One more text from the mythologists is to the same purpose,—_Beauty rides on a lion_. Beauty rests on necessities. The line of beauty is the result of perfect economy. The cell of the bee is built at that angle which gives the most strength with the least wax; the bone or the quill of the bird gives the most alar strength, with the least weight. "It is the purgation of superfluities," said Michel Angelo. There is not a particle to spare in natural structures. There is a compelling reason in the uses of the plant, for every novelty of color or form: and our art saves material, by more skilful arrangement, and reaches beauty by taking every superfluous ounce that can be spared from a wall, and keeping all its strength in the poetry of columns. In rhetoric, this art of omission is a chief secret of power, and, in general, it is proof of high culture, to say the greatest matters in the simplest way. Veracity first of all, and forever. _Rien de beau que le vrai_. In all design, art lies in making your object prominent, but there is a prior art in choosing objects that are prominent. The fine arts have nothing casual, but spring from the instincts of the nations that created them. Beauty is the quality which makes to endure. In a house that I know, I have noticed a block of spermaceti lying about closets and mantel-pieces, for twenty years together, simply because the tallow-man gave it the form of a rabbit; and, I suppose, it may continue to be lugged about unchanged for a century. Let an artist scrawl a few lines or figures on the back of a letter, and that scrap of paper is rescued from danger, is put in portfolio, is framed and glazed, and, in proportion to the beauty of the lines drawn, will be kept for centuries. Burns writes a copy of verses, and sends them to a newspaper, and the human race take charge of them that they shall not perish. As the flute is heard farther than the cart, see how surely a beautiful form strikes the fancy of men, and is copied and reproduced without end. How many copies are there of the Belvedere Apollo, the Venus, the Psyche, the Warwick Vase, the Parthenon, and the Temple of Vesta? These are objects of tenderness to all. In our cities, an ugly building is soon removed, and is never repeated, but any beautiful building is copied and improved upon, so that all masons and carpenters work to repeat and preserve the agreeable forms, whilst the ugly ones die out.
