Among Margaret's published papers on literature and art is one entitled "A Record of Impressions produced by the Exhibition of Mr. Allston's Pictures in the Summer of 1839." She was moved to write this, she says, partly by the general silence of the press on a matter of so much import in the history of American art, and partly by the desire to analyze her own views, and to ascertain, if possible, the reason why, at the close of the exhibition, she found herself less a gainer by it than she had expected. As Margaret gave much time and thought to art matters, and as the Allston exhibition was really an event of historic interest, some consideration of this paper will not be inappropriate in this place. Washington Allston was at that time, had long been, and long continued to be, the artist saint of Boston. A great personal prestige added its power to that of his unquestioned genius. Beautiful in appearance, as much a poet as a painter, he really seemed to belong to an order of beings who might be called "Too bright and good For human nature's daily food." He had flown into the heart of Europe when few American artists managed to get so far. He had returned to live alone with his dreams, of which one was the nightmare of a great painting which he never could finish, and never did. He had kept the vulgar world at a distance from his life and thought, intent on coining these into a succession of pictures which claimed to have a mission to the age. The series of female heads which are the most admirable of his works appeared to be the portraits of as many ideal women who, with no existence elsewhere, had disclosed themselves to him at his dreamy fireside or in his haunted studio. The spirit of the age, in its highest extreme, was upon him, and the wave of supervital aspiration swept him, as it did Channing and Emerson, beyond the region of the visible and sensible. At that day, and for ten years later, one might occasionally have seen in some street of Boston a fragile figure, and upon it a head distinguished by snowy curls and starry eyes. Here was the winter of age; here the perpetual summer of the soul. The coat and hat did not matter; but they were of some quaint, forgotten fashion, outlining the vision as belonging to the past. You felt a modesty in looking at anything so unique and delicate. I remember this vision as suddenly disclosed out of a bitter winter's day. And the street was Chestnut Street, and the figure was Washington Allston going to visit the poet Richard H. Dana. And not long afterwards the silvery snows melted, and the soul which had made those eyes so luminous shot back to its immortal sphere.
