Jerome Cardan Part 1

Jerome Cardan.

by William George Waters.

PREFACE

No attempt is made in the following pages to submit to historical treatment the vast and varied ma.s.s of printed matter which Cardan left as his contribution to letters and science, except in the case of those works which are, in purpose or incidentally, autobiographical, or of those which furnish in themselves effective contributions towards the framing of an estimate of the genius and character of the writer. Neither has it seemed worth while to offer to the public another biography constructed on the lines of the one brought out by Professor Henry Morley in 1854, for the reason that the circ.u.mstances of Cardan's life, the character of his work, and of the times in which he lived, all appeared to be susceptible of more succinct and h.o.m.ogeneous treatment than is possible in a chronicle of the pa.s.sing years, and of the work that each one saw accomplished. At certain junctures the narrative form is inevitable, but an attempt has been made to treat the more noteworthy episodes of Cardan's life and work, and the contemporary aspect of the republic of letters, in relation to existing tendencies and conditions, whenever such a course has seemed possible.

Professor Morley's book, _The Life of Girolamo Cardano, of Milan, physician_, has been for some time out of print. This industrious writer gathered together a large quant.i.ty of material, dealing almost as fully with the more famous of the contemporary men of mark, with whom Cardan was brought into contact, as with Cardan himself. The translations and a.n.a.lyses of some of Cardan's more popular works which Professor Morley gives are admirable in their way, but the s.p.a.ce they occupy in the biography is somewhat excessive. Had sufficient leisure for revision and condensation been allowed, Professor Morley's book would have taken a high place in biographical literature. As it stands it is a noteworthy performance; and, by reason of its wide and varied stores of information and its excellent index, it must always prove a valuable magazine of _memoires pour servir_ for any future students who may be moved to write afresh, concerning the life and work of the great Milanese physician.

An apology may be needed for the occurrence here and there of pa.s.sages translated from the _De Vita Propria_ and the _De Utilitate ex Adversis capienda_, pa.s.sages which some readers may find too frequent and too lengthy, but contemporary opinion is strongly in favour of letting the subject speak for himself as far as may be possible. The date and place of Cardan's quoted works are given in the first citation therefrom; those of his writings which have not been available in separate form have been consulted in the collected edition of his works in ten volumes, edited by Spon, and published at Lyons in 1663.

The author desires to acknowledge with grat.i.tude the valuable a.s.sistance in the way of suggestion and emendation which he received from Mr. R.C.

Christie during the final revision of the proofs.

JEROME CARDAN

CHAPTER I

LIKE certain others of the ill.u.s.trious personages who flourished in his time, Girolamo Cardano, or, as he has become to us by the unwritten law of nomenclature, Jerome Cardan, was fated to suffer the burden and obloquy of b.a.s.t.a.r.dy.[1] He was born at Pavia from the illicit union of Fazio Cardano, a Milanese jurisconsult and mathematician of considerable repute, and a young widow, whose maiden name had been Chiara Micheria, his father being fifty-six, and his mother thirty-seven years of age at his birth. The family of Fazio was settled at Gallarate, a town in Milanese territory, and was one which, according to Jerome's contention, could lay claim to considerable antiquity and distinction. He prefers a claim of descent from the house of Castillione, founding the same upon an inscription on the apse of the princ.i.p.al church at Gallarate.[2] He a.s.serts that as far back as 1189 Milo Cardano was Governor of Milan for more than seven years, and according to tradition Franco Cardano, the commander of the forces of Matteo Visconti,[3] was a member of the family. If the claim of the Castillione ancestry be allowed the archives of the race would be still farther enriched by the name of Pope Celestine IV., G.o.dfrey of Milan, who was elected Pope in 1241, and died the same year.

Cardan's immediate ancestors were long-lived. The sons of Fazio Cardano, his great-grandfather, Joanni, Aldo, and Antonio, lived to be severally ninety-four, eighty-eight, and eighty-six years of age. Of these Joanni begat two sons: Antonio, who lived eighty-eight years, and Angelo, who reached the age of eighty-six. To Aldo were born Jacopo, who died at seventy-two; Gottardo, who died at eighty-four; and Fazio, the father of Jerome, who died at eighty.[4]

Fazio, albeit he came of such a long-lived stock, and lived himself to be fourscore, suffered much physical trouble during his life. On account of a wound which he had received when he was a youth, some of the bones of his skull had to be removed, and from this time forth he never dared to remain long with his head uncovered. When he was fifty-nine he swallowed a certain corrosive poison, which did not kill him, but left him toothless.

He was likewise round-shouldered, a stammerer, and subject to constant palpitation of the heart; but in compensation for these defects he had eyes which could see in the dark and which needed not spectacles even in advanced age.

Of Jerome's mother little is known. Her family seems to have been as tenacious of life as that of Fazio, for her father Jacopo lived to be seventy-five years of age. Of his maternal grandfather Jerome remarks that he was a highly skilled mathematician, and that when he was about seventy years of age, he was cast into prison for some offence against the law. He speaks of his mother as choleric in temper, well dowered with memory and mental parts, small in stature and fat, and of a pious disposition,[5] and declares that she and his father were alike in one respect, to wit that they were easily moved to anger and were wont to manifest but lukewarm and intermittent affection for their child. Nevertheless they were in a way indulgent to him. His father permitted him to remain in bed till the second hour of the day had struck, or rather forbade him to rise before this time--an indulgence which worked well for the preservation of his health. He adds that in after times he always thought of his father as possessing the kindlier nature of the two.[6]

It would seem from the pa.s.sage above written, as well as from certain others subsequent, that Jerome had little affection for his mother; and albeit he neither chides nor reproaches her, he never refers to her in terms so appreciative and loving as those which he uses in lamenting the death of his harsh and tyrannical father. In the _Geniturarum Exempla_[7]

he says that, seeing he is writing of a woman, he will confine his remarks to saying that she was ingenious, of good parts, generous, upright, and loving towards her children. Perhaps the fact that his father died early, while his mother lived on for many years, and was afterwards a member of his household--together with his wife--may account for the colder tone of his remarks while writing about her. She was the widow of a certain Antonio Alberio,[8] and during her marriage had borne him three children, Tommaso, Catilina, and Joanni Ambrogio; but when Jerome was a year old all three of these died of the plague within the s.p.a.ce of a few weeks.[9] He himself narrowly escaped death from the same cause, and this attack he attributes to an inherited tendency from his mother, she having suffered from the same disease during her girlhood. There seems to have been born to Fazio and Chiara another son, who died at birth.[10]

Jerome Cardan was born on September 24, 1501, between half-past six o'clock and a quarter to seven in the evening. In the second chapter of his autobiography he gives the year as 1500, and in _De Utilitate_, p.

347, he writes the date as September 23, but on all other occasions the date first written is used. Before he saw the light malefic influences were at work against him. His mother, urged on no doubt by the desire to conceal her shame, and persuaded by evil counsellors, drank a potion of abortive drugs in order to produce miscarriage,[11] but Nature on this occasion was not to be baulked. In recording the circ.u.mstances of his birth he writes at some length in the jargon of astrology to show how the celestial bodies were leagued together so as to mar him both in body and mind. "Wherefore I ought, according to every rule, to have been born a monster, and, under the circ.u.mstances, it was no marvel that it was found necessary to tear me from the womb in order to bring me into the world.

Thus was I born, or rather dragged from my mother's body. I was to all outward seeming dead, with my head covered with black curly hair. I was brought round by being plunged in a bath of heated wine, a remedy which might well have proved hurtful to any other infant. My mother lay three whole days in labour, but at last gave birth to me, a living child."[12]

The sinister influences of the stars soon began to manifest their power.

Before Jerome had been many days in the world the woman into whose charge he had been given was seized with the plague and died the same day, whereupon his mother took him home with her. The first of his bodily ailments,--the catalogue of the same which he subsequently gives is indeed a portentous one,[13]--was an eruption of carbuncles on the face in the form of a cross, one of the sores being set on the tip of the nose; and when these disappeared, swellings came. Before the boy was two months old his G.o.dfather, Isidore di Resta of Ticino, gave him into the care of another nurse who lived at Moirago, a town about seven miles from Milan, but here again ill fortune attended him. His body began to waste and his stomach to swell because the nurse who gave him suck was herself pregnant.[14] A third foster-mother was found for him, and he remained with her till he was weaned in his third year.

When he was four years of age he was taken to Milan to be under the care of his mother, who, with her sister, Margarita, was living in Fazio's house; but whether she was at this time legally married to him or not there is no evidence to show. In recording this change he remarks that he now came under a gentler discipline from the hands of his mother and his aunt, but immediately afterwards proclaims his belief that the last-named must have been born without a gall bladder, a remark somewhat difficult to apply, seeing he frequently complains afterwards of her harshness. It must be remembered, however, that these details are taken from a record of the writer's fifth year set down when he was past seventy.[15] He quotes certain lapses from kindly usage, as for instance when it happened that he was beaten by his father or his mother without a cause. After much chastis.e.m.e.nt he always fell sick, and lay some time in mortal danger.

"When I was seven years old my father and my mother were then living apart--my kinsfolk determined, for some reason or other, to give over beating me, though perchance a touch of the whip might then have done me no harm. But ill-fortune was ever hovering around me; she let my tribulation take a different shape, but she did not remove it. My father, having hired a house, took me and my mother and my aunt to live with him, and made me always accompany him in his rounds about the city. On this account I, being taken at this tender age with my weak body from a life of absolute rest and put to hard and constant work, was seized at the beginning of my eighth year with dysentery and fever, an ailment which was at that time epidemic in our city. Moreover I had eaten by stealth a vast quant.i.ty of sour grapes. But after I had been visited by the physicians, Bernabo della Croce and Angelo Gyra, there seemed to be some hope of my recovery, albeit both my parents, and my aunt as well, had already bewept me as one dead.

"At this season my father, who was at heart a man of piety, was minded to invoke the divine a.s.sistance of San Girolamo (commending me to the care of the Saint in his prayers) rather than trust to the working of that familiar spirit which, as he was wont to declare openly, was constantly in attendance upon him. The reason of this change in his treatment of me I never cared to inquire. It was during the time of my recovery from this sickness, that the French celebrated their triumph after defeating the Venetians on the banks of the Adda, which spectacle I was allowed to witness from my window.[16] After this my father freed me of the task of going with him on his rounds. But the anger of Juno was not yet exhausted; for, before I had fully recovered my health, I fell down-stairs (we were then living in the Via dei Maini), with a hammer in my hand, and by this accident I hurt the left side of my forehead, injuring the bone and causing a scar which remains to this day. Before I had recovered from this mishap I was sitting on the threshold of the house when a stone, about as long and as broad as a nut, fell down from the top of a high house next door and wounded my head just where my hair grew very thickly on the left side.

"At the beginning of my tenth year my father changed this house, which had proved a very unlucky one for me, for another in the same street, and there I abode for three whole years. But my ill luck still followed me, for my father once more caused me to go about with him as his _famulus_, and would never allow me on any pretext to escape this task. I should hesitate to say that he did this through cruelty; for, taking into consideration what ensued, you may perchance be brought to see that this action of his came to pa.s.s rather through the will of Heaven than through any failing of his own. I must add too that my mother and my aunt were fully in agreement with him in his treatment of me. In after times, however, he dealt with me in much milder fas.h.i.+on, for he took to live with him two of his nephews, wherefore my own labour was lessened by the amount of service he exacted from these. Either I did not go out at all, or if we all went out together the task was less irksome.

"When I had completed my sixteenth year--up to which time I served my father constantly--we once more changed our house, and dwelt with Alessandro Cardano next door to the bakery of the Bossi. My father had two other nephews, sons of a sister of his, one named Evangelista, a member of the Franciscan Order, and nearly seventy years of age, and the other Otto Cantone, a farmer of the taxes, and very rich. The last-named, before he died, wished to leave me his sole heir; but this my father forbad, saying that Otto's wealth had been ill gotten; wherefore the estate was distributed according to the directions of the surviving brother."[17]

This, told as nearly as may be in his own words, is the story of Cardan's birth and childhood and early discipline, a discipline ill calculated to let him grow up to useful and worthy manhood. It must have been a wretched spring of life. Many times he refers to the hard slavery he underwent in the days when he was forced to carry his father's bag about the town, and tells how he had to listen to words of insult cast at his mother's name.[18] Like most boys who lead solitary lives, unrelieved by the companions.h.i.+p of other children, he was driven in upon himself, and grew up into a fanciful imaginative youth, a lover of books rather than of games, with an old head upon his young shoulders. After such a training it was only natural that he should be transformed from a nervous hysterical child into an embittered, cross-grained man, profligate and superst.i.tious at the same time. Abundant light is thrown upon every stage of his career, for few men have left a clearer picture of themselves in their written words, and nowhere is Cardan, from the opening to the closing scene, so plainly exhibited as in the _De Vita Propria_, almost the last work which came from his pen. It has been a.s.serted that this book, written in the twilight of senility by an old man with his heart cankered by misfortune and ill-usage, and his brain upset by the dread of real or fancied a.s.saults of foes who lay in wait for him at every turn, is no trustworthy guide, even when bare facts are in question, and undoubtedly it would be undesirable to trust this record without seeking confirmation elsewhere.

This confirmation is nearly always at hand, for there is hardly a noteworthy event in his career which he does not refer to constantly in the more autobiographic of his works. The _De Vita Propria_ is indeed ill arranged and full of inconsistencies, but in spite of its imperfections, it presents its subject as clearly and effectively as Benvenuto Cellini is displayed in his own work. The rough sketch of a great master often performs its task more thoroughly than the finished painting, and Cardan's autobiography is a fragment of this sort. It lets pa.s.s in order of procession the moody neglected boy in Fazio's ill-ordered house, the student at Pavia, the youthful Rector of the Paduan Gymnasium, plunging when just across the threshold of life into criminal excess of Sardanapalean luxury, the country doctor at Sacco and afterwards at Gallarate, starving amongst his penniless patients, the University professor, the famous physician for whose services the most ill.u.s.trious monarchs in Europe came as suppliants in vain, the father broken by family disgrace and calamity, and the old man, disgraced and suspected and hara.s.sed by persecutors who shot their arrows in the dark, but at the same time tremblingly anxious to set down the record of his days before the night should descend.

Until he had completed his nineteenth year Jerome continued to dwell under the roof which for the time being might give shelter to his parents. The emoluments which Fazio drew from his profession were sufficient for the family wants--he himself being a man of simple tastes; wherefore Jerome was not forced, in addition to his other youthful troubles, to submit to that _execrata paupertas_ and its concomitant miseries which vexed him in later years. To judge from his conduct in the matter of Otto Cantone's estate, Fazio seems to have been as great a despiser of wealth as his son proved to be afterwards. His virtue, such as it was, must have been the outcome of one of those hard cold natures, with wants few and trifling, and none of those tastes which cry out daily for some new toy, only to be procured by money. The fact that he made his son run after him through the streets of Milan in place of a servant is not a conclusive proof of avarice; it may just as likely mean that the old man was indifferent and callous to whatever suffering he might inflict upon his young son, and indisposed to trouble himself about searching for a hireling to carry his bag. The one indication we gather of his worldly wisdom is his dissatisfaction that his son was firmly set to follow medicine rather than jurisprudence, a step which would involve the loss of the stipend of one hundred crowns a year which he drew for his lectures.h.i.+p, an income which he had hoped might be continued to a son of his after his death.[19]

Amidst the turmoil and discomfort of what must at the best have been a most ill-regulated household, the boy's education was undertaken by his father in such odds and ends of time as he might find to spare for the task.[20] What with the hardness and irritability of the teacher, and the peevishness inseparable from the pupil's physical feebleness and morbid overwrought mental habit, these hours of lessons must have been irksome to both, and of little benefit. "In the meantime my father taught me orally the Latin tongue as well as the rudiments of Arithmetic, Geometry, and Astrology. But he allowed me to sleep well into the day, and he himself would always remain abed till nine o'clock. But one habit of his appeared to me likely to lead to grave consequences, to wit the way he had of lending to others anything which belonged to him. Part of these loans, which were made to insolvents, he lost altogether; and the residue, lent to divers persons in high places, could only be recovered with much trouble and no little danger, and with loss of all interest on the same. I know not whether he acted in this wise by the advice of that familiar spirit[21] whose services he retained for eight-and-thirty years. What afterwards came to pa.s.s showed that my father treated me, his son, rightly in all things relating to education, seeing that I had a keen intelligence. For with boys of this sort it is well to make use of the bit as though you were dealing with mules. Beyond this he was witty and diverting in his conversation, and given to the telling of stories and strange occurrences well worth notice. He told me many things about familiar spirits, but what part of these were true I know not; but a.s.suredly tales of this sort, wonderful in themselves and artfully put together, delighted me marvellously.

"But what chiefly deserved condemnation in my father was that he brought up certain other youths with the intention of leaving to them his goods in case I should die; which thing, in sooth, meant nothing less than the exposure of myself to open danger through plots of the parents of the boys aforesaid, on account of the prize offered. Over this affair my father and my mother quarrelled grievously, and finally decided to live apart.

Whereupon my mother, stricken by this mental vexation, and troubled at intervals with what I deem to have been an hysterical affection, fell one day full on the back of her neck, and struck her head upon the floor, which was composed of tiles. It was two or three hours before she came round, and indeed her recovery was little short of miraculous, especially as at the end of her seizure she foamed much at the mouth.

"In the meantime I altered the whole drift of this tragedy by a pretended adoption of the religious life, for I became for a time a member of the mendicant Franciscan brotherhood. But at the beginning of my twenty-first year[22] I went to the Gymnasium at Pavia, whereupon my father, feeling my absence, was softened towards me, and a reconciliation between him and my mother took place.

"Before this time I had learnt music, my mother and even my father having secretly given me money for the same; my father likewise paid for my instruction in dialectics. I became so proficient in this art that I taught it to certain other youths before I went to the University. Thus he sent me there endowed with the means of winning an honest living; but he never once spake a word to me concerning this matter, bearing himself always towards me in considerate, kindly, and pious wise.

"For the residue of his days (and he lived on well-nigh four more years) his life was a sad one, as if he would fain let it be known to the world how much he loved me.[23] Moreover, when by the working of fate I returned home while he lay sick, he besought, he commanded, nay he even forced me, all unwilling, to depart thence, what though he knew his last hour was nigh, for the reason that the plague was in the city, and he was fain that I should put myself beyond danger from the same. Even now my tears rise when I think of his goodwill towards me. But, my father, I will do all the justice I can to thy merit and to thy paternal care; and, as long as these pages may be read, so long shall thy name and thy virtues be celebrated.

He was a man not to be corrupted by any offering whatsoever, and indeed a saint. But I myself was left after his death involved in many lawsuits, having nothing clearly secured except one small house."[24]

Fazio contracted a close intimacy with a certain Galeazzo Rosso, a man clever as a smith, and endowed with mechanical tastes which no doubt helped to secure him Fazio's friends.h.i.+p. Galeazzo discovered the principle of the water-screw of Archimedes before the description of the same, written in the books of the inventor, had been published. He also made swords which could be bent as if they were of lead, and sharp enough to cut iron like wood. He performed a more wonderful feat in fas.h.i.+oning iron breast-plates which would resist the impact of red-hot missiles. In the _De Sapientia_, Cardan records that when Galeazzo perfected his water-screw, he lost his wits for joy.

Fazio took no trouble to teach his son Latin,[25] though the learned language would have been just as necessary for the study of jurisprudence as for any other liberal calling, and Jerome did not begin to study it systematically till he was past nineteen years of age. Through some whim or prejudice the old man refused for some time to allow the boy to go to the University, and when at last he gave his consent he still fought hard to compel Jerome to qualify himself in jurisprudence; but here he found himself at issue with a will more stubborn than his own. Cardan writes: "From my earliest youth I let every action of mine be regulated in view of the after course of my life, and I deemed that as a career medicine would serve my purpose far better than law, being more appropriate for the end I had in view, of greater interest to the world at large, and likely to last as long as time itself. At the same time I regarded it as a study which embodied the n.o.bler principles, and rested upon the ground of reason (that is upon the eternal laws of Nature) rather than upon the sanction of human opinion. On this account I took up medicine rather than jurisprudence, nay I almost entirely cast aside, or even fled from the company of those friends of mine who followed the law, rejecting at the same time wealth and power and honour. My father, when he heard that I had abandoned the study of law to follow philosophy, wept in my presence, and grieved amain that I would not settle down to the study of his own subject. He deemed it the more salutary discipline--proofs of which opinion he would often bring forward out of Aristotle--that it was better adapted for the acquisition of power and riches; and that it would help me more efficiently in restoring the fortunes of our house. He perceived moreover that the office of teaching in the schools of the city, together with its accompanying salary of a hundred crowns which he had enjoyed for so many years, would not be handed on to me, as he had hoped, and he saw that a stranger would succeed to the same. Nor was that commentary of his destined ever to see the light or to be ill.u.s.trated by my notes. Earlier in life he had nourished a hope that his name might become ill.u.s.trious as the emendator of the 'Commentaries of John, Archbishop of Canterbury on Optics and Perspective.'[26] Indeed the following verses were printed thereanent:

'Hoc Cardana viro gaudet domus: omnia novit Unus: habent nullum saecula nostra parem.'

"These words may be taken as a sort of augury referring rather to certain other men about to set forth to do their work in the world, than to my father, who, except in the department of jurisprudence (of which indeed rumour says that he was a master), never let his mind take in aught that was new. The rudiments of mathematics were all that he possessed, and he gathered no fresh knowledge from the store-houses of Greek learning. This disposition in him was probably produced by the vast mult.i.tude of subjects to be mastered, and by his infirmity of purpose, rather than by any lack of natural parts, or by idleness or by defect of judgment; vices to which he was in no way addicted. But I, being firmly set upon the object of my wishes, for the reasons given above, and because I perceived that my father had achieved only moderate success--though he had encountered but few hindrances--remained unconvinced by any of his exhortations."[27]

FOOTNOTES:

[1] Bayle is unwilling to admit Cardan's illegitimate birth. In _De Consolatione_, Opera, tom. i. p. 619 (Lyons, 1663), Cardan writes in reference to the action of the Milanese College of Physicians: "Medicorum collegium, suspitione oborta, qud (tam male a patre tractatus) spurius essem, repellebat." Bayle apparently had not read the _De Consolatione_, as he quotes the sentence as the work of a modern writer, and affirms that the word "suspitio" would not have been used had the fact been notorious.

But in the _Dialogus de Morte_, Opera, tom. i. p. 676, Cardan declares that his father openly spoke of him as a b.a.s.t.a.r.d.
