Yielding at last to the entreaties of Cardinal Schonberg, Archbishop of Capua, and Bishop Giese of Culm he entrusted his work for publication to one of his pupils, Rheticus, professor at Wittenberg, but the opposition of the Lutheran professors made it impossible to bring out the book in that city. It was finally published under the editorship of Osiander at Nurnberg in 1543. In the preface to the work Osiander made considerable changes out of deference to the views of Luther and Melanchthon, the most important of which was that he referred to the system of Copernicus as an hypothesis that might or might not be true. The work, /De Revolutionibus Orbium Coelestium/ was dedicated to Pope Paul III. The principal opposition to the novel views of Copernicus came from the side of the Lutheran theologians, and it was only years later, when feeling was aroused by the controversy regarding Galileo, that any suspicion of unorthodoxy was directed against Copernicus by Catholic writers. Needless to say Copernicus died as he had lived, a devoted Catholic, fully convinced that he had done good service for religion as well as for science. Galileo Galilei (1564-1642) was remarkable from a very early age for his abilities as a student of mathematics and mechanics. Indeed it was in these subjects and not in astronomy that he achieved his most brilliant and most lasting successes. He taught at Pisa and Padua, and was afterwards employed at the court of the Grand Duke of Tuscany. In 1609 he perfected the telescope by means of which he was enabled to make observations of the heavenly bodies, and from these observations and discoveries he was led to the conclusion that the heliocentric system as advocated by Copernicus was the only one scientifically tenable. He came to Rome, where he was welcomed by the Pope and the cardinals, and set up his telescope in the Vatican gardens (1611). At first Galileo's views excited no great opposition, but owing to the imprudent propaganda carried on by some of his own friends, notably by the Carmelite, Foscarini, a violent controversy broke out in which the scientific side of the theory was almost completely forgotten. Against Galileo it was contended that his system contradicted the Scripture, which spoke of the sun standing still in its course at the prayers of Josue, and that it was, therefore, inadmissible. At the time in Italy the ecclesiastical authorities were markedly conservative and hostile to innovations, particularly as there was then a strong party in Italy, of whom Paul Sarpi may be taken as a typical example, who were liberal and Lutheran in their tendencies and sympathies. Had the discussion been confined to learned circles no notice might have been taken of it, but once an appeal was made to the masses of the people it was almost inevitable that Galileo should have been denounced to the Inquisition.
