This article investigates several discussions of “chemistry,” understood as an analysts’ category referring to theories and practices dealing with the structure and transformation of matter. By reading these texts (a treatise defending kīmiyāʾ by al-Fārābī, the famous passage from Ibn Sīnā’s Shifāʾ on transmutation, Ibn Taymiyyah’s fatwā…[Read more]

The term “alchemy,” born out of early modern professional polemics among chemists, is problematic as a historical category. The present article shifts away from asking what pre-modern alchemy “really” was, to asking how medieval scholars writing in Greek and Arabic thought about the practice of treating and combining naturally occurring substan…[Read more]

The early modern use of vegetal terms to explain the origin and growth of ores was widespread in mining industry, alchemy, and natural philosophy. In the writings of authors from many different backgrounds, mineral veins were often described as ‘trees’ which moved upwards, bore fruits, and underwent a life cycle. Accordingly, the existence in ore…[Read more]

This article examines a little-known and unstudied alchemical treatise, The Epistle on Alchemy (al-Risāla fī l-ṣināʿa) attributed to Aristotle, purportedly translated from Syriac into Arabic by the Nestorian bishop ʿAbdīshōʿ bar Brīkhā (d. 1318). In particular, I investigate the Epistle’s discourse on the concealment and revelation of alchemical…[Read more]

New evidence on scholarly patronage under the Roman empire can be garnered by analyzing the descriptions of learned magoi in several texts from the second to the fourth century CE. Since a common use of the term magos connoted flatterer-like figures (kolakes), it is likely that the figures of “learned sorcerers” found in texts such as Luc…[Read more]

The chair of chymiatria created at the University of Marburg was among the earliest academic initiatives aiming to integrate chymistry into the medical curriculum. If its practical applications in pharmacy and its relationship with patronage have been examined by historians, the theoretical part of the chymiatria programme still remains to be…[Read more]

Centred on the eclectic sources of early modern neo-atomistic medicine, this chapter examines the physiological theory of German alchemist Daniel Sennert (1572–1637) and Dutch engineer Isaac Beeckman (1588–1637). Both university-trained physicians, they followed Galenic medicine in explaining the structure and functioning of the human body at the…[Read more]

This chapter examines the use of vegetal analogy in late Renaissance physiology through the case of the German physician Daniel Sennert (1572–1637). It is centered on Sennert’s explanation of generation, in particular the transmission of life through the vegetative soul within the seed, as developed in his early works on medicine and alchemy, the…[Read more]

Hylomorphism is a recent term in the history of philosophy and the sciences. What was used from Antiquity to the early modern period was the terminological couple “matter” and “form.” According to the Aristotelian physics, matter and form are indissociable principles which constitute the elements and preside over the generation and destruc…[Read more]

The genesis and growth of minerals, as well as the existence in ore veins of such organic features as ‘seeds’, ‘matrices’, and ‘nourishment’, remained central and recurrent issues for natural philosophers, technicians, alchemists and practitioners throughout early modern Europe. By providing an overview of the main themes, voices, and concurrent…[Read more]

In the history of early modern science, the German physician Andreas Libavius (Halle, Saxony, c.1550–Coburg, Bavaria, 1616) is known for having promoted the institutionalization of alchemy in the academic sphere along with the creation of laboratories and instruments. Libavius was also remarkable for his extended network of scholarly friends and f…[Read more]

This article analyzes the famous tenth-century Greek alchemical codex Marcianus graecus 299, and in particular its first quire, considering the structure and significance of the manuscript as a whole.

This paper studies transmutation theory as found in the texts attributed to Zosimus of Panopolis,“the philosopher Synesius,” and “the philosopher Olym-piodorus of Alexandria.” It shows that transmutation theory (i.e. a theory explain-ing the complete transformation of substances) is mostly absent from the work attributed to these three authors…[Read more]

By the end of the sixteenth century, many Jesuit colleges had become centers of excellence all over Europe for such disciplines as mathematics, astronomy, hydraulics, and mechanics. Not a few members of the order provided influential contributions to science: in the case of the study of waters, the inquisitive eye of Jesuits took part in the l…[Read more]

Since its first attempts to understand natural phenomena, early modern science devoted great attention to the problematic issue of the origin of springs. This essay examines the lively debate that emerged from the studies on fresh water during the years spanning from the mid-sixteenth century to the early eighteenth. By focusing on the…[Read more]

Since the beginning of his scientific activity the physician and naturalist Antonio Vallisneri
(1661-1730) devoted many studies to the Earth sciences. In those years his interest focused
particularly on the features of mineral kingdom and its relationship with spring water. The first
observations date back to the last decade of XVII century,…[Read more]
