And so the errors of science, the prejudices of the superstitious, the excitement of the religious, and the cupidity of the rich and powerful, all concurred to propagate the faults of the cabal at the close of the Middle Ages. Never were there seen so many sorcerers, astrol-ogists, and alchemists; never were prophecies, visions, and prodigies so common. Whatever happened, it was pretended{142} that it had been announced by some previous sign, or that it was a revelation of the future. This particular kind of folly persisted in Germany longer than in any other part of the world. Even Martin Luther seemed to share many of the cabalistic views, and his alleged struggle with the devil, his adventure with the inkstand, and so on, contributed much to spread them, and were, perhaps, the most prominent illustrations of their general acceptance. Surely, these were the Dark Ages. Jerome Cardan was born at Pavia in 1501. His life, like that of Agrippa, was one of vicissitude and inconsistency. Being the idol of his mother and the detestation of his father produced a peculiar effect upon his character. When he began to study he made rapid progress, and at the age of twenty-two was able to discuss publicly all questions. About two years later he received his doctor's hat. He practiced medicine in various places until he was thirty-three, and was then made professor of mathematics at Milan. He occupied this position but two years, then traveled in Germany, France, and England, and returning to Italy was imprisoned for debt in Bologna, and finally obtained a pension from the pope, in Rome, where he died in 1556. He was a man of great attainments and sagacity; his literary style was dignified, and, if he had not developed such a taste for the marvelous, such inconceivable credulity and superstition, and such vanity and boasting, he would have been a remarkable character in his age. Leibnitz said of him: "Notwithstanding his faults, Cardan was a great man and, without his defects, would have been incomparable." He wrote extensively on philosophy, mathematics, and medicine. Sometimes he admitted to his writings the most absurd statements of visions, etc., and again affirmed that he had never devoted himself to cabalistic art, blamed those who practiced it, and jeered at those who believed in it. He wrote extensively on chiromancy. For his own follies and misfortunes he apologized,{143} attributing them all to the influences of the stars. [Illustration: 0163]
