Jerome Cardan by William George Waters (important books to read .txt) 📕

"To be content that times to come should only know there was such a man, not caring whether they knew more of him, was a frigid ambition in Cardan."--SIR THOMAS BROWNE.


PREFACE

No attempt is made in the following pages to submit to historical treatment the vast and varied mass 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 circumstances 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 homogeneous treatment than is possible in a chronicle of the passing 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 quantity 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 analyses of some of Cardan's more popular works which Professor Morley gives are admirable in their way, but the space 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 passages translated from the _De Vita Propria_ and the _De Utilitate ex Adversis capienda_, passages 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 gratitude the valuable assistance 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 illustrious 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 bastardy.[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 principal church at Gallarate.[2] He asserts 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., Godfrey 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 passage 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 space 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 circumstances 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 circumstances, 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 godfather, 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 chastisement he always fell sick, and
