The action passes in the days of Luther, and Luther's figure is seen in the background. It is rare to find a Romanticist writing of him with such warmth as this:--"As a mountain sends out streams to the east and to the west, so this man combined opposites, things that in others are never found together--humility and pride, conviction of the path he was bound to tread and willing acceptance of the advice of others, clear understanding and blind faith." A prominent part in the action is taken by Dr. Faust, the Faustus of popular legend, the famous doctor and alchemist. He is represented with a fiery red face, white hair, and bald crown, wearing scarlet trunk hose and ten orders. He is half-genius, half-charlatan, and works miraculous cures. The most beautifully drawn character is that of a woman, the hero's betrothed, Anna Zähringer, daughter of Apollonia, the love of his youth. She is the tall German maiden of powerful build and noble carriage, but she also possesses the sensuous attraction which Gottfried Keller has a special faculty of imparting to his young women. The hero of the story, Berthold, the burgomaster, is another personification of Arnim's personal ideal. He is of noble descent, but having grown up in humble circumstances, is simple and plain in all his ways, a good, upright, quiet citizen. Yet all the time he is at heart an aristocrat, who longs for armour and weapons and tournaments, and who actually, without previous training, wins the prize in the first tournament in which he takes part. Mystic incidents are, of course, not lacking. If Arnim could not forego them in his modern novel, in which we read of a priest who, with one look, imparted to childless wives the power of conception, they were certain to occur much more frequently, and to be of an even more surprising nature, in a tale of times long past. Faust, for instance, cures Berthold by injecting into his veins some of the blood of a stalwart young man, Anton by name, and ever after this, Berthold has the feeling that Anton has somehow acquired a right of possession in his, Berthold's, lady-love, Anna; and Anton himself immediately feels mysteriously attracted to Anna. _Die Kronenwächter_, like all Arnim's longer productions, is a piece of patchwork, though it must be allowed that the patchwork does not lack poetic value.
