Many years ago a celebrated writer, in speaking of Lord Byron, who had then been dead some years, said that so much had already been written upon him that the subject had almost become commonplace, but was far from being exhausted. This truth, indisputable when applied to Byron's genius, his works, and to his intellect, was then and still is equally positive when referring to his moral qualities. A subject as well as an object may become commonplace by the quantity, but nevertheless remain new and rare, owing to its quality. A subject can not be exhausted before it has been seen under every one of its various aspects, and appreciated in all its points. If much has been said of Lord Byron, has his truly noble character been fairly brought to light? Has he not, on the contrary, been judged rather as the author than the man, and have not the imaginary creations of his powerful mind been too much identified with reality? In the best biographies of his life do we not meet with many gaps which have to be filled up--nay, worse, gaps filled up with errors which have to be eradicated to make room for the truth? The object of this work is precisely to do away with these errors and to replace them by facts, and to dispel the shadows which fancy has raised around his name. For the old opinions we wish to substitute new appreciations, by weighing exactly the measure of truth which exists in the former; and by the logic of facts we wish to judge fairly so as to prevent posterity from being deceived. In doing this we do not pretend to give England any new information. For a long time, no doubt, error sprang from that country; but years and events have passed since that state of things existed. The liberal and tolerant spirit, enlightened by philosophy, which has spread all over liberal England, has also been reflected in the opinions formed of men, and has modified many pages of biography and history and made Englishmen feel how numerous were the wrongs of which they were guilty toward their illustrious countryman.
