Note 254 — Chapter XIII · THE RISE OF MODERN FREETHOUGHT—(Continued)

It was with Galileo that there began the practical application of the Copernican theory to astronomy, and, indeed, the decisive demonstration of its truth. With him, accordingly, began the positive rejection of the Copernican theory by the Church; for thus far it had never been officially vetoed—having indeed been generally treated as a wild absurdity. Almost immediately after the publication of Galileo’s Sidereus Nuncius (1610) his name is found in the papers of the Inquisition, with that of Cremonini of Padua, as a subject of investigation.254 The juxtaposition is noteworthy. Cremonini was an Aristotelian, with Averroïst leanings, and reputed an atheist;255 and it was presumably on this score that the Inquisition was looking into his case. At the same time, as an Aristotelian he was strongly opposed to Galileo, and is said to have been one of those who refused to look through Galileo’s telescope.256 Galileo, on the other hand, was ostensibly a good Catholic; but his discovery of the moons of Jupiter was a signal confirmation of the Copernican theory, and the new status at once given to that made a corresponding commotion in the Church. Thus he had against him both the unbelieving pedants of the schools and the typical priests.
