This special issue brings to the attention of the scholarly community some of the common features and some of the subtle, but important, differences between Francis Bacon's and Giovan Battista Della Porta's ways of dealing with the reading, selecting, enacting, and recording of recipes. Focusing on questions of genre, intellectual and material context, strategies of research, and strategies of performing recipes, the four papers of this special issue address two major issues. First, they shed new light on the relationship between (...) Della Porta's Magia naturalis and Francis Bacon's Sylva sylvarum. Second, they show that in the recording of their experimental practices, Bacon and Della Porta depart from the traditional “recipe format” and discover new avenues of experimental research. (shrink)

This paper investigates the emergence, in the second part of the 17th century, of a new body of experimental knowledge dealing with the chemical transformations of water taking place in plants. We call this body of experimental knowledge a “chemical history of vegetation.” We show that this chemical natural history originated, in terms of recipes and methods of investigation, in the works of Francis Bacon and that it was constructed in accordance with Bacon's precepts for putting together natural and experimental (...) histories. Our paper covers a wide array of experimental investigations, carried out by people with different backgrounds, theoretical assumptions, and metaphysical allegiances (Thomas Browne, Robert Sharrock, Robert Boyle, Nehemiah Grew, John Beale, and John Evelyn). We claim that, despite their differences, these naturalists had a lot in common. First, they treated plants as laboratories of chemical investigation. Second, they used the experiments with plants to develop tools, hypotheses, and operational concepts, which travelled from one naturalist to the other, even when their respective explanatory vocabularies were widely different. Third, we show that some of them also manifested an interest in defining and clarifying the limits and structure of this new body of experimental knowledge, displaying, thus, a certain disciplinary unity.

The relationship between Francis Bacon's Sylva sylvarum and Giovan Battista Della Porta's Magia naturalis has previously been discussed in terms of sources and borrowings in the literature. More recently, it has been suggested that one can read these two works as belonging to a common genre: as collections of recipes or books of secrets. Taking this as a framework, in this paper I address another type of similarity between these two works, one that can be detected by looking at the (...) methods of reading, research, and enacting and recording recipes one can find in Bacon and Della Porta. I show that essential to the two approaches was the complex interplay of practices associated with enacting recipes, and that these influenced the ways in which Della Porta and Bacon recorded their experiments. Creative manipulation of the recipes transformed them into something new. In the case of Della Porta's second edition of the Magia naturalis, this new format is something I call “technologies,” that is, ways of recording the enacting of recipes with the intention to ensure repeatability and predictability of results. In the case of Bacon, the enactment aims at something different: to display and “bring to light” the hidden motions and processes of nature. (shrink)

Early modern study of plants blossomed in a network of observation, exchanges, collaborations, and epistolary discussions. Following Baconian methodology, Dutch scholars combined the labor of listing and describing plants with botanical experimentation. This empirical approach was a suitable context for Descartes, who exchanged information and performed observations on plants in collaboration with Dutch experimenters. In this article, I focus on (1) the reception of a few botanical experiments of Bacon’s Sylva Sylvarum in Huygens and Reneri, with whom Descartes was in (...) contact, and (2) Descartes’ collaboration with Reneri. While performing observations on plants together, Reneri acquired Descartes’ theoretical framework (as it arises in his disputations) and influenced the latter with a Baconian approach to the study of living nature. This combination of experimental knowledge and a theoretical framework shaped a Cartesian study of plants, as it later surfaced in Regius and ultimately paved the way to a modern science of plants.
