Of Crichton’s exploits in Paris, the following account has been given by Mackenzie, and translated by Pennant, from the testimony of an author whom they consider as an eye-witness.

“There came to the college of Navarre, a young man of twenty years of age, who was perfectly well seen in all the sciences, as the most learned masters of the University acknowledged. In vocal and instrumental music, none could excel him; in painting and drawing in colours, none could equal him. In military feats he was most expert; and could play with the sword so dexterously with both his hands, that no man could fight him. When he saw his enemy or antagonist, he would throw himself upon him at one jump of twenty or twenty-four feet distance. He was master of arts, and disputed with us in the schools of the college, on medicine, the civil and canon law, and theology. And, although we were above fifty in number, besides about three thousand who were present, so pointedly and learnedly he answered to all the questions which were proposed to him, that none but they who were present can believe it. He spoke Latin, Greek, and Hebrew, and other languages, most politely. He was likewise a most excellent horseman; and, truly, if a man should live a hundred years, without eating, drinking, or sleeping, he could not attain to this man’s knowledge, which struck us with a panic fear, for he knew more than human nature can well bear. He overcame four of the doctors of the church; for in learning none could contest with him; and he was thought to be Antichrist.”

Having thus obtained in Paris the victory for which he contended, Crichton next repaired to Rome, where he affixed a placard upon all the eminent places of the city, in the following terms:—“Nos Jacobus Crictonus Scotus, cuicunque Rei propositæ ex improviso respondebimus.” In a city which abounded with scholastic learning and wit, this challenge, bearing all the marks of presumption, soon became the subject of a pasquinade. Rome, it has been said, was at this time much infested with mountebanks, jugglers, and other empirics; and those who felt indignant at the placard of Crichton, endeavoured to ridicule him, by classifying him with the quacks. Designating him by the neuter gender, their pasquinade was to the following effect:—“And he that will see it, let him repair to the sign of the Falcon, and it shall be shewn.” Boccalini, who was then at Rome, says, that the appearance of this paper had such an effect upon him, that, with indignant feelings, he almost immediately left the city, where he had been so grossly insulted, in being compared to the impostors who could only amuse the vulgar. Mackenzie, however, asserts, that instead of being discouraged, he appeared at the time and place appointed; and, in the presence of the Pope, many Cardinals, Bishops, and Doctors of Divinity, and Professors of all the Sciences, displayed such wonderful proofs of his universal knowledge, that he excited a degree of astonishment equal to that which had marked his career in Paris.

From Rome, Crichton proceeded to Venice, in which place he appears to have been reduced to much distress; but whether this arose from any mental depression, from bodily indisposition, or from embarrassment of circumstances, is not clearly expressed. The reality of his distress he has stated in a poem, the principal design of which was, to obtain a favourable reception in the city; and more particularly so, with Aldus Manutius, a celebrated critic. On presenting his verses, Manutius was struck with an agreeable surprise, at the comprehensiveness of thought, the display of intellect, and the brilliancy of genius, which they exhibited. And, upon conversing with the author, he was so filled with admiration on finding him intimately acquainted with almost every subject, that he introduced him to the acquaintance of the principal men of learning and note in Venice.

Thus recommended, he contracted an intimate friendship with Manutius, Massa, Speronius, Donatus, and various others, to whom he presented several poems, in commendation of the university and city. Three of these odes are still preserved. After some time he was introduced to the Doge and Senate, in whose presence he delivered a speech, fraught with so much beauty and eloquence, and accompanied with such gracefulness of person and manners, that he received the thanks of that illustrious body; and nothing was talked about for some time, through the city, but this rara avis in terris,—this prodigy in nature. In this city, also, he held various disputations, on theology, philosophy, and mathematics, with the most eminent professors, and before vast concourses of people. The talents which he displayed on these occasions, gave such publicity to his reputation, that multitudes repaired to Venice from distant parts, that they might have an opportunity of seeing and hearing a man, whose abilities were considered as almost super-human.

Adorned with all the laurels of literature which Venice could bestow, Crichton next removed to Padua, the university of which was, at this time, in high repute. On the day after his arrival, there was a general meeting of all the learned men which this place could boast; but on what occasion they were convened, we are not informed. The fame of Crichton, however, gained him an admission into this learned assembly, whom he immediately addressed in an extemporary poem, in praise of the city, of the university, and of the company that had honoured him with their presence. Having finished this introductory address to the admiration of all present, he disputed during six hours with the most celebrated professors, on various subjects of learning. It was during this debate, that he exposed the errors of Aristotle and his commentators, with so much solidity, acuteness, and modesty, that the admirers of this philosopher were astonished at his acquirements, and even filled with profound admiration. Before they separated, he delivered, extempore, an oration in praise of Ignorance, which he conducted with so much ingenuity, managed with such exquisite skill, and expressed with so much elegance, that his hearers were almost overwhelmed with amazement. This display of his learning and talents took place on the 14th of March, 1581, in the house of Jacobus Aloysius Cornelius.

As several persons of considerable rank, who were absent on the above memorable day, expressed their regret on this occasion, Crichton appointed another, to meet any opponents who might be disposed to encounter him; merely to comply with their earnest solicitations, and to afford them gratification. Whether this meeting ever took place, seems rather uncertain. Manutius asserts, that some circumstances occurred which prevented it; but Imperialis observes, from information communicated by his father, who was present on the occasion, that Crichton was formidably opposed by Archangelus Mercenarius, a famous philosopher, but that the young foreigner was finally victorious, and obtained the plaudits of the auditors, and the approbation even of his antagonist.

But this tide of popular applause was not without its corresponding eddy. Mortified at being foiled by this youthful stranger, many, even among the learned, envied both his fame and merit, and did not hesitate to resort to artifices, which, they imagined, would lessen his reputation. Crichton was not ignorant of these contrivances; and, conscious of his own transcendent abilities and attainments, he resolved to give all who were inclined to detract from his merit, a convincing proof of his decided superiority. He therefore caused a paper to be fixed on the gates of St. John’s and St. Paul’s churches, in which he offered to prove, before the University, that both Aristotle and his followers had fallen into almost innumerable errors; and that the latter had failed in explaining the philosophy of their master, and had erred in their application of his principles to theological subjects. He engaged, likewise, to refute the theories of several mathematical professors; offered to dispute with any one on all the sciences; and promised to answer whatever might be proposed to him, or objected against what he should advance. All this he engaged to do, either in the common logical way, or by numbers and mathematical figures; or, in case his antagonists should prefer it, in no less than one hundred sorts of verses.

The men who had been secretly contriving how to undermine his reputation, beheld this challenge with strange emotions. From the presumption which it displayed, they flattered themselves with an easy conquest; but from the talents which Crichton had on all former occasions manifested, and his being constantly victorious, they became intimidated, and hesitated to accept the summons they had provoked. They had, however, proceeded too far to retreat; and therefore nothing remained but for them to collect their forces, and meet him, agreeably to his proposal. Manutius informs us, that the meeting took place at the time appointed; that the disputations continued for three days; and that Crichton, during the whole contest, supported his credit, and maintained his propositions with so much spirit and energy, and apparently with so little fatigue, that he obtained, from an unusual concourse of people, such acclamations and praises as were scarcely ever before received by man.

Nor were the bodily powers, activity, and skill, of this astonishing man less conspicuous, than those energies by which his mind was distinguished. Of these, also, he has given some surprising proofs in his various exploits.
