Cardan

Definition and stakes

W. G. Waters,  Jerome Cardan: A Biographical Study

“ When he made a beginning of the De Utilitate Cardan was at the zenith of his fortunes. He had lately returned from his journey to Scotland, having made a triumphant progress through the cities of Western Europe. Thus, with his mind well stored with experience of divers lands, his wits sharpened by intercourse with the élite of the learned world, and his hand nerved by the magnetic stimulant of success, he sat down to write as the philosopher and man of the world, rather than as the man of science. He was, in spite of his prosperity, inclined to deal with the more sombre side of life. ”

W. G. Waters,  Jerome Cardan: A Biographical Study

“ The record of Cardan's life for the next two years is a meagre one. His rest was constantly disturbed either by the machinations of his foes or by the dread thereof, the evil last-named being probably the more noxious of the two. As long ago as 1557 he had begun the treatise De Utilitate ex Adversis Capienda, a work giving evidence [Pg 185] of careful construction, and one which, as a literary performance, takes the first rank. ”

Portrait of Pierre Duhem Pierre Duhem,  The Origins of Statics — CHAPTER III: JÉRÔME CARDAN…

“ In 1551, Cardan published his twenty-one books On Subtlety (7) ; a second Latin edition (8) of this work, more complete than the the first, appeared as early as 1554 and, in 1556, was translated into French by Richard le Blanc (9) ; the French or Latin editions of this work succeeded themselves, numerously, during the second half of the XVIth century (10) . To this writing, Cardan joined later his Opus novum de proportionibus (11) . All the Mechanics contained in these two works carry, still recognizable, the mark of Leonardo. ”
