Thomas Moore, who had the Memoirs[3] supposed to have thrown light on the mystery, in the full knowledge of Dr. Lushington's judgment and all the gossip of the day, professes to believe that "the causes of disunion did not differ from those that loosen the links of most such marriages," and writes several pages on the trite theme that great genius is incompatible with domestic happiness. Negative instances abound to modify this sweeping generalization; but there is a kind of genius, closely associated with intense irritability, which it is difficult to subject to the most reasonable yoke; and of this sort was Byron's. His valet, Fletcher, is reported to have said that "Any woman could manage my lord, except my lady;" and Madame De Staël, on reading the _Farewell_, that "She would have been glad to have been in Lady Byron's place." But it may be doubted if Byron would have made a good husband to any woman; his wife and he were even more than usually ill-assorted. A model of the proprieties, and a pattern of the learned philanthropy of which in her sex he was wont to make a constant butt, she was no fit consort for that "mens insana in corpore insano." What could her stolid temperament conjecture of a man whom she saw, in one of his fits of passion, throwing a favourite watch under the fire, and grinding it to pieces with a poker? Or how could her conscious virtue tolerate the recurring irregularities which he was accustomed, not only to permit himself, but to parade? The harassment of his affairs stimulated his violence, till she was inclined to suspect him to be mad. Some of her recently printed letters--as that to Lady Anne Barnard, and the reports of later observers of her character--as William Howitt, tend to detract from the earlier tributes to her consistent amiability, and confirm our ideas of the incompatibility of the pair. It must have been trying to a poet to be asked by his wife, impatient of his late hours, when he was going to leave off writing verses; to be told he had no real enthusiasm; or to have his desk broken open, and its compromising contents sent to the persons for whom they were least intended. The smouldering elements of discontent may have been fanned by the gossip of dependants, or the officious zeal of relatives, and kindled into a jealous flame by the ostentation of regard for others beyond the circle of his home. Lady Byron doubtless believed some story which, when communicated to her legal advisers, led them to the conclusion that the mere fact of her believing it made reconciliation impossible; and the inveterate obstinacy which lurked beneath her gracious exterior, made her cling through life to the substance--not always to the form, whatever that may have been--of her first impressions. Her later letters to Mrs. Leigh, as that called forth by Moore's _Life_, are certainly as open to the charge of self-righteousness, as those of her husband's are to self-disparagement.
