At what period the four mysterious creatures in the vision of Ezekiel (ch. i. 5) were first adopted as significant symbols of the Four Evangelists, does not seem clear. The Jewish doctors interpreted them as figuring the four Archangels,—Michael, Raphael, Gabriel, Uriel; and afterwards applied them as emblems of the Four Great Prophets,—Isaiah, Jeremiah, Ezekiel, and Daniel. By the early Oriental Christians, who typified the whole of the Old Testament, the transfer of the emblem to the Four Evangelists seems obvious and easy; we find it alluded to as early as the second century. The four ‘Beasts’ of corresponding form in the Revelation (chap. iv. 7), which stood round the throne of the Lamb, were likewise thus interpreted; but it was not till the fifth century that we find these symbols assuming a visible form, and introduced into works of art. In the seventh century they had become almost universal, as distinctive attributes. [Illustration: 48 St. Matthew (Mosaic, fifth century)] The general application of the Four Creatures to the Four Evangelists is of much earlier date than the separate and individual application of each symbol, which has varied at different times; that propounded by St. Jerome, in his commentary on Ezekiel, has since his time prevailed universally. Thus, then, 1. To St. Matthew was given the CHERUB, or human semblance, because he begins his gospel with the human generation of Christ; or, according to others, because in his gospel the human nature of the Saviour is more insisted on than the divine. In the most ancient mosaics, the type is human, not angelic, for the head is that of a man with a beard. 2. St. Mark has the LION, because he has set forth the royal dignity of Christ; or, according to others, because he begins with the mission of the Baptist—‘_the voice of one crying in the wilderness_’—which is figured by the lion: or, according to a third interpretation, the lion was allotted to St. Mark, because there was, in the middle ages, a popular belief that the young of the lion was born dead, and after three days was awakened to vitality by the breath of its sire; some authors, however, represent the lion as vivifying his young not by his breath, but by his roar. In either case the application is the same; the revival of the young lion was considered as symbolical of the resurrection, and Mark was commonly called the ‘Historian of the Resurrection.’ Another commentator observes that Mark begins his gospel with ‘roaring’—‘the voice of one crying in the wilderness;’ and ends it fearfully with a curse—‘He that believeth not shall be damned;’ and that, therefore, his appropriate attribute is the most terrible of beasts, the lion.[101] 3. Luke has the OX, because he has dwelt on the priesthood of Christ, the _ox_ being the emblem of sacrifice. 4. John has the EAGLE, which is the symbol of the highest inspiration, because he soared upwards to the contemplation of the divine nature of the Saviour.
