’What I want you to do is to procure for me its presentation at Covent Garden.  The principal character, Beatrice, is precisely fitted for Miss O’Neil, and it might even seem to have been written for her (God forbid that I should see her play it—­it would tear my nerves to pieces); and in all respects it is fitted only for Covent Garden.  The chief male character I confess I should be very unwilling that any one but Kean should play.  That is impossible, and I must be contented with an inferior actor.’

The play was accordingly sent to Mr. Harris.  He pronounced the subject to be so objectionable that he could not even submit the part to Miss O’Neil for perusal, but expressed his desire that the author would write a tragedy on some other subject, which he would gladly accept.  Shelley printed a small edition at Leghorn, to ensure its correctness; as he was much annoyed by the many mistakes that crept into his text when distance prevented him from correcting the press.

Universal approbation soon stamped “The Cenci” as the best tragedy of modern times.  Writing concerning it, Shelley said:  ’I have been cautious to avoid the introducing faults of youthful composition; diffuseness, a profusion of inapplicable imagery, vagueness, generality, and, as Hamlet says, “words, words".’  There is nothing that is not purely dramatic throughout; and the character of Beatrice, proceeding, from vehement struggle, to horror, to deadly resolution, and lastly to the elevated dignity of calm suffering, joined to passionate tenderness and pathos, is touched with hues so vivid and so beautiful that the poet seems to have read intimately the secrets of the noble heart imaged in the lovely countenance of the unfortunate girl.  The Fifth Act is a masterpiece.  It is the finest thing he ever wrote, and may claim proud comparison not only with any contemporary, but preceding, poet.  The varying feelings of Beatrice are expressed with passionate, heart-reaching eloquence.  Every character has a voice that echoes truth in its tones.  It is curious, to one acquainted with the written story, to mark the success with which the poet has inwoven the real incidents of the tragedy into his scenes, and yet, through the power of poetry, has obliterated all that would otherwise have shown too harsh or too hideous in the picture.  His success was a double triumph; and often after he was earnestly entreated to write again in a style that commanded popular favour, while it was not less instinct with truth and genius.  But the bent of his mind went the other way; and, even when employed on subjects whose interest depended on character and incident, he would start off in another direction, and leave the delineations of human passion, which he could depict in so able a manner, for fantastic creations of his fancy, or the expression of those opinions and sentiments, with regard to human nature and its destiny, a desire to diffuse which was the master passion of his soul.
