Although Mrs. Radcliffe was as far as possible removed from the slavery of superstitious fear, she took an eager interest in the work of composition, and was, for the time, completely absorbed in the conduct of her stories. The pleasures of painting have been worthily celebrated by men, who have been devoted to the art; but these can scarcely be regarded as superior to the enjoyments of a writer of romance, conscious of inventive power. If in the mere perusal of novels we lose our painful sense of the realities of “this unimaginable world,” and delightedly participate in the sorrows, the joys, and the struggles of the persons, how far more intensely must an authoress like Mrs. Radcliffe feel that outgoing of the heart, by which individuality is multiplied, and we seem to pass a hundred lives! She spreads out many threads of sympathy and lives along every line. The passions, the affections, the hopes of her character are essentially hers; born out of her own heart; figured from the tracings of her own brain; and reflecting back again, in shape and form, the images and thoughts, which work indistinctly in the fancies of others. There is a perpetual exercise of that plastic power, which realizes the conceptions of the mind to itself, and gives back to it its own imaginations in “clear dream and solemn vision.” How delightful to trace the dawnings of innocent love, like the coming on of spring; to unveil the daily course of a peaceful life, gliding on like smooth water; to exhibit the passions in their high agitations and contests; to devise generous self-sacrifice in heroic thought; to pour on the wearied and palpitating heart overflowing happiness; to throw the mind forward to advanced age, and through its glass to take a mournful retrospect of departed joy, and pensively understand a mild and timely decay! No exertion of the faculties appears more enviable than that of forming the outline of a great tale, like “The Mysteries of Udolpho;” bringing out into distinctness all the hints and dim pictures, which have long floated in the mind; keeping in view the catastrophe from the first, and the relations to it of the noblest scenes and most complicated adventures; and feeling already, as through all the pulses of the soul, the curiosity, the terror, the pity and the admiration, which will be excited by the perusal in the minds of thousands and thousands of readers.
