This contribution uses the career and writings of Juan Solórzano Pereira (1575–1655) to probe the relationship between mercury, governance, and the obligations of individuals to the early modern Iberian state. It focuses specifically on two terms often employed in the context of practical governance—“bien público” (public good) and “hacienda” (treasury)—by placing Solórzano Pereira’s 1647 Politica Indiana and administrative documents generated during his tenure at the mercury mine of Huancavelica (modern Peru) in dialogue. Read in tandem, these texts reveal that Solórzano (...) Pereira articulated the relationship between mercury, the bien público, and the hacienda through comparisons between mining and agriculture, a conception of nature as an agential force, and period understandings of the “common.” While historians of practical governance often dismiss appeals to the bien público and the hacienda as hollow rhetoric, this essay reveals that the terms were important for period actors in conceptualizing the distribution of labor and materials.

This article examines how Jesuit Gabriele Beati taught the subject of sunspots in two textbooks commemorating his teaching of natural philosophy and mathematics at the Collegio Romano. Whereas Beati defended the incorruptibility of the heavens in his natural philosophical course, he argued that sunspots were located on the face of the sun itself and generated and corrupted like terrestrial clouds in his mathematical one. While it may be tempting to attribute these different presentations to censorship practices within the Jesuit Order, (...) they are best understood as the result of disciplinary distinctions and scholarly practices shared widely by scholars across Europe.

This contribution examines the role of diagrams in early modern pedagogy. It begins with an analysis of images from the 1632 Dialogo and 1638 Discorsi. I claim that Galileo often employed images in a pedagogical context, illustrating to readers through his dialogue how he may have used images in his own teaching. Building on the work of previous historians, I argue that a classification of Galileo’s images should include not only heuristic images and images used for virtual witnessing, but also (...) pedagogical images designed to illustrate to the reader (or student) how to reach conclusions about a given question. I then turn to the way Galileo’s readers at the University of Pisa employed Galileo’s images in their own teaching. I argue that Galileo’s readers employed his images in their own works in ways which reflected their training and the genre in which they wrote and taught. (shrink)

SummaryA heretofore overlooked response to Galileo's 1638 Discorsi is described by examining two extant copies of the text which are heavily annotated. It is first demonstrated that these copies contain annotations made by Seth Ward and Sir Christopher Wren. This article then examines one feature of Ward's and Wren's responses to the Discorsi, namely their decision to re-write several of Galileo's geometrical demonstrations into the language of symbolic algebra. It is argued that this type of active reading of period mathematical (...) texts may have been part of the regular scholarly and pedagogical practices of early modern British mathematicians like Ward and Wren. A set of Appendices contains a transcription and translation of the analytical solutions found in these annotated copies. (shrink)

Galileo’s 1638 Two New Sciences, a canonical text of early modern science, is analyzed as a window into period practices of mixed-mathematical reading. Galileo’s depiction of reading reflects common scholarly practices, including those of summarizing, commenting, repeated study, and an interest in mathematical diagrams. With this text, Galileo also attempted to shape his readers’ practices, inciting them to approach topical-based reading strategies with care and to use experiment and experience to validate the written word. It is suggested that the concern (...) with reading practices exhibited in the text derived from circumstances surrounding Galileo’s 1633 condemnation. (shrink)

Summary This contribution examines the history of the production of Galileo's 1638 Discorsi. It provides a detailed narrative of Galileo's and his collaborators' attempts to secure a printer for the work. Through analysis of surviving correspondence, manuscripts, and proof copies, I examine in greater detail the working methods of Galileo and his correspondents, particularly in regards to the text's images. This examination serves as a boon to historians of the early modern book, as Galileo's surviving correspondence provides an unusually rich (...) record of his and his collaborators' activities. I show that the volume was produced through a collaborative process in which Galileo's correspondents played a significant role in determining the work's layout, images, and content. The study thus complements the claims of previous scholars, who have argued for the collaborative nature of much of Galileo's intellectual work. It also offers a new perspective on the Discorsi, a text which is often studied for insight into Galileo's process of discovery. (shrink)

This contribution demonstrates the benefits of a transatlantic history of early modern mining that encompasses both a cross-pollination of approaches and a critical reexamination of the field’s underlying assumptions. It applies to Álvaro Alonso Barba’s 1640 El arte de los metales conceptual frameworks developed by historians of early modern European mining, by scholars of labor and science in the colonial Andes, and by theorists of reader reception and scholarly practice. This analysis offers a revised understanding of Pamela Long’s model of (...) the “trading zone” as a vision of knowledge production promoted by elite Europeans and shaped by the dialogic model of knowledge production taught at European universities. Parallels between Barba and the German humanist and metallurgical author Georg Agricola (1494–1555) underscore the applicability of these findings with respect to Barba for early modern mining more generally.
