Byzantine patterns have a barbaric stamp, and yet have much of the grandiose about them; but they are to the last degree conventional. In the early mosaics, both in Constantinople and Rome, every face and head, every flower and animal, represents a type and not an individual.

Gothic foliage patterns, in England and elsewhere, are a struggle between the naturalistic and the conventional. The Norman style and the Romanesque, which preceded it, and from which it was modified and elevated, show their vegetable forms thick-stemmed and few-leaved, whereas the Gothic aspired to a developed gracefulness; and the Renaissance, which succeeded it, assumed all the freedom of natural flowers and plants, floating in the breeze, on their delicate stems. (Pl. [28].)

All the Renaissance patterns, which, as their name denotes, were born again, like butterflies to frolic for a day of gay enjoyment, are purely decorative. Their generally charming, graceful forms group together to cover empty spaces with every regard to the rules of design and composition, but without any inner meaning. If we take these arabesques to pieces, we generally find the parts come from various sources; and having served last in pagan Rome for pagan purposes, had been slightly refashioned for Christian decorative art,[125] before the Byzantine inartistic taste, and barbaric splendour of metal-work patterns, had extinguished all the gay fancy of the arts of Southern Europe.

The mediæval revival was a return to the light and fantastic, and a protest against the solemnity of all Gothic art, which had had its great day, had culminated, and died out. The patterns of the Renaissance are all guided by the principles of repetition and duplication, or that of doubling the pattern, which repeats itself to right and left, as if folded down the middle.

The principal lines thus echoed one another; but the artist was permitted to vary the conventionalism of the general forms of figures, flowers, fruit, or butterflies, so as to balance and yet differ in every detail.
