All that appears certain is, that Tasso spoke violent and contemptuous words against the duke; that he often spoke ill of him in his letters; that he endeavoured, not with perfect ingenuousness, to exchange his service for that of another prince; that he asserted his madness to have been pretended in the first instance purely to gratify the duke’s whim for thinking it so (which was one of the reasons perhaps why Alfonso, as he complained, would not believe a word be said); and finally, that, whether the madness was or was not so pretended, it unfortunately became a confirmed though milder form of mania, during a long confinement. Alfonso, too proud to forgive the poet’s contempt, continued thus to detain him, partly perhaps because he was not sorry to have a pretext for revenge, partly because he did not know what to do with him, consistently either with his own or the poet’s safety. He had not been generous enough to put Tasso above his wants; he had not address enough to secure his respect; he had not merit enough to overlook his reproaches. If Tasso had been as great a man as he was a poet, Alfonso would not have been reduced to these perplexities. The poet would have known how to settle quietly down on his small court-income, and wait patiently in the midst of his beautiful visions for what fortune had or had not in store for him. But in truth, he, as well as the duke, was weak; they made a bad business of it between them; and Alfonso the Second closed the accounts of the Este family with the Muses, by keeping his panegyrist seven years in a mad-house, to the astonishment of posterity, and the destruction of his own claims to renown.
It does not appear that Tasso was confined in any such dungeon as they now exhibit in Ferrara. The conduct of the Prior of the Hospital is more doubtful. His name was Agostino Mosti; and, strangely enough, he was the person who had raised a monument to Ariosto, of whom he was an enthusiastic admirer. To this predilection has been attributed his alleged cruelty to the stranger from Sorrento, who dared to emulate the fame of his idol;—an extraordinary, though perhaps not incredible, mode of skewing a critic’s regard for poetry. But Tasso, while he laments his severity, wonders at it in a man so well bred and so imbued with literature, and thinks it can only have originated in “orders."[27] Perhaps there were faults of temper on both sides; and Mosti, not liking his office, forgot the allowance to be made for that of a prisoner and sick man. His nephew, Giulio Mosti, became strongly attached to the poet, and was a great comfort to him.
