The study evaluates Paracelsus’s and Paracelsian-Weigelian microcosmogonies, i.e. theories concerning the nature and creation of human beings, especially their biblical underpinnings, and particularly in the light of Luther’s and Lutheran anthropological and biblical-exegetical stances. The Lutheran approach to the origin and components of human beings—as seen in Luther’s early Magnificat Commentary and the Genesis Commentary of his late career—relied on such magisterial principles as adherence to sola scriptura, literal biblical exegesis, and the hermeneutical standard to ‘let scripture interpret scripture,’ whereas (...) the Paracelsians, Weigelians, and Pseudo-Weigelians—in such works as Paracelus’s Astronomia Magna (1537/38) and the anonymous Astrologia Theologizata (1617)—employed such extra-biblical concepts as ‘sidereal bodies,’ the ‘light of nature,’ and a microcosm-macrocosm theory based on an alchemical interpretation of the limus terrae of Genesis 2:7. Seventeenth-century Orthodox Lutherans, including Nikolaus Hunnius and Ehregott Daniel Colberg, castigated the ‘heretical’ in Paracelsus and the Astrologia Theologizata. The study also addresses the authorship of several texts entitled Astrologia Theologizata and speculates on reasons for the tracts’ deviations from Paracelsus’s views. The case study of Paracelsian-Weigelian microcosmogonies underscores the centuries-long staying power of some of Paracelsus’s core theological concepts, which were both seconded by votaries and vituperatively criticized by opponents.

The Swiss natural philosopher, physician, and radical reformer Theophrastus of Hohenheim (1493–1541), known as Paracelsus, endeavoured to reconcile his various perspectives in his extensive biblical exegeses. Symbolizing this effort were the two lights of nature and the Holy Spirit, which, on one hand, explored worldly and mortal aspects of nature and, on the other hand, led to eternal life. In response to the prevailing dispute between Luther and Zwingli over the interpretation of the Eucharist, Paracelsus developed his own viewpoint, introducing (...) the concept of the new human with a renewed corporeal body. His comprehensive interpretations of the Gospel of Matthew not only addressed theology but also engaged with the perspectives of a natural philosopher, physician, and advocate of natural magic.

The study offers an analysis of the treatise Von der Pestilentz an die Statt Stertzingen (first edition 1576, ed. Michael Toxites) in the context of Paracelsus’s likely sojourn in Tyrol in 1533/1534. The article discusses Paracelsus's approach to treating plague, emphasizing practical remedies over theoretical considerations. Paracelsus offers various therapeutic interventions, including bloodletting and herbal remedies. The treatise also delves into astrological considerations, offering recommendations based on sex, age, and other factors. Despite its departure from Paracelsus’s more theoretical plague works, (...) such as Zwey Bücher von der Pestilentz vnnd jhren Zufellen and De Peste Libri tres, the Sterzing treatise is deemed authentic, reflecting a practical and utilitarian approach likely driven by Paracelsus’s attempt to secure patronage. The article underscores the importance of considering audience and genre when interpreting Paracelsus's writings, suggesting that the Sterzing treatise serves as a valuable biographical source while offering insights into his evolving medical theories.

Meteorology is not one of the most discussed topics in Paracelsus studies, although it is closely linked to both Paracelsus’ medicine and cosmology. Furthermore, it appears to be at the very core of Paracelsus’ famous matter theory of three chymical principles, mercury, sulphur and salt, known as the tria prima. By discussing prominent examples of Paracelsus’ explanations on how the tria prima operate within the stars, this article shows how the Swiss physician conceived meteorology within his own body of knowledge, (...) obviously constructed in opposition to the Aristotelian-scholastic tradition, how he based it on a peculiar interpretation of the Biblical creation story, and made it the proper laboratory of his chymical matter theory, applying it first systematically to the field of natural philosophy, especially to celestial phenomena, even before using it for his medical theory in his later writings.

Paracelsus is an extraordinarily difficult author to interpret, in part because of the seemingly elusive boundary between literal and metaphorical levels of meaning in his work. The present paper argues for a literal reading of Paracelsus, based on comments that he makes in his late Philosophia de divinis operibus & factis & de secretis naturae. The article also includes a translated chapter from one of the treatises in that work, De lunaticis.

Paracelsus was a transmutational alchemist: For most of his career, he believed that one metal could be turned into another. In an alchemical text, the De renovatione et restauratione, he explored the theoretical foundations of transmutation and hinted at recipes for bringing it about. He proposed that from plants, gems, metals, and minerals might be prepared a class of marvelous medicaments, which he called prima entia (first entities). Each primum ens had particular uses, but the entia were all supposed to (...) be able to revitalize the human body and cleanse it of disease. Certain entia could also transmute metals. The De renovatione et restauratione affirmed the metaphysical centrality, in goldmaking and medicine alike, not just of purification or alteration but of renewal and transformation. It expressed the author’s eschatological excitement at God’s works of wonder, whether within or above nature. (shrink)

The history of science is increasingly directing its attention to the diachronic examination of women's involvement within spaces dedicated to scientific inquiry. While this field of study boasts rich and meticulous historiography, delving into the sixteenth century leaves the impression of encountering either a noticeable absence of women in the realm of natural history or an underexplored period in this regard. Undoubtedly, within the Italian context of the time, the cultural milieu shaped by the Counter-Reformation further heightened the social challenges (...) faced by women.Notwithstanding these challenges, a noteworthy female figure emerges in the latter half of the sixteenth century – Francesca Fontana, the second wife of the natural history scholar Ulisse Aldrovandi (1522–1605). From an overall view of the sources, Fontana seems to assume a pivotal role in the realization of collections and works attributed to the eminent naturalist. This study aims to delineate the role played by Fontana within Aldrovandi's ‘officina naturale.’ By examining the available documents in a chronological order, my aim is to provide insights into the evolution of her education and her practical and technical skills, harnessed in the pursuit of her husband's enterprises and scholarly contributions.

This article investigates Haast’s claim that in March 1862 he independently reached the same controversial conclusion as Ramsay, that lake basins in previously glaciated regions were formed by ancient glaciers. Both men's views fuelled a passionate debate in British scientific societies. However, science historians largely ignore Haast’s contribution or imply he knew about Ramsay’s ‘theory’ before coming to a conclusion about Southern Alps lakes.To assess whether Haast independently reached that conclusion in March 1862, field records, correspondence, reports, newspaper articles, and (...) scientific publications are examined. Of significance are communications with geologists Hochstetter, Hector, and Ramsay, botanist Hooker, and physicist Tyndall. Consideration of what Haast observed in March 1862 is also critical.However, Haast's 1862 conclusion differs from Ramsay's. While Ramsay was convinced ancient glaciers scooped out rock basins, resulting in deep lakes, Haast believed ancient retreating glaciers left moraines that dammed valleys, resulting in shallow lakes. Regardless of their differences, after Haast read Ramsay’s paper in 1864, he applied Ramsay’s ‘theory’ to New Zealand’s alpine lakes and proposed an excavation process.The essence of both Ramsay’s and Haast’s conclusions has been confirmed by research in formerly glaciated regions worldwide. However, Haast’s contribution to glaciology is overlooked or underemphasized, and warrants being more widely acknowledged. (shrink)

On November 14th, 1770, the young chemist Antoine-Laurent Lavoisier (1743–1794) read his ‘Sur la nature de l’eau’ to the Académie des Sciences. Eventually published in the Académie’s journal in 1773, the two-part memoire challenged a widely held view of earlier experimenters: the transmutability of matter. Specifically, experimenters such as Jean-Baptiste Van Helmont (1580–1644), Robert Boyle (1627–1691), and Ole Borsch (1626–1690) had noted that when distilled water was heated in a glass vessel, a small amount of earthy residue remained, seemingly demonstrating (...) the transmutation of water into earth. Antoine-Laurent designed an experiment to determine whether it was really to the ‘destruction of a portion of the water that this residual earth owed its origin, or if it was to that of the glass.’ In partial agreement with Jean-Baptiste Le Roy (1720–1800), a fellow academician, Antoine-Laurent aimed to disprove the antiquated belief – the transmutation of one element into another – by using a glass vessel from the alchemist’s cabinet: the pelican.

We are all used to drawing straight lines to represent time, and above them, we plot historical events or physical or economic data. What to us is a self-evident convention, is however of an astonishingly recent date: it emerged only in the second half of the eighteenth century. To us, this late date seems paradoxical and cries out for an explanation. How else did earlier periods measure change, if not as a function of time? it will be argued that since (...) Antiquity, time was taken to measure change, and change to occur in space. ‘Our’ idea of representing time as an independent dimension would have seemed aberrant. But then, a second issue arises. Did not medieval natural philosophers employ timelines, Oresme’s diagram of the mean speed theorem being the most famous case? However, as will be shown, our interpretation of his diagram is probably wrong. This insight, in turn, takes care of a third paradox, namely Galileo’s initial inability to represent the law of free fall correctly. This article will document that the timeline first emerged in the late sixteenth century in works on chronology, made its first appearance in physics in Galileo’s diagrams, and had its general breakthrough in the eighteenth century.

Sounds are heard, sometimes even felt, but in most cases they remain unseen. This ephemeral and invisible nature of sound was already considered a problem when the science of acoustics took form in the seventeenth century. The fact that sound could not be seen was described as a significant hindrance to its understanding. But it was precisely during this time that a wide variety of sounds attracted broad scientific attention across Europe. Scholars, natural philosophers, and mathematicians investigated and experimented with (...) sound and musical instruments and developed theories of hearing. This article looks at the role of images, diagrams, and visualization techniques in late seventeenth-century acoustics, bringing together the history of sound and the history of scientific images. Focusing on water and light as the dominant analogies for sound, the article demonstrates that visualization was an important tool for thinking about sound and allowed for the circulation of theories and experiments. At the same time, the epistemic status of these images remained contested, as there was no single model that could explain the different ways sound behaves as it moves through space and that could be visualized.
