[235] Cardan alludes to Niger in _De Varietate_, p. 641: "Referebat aliquando Josephus Niger harum rerum maxime peritus, daemonem pueris se sub forma Christi ostendisse, petiisseque ut adoraretur." [236] _De Subtilitate_, p. 530. [237] "Nolim ego ad trutinam haec sectari, velut Porphyrius, Psellus, Plotinus, Proclus, Jamblicus, qui copiose de his quae non videre, velut historiam natae rei scripserunt."--_De Subtilitate_, p. 540. [238] _Opera_, tom. i. 672. CHAPTER XIII AFTER the accusation brought against him at Milan in 1562, Cardan had been prohibited from teaching or lecturing in that city, and similar disabilities had followed his recent imprisonment at Bologna. At Rome no duties of this kind awaited him, so he had full time to follow his physician's calling after taking up his residence there. He records the cure of a noble matron, Clementina Massa, and of Cesare Buontempo, a jurisconsult, both of whom had been suffering for nearly two years. The circumstances of his retirement from Bologna would not affect his reputation as a physician, and he seems to have had in Rome as many or even more patients than he cared to treat; and in writing in general terms concerning his successes as a healer, he says: "In all, I restored to health more than a hundred patients, given up as incurable in Milan, in Bologna, and in Rome." Of all the friends Cardan had in this closing period of his life, none was more useful or benevolent than Cardinal Alciati, who, although he had been secretary to Pius IV., contrived to retain the favour of his successor. This piece of good fortune Alciati owed to the protection of Carlo Borromeo, who had been his pupil at Pavia, and had procured for him from Pius IV. a bishopric, a cardinal's hat, and the secretaryship of Dataria. Another of Cardan's powerful friends was the Prince of Matellica, of whom he speaks in terms of praise inflated enough to be ridiculous, were it not for the accompanying note of pathos. After celebrating the almost divine character of this nobleman, his munificence and his superhuman abilities, he goes on: "What could there be in me to win the kindly notice of such a patron? Certainly I had done him no service, nor could he hope I should ever do him any in the future, I, an old man, an outcast of fortune, and prostrated by calamity. In sooth, there was naught about me to attract him; if indeed he found any merit in me, it must have been my uprightness."
