PREFACE.

The following Lectures are printed, as far as possible, just as they
were delivered. Here and there a sentence which seemed obscure has been
mended, and the passages which had not been previously written, have
been, of course imperfectly, supplied from memory. But I am well assured
that nothing of any substantial importance which was said in the
lecture-room, is either omitted, or altered in its signification; with
the exception only of a few sentences struck out from the notice of the
works of Turner, in consequence of the impossibility of engraving the
drawings by which they were illustrated, except at a cost which would
have too much raised the price of the volume. Some elucidatory remarks
have, however, been added at the close of the second and fourth
Lectures, which I hope may be of more use than the passages which I was
obliged to omit.

The drawings by which the Lectures on Architecture were illustrated have
been carefully reduced, and well transferred to wood by Mr. Thurston
Thompson. Those which were given in the course of the notices of schools
of painting could not be so transferred, having been drawn in color; and
I have therefore merely had a few lines, absolutely necessary to make
the text intelligible, copied from engravings.

I forgot, in preparing the second Lecture for the press, to quote a
passage from Lord Lindsay's "Christian Art," illustrative of what is
said in that lecture (Sec. 52), respecting the energy of the mediaeval
republics. This passage, describing the circumstances under which the
Campanile of the Duomo of Florence was built, is interesting also as
noticing the universality o
