These are the chief principles which we shall have to notice, as involved in the production of ornamental designs.

DIVISION III.

Some other principles of a less noble character than those which we have already noticed as entering into ornament yet remain to be mentioned. Man will be amused as well as instructed; he must be pleased as well as ennobled by what he sees. I hold it as a first principle that ornamentation, as a true fine art, can administer to man in all his varying moods, and under all phases of feeling. Decoration, if properly understood, would at once be seen to be a high art in the truest sense of the word, as it can teach, elevate, refine, induce lofty aspirations, and allay sorrows; but we have now to notice it as a fine art, administering to man in his various moods, rather than as the handmaid to religion or morals.

Humour seems to be as much an attribute of our nature as love, and, like it, varies in intensity with different individuals. There are few in whom there is not a certain amount of humour, and in some this one quality predominates over all others. It not unfrequently happens that men who are great thinkers are also great humorists—great talent and great humour being often combined in the one individual.

The feeling for humour is ministered to in ornament by the grotesque, and the grotesque occurs in the works of almost all ages and all peoples. The ancient Egyptians employed it, so did the Assyrians, the Greeks, and the Romans; but none of these nations used it to the extent of the artists of the Celtic, Byzantine, and "Gothic" periods. Hideous "evil spirits" were portrayed on the outside of almost every Christian edifice at one time, and much of the Celtic ornament produced by the early monks consisted of an anastomosis, or network, of grotesque creatures.

The old Irish crosses were enriched with this kind of ornamentation,[9] and some of the decorative embellishments of these works are of extraordinary interest; but those who have access to the beautiful work of Professor Westwood on Celtic manuscripts will there see this grotesque form of ornament to perfection. As regards the Eastern nations, while nearly all have employed the grotesque as an element of decorative art, the Chinese and Japanese have employed it most largely, and for it they manifest a most decided partiality. The drawings of dragons, celestial lions (always spotted), mythical birds, beasts, fishes, insects, and other supposed inhabitants of the Elysian plains, which these people produce, are most interesting and extraordinary.

Without in any way going into a history of the grotesque, let us look at the characteristic forms which it has assumed, and what is necessary to its successful production. We have said that the grotesque in ornament is the analogue of humour in literature. This is the case; but the grotesque may represent the truly horrible or repellent, and be simply repulsive. This form is so seldom required in ornamentation that I shall not dwell upon it, and when required it should always be associated with power; for if the horrible is feeble it cannot be corrective, but only revolting, like a miserable deformed animal.

I think it may be taken as a principle, that the further the grotesque is removed from an imitation of a natural object the better it is, provided that it be energetic and vigorous—lifelike. Nothing is worse than a feeble joke, unless it be a feeble grotesque. The amusing must appear to be earnest.
