On October 4 Rienzi was played—played to crowded houses, with audiences so rapt that a pin might have been heard had one dropped in the house. The author, fearful of failure, dare not witness the first production, but remained near at hand, praying for success from her inmost soul, “for on it hangs the comfort of those far dearer to me than myself.” It was Haydon who was the first to bring her the news of success, and it was a message the bearer of which she never forgot.

On October 20 she wrote informing Sir William Elford that “the triumph has been most complete and decisive—the houses crowded—and the attention such as has not been since Mrs. Siddons. How long the run may continue I cannot say, for London is absolutely empty; but even if the play were to stop to-night, I should be extremely thankful—more thankful than I have words to tell; the impression has been so deep and so general. You should have been in London, or seen the newspapers as a whole, to judge of the exceedingly strong sensation that has been produced.”

“The reception of this tragedy,” wrote George Daniel, the famous critic and Editor of Cumberland’s British Theatre, “is a proof that, though the public have been wont to feed on garbage, they have no disinclination to wholesome food.... If in the character of Rienzi, Miss Mitford has shown that she can write with masculine energy, let Claudia bear witness that her wonted dominion over the heart is still in full force; that, with the power of agitating the soul by the fierce conflict of contending passions, a fine sensibility, a true pathos, a bewitching tenderness, are still her own, to relieve and illumine the dark shadows that veil the mysterious grandeur of the tragic muse.

“The sentiments are just and noble; the language is vigorous, picturesque and poetical.

“It was to be expected that the actor who plays Macbeth and Hamlet with such skill and effect as Mr. Young should be highly successful in Rienzi. His performance was a fine specimen of the Kemble school—chaste, vigorous and grand. Miss Phillips proved herself fully equal to sustain the character of the gentle Claudia. Her excellence lies in the expression of tenderness.”

Congratulations poured in upon the author from all quarters, and these, with countless invitations to festivities in her honour, nearly turned her head. Fulfilling a promise made at the Hofland’s house to Mrs. Hall, she went to dinner one evening during the run of Rienzi, and was, unconsciously, the cause of much merriment, fortunately suppressed. Mrs. Hall describes her as not appearing to advantage that evening; “her manner was constrained, and even haughty. She got up tragedy looks, which did not harmonize with her naturally playful expression. She seated herself in a high chair, and was indignant at the offer of a footstool, though her feet barely touched the ground; she received those who wished to be introduced to her en reine; but such was her popularity just then, that all were gratified. She was most unbecomingly dressed in a striped satin something, neither high nor low, with very short sleeves, for her arms were white and finely formed; she wore a large yellow turban, which added considerably to the size of her head. She had evidently bought the hideous thing en route, and put it on, in the carriage, as she drove to our house, for pinned at the back was a somewhat large card, on which were written in large letters, ‘VERY CHASTE—ONLY 5s. 3d.’ I had observed several of our party passing behind the chair, whispering and tittering, and soon ascertained the cause. Under pretence of settling her turban, I removed the obnoxious notice; and, of course, she never knew that so many wags had been merry at her cost.”

All very amusing; and yet, a picture which cannot fail to evoke our sympathy for the little woman so anxious to enjoy to the full her wonderful hour of success.

The play ran for fifty nights and enjoyed a truly remarkable sale in book form. In view of the popularity of Rienzi and, possibly, because she feared it might affect the run in some way, Miss Mitford now begged Kemble to postpone the production of Inez de Castro until some future date, to which he, of course, agreed.

Meanwhile, and in the November of the same year—that is, while Rienzi was still running—she made preparations towards the writing of a new play, founded on a German story, and to be called Otto of Wittelsbach.

Upon her return to Three Mile Cross she was again inundated with congratulations, both personal and written, and this, of course, proved a serious delay to her work, and, incidentally, led to a temporary break in her correspondence with her old friend, Sir William Elford. Conscience-stricken, she sent him a pretty letter—an amusing blend of contrition and excuse—on her birthday.
