the superb vase in the British Museum, No. 564 in Mr. Newton's Catalogue; but its variety of color defied photography, and after the sheets had gone to press I was compelled to reduce Le Normand's plate of it, which is unsatisfactory, but answers my immediate purpose.

The enlarged photographs for use in the Lecture Room were made for me with most successful skill by Sergeant Spackman, of South Kensington; and the help throughout rendered to me by Mr. Burgess is acknowledged in the course of the Lectures; though with thanks which must remain inadequate lest they should become tedious; for Mr. Burgess drew the subjects of Plates III., X., and XIII.; and drew and engraved every wood-cut in the book.

LECTURE I.

OF THE DIVISION OF ARTS.

November, 1870.

1. If, as is commonly believed, the subject of study which it is my special function to bring before you had no relation to the great interests of mankind, I should have less courage in asking for your attention to-day, than when I first addressed you; though, even then, I did not do so without painful diffidence. For at this moment, even supposing that in other places it were possible for men to pursue their ordinary avocations undisturbed by indignation or pity,—here, at least, in the midst of the deliberative and religious influences of England, only one subject, I am well assured, can seriously occupy your thoughts—the necessity, namely, of determining how it has come to pass that, in these recent days, iniquity the most reckless and monstrous can be committed unanimously, by men more generous than ever yet in the world's history were deceived into deeds of cruelty; and that prolonged agony of body and spirit, such as we should shrink from inflicting willfully on a single criminal, has become the appointed and accepted portion of unnumbered multitudes of innocent persons, inhabiting the districts of the world which, of all others, as it seemed, were best instructed in the laws of civilization, and most richly invested with the honor, and indulged in the felicity, of peace.

Believe me, however, the subject of Art—instead of being foreign to these deep questions of social duty and peril,—is so vitally connected with them, that it would be impossible for me now to pursue the line of thought in which I began these lectures, because so ghastly an emphasis would be given to every sentence by the force of passing events. It is well, then, that in the plan I have laid down for your study, we shall now be led into the examination of technical details, or abstract conditions of sentiment; so that the hours you spend with me may be times of repose from heavier thoughts. But it chances strangely that, in this course of minutely detailed study, I have first to set before you the most essential piece of human workmanship, the plow, at the very moment when—(you may see the announcement in the journals either of yesterday or the day before)—the swords of your soldiers have been sent for to be sharpened, and not at all to be beaten into plowshares. I permit myself, therefore, to remind you of the watchword of all my earnest writings—"Soldiers of the Plowshare, instead of Soldiers of the Sword,"—and I know it my duty to assert to you that the work we enter upon to-day is no trivial one, but full of solemn hope; the hope, namely, that among you there may be found men wise enough to lead the national passions towards the arts of peace, instead of the arts of war.

I say, the work "we enter upon," because the first four lectures I gave in the spring were wholly prefatory; and the following three only defined for you methods of practice. To-day we begin the systematic analysis and progressive study of our subject.

2. In general, the three great, or fine, Arts of Painting, Sculpture, and Architecture, are thought of as distinct from the lower and more mechanical formative arts, such as carpentry or pottery. But we cannot, either verbally, or with any practical advantage, admit such classification. How are we to distinguish painting on canvas from painting on china?—or painting on china from painting on glass?—or painting on glass from infusion of color into any vitreous substance, such as enamel?—or the infusion of color into glass and enamel from the infusion of color into wool or silk, and weaving of pictures in tapestry, or patterns in dress? You will find that although, in ultimately accurate use of the word, painting must be held to mean only the laying of a pigment on a surface with a soft instrument; yet, in broad comparison of the functions of Art, we must conceive of one and the same great artistic faculty, as governing every mode of disposing colors in a permanent relation on, or in, a solid substance; whether it be by tinting canvas, or dyeing stuffs; inlaying metals with fused flint, or coating walls with colored stone.

3. Similarly, the word 'Sculpture,'—though in ultimate accuracy it is to be limited to the development of form in hard substances by cutting away portions of their mass—in broad definition, must be held to signify the reduction of any shapeless mass of solid matter into an intended shape, whatever the consistence of the substance, or nature of the instrument employed; whether we carve a granite mountain, or a piece of box-wood, and whether we use, for our forming instrument, ax, or hammer, or chisel, or our own hands, or water to soften, or fire to fuse;—whenever and however we bring a shapeless thing into shape, we do so under the laws of the one great art of Sculpture.

4. Having thus broadly defined painting and sculpture, we shall see that there is, in the third place, a class of work separated from both, in a specific manner, and including a great group of arts which neither, of necessity, tint, nor for the sake of form merely, shape the substances they deal with; but construct or arrange them with a view to the resistance of some external force. We construct, for instance, a table with a flat top, and some support of prop, or leg, proportioned in strength to such weights as the table is intended to carry. We construct a ship out of planks, or plates of iron, with reference to certain forces of impact to be sustained, and of inertia to be overcome; or we construct a wall or roof with distinct reference to forces of pressure and oscillation, to be sustained or guarded against; and, therefore, in every
