Lowell's second marriage was as simple and inevitable as the first. Miss Dunlap was not an ordinary housekeeper, but the sister of one of Maria Lowell's most intimate friends, and she was such a pleasant, attractive lady that the wonder is rather he should have waited four years before concluding to offer himself. She was compared to the Greek bust called Clyte, because her hair grew so low down upon her forehead, and this was considered an additional charm.
Louisa Alcott had a story that at first she refused Lowell's offer on account of what people might say; and that then he composed a poem answering her objections in the form of an allegory, and that this finally convinced her. If he had considered material interests he would have married differently.
In November, 1857, the firm of Phillips & Sampson issued the first number of the Atlantic Monthly in the cause of high-minded literature,—a cause which ultimately proved to be their ruin. Lowell accepted the position of editor, and such a periodical as it proved to be under his guidance could not have been found in England, and perhaps not in the whole of Europe; but it could not be made to pay, and two years later Phillips & Sampson failed,—partly on that account, and partially the victims of a piratical opposition.
Lowell published Emerson's "Brahma" in spite of the shallow ridicule with which he foresaw it would be greeted; but when Emerson sent him his "Song of Nature" he returned it on account of the single stanza:
"One in a Judaean manger,
And one by Avon stream,
One over against the mouths of Nile,
And one in the Academe."
which he declared was more than the Atlantic could be held responsible for. Emerson, who really knew little as to what the public thought of him, was for once indignant. He said: "I did not know who had constituted Mr. Lowell my censor, and I carried the verses to Miss Caroline Hoar, who read them and said, that she considered those four lines the best in the piece." He permitted Lowell, however, to publish the poem without them, as may be seen by examining the pages of the Atlantic, and afterwards published the original copy in his "May Day."
Lowell's editorship of the North American Review, which followed after this, was not so successful. It was chiefly a political magazine at that time, and to understand politics in a large way—that is, sufficiently to write on the subject—one must not only be a close observer of public affairs, but also a profound student of history; and Lowell was neither. He was not acquainted with prominent men in public life, and depended too much on information derived at dinner-parties, or similar occasions. During the war period Sumner, Wilson, and Andrew were almost omnipotent in Massachusetts, for the three worked together in a common cause; but power always engenders envy and so an inside opposition grew up within the Republican party to which Lowell lent his assistance without being aware of its true character. His articles in the North American on public affairs were severely criticised by Andrew and Wilson, while Frank W. Bird frankly called them "giving aid and comfort to the enemy." It was certainly a doubtful course to pursue at such a critical juncture—when all patriots should have been united—and it offended a good many Republicans without conciliating the opposition. Lowell's successor in this editorial chair was an old Webster Whig who had become a Democrat.
In 1873 he resigned his professorship and went to Italy for a holiday. He said to some friends whom he met in Florence: "I am tired of being called Professor Lowell, and I want to be plain Mr. Lowell again. Eliot wanted to keep my name on the catalogue for the honor of the university, but I did not like the idea." This was true republicanism and worthy of a poet.
Lowell was little known on the continent, and he travelled in a quiet, unostentatious manner. He went to dine with his old friends, but avoided introductions, and remained at Florence nearly two months after other Americans had departed for Rome. The reason he alleged for this was that Rome was a mouldy place and the ruins made him feel melancholy; also, because he preferred oil paintings to frescos. He had just come from Venice, and spoke with enthusiasm of the mighty works of Tintoretto,— especially his small painting of the Visitation, above the landing of the staircase in the Scuola of San Rocco. He did not like the easel-paintings of Raphael on account of their hard outlines; those in the Vatican did him better justice. This idea he may have derived from William Morris Hunt, the Boston portrait-painter. He considered the action of the Niobe group too strenuous to be represented in marble.
Miss Mary Felton liked the Niobe statues; so Lowell said, "Now come back with me, and I will sit on you." Accordingly we all returned to the Niobe hall, where Lowell lectured us on the statues without, however, entirely convincing Miss Felton. Then we went to the hall in the Uffizi Palace, which is called the Tribune. Mrs. Lowell had never been in the Tribune, where the Venus de' Medici is enshrined; so her husband opened the door wide and said, "Now go in"—as if he were opening the gates of Paradise.
