Byron's Memoirs, written between 1818 and 1821 but never published and destroyed soon after his death, recounted at full-length his life, loves and opinions. He gave the manuscript to the poet Thomas Moore, who in turn sold it to John Murray with the intention that it should eventually be published. On Lord Byron's death in 1824, Moore, Murray, John Cam Hobhouse, and other friends who were concerned for his reputation gathered together and burned the original manuscript and the only known copy of it, in what has been called the greatest literary crime in history.
Since the Memoirs are lost beyond recovery, only the vaguest idea of their nature can be gathered from the mutually inconsistent testimony of those contemporaries of Byron who read them in manuscript. It is hard to judge how sexually explicit they were, some witnesses maintaining that they were perfectly fit for anyone to read and others that they were far too scabrous ever to be published.
