Such evidences in favor of an argument could not fail to persuade me to undertake the desired elucidating task; feeling, indeed, particularly pleased to adopt, in my turn, a successful example from the once Great Unknown--now the not less great avowed author of the Waverley Novels, in the person of Sir Walter Scott, who did me the honor to adopt the style or class of novel of which "Thaddeus of Warsaw" was the first,--a class which, uniting the personages and facts of real history or biography with a combining and illustrative machinery of the imagination, formed a new species of writing in that day, and to which Madame de Staël and others have given the appellation of "an epic in prose." The day of its appearance is now pretty far back: for "Thaddeus of Warsaw" (a tale founded on Polish heroism) and the "Scottish Chiefs" (a romance grounded on Scottish heroism) were both published in England, and translated into various languages abroad, many years before the literary wonder of Scotland gave to the world his transcendent story of Waverley, forming a most impressive historical picture of the last struggle of the papist, but gallant, branch of the Stuarts for the British throne. [Footnote: It was on the publication of these, her first two works, in the German language that the authoress was honored with being made a lady of the Chapter of St. Joachim, and received the gold cross of the order from Wirtemburg.] "Thaddeus of Warsaw" being the first essay, in the form of such an association between fact and fancy, was published by its author with a natural apprehension of its reception by the critical part of the public. She had not, indeed, written it with any view to publication, but from an almost resistless impulse to embody the ideas and impressions with which her heart and mind were then full. It was written in her earliest youth; dictated by a fervent sympathy with calamities which had scarcely ceased to exist, and which her eager pen sought to portray; and it was given to the world, or rather to those who might feel with her, with all the simple-hearted enthusiasm which saw no impediment when a tale of virtue or of pity was to be told. In looking back through the avenue of life to that time, what events have occurred, public and private, to the countries and to the individuals named in that tale! to persons of even as lofty names and excellences, of our own and other lands, who were mutually affected with me in admiration and regret for the virtues and the sorrows described! In sitting down now to my retrospective task, I find myself writing this, my second preface to the story of "Thaddeus of Warsaw," just thirty years from the date of its first publication. Then, I wrote when the struggle for the birthright independence of Poland was no more; when she lay in her ashes, and her heroes in their wounds; when the pall of death spread over the whole country, and her widows and orphans travelled afar.
