After the tender Isabella came the heroic loveliness of Euphrasia, with Bensley for Evander, her success in which shook the laurels on the brows of Mrs. Yates, and the widow of Spranger Barry. Having given new life to Murphy's dull lines in a play which, nevertheless, does not lack incident, she appeared as Jane Shore to Smith's Hastings, and with such effect that not only were sobs and shrieks heard from the ladies, but men wept like children, and "fainting fits," says Campbell, "were long and frequent in the house."

To the Lothario of Palmer and Horatio of Bensley, Mrs. Siddons next played Calista, in another of Rowe's tragedies, the "Fair Penitent,"—that impersonation of pride, anguish, anger, shame, and sorrow, and with undiminished success. But in Belvidera (to the Jaffier of Brereton, and Pierre of Bensley) she seems to have surpassed all she had hitherto accomplished over the minds and feelings of the audience, whom she fairly electrified. Her Belvidera, with its honest, passionate, overwhelming love and truth, was well contrasted with her scorn and magnificence of demeanour in Zara. The whole season was one of triumph,—the only dark spot in which was the failure of Hull's "Fatal Interview," in which she played Mrs. Montague, but with so little effect, where, indeed, no opportunity was given her of creating any, as to injure for a moment a prestige which grew all bright again by her performance of Calista.

It is singular that she liked her part in Hull's play—"a new tragedy, in prose," she writes; "a most affecting play, in which I have a part that I like very much;" but she adds, from her house, 149 Strand, "the 'Fatal Interview' has been played three times, and is quite done with. It was the dullest of all representations."

Of Mrs. Crawford (Barry) the new actress entertained some small fears, which are not too generously expressed in a letter to Dr. Whalley. "I should suppose she has a very good fortune, and I should be vastly obliged if she would go and live very comfortably upon it ... let her retire as soon as she pleases!" At this time, when her second benefit brought her nearly £700, her ideas of supreme bliss were limited to a cottage in the country, and a capital of £10,000.

Her success brought her many an enemy, the most virulent and unmanly of whom was an anonymous paragraph-writer in the newspapers, who slandered her daily, and for a brief moment excited against her the ill will of the public. "He loaded her with opprobrium," says an anonymous contemporary, "for not alleviating the distresses of her (alleged) sister,"[58] Mrs. Curtis, a vicious woman, who, according to the quaintly circumstantial writer, "would not conform to modesty, though offered a genteel annuity on that condition." Mrs. Curtis read lectures at Dr. Graham's Temple of Health, and the wayward woman attempted to poison herself in Westminster Abbey. The enemies of Mrs. Siddons somehow connected her with both circumstances, as they subsequently did with that of old Roger Kemble applying, humbly, for relief from some charitable fund, in the hands of a banker. Probably the ex-hairdresser was proud, and may have preferred to apply for aid to a fund which he had helped to sustain than to take it from his children. The story is detailed by Genest, who seems inclined to place some faith in it!

Ireland eagerly invited the new actress, and she crossed from Holyhead to Dublin in a storm, which she looked on or endured with a "pleasing terror." Landing in the middle of a wet night in June, no tavern even would then receive a woman and a stranger, and it was with difficulty that her companion Brereton, a promising Irish actor, whom she had instructed in Jaffier, procured accommodation for her, in the house where he himself lodged. She played with equal success at Cork as at Dublin, particularly in Zara. From the former place she writes to Dr. Whalley:—"I have sat to a young man in this place who has made a small full length of me in Isabella, upon the first entrance of Biron ... he has succeeded to admiration. I think it more like me than any I have ever yet seen." Who was this unnamed artist? Where is this young Isabella?

Mrs. Siddons returned to England, richer by £1000 by her Irish summer excursion, and with an antipathy against the people, which could only be momentary in the daughter of a lady born in Clonmel. Her season of 1783-84 at Drury was doubly marked: she played two Shakspearian characters—Isabella, in "Measure for Measure," to Smith's Duke; and Constance, in "King John," to the King of her own brother, John Kemble. The first was a greater success than the second; but Constance became ultimately one of the most perfect of her portraitures.

To see her Isabella, in the "Fatal Marriage," the whole royal family went in quaint state. To her brother's Beverley, she played the wife, in a way which affected the actors as much as it did the audience. In the Countess of Salisbury, one of Mrs. Crawford's great parts, and Sigismunda, she comparatively failed; but she achieved a double triumph in Lady Randolph. It will be remembered how she had desired the retreat of Mrs. Crawford. The old actress had been famous for her performance of Lady Randolph, which she played on her reappearance at Covent Garden in November 1783. Her oldest admirers (some critics excepted) confessed that her powers were shaken. A month afterwards Mrs. Siddons played the same character, for her benefit, to the Young Norval of Brereton, when the old actress succumbed at once, by comparison; but it is doubtful if Mrs. Siddons excelled her, if the comparison be confined to the period when each actress was in youth, strength, and beauty. "Mrs. Siddons," says Campbell, "omitted Mrs. Crawford's scream, in the far-famed question, 'Was he alive?'" In 1801, the year when Mrs. Crawford was laid by the side of her husband, Barry, in Westminster Abbey, Mr. Simons, says Genest, "in a small party at Bath, went through the scene between Old Norval and Lady Randolph,—his imitation of Mrs. Crawford was most perfect, particularly in 'Was he alive?' Mrs. Piozzi, who was present, said to him,—'do not do that before Mrs. Siddons; she would not be pleased.'"

The King shed tears, however, at her acting; and the Queen, turning her back to the stage, styled it in her broken English "too disagreeable;" but she appointed Mrs. Siddons preceptress in English reading to the Princesses, without any emolument, and kept her standing in stiff and stately dress, including a hoop, which Mrs. Siddons especially detested, till she was ready to faint! The King, too, praised her correct emphasis, mimicked the false ones of other actors, and set her above Garrick on one point, that of repose, whereas, he said, "Garrick could never stand still. He was a great fidget."

The Countesses entrapped her into parties where crowds of well-bred people stood on the chairs to stare at her. One invalid Scotch lady, whose doctor had forbidden her going to the theatre, went unintroduced to Mrs. Siddons's residence, then in Gower Street, and calmly sat down, gazed at her for some minutes, and then walked silently away. Sir Joshua Reynolds painted his name on the hem of her garment, in his portrait of her as the Tragic Muse, and Dr. Johnson kissed her hand, and called her "My dear Madam," on his own staircase. Statesmen were glad, when she played, to sit among the fiddlers; and the fine gentlemen of the day, including him of "Wales," visited her in her dressing-room, after the play, "to make their bows." And then she rode home in "her own carriage!"
