Jerome Cardan: A Biographical Study

CHAPTER XII

At the beginning of the year 1565 Cardan had a narrow escape from death by burning, for his bed from some unknown cause caught fire twice in the same night while he was asleep. The servant was disturbed by the smoke, and having aroused his master, told him what was amiss, whereupon Cardan flew into a violent rage, for he deemed that the youth must be drunk. But he soon perceived the danger, and then they both set to work to extinguish the flames. His own description of the occurrence is highly characteristic. "Having put out the fire, I settled myself again to sleep, and, while I was dreaming of alarms, and that I was flying from some danger, it happened that either these terrifying dreams, or the fire and smoke again aroused me, and, looking around, I found that the bed was once more alight, and the greater part of it consumed. The vari-coloured coverlet, the leather hangings, and all the covering of the bed was unhurt. Thus this great alarm and danger and serious disturbance caused only a trifling loss; less than half of the bed-linen was burnt, but the blankets were entirely consumed. On the first alarm the flames burnt out twice or thrice with little smoke, and caused scarcely any damage. The second time the fire and the mishap forced me to rise just before dawn, the fire lasting altogether about seven hours."

There was naturally a warning sign to be found in this accident.[221] The smoke, Cardan said, denoted disgrace; the fire, peril and fear; the flame, a grave and pressing danger to his life. The smouldering fire signified secret plots which were to be put into execution against him by his servants while he lay in bed. And the fact that he set fire to the bed himself, denoted that he would be able to meet any coming danger alone and without assistance. The indictment against him was foreshadowed by the fire and the flames and the smoke. Poison and assault were not to be feared. Men might indeed ask questions as to what kind of danger it could be which only arose from those about him, and fell short of poison and violence. The fire, he goes on to say, signifies the Magistrate. More than once it seemed to be extinct, but it always revived. Danger seemed to threaten him less from open hostility than from the cunning flattery of foes, and from over-confidence on his own part. His books, which he had lately caused to be printed, appeared to be in grave peril, but a graver one overhung his life. He deemed that he would quit the tribunal condemned by the empty scandal of the crowd, suffering no slight loss, and worsted chiefly through putting faith in false friends, and through his own instability. On the whole, the loss would prove inconsiderable; the danger moderate, but the vexation exceedingly heavy. These results might have sprung from causes other than natural ones; but, on the other hand, such things often come about through chance. They might prove to be a warning to him to keep clear of hostile prejudice, and to make friends of those in authority, care being taken not to let himself become involved in their private affairs, and not to seek too close an acquaintance.[222]

Up to this date, Cardan, when he visited his patients, had either walked or ridden a mule. In 1562 he began to use a carriage, but this change of habit brought ill luck with it, for, in this same year, his horses ran away; he was thrown out of the vehicle, and sustained an injury to one of the fingers of his right hand, and to the right arm as well.[223] The finger soon healed, but the damage to the right arm shifted itself over to the left side, leaving the right arm sound. The foregoing details, taken chiefly from the Paralipomena (Book III. ch. xii.), are somewhat significant in respect to the serious trouble which came upon him soon afterwards.

Though he had now secured a class-room for himself, the malice of his enemies was not yet abated. Just before the end of his term, certain of them went to Cardinal Morone and told him that it would be inexpedient to allow Cardan to retain his Professorship any longer, seeing that scarcely any pupils went to listen to him. The terms Cardan used in describing this hostile movement against him,[224] rouse a suspicion that there may have been some ground for the assertion of his adversaries; but he declares that, at any rate, he had a good many pupils from the beginning of the session up to the time of Lent. He gives no clue whereby the date of this intrigue may be exactly ascertained, but it probably happened near the end of his sojourn at Bologna, because in his account of it he describes likewise the cessation of his public teaching, and makes no mention of any resumption of the same. He declares that he was at last overborne by the multitude of his foes, and their cunning plots. Under the pretence that, in seeking Cardan's removal, they were really acting for his benefit, they succeeded in bringing Cardinal Morone round to their views. Cardan's final words in dealing with this matter help to fix the date of this episode as some time in 1570. Speaking of his enemies, he writes: "Nay indeed they have given me greater leisure for the codification of my books, they have lengthened my days, they have increased my fame, and, by procuring my removal from the work which was too laborious for me, they secured for me the pleasure I now enjoy in the discovery and investigation of divers of the secrets of Nature. Therefore I constantly tell myself that I do not hate these men, nor deem them blameworthy, because they wrought me an ill turn, but because of the malignancy they had in their hearts."[225]

It is almost certain that this removal of Cardan from his office of teacher was part and parcel of a carefully-devised plot against him, and a prelude to more serious trouble in the near future. Early in April 1570 he had occasion to put into writing a certain medical opinion which was to be sent to Cardinal Morone. He describes the episode: "It chanced that one of the sheets of my manuscript fell from the table down upon the floor, and then flew by itself up to the cornice of the room, where it hung, fixed to the woodwork. Greatly amazed, I called for Rodolfo, and pointed out to him this marvel. He did not indeed see it fly up, and at that time I was ignorant as to what it might foretell, for I had no foreboding of the many ills which were about to molest me. But now I see that the meaning of this portent must have been that, after the approaching shipwreck of my fortunes, my bark would be sped along with a more favouring breeze. It was during the month following, unless I am mistaken, that, when I was once more writing a letter to Cardinal Morone, I looked for a certain powder-box which had been missing for some long time, and, when I lifted up a sheet of paper in order to powder it with dust gathered up from the floor of the room, there was the powder-box, hidden beneath the sheet. How could it have come there on the level writing-desk? This sign confirmed the hope I had already conceived of the Cardinal's wisdom and humanity; that he would plead with the Pope, the best of men, in such wise that I should find a prosperous end to my toilsome life."[226]

The blow thus foreshadowed fell on October 6, 1570, when he was suddenly arrested and put under restraint. He speaks of a bond which he gave for eighteen hundred gold crowns; and says that, while he was in hold, all his estate was administered by the civil authorities. Rodolfo Sylvestro was constantly with him during his incarceration, and on January 1, 1571, he was released, just at nightfall, and allowed to return to his own house. While he was in prison in the month of October some mysterious knockings at the door supplied him with a fulfilment and explanation of the portents lately chronicled. The knockings appeared furthermore to warn him of approaching death, and he began to bewail his misery; but, having gathered courage, he heartened himself to face his doom, which could be nothing worse than death. Young men, leaders of armies, courted death in battle to win the favour of their sovereigns; wherefore he, a decrepit old man, might surely await his end with calmness. He then wanders off into a long disquisition on the philosophy of Polybius, and forgets entirely to set down further details of his imprisonment, or to explain the cause thereof.

Pius IV. had died at the end of 1565, and had been succeeded by Michele Ghislieri, the Cardinal of Alessandria, as Pius V. Like his predecessor, the new Pope was a Milanese by birth, but in character and aims the two Popes were entirely different. Pius. V. identified himself completely with the work of the Holy Office, and straightway set in operation all its powers for the extirpation of the heretical opinions which, on account of the easy-going character of the late Pope, had made much progress in Italy, and nowhere more than in Bologna. Von Ranke, in the History of the Popes, gives an extract (vol. i. p. 97) from the compendium of the Inquisitors, which sets forth that "Bologna was in a very perilous state, because there the heretics were especially numerous; amongst them was a certain Gian Battista Rotto, who enjoyed the friendship and support of many persons of weight, such as Morone, Pole, and the Marchesa Pescara (Vittoria Colonna). Rotto made himself very active in collecting money, which he distributed amongst the poor folk of Bologna who were heretics."

It will be remembered that in 1562, while he was waiting in Milan for the appointment as Professor at Bologna, Cardan submitted his books to the Congregation of the Index for approval. He was known to be a fellow-citizen and friend of the reigning Pope: the corpus of his work had by that time reached a portentous size, wherefore it is quite possible that the official readers may have been lenient, or cursory, over their work; but when Pius V., the strenuous ascetic foe of heresy, stepped into the place of the indolent Pius IV., jurist and politician rather than Churchman, it is more than probable that certain amateur inquisitors at Bologna, fully as anxious to work Cardan's ruin as to safeguard the faith, may have busied themselves in hunting through his various works for passages upon which to base a charge of unorthodoxy. Such passages were not hard to find. There was the horoscope of Jesus Christ, which subsequently affronted the piety of De Thou. There was the passage already noticed in which he said such hard things of the Dominicans (De Varietate Rerum, 1557, p. 572). He had indeed disclaimed it, but there it stood unexpunged in the subsequent editions of the book; and, while considering this detail, it may be remarked that Pius V. began his career as a member of the Dominican Order, the practices of which Cardan had impugned. In the first and second editions of the De Subtilitate was another passage in which the tenets of Islam and the circumstances of the birth of Christ were handled in a way which caused grave scandal and offence.[227] This passage indeed was expunged in the edition of 1560. The Paralipomena were not in print and available, but what can be read in them to-day doubtless reflects with accuracy the attitude of Cardan's mind towards religious matters in 1570. Though the Paralipomena were locked in his desk, it is almost certain that the spirit with which they were inspired would have infected Cardan's brain, and prompted him to repeat in words the views on religion and a future state which he had already put on paper, for he rarely let discretion interfere with the enunciation of any opinion he favoured. In the Paralipomena are many passages written in the spirit of universalism, and treating of the divine principle as something which animates wise men alone, wise men and philosophers of every age and every clime, Aristotle being the head and chief. Plato and Socrates and the Seven Sages adorn this illustrious circle, which includes likewise the philosophers of Chaldea and Egypt. Opinions like these were no longer the passport to Papal favour or even toleration. The age of the humanist Popes was past, and the Puritan movement, stimulated into life by the active competition of the Reformers, was beginning to show its strength, so that a man who spoke in terms of respect or reverence concerning Averroes or Plato would put himself in no light peril. Thus for those of Cardan's enemies who were minded to search and listen it must have been an easy task to formulate against him a charge of heresy, specious enough to carry conviction to such a burning zealot as Pius V. This Pope, in his new regulations for the maintenance of Church discipline, requisitioned the services of physicians in the detection of laxity of religious practices, or of unsoundness. "We forbid," he says in one of his bulls, "every physician, who may be called to the bedside of a patient, to visit for more than three days, unless he receives an attestation that the sick man has made fresh confession of his sins."[228] Cardan, with his irritable temper, may very likely have treated this regulation as an unwarrantable interference with his profession, and have paid no attention to it. Again, he evidently followed Hippocrates in rejecting the supernatural origin of disease; a position greatly in advance of that held by certain of the leading physiologists of the time.[229] Thus in more ways than one he may have laid himself open to some charge of disrespect shown to religion or to the spiritual powers. The absence of any other specific accusation and the circumstances of his incarceration, taken in conjunction with the foregoing considerations, almost compel the conclusion that his arrest and imprisonment in 1570 were brought about by a charge of impiety whispered by some envious tongue which will never now be identified. The sanction given by the authorities of the Church to his writings in 1562, operated without doubt to mitigate the punishment which fell upon him, and suffered him, after due purgation of his offences, to enjoy for the residue of his days a life comparatively quiet and prosperous under the patronage of Pius V.

Though he was let out of prison he was not yet a free man. For some twelve weeks longer he remained a prisoner in his own house, the bond for eighteen hundred gold crowns having doubtless been given on this account. Almost his last reflection about his life at Bologna is one in which he records his satisfaction that all the men who plotted against him there met their death soon after their attempt, thus sharing the fate of his enemies at Milan and Pavia. If he is to be believed in this matter, the Fates, though they might not shield him from attack, proved themselves to be diligent and remorseless avengers of his wrongs. At the end of September he turned his back upon Bologna and the cold hospitality it had given him, and set forth on his last journey. He travelled by easy stages, and entered Rome on October 7, 1571, the day upon which Don John of Austria annihilated the Turkish fleet at Lepanto.

There are evidences in his later writings beyond those already cited, that Cardan's views on religion had undergone change during his sojourn at Bologna. It was the custom, even with theologians of the time, to illustrate freely from the classics, wherefore the spectacle of the names of the great men of Greek and Roman letters, scattered thickly about the pages of any book, would not prove or even suggest unorthodoxy. Cardan quotes Plato or Aristotle or Plotinus twenty times for any saint in the Calendar. He does not mention the Virgin more than once or twice in the whole of the De Vita Propria; and, in discoursing on the immortality of the soul, he cites the opinion of Avicenna, but makes no mention of either saint or father.[230] The world of classic thought was immeasurably nearer and more real to Cardan than it can be to any modern dweller beyond the Alps: to him there had been no solution of continuity between classic times and his own. When he sat down to write in the Theonoston his meditations on the death of his son, in the vain hope of reaping consolation therefrom, he invoked the golden rule of Plotinus, which lays down that the future is foreseen and arranged by the gods. Being thus arranged, it must needs be just, for God is the highest expression of justice. Against a fate thus settled for us we have no right to complain, lest we should seem to be setting ourselves into opposition to God's will. Here, although he writes in the spirit of a Christian, the authority cited is that of a heathen philosopher, and the form of his meditations is taken rather from Seneca than from father or schoolman. The devotional bias of Cardan's nature seems to have been strengthened temporarily by the terrible experiences of Gian Battista's trial and death; but in the course of his residence at Bologna a marked reaction set in, and the fervent religious outburst, in which he sought consolation during his intolerable sorrow, was succeeded by a calmer mood which regarded the necessary evils of life as transitory accidents, and death as the one and certain end of sorrow, and perhaps of consciousness as well. What he wrote during his residence in Rome he kept in manuscript; his recent experience at Bologna warned him that, living under the shadow of the Vatican with Pius V. as the ruler thereof, it behoved him to walk as an obedient son of the Church.

Cardan went first to live in the Piazza di San Girolamo, not far from the Porto del Popolo, but subsequently he lived in a house in the Via Giulia near the church of Santa Maria di Monserrato, where probably he died. He had not long been settled in Rome before he was able to add a fresh supernatural experience to his already overburdened list. In the month of August 1572 he was lying awake one night with a lamp burning, when suddenly he heard a loud noise to the right of the chamber, as if a cart laden with planks was being unloaded. He looked up, and, the door being open at the time, he perceived a peasant entering the room. Just as he was on the threshold the intruder uttered the words, "Te sin casa," and straightway vanished. This apparition puzzled him greatly, and he alludes to it again in chapter xlvii. of the De Vita Propria. Ultimately he dismisses it with the remark that the explanation of such phenomena is rather the duty of theologians than of philosophers.

With regard to matters of religious belief he seems to have taken as a rule of conduct the remark above written, and left them to the care of professional experts, for very few of his recorded opinions throw any light upon his views of the dogmas and doctrines of the Church. Whatever the tenor of these opinions may have been, he never proclaimed them definitely. Probably they interested him little, for he was not the man to keep silent over a subject which he had greatly at heart. He gave a general assent to the teaching of the Church, taking up the mental attitude of the vast majority of the learned men of his time, and expected that the Church would do all that was necessary for him in its own particular province. If he regarded Erasmus and Luther as disturbers of the faith and heretics, he did not say so, nor did he censure their activity. (Erasmus he praises highly in the opening words of the horoscope which he drew for him.—Gen. Ex., p. 496.) But he had certainly no desire to emulate them or give them his support. The world of letters and science was wide enough even for his active spirit; the world lying behind the veil he left to the exploration of those inquirers who might have a taste for such a venture. Still every page of his life's record shows how strong was his bent towards the supernatural; but the phase of the supernatural which he chose for study was one which Churchmen, as a rule, had let alone. Spirits wandering about this world were of greater moment to him than spirits fixed in beatitude or bane in the next; and accordingly, whenever he finds an opportunity, he discourses of apparitions, lamiæ, incubi, succubi, malignant and beneficent genii, and the methods of invoking them. Now that old age was pressing heavily upon him and he began to yearn for support, he sought consolation not in the ecstatic vision of the fervent Catholic, but in fostering the belief that he was in sooth under the protection of some guardian spirit like that which had attended his father and divers of the sages of old. Although he had in his earlier days treated his father's belief with a certain degree of respect and credence,[231] there is no evidence that he was possessed with the notion that any such supernatural guardian attended his own footsteps at the time when he put together the De Varietate; indeed it would seem that his belief was exactly the opposite. He writes as follows: "It is first of all necessary to know that there is one God, the Author of all good, by whose power all things were made, and in whose name all good things are brought to pass; also, that if a man shall err he need not be guilty of sin. That there is no other to whom we owe anything or whom we are bound to worship or serve. If we keep these sayings with a pure mind we shall be kept pure ourselves and free from sin. What a demon may be I know not, these beings I neither recognize nor love. I worship one God, and Him alone I serve. And in truth these things ought not to be published in the hearing of unlearned folk; for, if once this belief in spirits be taken up, it may easily come to pass that they who apply themselves to such arts will attribute God's work to the devil."[232] And in another place: "I of a truth know of no spirit or genius which attends me; but should one come to me, after being warned of the same in dreams, if it should be given to me by God, I will still reverence God alone; to Him alone will I give thanks, for any benefit which may befall me, as the bountiful source and principle of all good. And, in sooth, the spirit may rest untroubled if I repay my debt to our common Master. I know full well that He has given to me, for my good genius, reason, patience in trouble, a good disposition, a disregard of money and dignities, which gifts I use to the full, and deem them better and greater possessions than the Demon of Socrates."[233]

About the Demon of Socrates Cardan has much to say in the De Varietate. He never even hints a doubt as to the veracity and sincerity of Socrates. He is quite sure that Socrates was fully persuaded of the reality of his attendant genius, and favours the view that this belief may have been well founded. He takes an agnostic position,[234] confining his positive statement to an assertion of his own inability to realize the presence of any ghostly minister attendant upon himself. In the De Subtilitate he tells an experience of his own by way of suggesting that some of the demons spoken of by the retailers of marvels might be figments of the brain. In 1550 Cardan was called in to see a certain woman who had long been troubled with an obscure disease of the bladder. Every known remedy was tried in vain, when one day a certain Josephus Niger,[235] a distinguished Greek scholar, went to see the patient. Niger, according to Cardan's account, was quite ignorant of medicine, but he was reputed to be a skilled master of magic arts. The woman had a son, a boy about ten years old, and Josephus having handed him a three-cornered crystal, which he had with him, bade the youth secretly to look into it, and then declare, in his mother's hearing, that he could see in the crystal three very terrible demons going on foot. Then, after Josephus had whispered certain other words in the boy's ear, the boy went on to say that he beheld another demon, vastly bigger than the first, riding on horseback and bearing in his hand a three-tined fork. This monster overthrew the other demons, and led them away captive, bound with chains to his saddlebow. After listening to these words the woman rapidly got well, and Cardan, in commenting on the event, declares that she must have been cured either by the agency of the demons or by the force of the imagination, inasmuch as it would be difficult, if not impossible, to invent any other reason of her recovery.[236] In another passage of the De Subtilitate he displays judicious reserve in writing of Demons in general.[237]

During those terrible days, when his son had just died a felon's death, and when he himself was haunted by the real dangers which beset him, and almost maddened by the signs and tokens which seemed to tell of others to come, the belief which Fazio his father had nourished easily found a lodgment in his shaken and bewildered brain. In the Dialogus de Humanis Consiliis, one of the speakers tells of a certain man who is clearly meant to be Cardan himself. The speaker goes on to say that he is sure this man is attended by a genius, which manifested itself to him somewhat late in his life. "Aforetime, indeed, it had been wont to convey to him warnings in dreams and by certain noises. What greater proof of his power could there be than the cure of this man, without the use of drugs, of an intestinal rupture on the right side? If indeed it had not fared with him thus, after his son's death, he would at once have passed out of this life, whereby many and great evils might have come to pass. He was freed also from another troublesome ailment. In sooth, so many and so mighty are the wonderful things which had befallen him, that I, who am very intimate with him (and he himself thinks the same), am constrained to believe that he is attended by a genius, great and powerful and rare, and that he is not the master of his own actions. What he would have, he has not; and what he has, he would not have chosen, or even wished for. This thing causes him much trouble, but he submits when he reflects that all things are God's handiwork." The speaker ends by saying that he never heard of any others thus attended, save this man, and his father before him, and Socrates.[238]

But it is in chapter xlvii. of the De Vita Propria, which must have been written shortly before his death, that he lets the reader see most plainly how strong was the hold which this belief in a guardian spirit of his own had taken upon him. "It is an admitted truth," he writes, "that attendant spirits have protected certain men, to wit, Socrates, Plotinus, Synesius, Dion, Flavius Josephus, and myself. All of these have enjoyed prosperous lives except Socrates and me, and I, as I have said before, was at one time offered many and favourable opportunities for the achievement of happiness. But C. Cæsar the dictator, Cicero, Antony, Brutus, and Cassius were also attended by mighty spirits, albeit malignant. For a long time I have been persuaded that I too had one, but by what method it gave me intelligence as to events about to happen, I could not exactly ascertain until I reached the seventy-fourth year of my age, the season when I began to write this record of my life. I now perceive that when I was in Milan in 1557, when my genius perceived what was hanging over me—how that my son on that same evening had promised to marry Brandonia Seroni, and that he would complete the nuptials the following day—it produced in me that palpitation of the heart of which I have already made mention, a weakness known to my genius alone, a manifestation which served to simulate a trembling of the bed."

Cardan writes at length to show that the mysterious knocking which he and Rodolfo Sylvestro had heard during his imprisonment at Bologna, the peasant who entered his bed-chamber saying "Te sin casa," and divers other manifestations, going back as far as 1531—croaking of ravens, barking of dogs, and the ignition of fire-wood—must all have been brought about by the working of this powerful spirit. In 1570 there happened to him one of his everyday experiences of the presence of supernatural powers. In the middle of the night he was conscious of some presence walking about the room. It sat down beside him, and at the same time a loud noise arose from a chest which stood near. This phenomenon, he admits, might well have been the figment of a brain overburdened with thought; but suddenly his memory flies back to an experience of his twentieth year, upon which he proceeds to build a story, wild and fanciful even for his powers of imagination. "What man was it," he asks, "who sold me that copy of Apuleius when I was in my twentieth year, and forthwith went away? I indeed, at that time, had made only one essay in the literary arena, and had no knowledge of the Latin tongue; but in spite of this, and because the book had a gilded cover, I was imprudent enough to buy it. The very next day I found myself just as well versed in Latin as I am now. Moreover, almost at the same time I acquired knowledge of Greek and Spanish and French, sufficient for reading books written in these languages."

Cardan was by this time completely possessed by the belief in his attendant genius, and the flash of memory which recalled the purchase of some book or other in his youth, suggested likewise the attribution of certain mystic powers to this guardian genius, and conjured up some fanciful explanation as to the way these powers had been exercised upon himself; he, the person most closely concerned, being entirely unconscious of their operation at the time when they first affected him. This recorded belief in a gift of tongues is one of the most convincing bits of evidence to be gleaned from Cardan's writings of the insanity which undoubtedly afflicted him, at least periodically, at this crisis of his life.

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."

Powerful friends are never superfluous, and Cardan seems to have needed them in Rome as much as in Bologna. In 1573 he again hints at plots against his life, but almost immediately after recording his suspicions he goes on to suggest that his danger had arisen chiefly from his ignorance of the streets of Rome, and from the uncouth manners of the populace. "Many physicians, more cautious than myself, and better versed in the customs of the place, have come by their death from similar cause." The danger, whatever its nature, seems to have threatened him as a member of the practising faculty at Rome rather than as the persecuted ex-teacher of Pavia and Bologna. Rodolfo Sylvestro was not the only one of his former associates near him in his old age, for he notes that Simone Sosia, who had been his famulus at Pavia in 1562, was still in his service at Rome.

In reviewing the machinations of his enemies to bring about his dismissal from the Professorship at Bologna, Cardan indulges in the reflection that these men unwillingly did him good service, that is, they procured him leisure which he might use in the completion of his unfinished works, and in the construction of fresh monuments which he proposed to build up out of the vast store of material accumulated in his industrious brain. The literary record of his life in Rome shows that this was no vain saying. He was at work on the later chapters of the De Vita Propria up to the last weeks of his life; and, scattered about these, there are records of his work of correction and revising. While telling of the books he has lately been engaged with, he wanders off in the same sentence to talk of the dream which urged him to write the De Subtilitate, and of the execution of the Commentarii in Ptolomæum, during his voyage down the Loire. In 1573 he seems to have found the mass of undigested work more than he could bear to behold; for, after making extracts of such matter as he deemed worth keeping, he consigned to the flames no less than a hundred and twenty of his manuscripts.[239] Before leaving Bologna he had put into shape the Proxenata, a lengthy collection of hints, maxims, and reflections as to everyday life; he had re-edited the Liber Artis Magnæ, and had added thereto the treatise De Proportionibus, and the Regula Aliza. He also took in hand two books on Geometry, and one on Music, and this last he completed in 1574. On November 16, 1574, he records that he is at that moment writing an explanation of the more abstruse works of Hippocrates, but that he is yet far from the end of his task.

In the De Libris Propriis he gives a list of all his published works, and likewise a table of the same arranged in the order in which they ought to be read. He apologizes for the imperfect state in which some of them are left, and declares that the sight of his unfinished tasks never fails to awaken in his breast a bitter sense of resentment over that loss which he had never ceased to mourn. "At one time I hoped," he writes, "that these works would be corrected by my son, but this favour you see has been denied to me. The desire of my enemies was not to make an end of him, but of me; not by gentle means, in sooth, but by cruel open murder; to let me fall in the very blood of my son." It is somewhat remarkable that in this matter Cardan was destined to suffer a disappointment similar to that which he himself brought upon his own father by refusing to qualify himself to become the commentator on Archbishop Peckham's Perspectiva. He next gives the names of all those who had commended him in their works, and finds a special cause for gratification in the fact that, out of the long list set down, only four or five were known to him personally, and these not intimately. There is, however, another short list of censors; and of these he affirms that a certain Brodeus alone is worthy of respect. Of Buteon, who criticized the treatise on Arithmetic, he says: "Est plane stultus et elleboro indiget." Tartaglia's name is there, and he, according to Cardan, was forced to eat his words; "but he was ashamed to do what he promised, and unwilling to blot out what he had written. He went on in his wrong-headed course, living upon the labour of other men like a greedy crow, a manifest robber of other men's wealth of study; so impudent that he published as his own, in the Italian tongue, that invention for the raising of sunken ships which I had made known four years before. This he did, understanding the subject only imperfectly, and making no mention of my name. But men of real learning also attacked me: Rondeletius, and Julius Scaliger; and Fuchsius, in the proem of his book, says that my work Medicinæ Contradictiones should be avoided like deadly poison. Julius Scaliger has been fully answered in the Apologia in the Books on Subtlety."[240]

There is a passage from De Thou's History of his Own Times, affixed to all editions of the De Vita Propria,[241] in which is given a contemporary sketch of Cardan during his residence at Rome. "His whole life," De Thou writes, "has been as strange as his present manners, and he, in sooth, out of singleness of mind or frankness, has written about himself certain statements, the like of which have never before been heard of a man of letters, and these I do not feel bound to unfold to any one, let him be ever so curious. I, myself, happening to be in Rome a few years before his death, often spoke to him and observed him with astonishment as he took his walks about the city clad in strange garb. When I considered the many writings of this famous man, I could perceive in him nothing to justify his great renown. Wherefore I am all the more inclined to turn to that very acute criticism of Julius Cæsar Scaliger, who exercised his extraordinary genius in making a special examination of the treatise De Subtilitate Rerum. He, having carefully noted everywhere the unequal powers of this writer, decided that he was one who, in certain subjects, knew more than a man could know, while in others he seemed more simple than a child. In the science of Arithmetic he worked hard and made many discoveries; but he was subject to strange and excessive aberration of mind, and was guilty of the most impudent blasphemy, in that he was minded to subject to the artificial laws of the stars the Ruler of the stars Himself, for this thing he did in the horoscope of our Saviour which he drew."

Another witness of his life in Rome is François d'Amboise, a young French nobleman, who was engaged on his book De Symbolis Heroicis. He says that he saw Cardan, who was living in a spacious house, on the walls of which, in place of elegant paintings or vari-coloured tapestries, were written the words, "Tempus mea possessio."

In his later writings there are farther indications that he was wont to conjure up omens and portents chiefly at those times when he was in danger and mental distress. In the case which is given below, the omen showed itself in a season of trouble, but Cardan, in describing it later, treats it as if he were a modern scientist. The distressing memories of the imprisonment had faded, and writing in ease and security at Rome he begins to rationalize. In the dialogue between himself and his father, written shortly before his death, Fazio calls his son's attention to certain of the omens and portents already noticed; and, after discussing these, Jerome goes on to tell for the first time of another boding event which, as he affirms, distressed him even more than the loss of his office and the prohibition to publish his books. On the day of his incarceration, on two different occasions, he met a cow being driven to the slaughter-house, with much shouting and beating with sticks and barking of dogs. The explanation of this event which he puts in Fazio's mouth is entirely conceived in the spirit of rationalism. What was there to wonder at? There was a butcher's shop in the street, and animals going to slaughter would naturally be met there. Why should a man fear to meet a cow? If it had been a bull there might have been something in it. Then with regard to the shaking of a window-casement; this might easily have been occasioned by the flight of a bird.[242] He was certainly less inclined to put faith in the warnings of the stars and in the lines of his hand. His line of life was very short and irregular, intersected and bifurcated, while the rest of the lines were little thicker than hairs. In his horoscope was a certain malefic influence which threatened that his life would be cut short before his forty-fifth year. "But," he writes in the year before his death, "here I am, living at the age of seventy-five."[243] The one supernatural idea which seems to have deepened with old age and remained undisturbed to the end was his belief in his attendant genius. In what he wrote during his last years his mood was almost entirely introspective, contemplative, and didactic, yet here and there he introduces a sentence which lets in a little light from his way of life and personal affairs, and helps to show how he occupied himself, and what his humour was. He tells how one day, in 1576, he was writing about the fennel plant in his treatise De Tuenda Sanitate, a plant which he praised highly because it pleased his palate. But shortly afterwards, when he was walking one day in the Roman vegetable market, an old man, shabbily dressed, met him and dissuaded him from the use of the plant aforesaid, saying: "In Galen's opinion you may as readily meet your death thereby as by eating hemlock." "I answered that I knew well enough the difference between hemlock and fennel, but the old man said, 'Take care, I know what I am saying,' and went on murmuring something about Galen. Whereupon I went home and found in Galen a passage I had not hitherto noticed, and, having changed my former views, I added many fresh excerpts to my treatise."

Although his faith may have been shaken in the ability of the stars to govern his own fortunes, he records a case in which he himself filled the post of vates, and which came to a sudden and terrible issue. Cardan was present at a supper-party, and in the course of conversation let fall the remark, "I should like to say something, were I not afraid that my words would disturb the company," to which one of the guests replied, "You mean that you would prophesy death to one of us here present." Cardan replied, "Yes, within the present year," and in the next sentence he tells how on the first day of December in that same year a certain young man, named Virgilius, who had been present at the gathering aforesaid, died, and he sets down this event as a fulfilment of his prophecy.

But in the same chapter he lets the reader into the secret of his system of prophecy, and displays it as simply an affair of common-sense, one recommended by Aristotle as the only trustworthy method of divining future events. Cardan writes: "I used to inquire what might be the exact nature of the business in hand, and began by making myself acquainted with the character of the locality, the ways of the people, and the quality of the chief actors. I unfolded a vast number of historical instances, leading events and secret transactions as well, and then, when I had confirmed the facts set forth by my method of art, I gave my judgment thereupon."[244]

In his latter years Cardan must have been in easy circumstances. The pension from the Pope—no mention is made of its amount—and the fees he received from his patients allowed him to keep a carriage; and writing in his seventy-fifth year, he says that no fees would tempt him to join any consultation unless he should be well assured what sort of men he was expected to meet.[245]

In the Norma Vitæ Consarcinata[246] he relates how in April 1576 there were two inmates of the Xenodochium at Rome, Troilus and Dominicus. It seemed that Troilus exercised some strange and malefic influence over his companion, who was taken with fever. He got well of this, but only to fall into a dropsy, which despatched him in a week. Shortly before his death, at the seventh hour, he cried out to two Spaniards who were standing by the bed that he had suffered such great torture from the working of Troilus, and that he was dying therefrom. "Therefore," he cried, "in your presence I summon him with my dying words to appear before God's tribunal, that he may give an account of all the evil he has wrought against me." On the following day there came a messenger from Corneto, a few miles from Rome, saying that Troilus, who was sojourning there, had fallen sick. The physician inquired at what hour, and the messenger said it was at seven o'clock, a day or two ago. He lay ill some days, an unfavourable case, but not a desperate one, and one night shortly afterwards at seven o'clock, the top of the mosquito curtains fell, and he died at exactly the same hour as Dominicus.

He tells another long story of an adventure which befell him in May 1576. One day he was driving in his carriage in the Forum, when he remembered that he wanted to see a certain jeweller who lived in a narrow alley close by. Wherefore he told his coachman, a stupid fellow, to go to the Campo Altoviti, and await him there. The coachman drove off apparently understanding the order; but, instead of going to the place designated, went somewhere else; so Cardan, when he set about to find his carriage, sought in vain. He had a notion that the man had gone to a spot near the citadel, so he walked thither, encumbered with the thick garments he had put on as necessary for riding in the carriage. Just then he met a friend of his, Vincenzio, a Bolognese musician, who remarked that Cardan was not in his carriage as usual. The old man went on towards the citadel, but saw nothing of the carriage; and now he began to be seriously troubled, for there was naught else to be done but to go back over the bridge, and he was wearied with long fasting and his heavy clothes. He might indeed have asked for the loan of a carriage from the Governor of the castle; but he was unwilling to do this, so having commended himself to God, he resolved to use all his patience and prudence in finding his way back. He set out, and when he had crossed the bridge, he entered the banking-house of the Altoviti to inquire as to the alteration in the rate of exchange on Naples, and there sat down to rest. While the banker was giving him this information, the Governor entered the place, whereupon Cardan went out and there he found his carriage, the driver having been informed by Vincenzio, whom he had met, of the mistake he had made. Cardan got into the carriage, and while he was wondering whether or not he had better go home and break his fast, he found three raisins in his pocket, and thus made a fortunate ending of all his difficulties.

All this reads like a commonplace chapter of accidents; but the events recorded did not present themselves to Cardan in this guise. He sits down to moralize over the succession of momentary events: his meeting with Vincenzio; Vincenzio's meeting with the driver, and directions given to the man to drive to the money-changers'; the presence of the Governor, his exit from the bank, his consequent meeting with the carriage, and his discovery of the raisins, seven occurrences in all, any one of which, if it had happened a little sooner or a little later, would have brought about great inconvenience, or even worse. He does not deny that other men may not now and then encounter like experiences, but the experiences of other men were not fraught with such momentous crises, nor did they foreshadow so many or grave dangers.

The chronicling of this episode and the fanciful coincidence of the deaths of Dominicus and Troilus may be taken as evidence that his idiosyncrasies were becoming aggravated by the decay of his faculties. Writing on October 1, 1576, he makes mention of the various testaments he had already made, and goes on to say that he had resolved to make a new and final disposition of his goods. He would fain have let his property descend to his immediate offspring, but with a son like Aldo this was impossible, so he left all to Gian Battista's son, who would now be a youth about eighteen years of age, Aldo getting nothing. He desired, for reasons best known to himself, that all his descendants should remain in curatela as long as possible, and that all his property should be held on trust; if the issue of his body should fail, then the succession should pass in perpetuity to his kinsfolk on the father's side. He desired that his works should be corrected and printed, and that, if heirs failed entirely, his house at Bologna should pass to the University, and be styled, after his family, Collegium Cardanorum.

There is no authentic record of the exact date of Cardan's death. De Thou, in writing the record of 1576, says that if Cardan's life had been prolonged by three days he would have completed his seventy-fifth year. As Cardan's birthday was September 24, 1501, this would fix his death on September 21, 1576. The exact figures given by De Thou are: "eodem, quo prædixerat, anno et die, videlicet XI. Kalend. VIII.," and he adds by way of information that a belief was current at the time that Cardan, who had foretold how he would die on this day and in this year, had abstained from food for some days previous to his death in order to make the fatal day square with the prophecy.

But the details which Cardan himself has set down concerning the last few weeks of his life are inconsistent with the facts chronicled by De Thou. In the De Vita Propria, chapter xxxvi., Cardan records how on October 1, 1576, he set to work to make his last will and testament, wherefore if credit is to be given to his version rather than to that of De Thou, he was alive and active some days after the date of his death as fixed by the chronicler. In cases where the record of an event of his early life given in the De Vita Propria differs from an account of the same in some contemporary writing, the testimony of the De Vita Propria may justly be put aside; but in this instance he was writing of something which could only have happened a few days past, and the balance of probability is that he was right and De Thou wrong. Bayle notices this discrepancy, and in the same paragraph taxes De Thou with a mistake of which he is innocent. He states that De Thou placed the date of Cardan's death in 1575, whereas the excerpt cited above runs: "Thuanus ad annum MDLXXVI., p. 136, lib. lxii. tom. 4. Romæ magni nominis sive Mathematicus, sive Medicus Hieronymus Cardanus Mediol. natus hoc anno itidem obiit."

No mention is made of the disease to which Cardan finally succumbed. Had his frame not been of the strongest and most wiry, it must have gone to pieces long before through the havoc wrought by the severe and continuous series of ailments with which it was afflicted; so it seems permissible to assume that he died of natural decay. His body was interred in the church of Sant Andrea at Rome, and was subsequently transferred to Milan to be deposited finally under the stone which covered the bones of his father in the church of San Marco. This tomb, which Jerome had erected after Fazio's death, bore the following inscription:

FACIO  CARDANO

1.C.

Mors fuit id quod vixi: vitam mors dedit ipsa,
Mens æterna manet, gloria tuta quies.

Obiit anno MDXXIV. IV. Kalend. Sept. anno Ætatis LXXX.
