"Io vorrei poter doventare un Antigalileo" : Ludovico delle Colombe e la nova del 1604

Ludovico delle Colombe was among the most tenacious adversariesof Galileo Galilei. A staunch defender of Aristotelian natural philosophy, he sought byevery means - even invoking the authority of Scripture - to oppose Copernicanism,which Galileo openly endorsed with the publication of the Sidereus nuncius in 1610.This article aims to investigate the distinctive features of delle Colombe's Aristotelian­ism prior to 1610, when he had not yet defined himself as "an AntiGalileo". To thisend, the analysis has focuses on his two works on the nova of 1604, the Discorso of1606 against Raffaello Gualterotti's thesis, and the Risposte piacevoli e curiose of1608, addressed to Alimberto Mauri, probably a pseudonym used by Galileo. It hastherefore been established that, contrary to what was previously assumed, his shift toan antiGalilean form of Aristotelianism cannot be attributed to the existence of a Florentine circle opposing Galileo before the publication of the Sidereus nuncius.
