The duke, as the best reply he could make to this noble petitioner for her enemy’s life, sending for Claudio from his prison-house, where he lay doubtful of his destiny, presented to her this lamented brother living; and he said to Isabel, “Give me your hand, Isabel; for your lovely sake I pardon Claudio. Say you will be mine, and he shall be my brother too.” By this time lord Angelo perceived he was safe; and the duke observing his eye to brighten up a little, said, “Well, Angelo, look that you love your wife; her worth has obtained your pardon: joy to you, Mariana! Love her, Angelo! I have confessed her, and know her virtue.” Angelo remembered, when drest in a little brief authority, how hard his heart had been, and felt how sweet is mercy.
The duke commanded Claudio to marry Juliet, and offered himself again to the acceptance of Isabel, whose virtuous and noble conduct had won her prince’s heart. Isabel, not having taken the veil, was free to marry; and the friendly offices, while hid under the disguise of a humble friar, which the noble duke had done for her, made her with grateful joy accept the honour he offered her; and when she became duchess of Vienna, the excellent example of the virtuous Isabel worked such a complete reformation among the young ladies of that city, that from that time none ever fell into the transgression of Juliet, the repentant wife of the reformed Claudio. And the mercy-loving duke long reigned with his beloved Isabel, the happiest of husbands and of princes.
