors of the common men—and occasionally women—who made a living as alchemists in the sixteenth- and seventeenth-century Holy Roman Empire. As purveyors of practical techniques, inventions, and cures, these entrepreneurs were prized by princely patrons, who relied upon alchemists to bolster their political fortunes. At the same time, satirists, artists, and other commentators used the figure of the alchemist as a symbol for Europe’s social and economic ills. Drawing on criminal trial records, contracts, laboratory inventories, satires, and vernacular alchemical treatises, Alchemy and Authority in the Holy Roman Empire situates the everyday alchemists, largely invisible to modern scholars until now, at the center of the development of early modern science and commerce. Reconstructing the workaday world of entrepreneurial alchemists, Tara Nummedal shows how allegations of fraud shaped their practices and prospects. These debates not only reveal enormously diverse understandings of what the “real” alchemy was and who could practice it; they also connect a set of little-known practitioners to the largest questions about commerce, trust, and intellectual authority in early modern Europe.

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.

In The Business of Alchemy, Pamela Smith explores the relationships among alchemy, the court, and commerce in order to illuminate the cultural history of the Holy Roman Empire in the sixteenth and seventeenth centuries. In showing how an overriding concern with religious salvation was transformed into a concentration on material increase and economic policies, Smith depicts the rise of modern science and early capitalism. In pursuing this narrative, she focuses on that ideal prey of the cultural historian, an intellectual of the second rank whose career and ideas typify those of a generation. Smith follows the career of Johann Joachim Becher (1635-1682) from university to court, his projects from New World colonies to an old-world Pansophic Panopticon, and his ideas from alchemy to economics. Teasing out the many meanings of alchemy for Becher and his contemporaries, she argues that it provided Becher with not only a direct key to power over nature but also a language by which he could convince his princely patrons that their power too must rest on liquid wealth. Agrarian society regarded merchants with suspicion as the nonproductive exploiters of others' labor; however, territorial princes turned to commerce for revenue as the cost of maintaining the state increased. Placing Becher’s career in its social and intellectual context, Smith shows how he attempted to help his patrons assimilate commercial values into noble court culture and to understand the production of surplus capital as natural and legitimate. With emphasis on the practices of natural philosophy and extensive use of archival materials, Smith brings alive the moment of cultural transformation in which science and the modern state emerged.

William Newman and Lawrence Principe reveal the hitherto hidden laboratory experiments of a famous alchemist and argue that many of the principles and practices characteristic of modern chemistry derive from alchemy.

George Starkey—chymistry tutor to Robert Boyle, author of immensely popular alchemical treatises, and probably early America's most important scientist—reveals in these pages the daily laboratory experimentation of a seventeenth-century alchemist. The editors present in this volume transcriptions of Starkey's texts, their translations, and valuable commentary for the modern reader. Dispelling the myth that alchemy was an irrational enterprise, this remarkable collection of laboratory notebooks and correspondence reveals the otherwise hidden methodologies of one of the seventeenth century's most influential alchemists.

What did it mean to believe in alchemy in early modern England? In this book, Bruce Janacek considers alchemical beliefs in the context of the writings of Thomas Tymme, Robert Fludd, Francis Bacon, Sir Kenelm Digby, and Elias Ashmole. Rather than examine alchemy from a scientific or medical perspective, Janacek presents it as integrated into the broader political, philosophical, and religious upheavals of the first half of the seventeenth century, arguing that the interest of these elite figures in alchemy was part of an understanding that supported their national—and in some cases royalist—loyalty and theological orthodoxy. Janacek investigates how and why individuals who supported or were actually placed at the traditional center of power in England’s church and state believed in the relevance of alchemy at a time when their society, their government, their careers, and, in some cases, their very lives were at stake.

Both the quest for natural knowledge and the aspiration to alchemical wisdom played crucial roles in the Scientific Revolution, as William R. Newman demonstrates in this fascinating book about George Starkey (1628-1665), America's first famous scientist. Beginning with Starkey's unusual education in colonial New England, Newman traces out his many interconnected careers—natural philosopher, alchemist, chemist, medical practitioner, economic projector, and creator of the fabulous adept, "Eirenaeus Philalethes." Newman reveals the profound impact Starkey had on the work of Isaac Newton, Robert Boyle, Samuel Hartlib, and other key thinkers in the realm of early modern science.
