The first of these is our not understanding the scope and dignity of Decorative design. With all our talk about it, the very meaning of the words "Decorative art" remains confused and undecided. I want, if possible, to settle this question for you to-night, and to show you that the principles on which you must work are likely to be false, in proportion as they are narrow; true, only as they are founded on a perception of the connection of all branches of art with each other.

Observe, then, first—the only essential distinction between Decorative and other art is the being fitted for a fixed place; and in that place, related, either in subordination or command, to the effect of other pieces of art. And all the greatest art which the world has produced is thus fitted for a place, and subordinated to a purpose. There is no existing highest-order art but is decorative. The best sculpture yet produced has been the decoration of a temple front—the best painting, the decoration of a room. Raphael's best doing is merely the wall- colouring of a suite of apartments in the Vatican, and his cartoons were made for tapestries. Correggio's best doing is the decoration of two small church cupolas at Parma; Michael Angelo's of a ceiling in the Pope's private chapel; Tintoret's, of a ceiling and side wall belonging to a charitable society at Venice; while Titian and Veronese threw out their noblest thoughts, not even on the inside, but on the outside of the common brick and plaster walls of Venice.

Get rid, then, at once of any idea of Decorative art being a degraded or a separate kind of art. Its nature or essence is simply its being fitted for a definite place; and, in that place, forming part of a great and harmonious whole, in companionship with other art; and so far from this being a degradation to it—so far from Decorative art being inferior to other art because it is fixed to a spot—on the whole it may be considered as rather a piece of degradation that it should be portable. Portable art—independent of all place—is for the most part ignoble art. Your little Dutch landscape, which you put over your sideboard to-day, and between the windows tomorrow, is a far more contemptible piece of work than the extents of field and forest with which Benozzo has made green and beautiful the once melancholy arcade of the Campo Santo at Pisa; and the wild boar of silver which you use for a seal, or lock into a velvet case, is little likely to be so noble a beast as the bronze boar who foams forth the fountain from under his tusks in the market-place of Florence. It is, indeed, possible that the portable picture or image may be first-rate of its kind, but it is not first-rate because it is portable; nor are Titian's frescoes less than first-rate because they are fixed; nay, very frequently the highest compliment you can pay to a cabinet picture is to say—"It is as grand as a fresco."

Keeping, then, this fact fixed in our minds,—that all art may be decorative, and that the greatest art yet produced has been decorative,—we may proceed to distinguish the orders and dignities of decorative art, thus:—

I. The first order of it is that which is meant for places where it cannot be disturbed or injured, and where it can be perfectly seen; and then the main parts of it should be, and have always been made, by the great masters, as perfect, and as full of nature as possible.

You will every day hear it absurdly said that room decoration should be by flat patterns—by dead colours—by conventional monotonies, and I know not what. Now, just be assured of this—nobody ever yet used conventional art to decorate with, when he could do anything better, and knew that what he did would be safe. Nay, a great painter will always give you the natural art, safe or not. Correggio gets a commission to paint a room on the ground floor of a palace at Parma: any of our people—bred on our fine modern principles—would have covered it with a diaper, or with stripes or flourishes, or mosaic patterns. Not so Correggio: he paints a thick trellis of vine-leaves, with oval openings, and lovely children leaping through them into the room; and lovely children, depend upon it, are rather more desirable decorations than diaper, if you can do them—but they are not quite so easily done. In like manner Tintoret has to paint the whole end of the Council Hall at Venice. An orthodox decorator would have set himself to make the wall look like a wall—Tintoret thinks it would be rather better, if he can manage it, to make it look a little like Paradise;— stretches his canvas right over the wall, and his clouds right over his canvas; brings the light through his clouds—all blue and clear—zodiac beyond zodiac; rolls away the vaporous flood from under the feet of saints, leaving them at last in infinitudes of light—unorthodox in the last degree, but, on the whole, pleasant.

And so in all other cases whatever, the greatest decorative art is wholly unconventional—downright, pure, good painting and sculpture, but always fitted for its place; and subordinated to the purpose it has to serve in that place.

II. But if art is to be placed where it is liable to injury—to wear and tear; or to alteration of its form; as, for instance, on domestic utensils, and armour, and weapons, and dress; in which either the ornament will be worn out by the usage of the thing, or will be cast into altered shape by the play of its folds; then it is wrong to put beautiful and perfect art to such uses, and you want forms of inferior art, such as will be by their simplicity less liable to injury; or, by reason of their complexity and continuousness, may show to advantage, however distorted by the folds they are cast into.

And thus arise the various forms of inferior decorative art, respecting which the general law is, that the lower the place and office of the thing, the less of natural or perfect form you should have in it; a zigzag or a chequer is thus a better, because a more consistent ornament for a cup or platter than a landscape or portrait is: hence the general definition of the true forms of conventional ornament is, that they consist in the bestowal of as much beauty on the object as shall be consistent with its Material, its Place, and its Office.

Let us consider these three modes of consistency a little.
