Bacon as a member of the Franciscan Order found himself confronted with the rule requiring his superiors’ permission to publish any work. However, Pope Clement IV, a Frenchman, had the requirement lifted so far as Bacon was concerned by personally communicating with him and asking him to publish his studies. When that Pope was Cardinal Guy le Gros de Foulques (or Foulquois), the Papal Delegate in England, he had been impressed with Bacon’s scholarship. Following the Pope’s command, Bacon set out to do the job. After some difficulty in obtaining money for pens and copyists, the three great works, _Opus Majus_, _Minus_ and _Tertium_ (1267–68) were completed in the almost unbelievable time of 18 months. These, together with his short book, “Concerning the marvelous power of art and nature and the ineffectiveness of magic”--also known as “Letter concerning the secret works of art and nature”--are his best known writings. As soon as his first book was completed Bacon sent it off to the Pope in care of his friend, John of Paris. Unfortunately, Pope Clement IV died within a year of receiving Bacon’s book and no official papal action was taken in connection with his scientific opinions. Bacon continued to teach, study and experiment at Oxford where he held for a time the office of Chancellor. Some say he was eventually imprisoned; the record is not clear. The most interesting part of Bacon’s work, so far as motion picture prehistory is concerned, is contained in his letter “On the Power of Art and Nature and Magic.” It is in this work that Bacon speaks of the many wonderful devices he knows about and which would be in service in the future. Here we read of self-propelled vehicles, under-water craft, flying machines, gun-powder (the idea of which probably came from the East), lenses, microscopes, telescopes. Bacon claimed that he had seen all these wonderful things with the exception of the flying machine. But even this did not leave him at a loss, for he tells us that he has seen drawings by a man who has it all worked out on paper! In that book of Bacon there is also the theory of going westward to India--the idea that later resulted in the discovery of America. The idea, therefore, was not original with Christopher Columbus. Bacon deserves great credit, for his views at least had a direct influence. His statements were used without credit by Pierre d’Ailly in his _Imago Mundi_, published in 1480. We know Columbus consulted this work, for he quoted a passage in his letter to Ferdinand and Isabella when seeking financial support for the voyage. And it was the very passage of Bacon, stolen by d’Ailly, which Columbus used to drive home his arguments with the King and Queen of Spain.
