The greater portion of the following work originally appeared in the columns of the _Illustrated London News_. The beauty of the sketches, and the permanent interest attached to them, led the proprietors of the _National Illustrated Library_ to believe that a reprint of them would form a valuable and welcome addition to that series of illustrated works. The various articles have accordingly been carefully revised by the author; many additions have been made, and curious extracts from rare old works have been introduced, more completely to illustrate the various scenes and objects described. The engravings, which consist chiefly of views of churches and other public buildings, of antiquities, views of streets and markets, sketches of street scenes, &c., have been carefully executed from original drawings. The work is not to be considered as a guide-book, but as a series of sketches in "poetic prose" of various parts of London, in which, while perfect accuracy is preserved, the dulness of a mere itinerary is avoided; in which London of the _present_ is sketched from constant personal observation, and London of the _past_ from the rich historical and legendary lore that exists regarding it, and in which the thoughts that arise in "a free mind and loving heart," from a contemplation of the various objects and scenes described, are expressed in eloquent and forcible language. Nor must the work be considered as exhaustive of the subject. The places and scenes chosen for "Picturesque Sketches" are chiefly in the eastern or older part of London. To have included the whole of the metropolis would have required not one volume, but many. Nevertheless, it will be found that the subjects to which chapters are devoted are the most interesting in London, and that though the work is not complete as regards the whole of this mighty city, yet each chapter is complete as far as regards its individual subject. _227 Strand, July 1, 1852._ PICTURESQUE SKETCHES OF LONDON. Ancient London. Instead of wasting words on traditions which few can believe, or filling my pages with accounts of the fabulous kings who are said to have descended from Æneas, and to have reigned in Britain centuries before the Roman Invasion, I shall commence the present work by shewing that the remote past will ever remain a mystery which man is not permitted to penetrate. The following opening to my _History of the Anglo-Saxons_ applies to the "unknown" origin of London--the new Troy of ancient fiction--the Augusta of the Romans--for in it I have described my impression of the unwritten History of the Past:
