Madame de Frontignac was one of those women whose beauty is so striking and imposing, that they seem to kindle up, even in the most prosaic apartment, an atmosphere of enchantment. All the pomp and splendor of high life, the wit, the refinements, the nameless graces and luxuries of courts, seemed to breathe in invisible airs around her, and she made a Faubourg St. Germain of the darkest room into which she entered. Mary thought, when she came in, that she had never seen anything so splendid. She was dressed in a black velvet riding-habit, buttoned to the throat with coral; her riding-hat drooped with its long plumes so as to cast a shadow over her animated face, out of which her dark eyes shone like jewels, and her pomegranate cheeks glowed with the rich shaded radiance of one of Rembrandt's pictures. Something quaint and foreign, something poetic and strange, marked each turn of her figure, each article of her dress, down to the sculptured hand on which glittered singular and costly rings,--and the riding-glove, embroidered with seed-pearls, that fell carelessly beside her on the floor. In Antwerp one sees a picture in which Rubens, who felt more than any other artist the glory of the physical life, has embodied his conception of the Madonna, in opposition to the faded, cold ideals of the Middle Ages, from which he revolted with such a bound. _His_ Mary is a superb Oriental sultana, with lustrous dark eyes, redundant form, jewelled turban, standing leaning on the balustrade of a princely terrace, and bearing on her hand, _not_ the silver dove, but a gorgeous paroquet. The two styles, in this instance, were both in the same room; and as Burr sat looking from one to the other, he felt, for a moment, as one would who should put a sketch of Overbeck's beside a splendid painting of Titian's. For a few moments, everything in the room seemed faded and cold, in contrast with the tropical atmosphere of this regal beauty. Burr watched Mary with a keen eye, to see if she were dazzled and overawed. He saw nothing but the most innocent surprise and delight. All the slumbering poetry within her seemed to awaken at the presence of her beautiful neighbor,--as when one, for the first time, stands before the great revelations of Art. Mary's cheek glowed, her eyes seemed to grow deep with the enthusiasm of admiration, and, after a few moments, it seemed as if her delicate face and figure reflected the glowing loveliness of her visitor, just as the virgin snows of the Alps become incarnadine as they stand opposite the glorious radiance of a sunset sky.
