X. Inscriptions appear sometimes to be introduced for the sake of the scroll on which they are written; and in late and modern painted glass, as well as in architecture, these scrolls are flourished and turned hither and thither as if they were ornamental. Ribands occur frequently in arabesques,--in some of a high order, too,--tying up flowers, or flitting in and out among the fixed forms. Is there anything like ribands in nature? It might be thought that grass and sea-weed afforded apologetic types. They do not. There is a wide difference between their structure and that of a riband. They have a skeleton, an anatomy, a central rib, or fibre, or framework of some kind or another, which has a beginning and an end, a root and head, and whose make and strength effects every direction of their motion, and every line of their form. The loosest weed that drifts and waves under the heaving of the sea, or hangs heavily on the brown and slippery shore, has a marked strength, structure, elasticity, gradation of substance; its extremities are more finely fibred than its centre, its centre than its root; every fork of its ramification is measured and proportioned; every wave of its languid lines is love. It has its allotted size, and place, and function; it is a specific creature. What is there like this in a riband? It has no structure: it is a succession of cut threads all alike; it has no skeleton, no make, no form, no size, no will of its own. You cut it and crush it into what you will. It has no strength, no languor. It cannot fall into a single graceful form. It cannot wave, in the true sense, but only flutter: it cannot bend, in the true sense, but only turn and be wrinkled. It is a vile thing; it spoils all that is near its wretched film of an existence. Never use it. Let the flowers come loose if they cannot keep together without being tied; leave the sentence unwritten if you cannot write it on a tablet or book, or plain roll of paper. I know what authority there is against me. I remember the scrolls of Perugino's angels, and the ribands of Raphael's arabesques, and of Ghiberti's glorious bronze flowers: no matter; they are every one of them vices and uglinesses. Raphael usually felt this, and used an honest and rational tablet, as in the Madonna di Fuligno. I do not say there is any type of such tablets in nature, but all the difference lies in the fact that the tablet is not considered as an ornament, and the riband, or flying scroll, is. The tablet, as in Albert Durer's Adam and Eve, is introduced for the sake of the writing, understood and allowed as an ugly but necessary interruption. The scroll is extended as an ornamental form, which it is not, nor ever can be.
