The fourth group, though introduced from a foreign source, gives the special character and much of the charm of the period we consider. This is the sphere of legends derived from ecclesiastical ground. One of the best German writers on the history of German literature remarks: “If the aim and nature of all poetry is to let yourself be filled by a subject and to become penetrated with it; if the simple representation of unartificial, true, and glowing feelings belongs to its most beautiful adornments; if the faithful direction of the heart to the invisible and eternal is the ground on which at all times the most lovely flowers of poetry have sprouted forth, these legendary poems of early Germany, in their lovely heartiness, in their unambitious limitation, and their pious sense, deserve a friendly acknowledgment. What man has considered the pious images in the prayer-books of the Middle Ages, the unadorned innocence, the piety and purity, the patience of the martyrs, the calm, heavenly transparency of the figures of the holy angels, without, being attracted by the simple innocence and humility of these forms, the creation of pious artists’ hands? Who has beheld them without tranquil joy at the soft splendor poured over them, without deep sympathy, nay, without a certain emotion and tenderness? And the same spirit that created these images also produced those poetical effusions, the same spirit of pious belief, of deep devotion, of heavenly longing. If we make a present reality of the heroic songs of the early German popular poetry, and the chivalrous epics of the art poetry, the military expeditions and dress of the Crusades, this legendary poetry appears as the invention of humble pilgrims, who wander slowly on the weary way to Jerusalem, with scollop and pilgrim’s staff, engaged in quiet prayer, till they are all to kneel at the Saviour’s sepulchre; and thus contented, after touching the holy earth with their lips, they return, poor as they were, but full of holy comfort, to their distant home.
