The difficulties that beset Columbus are well known. How he was hounded both in Portugal and in Spain by the clergy; and even after his discovery of America, the Papacy still maintained its theory of the flatness of the earth and the nonsense of the antipodes. Pope Alexander VI and Pope Julius II attempted to settle the disputes between Spain and Portugal by drawing some remarkable maps that may still be found; but no one dares to disturb the quiet of the ridiculous bulls that the popes issued on this dispute.
In 1519 Magellan made his famous voyage and proved the earth to be round and that men actually lived in the antipodes. But the force of ecclesiastical stultification was so great, as it is today, that men still believed the opposite view for two hundred years after the voyage of Magellan.
CHAPTER X
RELIGION AND CHEMISTRY AND PHYSICS
The establishment of Christianity, beginning a new evolution of theology, arrested the normal development of the physical sciences for more than 1500 years. The work begun by Aristotle and carried on to such a high state of relative perfection by Archimedes, was stifled by the early Christians. An atmosphere was then created in which physical science could not grow. The general belief derived from the New Testament was that the end of the world was at hand, and the early Church Fathers poured contempt upon all investigators of the science of nature.
Then, too, for science there was established an insurmountable barrier, in that the most careful inductions of science from ascertained facts must conform to the view of nature given in the myth and legends of the Bible. For 1500 years science was forced to confine itself to a system of deducing scientific truth from scriptural texts. It was the accepted word of the clergy that science was futile and dangerous which led to the discrediting of Roger Bacon's works.
In 1163 Pope Alexander III forbade the study of physics to all ecclesiastics, which of course, in that age, meant prohibition of all such scientific studies to the only persons likely to follow them.
Roger Bacon was first to practice extensively the experimental method of science. Through his researches the inventions of clocks, lenses, and the formula for extracting phosphorus, manganese, and bismuth were brought to light. Bitterly attacked by the clergy, he attempted to defend himself by stating that much which was ascribed to demons resulted from natural means. This statement but added fuel to the flame. For in 1278 the authorities of the Franciscan Order assembled at Paris, solemnly condemned Bacon's teachings, and the general of the Franciscans, Jerome of Ascoli, afterwards Pope, threw him into prison, where he remained for fourteen years. At the age of eighty, he was released from prison declaring, "Would that I had not given myself so much trouble for the love of science."
