In a fragment of a novel, written by Byron in 1817, we have a corroboration of this assertion:--"A few days after, she set out for Aragon, with my son, on a visit to her father and mother. I did not accompany her immediately, having been in Aragon before.... During her journey I received a very affectionate letter from Donna Josepha, apprising me of the welfare of herself and my son. On her arrival at the château, I received another, still more affectionate, pressing me, in very fond and rather foolish terms, to join her immediately. As I was preparing to set out from Seville, I received a third--this was from her father, Don José di Cardozo, who requested me, in the politest manner, to dissolve our marriage. I answered him, with equal politeness, that I would do no such thing. A fourth letter arrived--it was from Donna Josepha, in which she informed me that her father's letter was written by her particular desire. I requested the reason by return of post: she replied, by express, that as reason had nothing to do with the matter, it was unnecessary to give any--but that she was an injured and excellent woman. I then inquired why she had written to me the two preceding affectionate letters, requesting me to come to Aragon. She answered, that was because she believed me out of my senses--that, being unfit to take care of myself, I had only to set out on this journey alone, and, making my way without difficulty to Don José di Cardozo's, I should there have found the tenderest of wives and--a strait-waistcoat."

When it became known that Byron's wife had left him, a sudden and complete change in the attitude of the public towards him took place. He had awakened one morning after the publication of _Childe Harold_ to find himself famous; now came a morning when he awoke to find himself infamous, regarded by society as an outlaw.

Chief among the causes of this revulsion was envy--not that envy in the hearts of the gods which the ancients regarded as the cause of the downfall of the great--but foul, base envy in the breasts of his fellow-men. He stood so high; he was so great; with all his faults he had never sunk to the level of vulgar, mechanical respectability; confident in his powers and the favour of fortune, he had never deigned to seek friends who could protect him, or heeded how many enemies he made. These latter had long been innumerable. Chief among the envious were his literary rivals; and amongst all the many species of envy, the envy of authors is one of the most venomous. He had derided them, had called them the writers of a decadent period, had taken from some the name they had won, and made it impossible for others to win a name--why should he be admired and idolised whilst they were in vain arranging their locks for the reception of a wreath which never came? What joy to be able to tear him from the golden throne of fame and besmirch him with the mud in which they themselves stood!
