Heresy is treason to the Church, but Bruno could not see how spiritual dogma could cover the facts of Physical Science, since new facts were constantly being discovered, and the material universe could only be understood by being studied. He was too innocent to comprehend that a vast majority of the people believed that popes, cardinals and priests knew everything, and that when any branch of knowledge was questioned it placed the priests in doubt. Certainly the Church has not opposed Science--she has only opposed heresy. But the curious fact is that advancing Science has usually been to the Church heretical. When Bruno opposed anything that the priests taught, he opposed the Church. He was warned to leave Rome--his life was in danger. He fled to Geneva, the home of Calvin. Here he thought, surely, he could speak and write as he chose. But alas! Protestantism cared even less about Science than did the monks, and "heresy" to John Calvin was quite as serious a matter as it was to Calvin's competitor, the Pope of Rome. The Protestants of Geneva gave Bruno scant attention; they had never heard of Copernicus, and the movements of the stars were as nothing to them, since the world was soon to come to an end. The learned men were even then making mathematical calculations, based on the prophecies of the Old Testament, as to how soon the general destruction would take place. Bruno sought to argue them out of their childishness, with the result that he got himself marked as an infidel and a dangerous man. From Geneva he went to Lyons, then to Paris, where his personality made itself felt, and he was given a hearing at the University. Here he remained for several years, when he went to England, arriving there in Fifteen Hundred Eighty-four, the same year that a rustic by the name of William Shakespeare, from Stratford, reached London. Whether they ever met is doubtful. Bruno spoke five languages, and his polite accomplishments afforded him an immediate entry into the best circles of society. He was entertained at the home of Sir Philip Sidney, and afterward carried on an extensive correspondence with this prince of gentlemen. Greville presented Bruno to Queen Elizabeth, who invited him to lecture at the Court on his favorite theme. This he did, and it is quite probable that the noble lords and ladies left "calls" so they could be awakened when the lecture was over and congratulate the speaker of the evening on his effort. At Oxford there were disputations where Bruno's faultless Latin impressed the pedants much more than did his argument, so they offered him a position as Professor of Languages, but this he smilingly declined, excusing himself on the grounds that he had important business on the Continent: and he had. Already they were collecting fagots for his benefit.
