Nec minus hos scribas animalia et ipsa figurant.
This would again alter the received order of the symbols, and place the angelic or human semblance lower than the rest: but I have never seen them so placed, at least I can recollect no instance.
A Greek mosaic, existing in the Convent of Vatopedi, on Mount Athos, exhibits an attempt to reduce to form the wild and sublime imagery of the prophet Ezekiel: the Evangelists, or rather the Gospels, are represented as the tetramorph, or four-faced creature, with wings full of eyes, and borne on wheels of living flame (49).
The Tetramorph, i.e. the union of the four attributes of the Evangelists, in one figure, is in Greek Art always angelic or winged—a mysterious thing. The Tetramorph in Western Art has in some instances become monstrous, instead of mystic and poetical. In a miniature of the Hortus Deliciarum, we find the new Law, or Christianity, represented as a woman crowned and seated on an animal which, with the body of a horse, has the four heads of the mystic creatures; and of the four feet, one is human; one hoofed, for the ox; one clawed like an eagle’s; and one like a lion’s: underneath is inscribed Animal Ecclesiæ. In some other examples, the Church, or the new Law, is seated in a triumphal car drawn by the eagle, the lion, and the ox, while the angel holds the reins and drives as charioteer.
The early images of the Evangelical symbol are uniformly represented with wings, for the same reason that wings were given to the angels,—they were angels, i.e. bringers of good tidings: for instance, in the earliest example to which I can refer, a rude fragment of a bas-relief in terracotta, found in the catacombs, which represents a lamb with a glory holding a cross; on the right, an angel in a sacerdotal garment (St. Matthew), on the left the winged ox (St. Luke), each holding a book.
In the most ancient Christian churches we find these symbols perpetually recurring, generally in or over the recess at the east end (the apsis, or tribune), where stands the altar. And as the image of Christ, as the Redeemer, either under the semblance of the lamb, or in his human likeness, as a grand, calm, solemn figure enthroned, and in the act of benediction, forms invariably the principal object; almost as invariably the Evangelists are either at the four corners, or ranged in a line above or below, or they are over the arch in front of the tribune. Sometimes they are the heads only of the mystic creatures, on an azure ground, studded with stars, floating as in a firmament, thus (50): or the half figure ends in a leafy scroll, like the genii in an arabesque, as thus (51): or the creature is given at full length and entire, with four wings, holding the book, and looking much like a figure in heraldry (52, 53).
