Dr. Rock tells us that the symbolism of Scripture texts was given to the world in a book by St. Melito, Bishop of Sardis, A.D. 170. Its title is “The Key.”[537] In the fourth century were produced two great works on Scriptural symbols, that of St. Basil in his homilies on the six days of the creation, and that by St. Ambrose; both entitled Hexameron.
We meet this subject at every turn in the succeeding centuries, till in the twelfth we find it formulated and divided into branches—Bestiaria, Volucraria, and Lapidaria—and each type had frequently more than one meaning. Thus a lion represented power, sovereignty, dominion; also the “House of Judah;” a hare the emblem of man’s soul; a peacock that of wisdom (many-eyed). The ruby represents love. The pearl, innocence. The twelve stones in a breastplate, the twelve tribes of Israel.[538] Trees and flowers had also their symbolical meanings, though we are not aware of their being recorded in any mediæval book. We know that the vine is the tree of life; the stem of Jesse, the sacramental emblem; that the lily stands for purity, the woodbine for chastity, and the rose for religious ecstasy. The crowned lily was always the special emblem of the Virgin.
These symbols had many of them a distant source, and had been, as I have already indicated, emblematic of other inner meanings in the expression of pagan faiths. The tree of life was Babylonian; the horn, Persian; the fire-sticks of the prehistoric cross, Egyptian or Indian; and the composite animals representing many qualities, Ninevite (probably Accadian).[539]
All these were utilized, so that their already accepted uses should be helps and adjuncts, instead of impediments to the appreciation of divine truths; in the same way that “all that was lovely and of good repute” in the belief and morals of the ancient peoples, reasserted and purified, was claimed by the new teachers as types and antitypes. The symbolism of colours has been always considered very important in liturgical decoration,[540] and their meanings are discussed in the chapter on [colour].
The mystical colours, as has been already stated, are five—red, blue, purple, white, and gold. These the Christian Church inherited from the Levitical law, and continued faithful to them till the modern Roman use introduced green and black. The Church of England before the Reformation never allowed any but the original five mystic colours.
The symbolism of ecclesiastical embroideries, as well as that of all Christian art, being intended to illustrate the truths of Christianity by the teaching of the eye, the great symbol of our faith, the Cross, naturally drew to itself all its prehistoric forms as being the prophetic types of the “true cross.”
The earliest form of the prehistoric cross,
, is supposed to refer to the worship of the sun, and is said to be formed of two fire-sticks (for producing fire by friction) laid across each other. This is almost universal in prehistoric, archaic, classical, and Christian art to the thirteenth century. The next most ancient form is a broken cross, thus,
