Words and works in the history of alchemy.

This essay considers the implications of a shift in focus from ideas to practices in the history of alchemy. On the one hand, it is argued, this new attention to practice highlights the diversity of ways that early modern Europeans engaged alchemy, ranging from the literary to the entrepreneurial and artisanal, as well as the broad range of social and cultural spaces that alchemists inhabited. At the same time, however, recent work has demonstrated what most alchemists shared-namely, a penchant for reading, writing, making, and doing, all at the same time. Any history of early modern alchemy, therefore, must attend to all of these practices, as well as the interplay among them. In this sense, alchemy offers a model for thinking and writing about early modern science more generally, particularly in light of recent work that has explored the intersection of scholarly, artisanal, and entrepreneurial forms of knowledge in the early modem period.
