Copernicus’s De revolutionibus and Girolamo Fracastoro’s Homocentrica were both addressed to Pope Paul III. Their dedicatory letters represent a rhetorical exercise in advocating an astronomical reform and an attempt to obtain the papal favour. Following on from studies carried out by Westman and Barker & Goldstein, this paper deals with cultural, intellectual and scientific motives of both texts, and aims at underlining possible relations between them, such as that Copernicus knew of Fracastoro’s Homocentrica, and that at least part of the (...) rhetorical strategy laid out in De revolutionibus’s dedicatory letter can be read as a sophisticated response to Fracastoro’s arguments.Keywords: Copernicus; Fracastoro; Paul III; History of astronomy; Patronage.

This paper examines the production and circulation of astrological prognostications regarding the illness and death of kings, princes, and popes in the Italian Renaissance . The distribution and consumption of this type of astrological information was often closely linked to the specific political situation in which they were produced. Depending on the astrological techniques used , and the media in which they appeared these prognostications fulfilled different functions in the information economy of Renaissance Italy. Some were used to legitimise the (...) rule of a political leader, others to do just the opposite. Astrological prorogations and interrogations were often used to plan military and political strategies in case of the illness or death of a political leader, while astrological prognostications were generally written to promote certain political leaders while undermining others. While certainly often partisan to this game, astrologers, for their part, worked within a very well established tradition that gave authority to their forecasts. This paper argues that, as indicators of deeper political tensions otherwise not always explicitly manifest, these prognostications are privileged sources of information providing a better understanding of the political history of the period.

In separate reviews of The Copernican Question published in the Summer 2012 issue of this journal, Noel Swerdlow and John Heilbron find little that meets their approval while failing to provide readers with a full and accurate summary of the book’s major claims and arguments.* The reviewers engage in an exercise in deconstructive surgery, essentially breaking down and reconstituting the work into separate studies. Swerdlow, who devotes most of his twenty-five page treatment to chapter 3 (with brief side-glances at the (...) introduction, chapters 1, 8, and 11), leaves the impression that my book is almost entirely about Copernicus. Heilbron, who confines himself mostly to what I have to say about Galileo, identifies a .. (shrink)

Drawing on a half century of scholarship, of Polish studies of Copernicus and Cracow University, and of Copernicus's sources, this book offers a comprehensive re-evaluation of Copernicus's achievement, and explains his commitment to the ...

Girolamo Cardano was an Italian doctor, natural philosopher, and mathematician who became a best-selling author in Renaissance Europe. He was also a leading astrologer of his day, whose predictions won him access to some of the most powerful people in sixteenth-century Europe. In Cardano's Cosmos, Anthony Grafton invites readers to follow this astrologer's extraordinary career and explore the art and discipline of astrology in the hands of a brilliant practitioner.Renaissance astrologers predicted everything from the course of the future of humankind (...) to the risks of a single investment, or even the weather. They analyzed the bodies and characters of countless clients, from rulers to criminals, and enjoyed widespread respect and patronage. This book traces Cardano's contentious career from his first astrological pamphlet through his rise to high-level consulting and his remarkable autobiographical works. Delving into astrological principles and practices, Grafton shows how Cardano and his contemporaries adapted the ancient art for publication and marketing in a new era of print media and changing science. He maps the context of market and human forces that shaped Cardano's practicesâe"and the maneuvering that kept him at the top of a world rife with patronage, politics, and vengeful rivals.Cardano's astrology, argues Grafton, was a profoundly empirical and highly influential art, one that was integral to the attempts of sixteenth-century scholars to understand their universe and themselves.

My aim is to make some comments on the ontology of the correspondence theory of truth. First I shall give reasons for rejecting a Platonic view of propositions. This motivates locating propositions in the world. I then present a version of Russell’s theory of truth, which if it locates propositions anywhere locates them in the world. I consider some of the advantages of this theory, not least among being that it does not need facts as entities.
