The year after Galileo issued his book, Porta put out a work much more pretentious, called "Natural Magic." In this book Porta does not claim that magicians all have supernatural powers; but he goes on to prove how they deceive the world by the use of their peculiar apparatus, and intimates that they sometimes sell their souls to the Devil, and then are positively dangerous. He dives deep into science, history and his own imagination to prove things. The man was no fool--he constructed a kaleidoscope that showed an absolute, geometrical symmetry, where in fact there was only confusion. He showed how, by the use of mirrors, things could be made big, small, tall, short, wide, crooked or distorted. He told of how magicians, by the use of Galileo's Tube, could show seven stars where there was only one; and he even made such a tube of his own and called the priests together to look through it. He painted stars on the glass, and had men look at the heavens. He even stuck a louse on the lens and located the beast in the heavens, for the benefit of a doubting Cardinal. It was all a joke, but at the time no sober, sincere man of Science could argue him down. He owned "bum" telescopes that proved all kinds of things, to the great amusement of the enemies of Galileo. The intent of Porta was to expose the frauds and fallacies of Galileo. Porta also claimed that he had seen telescopes by which you could look over a hill and around a corner, but he did not recommend them, since by their use things are often perceived that were not there. And so we see why the priests positively refused to look through Galileo's Tube, or to believe anything he said. Porta, and a few others like him, showed a deal more than Galileo could and offered to locate stars anywhere on order. Galileo had much offended these priests by his statements that the Bible did not contain the final facts of Science, and now they were getting even with a vengeance. It was all very much like the theological guffaw that swept over Christendom when Darwin issued his "Origin of Species," and Talmage and Spurgeon set their congregations in a roar by gently sarcastic references to monkey ancestry. * * * * * Amid the general popping of theological small-arms, Galileo moved steadily forward. If he had many enemies he surely had a few friends. As he once had proved more than Pisa could digest, so now he was bringing to the surface of things more truth than Padua could assimilate. Venice too was getting uncomfortable. Even the Doge said, in reply to an enthusiastic admirer of Galileo, "Your master is not famous: he is merely notorious."
