It happened one day that Salvator Rosa, in his youth, on his way to mass, brought with him by mistake, his bundle of burned sticks, with which he used to draw, instead of his mother's brazen clasped missal; and in passing along the magnificent cloisters of the great church of the Certosa at Naples, sacred alike to religion and the arts, he applied them between the interstices of its Doric columns to the only unoccupied space on the pictured walls. History has not detailed what was the subject which occupied his attention on this occasion, but he was working away with all the ardor which his enthusiastic genius inspired, when unfortunately the Prior, issuing with his train from the choir, caught the hapless painter in the very act of scrawling on those sacred walls which required all the influence of the greatest masters to get leave to ornament. The sacrilegious temerity of the boy artist, called for instant and exemplary punishment. Unluckily too, for the little offender, this happened in Lent, the season in which the rules of the rigid Chartreuse oblige the prior and procurator to flagellate all the frati, or lay brothers of the convent. They were, therefore, armed for their wonted pious discipline, when the miserable Salvatoriello fell in their way; whether he was honored by the consecrated hand of the prior, or writhed under the scourge of the procurator, does not appear; but that he was chastised with great severity more than proportioned to his crime, is attested by one of the most scrupulous of his biographers, Pascoli, who, though he dwells lightly on the fact, as he does on others of more importance, confesses that he suffered severely from the monks' flagellation.
