The Dragon of the Apocalypse.
By Albert Dürer.

As a Christian emblem the dragon may be taken to symbolise the supreme spirit of evil, a veritable devil whom it was the special mission of militant saints to slay, as it had been the glory of the heroes of the pagan mythology to conquer. “In pictures of sacred and legendary subjects,” says a late writer, “the dragon usually formed an important feature. The evil thing was invariably depicted writhing under the foot of the saint, or transfixed with his triumphant spear. In like manner the virtues trampled tranquilly each on her complementary vice, embodied in the form of some impossible creature; and if the rigid virtues were sometimes insipid, it must be allowed that the demons were usually grotesquely characteristic, and often delightful in colour.”

The prostrate attitude usually signifies the triumph of Christianity over Paganism, as in pictures of St. George and St. Sylvester; or over heresy and schism, as when it was adopted as the emblem of the Knights of the Order of the Dragon, in Hungary, which was instituted for the purpose of contending against the adherents of John Huss and Jerome of Prague.

The dragon in Christian Art is often very variously represented, sometimes as a serpent, at other times as a dragon or wyvern, or again in the symbolic figure partly human, under which form we find the “old serpent” (the Devil) often represented, as in the conflict of St. Michael the Archangel. The numerous legends of saints who have fought and overcome dragons prove the symbolic light in which the impersonation of evil was generally viewed.

From ancient carving.

St. Margaret is the patron saint of the borough of Lynn Regis, and on the old corporation seal she is represented standing on a dragon and wounding it with a cross. The Latin inscription on the seal is “Sub Margaret teritur draco stat cruce læta.” The modern shield of the town is now blazoned: azure three conger’s (or dragon’s) heads erased and erect, the jaws of each pierced with a cross crosslet fitchée or. In paintings St. Margaret is represented as a young woman of great beauty bearing the martyr’s palm and olive crown, or with the dragon chained and helpless at her feet as an attribute. Sometimes she is depicted coming from the dragon’s mouth, for the legend says the monster swallowed her, but on her making the sign of the cross he was compelled to free her again. A legend states that Olybus, Governor of Antioch, captivated by the beauty of Margaret, wished to marry her; as she rejected him with scorn he threw her into a dungeon, where the devil appeared to her in the form of a horrible dragon and endeavoured to frighten her from her path. Margaret held up the cross and the dragon fled. Other legends say he burst asunder.
