This woman was the daughter of Sir Charles Sedley, one of the most brilliant and profligate wits of the Restoration. The licentiousness of his writings is not redeemed by much grace or vivacity; but the charms of his conversation were acknowledged even by sober men who had no esteem for his character. To sit near him at the theatre, and to hear his criticisms on a new play, was regarded as a privilege.65 Dryden had done him the honour to make him a principal interlocutor in the Dialogue on Dramatic Poesy. The morals of Sedley were such as, even in that age, gave great scandal. He on one occasion, after a wild revel, exhibited himself without a shred of clothing in the balcony of a tavern near Covent Garden, and harangued the people who were passing in language so indecent and profane that he was driven in by a shower of brickbats, was prosecuted for a misdemeanour, was sentenced to a heavy fine, and was reprimanded by the Court of King's Bench in the most cutting terms.66 His daughter had inherited his abilities and his impudence. Personal charms she had none, with the exception of two brilliant eyes, the lustre of which, to men of delicate taste, seemed fierce and unfeminine.
Her form was lean, her countenance haggard. Charles, though he liked her conversation, laughed at her ugliness, and said that the priests must have recommended her to his brother by way of penance. She well knew that she was not handsome, and jested freely on her own homeliness. Yet, with strange inconsistency, she loved to adorn herself magnificently, and drew on herself much keen ridicule by appearing in the theatre and the ring plastered, painted, clad in Brussels lace, glittering with diamonds, and affecting all the graces of eighteen.67The nature of her influence over James is not easily to be explained. He was no longer young. He was a religious man; at least he was willing to make for his religion exertions and sacrifices from which the great majority of those who are called religious men would shrink. It seems strange that any attractions should have drawn him into a course of life which he must have regarded as highly criminal; and in this case none could understand where the attraction lay. Catharine herself was astonished by the violence of his passion. "It cannot be my beauty," she said; "for he must see that I have none; and it cannot be my wit, for he has not enough to know that I have any."At the moment of the King's accession a sense of the new responsibility which lay on him made his mind for a time peculiarly open to religious impressions. He formed and announced many good resolutions, spoke in public with great severity of the impious and licentious manners of the age, and in private assured his Queen and his confessor that he would see Catharine Sedley no more. He wrote to his mistress intreating her to quit the apartments which she occupied at Whitehall, and to go to a house in Saint James's Square which had been splendidly furnished for her at his expense. He at the same time promised to allow her a large pension from his privy purse. Catharine, clever, strongminded, intrepid, and conscious of her power, refused to stir. In a few months it began to be whispered that the services of Chiffinch were again employed, and that the mistress frequently passed and repassed through that private door through which Father Huddleston had borne the host to the bedside of Charles. The King's Protestant ministers had, it seems, conceived a hope that their master's infatuation for this woman might cure him of the more pernicious infatuation which impelled him to attack their religion. She had all the talents which could qualify her to play on his feelings, to make game of his scruples, to set before him in a strong light the difficulties and dangers into which he was running headlong. Rochester, the champion of the Church, exerted himself to strengthen her influence. Ormond, who is popularly regarded as the personification of all that is pure and highminded in the English Cavalier, encouraged the design. Even Lady Rochester was not ashamed to cooperate, and that in the very worst way. Her office was to direct the jealousy of the injured wife towards a young lady who was perfectly innocent. The whole court took notice of the coldness and rudeness with which the Queen treated the poor girl on whom suspicion had been thrown: but the cause of Her Majesty's ill humour was a mystery. For a time the intrigue went on prosperously and secretly. Catharine often told the King plainly what the Protestant Lords of the Council only dared to hint in the most delicate phrases. His crown, she said, was at stake: the old dotard Arundell and the blustering Tyrconnel would lead him to his ruin. It is possible that her caresses might have done what the united exhortations of the Lords and the Commons, of the House of Austria and the Holy See, had failed to do, but for a strange mishap which changed the whole face of affairs.
James, in a fit of fondness, determined to make his mistress Countess of Dorchester in her own right. Catharine saw all the peril of such a step, and declined the invidious honour. Her lover was obstinate, and himself forced the patent into her hands. She at last accepted it on one condition, which shows her confidence in her own power and in his weakness. She made him give her a solemn promise, not that he would never quit her, but that, if he did so, he would himself announce his resolution to her, and grant her one parting interview.
