For several decades, historians have realized the limitations of analysing the historical past of science as a mere succession of theories. One of the most stimulating messages that the reinvention of the discipline has launched is that although there are obvious intellectual elements that promote the development and progress of science, there are also social, economic, and institutional aspects to consider. The history of science is no longer just a history of scientific ideas and theories, but also a history of (...) institutions, communities, spaces, objects, and practices as well as a history of the complex interaction among all these dimensions. Accompanying this new panorama is a broad consensus among scholars to accept that major social changes have inexorably some impact on scientific practice and vice versa. This premise, now widespread, is especially relevant to the history of early modern science and the question of its roots because it has allowed the introduction of new agents and spaces previously excluded from the domain of scientific development. In other words, this enriched perspective has multiplied both the processes of knowledge construction and the arenas in which these processes were undertaken. More specifically, historical research is no longer limited to spaces traditionally linked to the construction of science; it now embraces less orthodox ones. Within this broadened field of inquiry, practical knowledge and the objects of material culture have come to occupy a central place. This special issue explores how the new directions in which the history of science has expanded have a direct impact on the study of Iberian science in the Atlantic world. (shrink)

This article suggests that institutional workshops of assay were significant experimental sites in early modern London. Master assayers at Goldsmiths’ Hall on Foster Lane, in the heart of the city, and at the Royal Mint, in the Tower, made trials to determine the precious-metal content of bullion, plate and coinage. The results of their metallurgical experiments directly impacted upon the reputations and livelihoods of London's goldsmiths and merchants, and the fineness of coin and bullion. Engaged in the separation and transformation (...) of matter, assayers and the affairs of their workshops were also a curiosity for those interested in the secrets of nature. Making use of a wide-ranging body of sources, including institutional court minutes, artisanal petitions, mercantile guidebooks, recipe books and natural-philosophical treatises, this article uncovers a complex culture of metropolitan expertise. We first examine the workshop spaces in which assayers undertook their professional activities, and their secretive corporate cultures. We turn next to the manuscript culture through which assayers codified and communicated knowledge, ‘secrets’ and techniques to broader urban audiences. Finally, we assess exchanges and tensions between assayers and the wider community of Londoners engaged in scientific knowledge production and dissemination. (shrink)

In 2017 a clock from the collection of the Mathematisch-Physikalischer Salon in Dresden was dismantled. This clock had been made around 1767 by Johann Gottfried Köhler (1745–1800), who was then in...

Edgar Zilsel's famous thesis, which argues that modern experimental science was born from the union of artisans and intellectuals in the 16th century, received little support when Zilsel proposed it in the 1940s. In recent years, however, with the turn toward social and cultural history of science, the “Zilsel Thesis” has undergone something of a revival as historians rethink the relevance of artisanal knowledge for the history of early modern science. This essay looks at the Zilsel Thesis in a global (...) setting – specifically a colonial Iberian setting – and argues for its relevance in framing natural history, medicine, and the impact of science on everyday life. Using the examples of corn, quina, and cochineal, this essay argues that the agronomic, chemical, and entomological knowledge accumulated over generations of practice by indigenous practitioners was in fact artisanal knowledge that was passed on to European intellectuals in “global trading zones” to become part of the Western scientific patrimony.

The practices of Galenic pharmacy that dominated the Western pharmaceutical tradition throughout the medieval and early modern periods generally eschewed methods of alchemical processing and the use of high heat. A unique 10th-century Arabic pharmaceutical treatise, the Kitab al Tasrif by al-Zahrāwī/Abulcasis, however, discussed thermo-chemical techniques of distillation, calcination, and sublimation at length and would go on to have a major impact on Galenic pharmacy. It included recipes, for example, for two highly important distilled substances – rosewater and Philosophers' Oil (...) – that were copied and revised in Latin texts from the later Middle Ages and early modern Spanish formularies. By the end of the 16th century, these recipes had formed the basis for two new categories of distilled medicines – distilled waters and distilled oils – in Galenic pharmacy. Their inclusion in the Galenic formulary indicates that apothecaries in the Latin West were familiar with and indeed practicing thermo-chemical operations during the medieval and early modern periods.
