Abstract
All too often, historians of the ‘Galileo Affair’ fail to recognize the dynamic – indeed, tumultuous – nature of the political landscape surrounding Galileo’s condemnation and the events leading to it. This was a landscape rent by the Thirty Years War, which dominated the affairs of Europe’s rulers, including Galileo’s patrons. In fact, Galileo’s publication of the Dialogo in 1632 could not have come at a more ill-advised moment: in the aftermath of the battle of Breitenfeld, the nadir of Catholicism in Germany. Blame for this calamitous defeat fell on Galileo’s most important protector, Pope Urban VIII. Thus, when Galileo’s book appeared, Galileo became a useful example by which Urban could consolidate his severely weakened position. The Pope carefully crafted the public image of an unusual trial, at the expense of his old friend. Certainly, Galileo’s trial resulted from profound intellectual and political tensions that pervaded early modern Rome, but it must also be understood in light of the European exigencies of the moment.
