It would appear that the intrigues, of which Cardan gives so many instances, must have been the work of certain individuals, jealous of his fame and perhaps smarting under some caustic speech or downright insult, rather than of the authorities; the Senate of Bologna showed no hostility to him, but on the other hand procured for him the privileges of citizenship. While the negotiations were going on at Bologna for the further regulation of his position as a teacher, he tells a strange story how, on three or four different occasions, certain men came to him by night, in the name of the Senate and of the Judicial officers, and tried to induce him to recommend that a certain woman, who had been condemned for blasphemy, and for poisoning or witchcraft as well, should be pardoned, both by the temporal and spiritual authorities, bringing forward specially the argument that, in the sight of philosophers, such things as demons and spirits did not exist. They likewise urged him to procure the release from prison of another woman, who had not yet been condemned, because a certain sick man had died under the hands of some other doctors. They brought also a lot of nativities for him to read, as if he had been a soothsayer, and not a teacher of medicine, but he would have nothing to say to them.[217]
It is somewhat strange that Cardan should have detected no trace of the snare of the enemy in this manœuvre. Bearing in mind the character of the request made, and the fact that Cardan was by no means a persona grata to the petitioners, it seems highly probable that they might have been more anxious to draw from Cardan a profession of his disbelief in witchcraft, than to procure the enlargement of the accused persons whose cause they had nominally espoused. At this period it was indeed dangerous to be a wizard, but it was perhaps still more dangerous to pose as an avowed sceptic of witchcraft. At the end of the fifteenth century the frequency of executions for sorcery in the north of Italy had provoked a strong outburst of popular feeling against this wanton bloodshed; but Spina, writing in the interest of orthodox religion, deplores that disbelief in the powers of Evil and their manifestations, always recognized by the Church, should have led men on to profess by their action any doubt as to the truth of witchcraft. But in spite of the fulminations of men of this sort, from this time onwards the more enlightened scholars of Europe began to modify their opinions on the subject of demoniac possession, and of witchcraft in general. The first book in which the new views were enunciated was the treatise De Præstigiis Dæmonum, by Johann Wier, a physician of Cleves, published in 1563. The step in advance taken by this reformer was not a revolutionary one. He simply denied that witches were willing and conscious instruments of the malefic powers, asserting that what evil they wrought came about by reason of the delusions with which the evil spirits infected the persons said to be possessed. The devil afflicted his victims directly, and then threw the suspicion of the evil deed upon some old woman. Wier's book was condemned and denounced by the clergy—he himself was a Protestant—but the most serious counterblast against it came from the pen of Jean Bodin, the illustrious French philosopher and jurist. He held up Wier to execration as an impious blasphemer, and asserted that the welfare of Christendom must needs suffer great injury through the dissemination of doctrines so detestable as those set forth in his book.[218]
Seeing that such a spirit was dominant in the minds of men like Bodin, it will be evident that a charge of impiety or atheism might well follow a profession of disbelief, or even scepticism, as to the powers of witches or of evil spirits. A maxim familiar as an utterance of Sir Thomas Browne, "Ubi tres medici duo athei," was, no doubt, in common use in Cardan's time; and he, as a doctor, would consequently be ill-looked upon by the champions of orthodoxy, who would certainly not be conciliated by the fact that he was the friend of Cardinal Morone. This learned and enlightened prelate had been imprisoned by the savage and fanatical Paul IV., on a charge of favouring opinions analogous to Protestantism, but Pius IV., the easy-going Milanese jurisconsult, turned ecclesiastic, enlarged him by one of the first acts of his Papacy, and restored him to the charge of the diocese of Modena.
Besides enjoying at Bologna the patronage of princes of the Church like Borromeo and Morone, Cardan found there an old friend in Ludovico Ferrari, who was at this time lecturing on mathematics. He also received into his house a new pupil, a Bolognese youth named Rodolfo Sylvestro, who was destined hereafter to bring as great credit to his teacher's name in Medicine as Ferrari had already brought thereto in Mathematics. Rodolfo proved to be one of the most faithful and devoted of friends; he remained at Bologna as long as Cardan continued to live there, sharing his master's ill-fortune, and ultimately accompanied him to Rome in 1571. He gives the names of two other Bolognese students, Giulio Pozzo and Camillo Zanolino, but of all his surviving pupils he rates Sylvestro as the most gifted.
The records of Cardan's life at this period are scant and fragmentary, few events being chronicled except dreams and portents. In giving an account of one of these manifestations, which happened in September 1563, he incidentally lets light upon certain changes and vicissitudes in his own affairs. He was at this time living in an apartment in the house of the Ranucci, next door to a half-ruined palace of the Ghislieri. One night he awoke from sleep, and found that the neck-band of his shirt had become entangled with the cord by which he kept his precious emerald and a written charm suspended round his neck. He tried to disentangle the knot, but in vain, so he left the complication as it was, purposing to unravel it by daylight. He did not fall asleep; but, after lying quiet for a little, he determined to attempt once more whether he could undo the knot, when he found that everything was clear, and the stone under his armpit. "This sign showed me an unhoped-for solution of certain weighty difficulties, and at the same time proved, as I have often said elsewhere, that there must have been present something else unperceived by me. For my affairs were in this condition: my son-in-law at Milan had the administration of the scant remains of my property, and I received no rents therefrom for a whole year. My literary work was lying at the printer's, but it was not printed. Here, at Bologna, I was forced to lecture without having a fixed hour assigned to me. A crowd of enemies were intriguing against me. My son Aldo was in prison, and of little profit to me. But immediately after this portent I learned that my two chief opponents were either dying or about to retire. The question of the lecture-room was settled amicably, so that for the next year I was able to live in quiet. These two matters having come to an issue, I will next describe what came to pass with regard to the others.
"During the next July (1564), through the help of Francesco Alciati,[219] the secretary of Pope Pius IV., a man to whom I am indebted for almost every benefit I have received since 1561, I began to enjoy my own again. On August 26 I received from the printer my books all printed with the greatest care, and by reason of the dispatch of this business my income was greatly increased. The next day my chief opponent resigned his office, and left vacant a salary of seven hundred gold crowns. The only manifestation of adverse fortune left to trouble me was the conspiracy of the doctors against me, but there were already signs that this would disappear before long, and in sooth it came to an end after the lapse of another year."[220]
During this portion of his life at Bologna, Cardan seems to have lived comparatively alone, and to have spent his weary leisure in brooding over his sorrows. He began his long rambling epilogue to the De Libris Propriis, and, almost on the threshold, pours out his sorrow afresh over Gian Battista's unhappy fate. After affirming that Death must necessarily come as a friend to those whose lives are wretched, he begins to speculate whether, after all, he ought not to rejoice rather than mourn over his son's death. "Certes he is rid of this miserable life of danger and difficulty, vain, sorrowful, brief, and inconstant; these times in which the major part of the good things of the world fall to the trickster's share, and all may be enjoyed by those who are backed up by wealth or power or favour. Power is good when it is in the hands of those who use it well, but it is a great evil when murderers and poisoners are allowed to wield it. To the ill-starred, to the ungodly, and to the foolish, death is a boon, freeing them from numberless dangers, from heavy griefs, from fatal troubles, and from infamy; wherefore in such cases it ought not to be spoken of as something merely good or indifferent, but rated as the best of fortune. Shall I not declare to God (for He willed the deed), to myself, and to my surviving family, that my son's death was a thing to be desired, for God does all justly, wisely, and lovingly? He lets me stand as an example to show others that a good and upright man cannot be altogether wretched. I am poor, infirm, and old; bereaved by a cruel wrong of my best-loved son, a youth of the fairest promise, and left only with the faintest hope of any ray of future good fortune, or of seeing my race perpetuated after my death, for my daughter, who has been nine years married, is barren.
"At one time I was prosperous in every relation of life: in my friendships, in my children, and in my health. In my youth I seemed to be one raised up to realize the highest hopes. I was accustomed to all the good things—nay, to all the luxuries of life. Now I am wretched, despised, with foes swarming around me; I not only count myself miserable, I feel I am far more miserable now than I was happy aforetime. Yet I neither lose my wits nor make any boast, as my actions prove. I do my work as a teacher with my mind closely set on the matter in question, and for this reason I attract a large number of hearers. I manage my affairs better than heretofore; and, if any man shall compare the book which I have lately published with those which I wrote some time ago, he will not fail to perceive how vastly my intellect has gained in richness, in vivacity, and in purity."
Though the note of sorrow or even of despair is perceptible in these sentences, there is no sign that the virile and elastic spirit of the writer is broken. But there are manifest signs of an increasing tendency towards mental detachment from the world which had used him so ill. With the happiest of men the almost certain prospect of extinction at the end of a dozen years usually tends to foster the growth of a conviction that the world after all is a poor affair, and that to quit it is no great evil. How strongly therefore must reflections of a kindred nature have worked upon a man so cruelly tried as Cardan!
