In 1825, Moore appeared before the public in the character of a biographer, with the “Life of Sheridan,” which, though valuable and amusing, was not considered fully to establish his reputation in his new literary field. Indeed, it was the fashion of the day to say that Moore had murdered the marvelous and witty orator, whose skillfully-prepared and dexterously-delivered jokes had so often made the walls of St. Stephen shake and resound with laughter and merriment. “No!” exclaimed George IV., on hearing this grave charge; “but he has certainly attempted his life.” Lord Brougham says, that the frankness with which Moore gave the secret note-books of the famous wit to the world, must almost have made their author shake in his grave. Four years later, Moore was again an aspirant to public favor, with “Notices of the Life of Lord Byron.” From the large space which the poetic peer had during life filled in the eye of the world, and the extraordinary reputation he had left behind him, this work was, and could hardly fail to be, extremely interesting. Much had been expected, however, on account of the close friendship that had existed, and the frank intercourse that had taken place, between the distinguished writer and the hero whose sayings and doings his pen aspired to immortalize. Moreover, the mystery attached to the autobiography that had been destroyed was not forgotten. The literary enterprise, when executed, was not deemed quite satisfactory; it was encompassed with perplexing and insuperable difficulties, and the book was necessarily the reverse of faultless. In fact, even if he had the inclination, it was almost impossible for him to comment with any degree of freedom or severity on the failings and follies of a man with whom he had been long on terms so intimate; even if the danger and delicacy of the arduous task had not been indefinitely increased by respect and consideration for the feelings of many persons then still living.
