After giving this account of his person, Cardan writes down a catalogue of the various diseases which vexed him from time to time, a chapter of autobiography which looks like a transcript from a dictionary of Nosology. More interesting is the sketch which he makes of his mental state during these early years. Boys brought up in company of their elders often show a tendency to introspection, and fall into a dreamy whimsical mood, and his case is a striking example. "By the command of my father I used to lie abed until nine o'clock,[31] and, if perchance I lay awake any time before the wonted hour of rising, it was my habit to spend the same by conjuring up to sight all sorts of pleasant visions, nor can I remember that I ever summoned these in vain. I used to behold figures of divers kinds like airy bodies. Meseemed they were made up of tiny rings, like those in coats of chain-armour, though at this time I had seen nought of the kind. They would rise at the bottom of the bed, from the right-hand corner; and, moving in a semi-circle, would pass slowly on and disappear in the left. Moreover I beheld the shapes of castles and houses, of horses and riders, of plants, trees, musical instruments, theatres, dresses of men of all sorts, and flute-players who seemed to be playing upon their instruments, but neither voice nor sound was heard therefrom. And besides these things I beheld soldiers, and crowds of men, and fields, and certain bodily forms, which seem hateful to me even now: groves and forests, and divers other things which I now forget. In all this I took no small delight, and with straining eyes I would gaze upon these marvels; wherefore my Aunt Margaret asked me more than once whether I saw anything. I, though I was then only a child, deliberated over this question of hers before I replied, saying to myself: 'If I tell her the facts she will be wroth at the thing—whatever it may be—which is the cause of these phantasms, and will deprive me of this delight.' And then I seemed to see flowers of all kinds, and four-footed beasts, and birds; but all these, though they were fashioned most beautifully, were lacking in colour, for they were things of air. Therefore I, who neither as a boy nor as an old man ever learned to lie, stood silent for some time. Then my aunt said—'Boy, what makes you stare thus and stand silent?' I know not what answer I made, but I think I said nothing at all. In my dreams I frequently saw what seemed to be a cock, which I feared might speak to me in a human voice. This in sooth came to pass later on, and the words it spake were threatening ones, but I cannot now recall what I may have heard on these occasions."[32]
With a brain capable of such remarkable exercises as the above-written vision, living his life in an atmosphere of books, and with all games and relaxations dear to boys of his age denied to him, it was no marvel that Jerome should make an early literary essay on his own account. The death of a young kinsman, Niccolo Cardano,[33] suggested to him a theme which he elaborated in a tract called De immortalitate paranda, a work which perished unlamented by its author, and a little later he wrote a treatise on the calculation of the distances between the various heavenly bodies.[34] But he put his mathematical skill to other and more sinister uses than this; for, having gained practical experience at the gaming-tables, he combined this experience with his knowledge of the properties of numbers, and wrote a tract on games of chance. Afterwards he amplified this into his book, Liber de Ludo Aleæ.
With this equipment and discipline Jerome went to Pavia in 1520. He found lodging in the house of Giovanni Ambrogio Targio, and until the end of his twenty-first year he spent all his time between Pavia and Milan. By this date he had made sufficiently good use of his time to let the world see of what metal he was formed, for in the year following he had advanced far enough in learning to dispute in public, to teach Euclid in the Gymnasium, and to take occasional classes in Dialectics and Elementary Philosophy. At the end of his twenty-second year the country was convulsed by the wars between the Spaniards and the French under Lautrec, which ended in the expulsion of the last-named and the establishment of the Imperial power in Milan. Another result of the war, more germane to this history, was the closing of the University of Pavia through lack of funds. In consequence of this calamity Jerome remained some time in Milan, and during these months he worked hard at mathematics; but he was not destined to return to Pavia as a student. The schools there remained some long time in confusion, so in 1524 he went with his father's consent to Padua. In the autumn of that same year he was summoned back to Milan to find Fazio in the grip of his dying illness. "Whereupon he, careful of my weal rather than his own, bade me return to Padua at once, being well pleased to hear that I had taken at the Venetian College the Baccalaureat of Arts.[35] After my return to Padua, letters were brought to me which told me that he had died on the ninth day after he had refused nourishment. He died on the twenty-eighth of August, having last eaten on Sunday the twentieth of the month. Towards the close of my twenty-fourth year I was chosen Rector of the Academy at Padua,[36] and at the end of the next was made Doctor of Medicine. For the first-named office I came out the victor by one vote, the suffrages having to be cast a second time; and for the Doctorate of Medicine my name had already twice come forth from the ballot with forty-seven votes cast against me (a circumstance which forbade another voting after the third), when, at the third trial, I came out the winner, with only nine votes against me (previously only this same number had been cast for me), and with forty-eight in my favour.
"Though I know well enough that affairs like these must needs be of small account, I have set them down in the order in which they came to pass for no other reason than that I give pleasure to myself who write these words by so doing: and I do not write for the gratification of others. At the same time those people who read what I write—if indeed any one should ever be so minded—may learn hereby that the beginnings and the outcomes of great events may well be found difficult to trace, because in sooth it is the way of such things to come to the notice of anybody rather than of those who would rightly observe them."[37]
Padua cannot claim for its University an antiquity as high as that which may be conceded to Pavia, but in spite of its more recent origin, there is no little obscurity surrounding its rise. The one fact which may be put down as certain is that it sprang originally from the University of Bologna. Early in the thirteenth century violent discords arose between the citizens of Bologna and the students, and there is a tradition that the general school of teaching was transferred to Padua in 1222. What happened was probably a large migration of students, part of whom remained behind when peace between town and gown in Bologna was restored. The orthodox origin of the University is a charter granted by Frederic II. in 1238. Frederic at this time was certainly trying to injure Bologna, actuated by a desire to help on his own University at Naples, and to crush Bologna as a member of the Lombard League.[38] Padua, however, was also a member of this league, so his benevolent action towards it is difficult to understand. In 1228 the students had quarrelled with the Paduan citizens, and there was a movement to migrate to Vercelli; but, whether this really took place or not, the Paduan school did not suffer: its ruin and extinction was deferred till the despotism of the Ezzelini. In 1260 it was again revived by a second migration from Bologna, and this movement was increased on account of the interdict laid by the Pope upon Bologna in 1306 after the expulsion of the Papal Legate by the citizens.
In the early days Medicine and Arts were entirely subordinate to the schools of canon and civil law; but by the end of the fourteenth century these first-named Faculties had obtained a certain degree of independence, and were allowed an equal share in appointing the Rector.[39] The first College was founded in 1363, and after 1500 the number rapidly increased. The dominion of the Dukes of Carrara after 1322 was favourable to the growth of the University, which,
