Show Summary Details


The relationship between Johannes Kepler and Galileo has a pronounced historiographical profile, in part because both were followers of Nicolaus Copernicus. The failures of that relationship would have heavy consequences for seventeenth-century heavenly science and natural philosophy. By the following decade, Kepler and Galileo were already engaging one another within the discursive space created by the second-generation Copernicans and the practitioners of the contested via media. This chapter examines how those differences evolved in the decade prior to the telescopic discoveries and the elliptical astronomy. It discusses Galileo and the science of the stars in the Pisan period, Galileo and the Wittenberg and Uraniborg-Kassel networks, Galileo's exchange with Jacopo Mazzoni, Gian Vincenzo Pinelli's circle and Edmund Bruce's letters to Kepler, Giordano Bruno's execution, William Gilbert's project for a magnetical philosophy, Galileo's first run-in with the Inquisition, and Kepler's continuing search for astrology's foundations.
