So extensive was his acquaintance with life and manners, that in an Italian comedy composed by himself, and exhibited before the court of Mantua, he is said to have personated fifteen different characters; in all which he might succeed without great difficulty, since he had such power of retention, that once hearing an oration of an hour, he would repeat it exactly, and in the recital follow the speaker through all his variety of tone and gesticulation. Nor was his skill in arms less than in learning, or his courage inferior to his skill: there was a prize- fighter at Mantua, who travelling about the world, according to the barbarous custom of that age, as a general challenger, had defeated the most celebrated masters in many parts of Europe; and in Mantua, where he then resided, had killed three that appeared against him. The duke repented that he had granted him his protection; when Crichton, looking on his sanguinary success with indignation, offered to stake fifteen hundred pistoles, and mount the stage against him. The duke with some reluctance consented, and on the day fixed the combatants appeared: their weapon seems to have been single rapier, which was then newly introduced in Italy. The prize-fighter advanced with great violence and fierceness, and Crichton contended himself calmly to ward his passes, and suffered him to exhaust his vigour by his own fury. Crichton then became the assailant; and pressed upon him with such force and agility, that he thrust him thrice through the body, and saw him expire: he then divided the prize he had won among the widows whose husbands had been killed. The death of this wonderful man I should be willing to conceal, did I not know that every reader will inquire curiously after that fatal hour, which is common to all human beings, however distinguished from each other by nature or by fortune. The duke of Mantua, having received so many proofs of his various merit, made him tutor to his son Vicentio di Gonzaga, a prince of loose manners and turbulent disposition. On this occasion it was, that he composed the comedy in which he exhibited so many different characters with exact propriety. But his honour was of short continuance; for as he was one night in the time of Carnival rambling about the streets, with his guitar in his hand, he was attacked by six men masked. Neither his courage nor skill in his exigence deserted him: he opposed them with such activity and spirit, that he soon dispersed them, and disarmed their leader, who throwing off his mask, discovered himself to be the prince his pupil. Crichton, falling on his knees, took his own sword by the point, and presented it to the prince; who immediately seized it, and instigated, as some say, by jealousy, according to others, only by drunken fury and brutal resentment, thrust him through the heart.
