The Enigmatic Cardano: Mathematician, Doctor, Gambler, and More

Cardano, whose full appellation is Girolamo Cardano, distinguished himself as an eminent mathematician, physician, astrologer, and gamester amidst the milieu of the Italian Renaissance. His tenure, spanning from 1501 to 1576, marked him as one of the preeminent savants of the European Renaissance epoch. Across varied domains such as mathematics, medicine, astronomy, and philosophy, Cardano traversed, establishing himself as a luminary within the annals of scientific history.

Cardano drew his inaugural breath in Pavia, nestled south of Milan, on the vernal equinox of September 23, 1501. He emerged as the progeny of an illicit liaison between a magistrate and a widow. His mother, then in the autumn of her years, cohabited with her septuagenarian sire alongside her trio of offspring. Laboring for three arduous days preceding his advent, she eventually formalized her union with the scion’s progenitor.

In his formative years, Cardano resided with his wet nurse in the hamlet of Moirago, beyond the confines of Milan, for a quadrennium ere his return to his familial hearth. Endowed with a familial predisposition towards longevity, Cardano hailed from stock wherein both grandsire and sire attained octogenarian and sexagenarian milestones, respectively, each endowed with mathematical acumen. Under paternal auspices, Cardano commenced his erudition, delving into the realms of classical literature, mathematics, and astrology. Embarking on his academic sojourn at the age of nineteen, he matriculated at the University of Pavia, alma mater to the likes of Columbus, to pursue medical studies. Subsequently, he transposed his academic endeavors to the University of Padua, where Galileo once imparted wisdom. At the tender age of twenty-five, he clinched his doctorate.

As a mathematician, Cardano’s oeuvre predominantly ornamented the domain of algebra. His magnum opus, “Dafa,” stands as the cornerstone of algebraic discourse. Within its folios, Cardano proffered a panoptic solution to algebraic equations, amalgamating equation elucidation with geometric configurations, thus bequeathing an indelible cornerstone for subsequent algebraic inquiry. Moreover, he scrutinized the interplay betwixt roots and coefficients of equations, advocating for the generalized manifestation of quadratic equations, thereby furnishing seminal inspiration to posterity’s mathematicians.

Beyond the purview of mathematics, Cardano etched illustrious contributions within the precincts of medicine. Pioneeringly, he documented the clinical manifestations of typhus. His treatises on typhus engendered indispensable benchmarks for ensuing medical inquiry. As delineated in Chapter 40 of his autobiography, “Examples of Successful Medical Practice,” Cardano salvaged over a hundred patients, erstwhile deemed incurable by their peers, from afflictions ranging from pulmonary maladies to mental derangement. Furthermore, he authored “The Dying Man,” a compendium expounding upon maladies and their remedies, garnering widespread citation and exerting a profound influence upon medical evolution.

Despite his seminal forays into mathematics and medicine, Cardano’s renown is perhaps most pronounced in his capacities as an astrologer and a gaming enthusiast. Proficient in astrology, he prognosticated destinies for sundry clientele, while his tome “The Four Books of Astrology” wielded a palpable sway upon the trajectory of astrological doctrine.

Set against the tempestuous backdrop of sixteenth-century Italy, Cardano weathered a milieu rife with calamity. His sojourn in Rome coincided with an era marked by dilapidated thoroughfares. The vicissitudes of political vicissitudes and the seismic convulsions wrought by the Reformation furnished the tumultuous tableau against which Cardano’s narrative unfolded. Personally beset by privation, ignominy, and infirmity during the nascent stage of his existence, Cardano’s matrimonial union was fraught with discontent. His progeny, siring two sons and a daughter, was marred by tragedy, culminating in fratricide and filicide, leaving indelible scars upon his psyche.

In 1574, a mere annum antecedent to his demise, Cardano commenced chronicling his memoirs, “My Life,” in Latin. Sixty-seven years posthumously, in 1643, the inaugural publication of “My Life” ensued in Paris. In the autumnal equinox of 2021, the Chinese iteration of “My Life” shall grace the annals of academia, courtesy of Zhejiang University Press, under the aegis of Professor Wang Xiansheng from the School of Liberal Arts at Shantou University.

Throughout his lifetime, Cardano bequeathed a corpus exceeding two hundred treatises and essays, tallying over seven thousand pages of extant material. Chapter 45 of “My Life” meticulously itemizes his oeuvre, encompassing treatises in mathematics, physics, astronomy, and moral philosophy. His magisterial works, “On the Subtleties of Things” and “On Many Things,” spanning twenty-two and seventeen volumes respectively, epitomize encyclopedic compendia, enshrining insights into mechanics, astronomy, chemistry, biology, cryptography, alchemy, and astrology.

Cardano’s peregrinations, punctuated by adversity, engendered an idiosyncratic persona, oft-castigated as eccentric within the annals of scientific lore. A temperamental and irascible soul, he remained indifferent to pecuniary pursuits, instead espousing an abiding faith in dreams and omens, coupled with an enduring fascination for astrology. Even his demise purportedly served as a validation of his divinatory prowess, shrouding his passing in the pall of alleged self-immolation.

The eminent German philosopher and mathematician Leibniz, in a poignant assessment, opined, “He is a great man with many shortcomings. Without these shortcomings, he would be unparalleled.”
