The Heldenbuch, or Book of Heroes, which, in its present form, belongs to the close of the twelfth century, is a collection of poems, containing traditions of events which happened in the time of Attila, and the irruptions of the German nations into the Roman Empire. The principal personages who figure in these tales of love and war are Etzel or Attila, Dietrich or Theodoric the Great, Siegfried, the Achilles of the North, Gudrune, Hagan, and others, who reappear in the Nibelungen Lied, and who have been already alluded to in the heroic legends of the Scandinavian Edda. The Nibelungen Lied (from Nibelungen, the name of an ancient powerful Burgundian race, and Lied, a lay or song) occupies an important place in German literature, and in grandeur of design and beauty of execution it far surpasses any other poetical production of this period. The "Horny Siegfried," one of the poems of the Heldenbuch, serves as a sort of prelude to the Nibelungen. In that, Siegfried appears as the personification of manly beauty, virtue, and prowess; invulnerable, from having bathed in the blood of some dragons which he had slain, save in one spot between his shoulders, upon which a leaf happened to fall. Having rescued the beautiful Chriemhild from, the power of a giant or dragon, and possessed himself of the treasures of the dwarfs, he restores her to her father, the King of the ancient city of Worms, where he is received with regal honors, and his marriage with Chriemhild celebrated with unparalleled splendor.

In the Nibelungen, Chriemhild is represented as the sister of Günther the King of Burgundy; the gallant Siegfried having heard of her surpassing beauty, resolves to woo her for his bride, but all his splendid achievements fail to secure her favors. In the mean time tidings reach the court of the fame of the beautiful Brunhild, queen of Isenland, of her matchless courage and strength; every suitor for her hand being forced to abide three combats with her, and if vanquished to suffer a cruel death. Günther resolves to try his fortune, and to win her or perish, and Siegfried accompanies him on condition that the hand of Chriemhild shall be his reward if they succeed.

At the court of Brunhild, Siegfried presents himself as the vassal of Günther, to increase her sense of his friend's power, and this falsehood is one cause of the subsequent calamities. In the combats, Siegfried, becoming invisible by means of a magic cap he had obtained from the dwarfs, seizes the arm of Günther and enables him to overcome the martial maid in every feat of arms: and the vanquished Brunhild bids her vassals do homage to him as their lord. A double union is now celebrated with the utmost pomp and rejoicing. The proud Brunhild, however, is indignant at her sister-in-law wedding a vassal. In vain Günther assures her that Siegfried is a mighty prince in his own country; the offended queen determines to punish his deception, and ties him hand and foot with her magic girdle, and hangs him upon a nail; Siegfried pitying the condition of the king, promises his aid in depriving the haughty queen of the girdle, the source of all her magic strength. He successfully accomplishes the feat, and in a luckless hour presents the trophy to Chriemhild, and confides the tale to her ear. A dispute having afterwards arisen between the two queens, Chriemhild, carried away by pride and passion, produces the fatal girdle, a token which, if found in the possession of any save the husband, was regarded as an almost irrefutable proof of guilt among the nations of the North. At this Brunhild vows revenge, and is aided by the fierce Hagan, Günther's most devoted follower, who, having induced Chriemhild to confide to him the secret of the spot where Siegfried is mortal, seizes the first occasion to plunge a lance between his shoulders, and afterwards bears the body to the chamber door of Chriemhild, who is overwhelmed with grief and burning with resentment. To secure her revenge she at length marries Etzel, or Attila, king of the Huns, who invites the Burgundians to his court, and at a grand festival Chriemhild involves them in a bloody battle, in which thousands are slain on both sides. Günther and Hagan are taken prisoners by Dietrich of Berne, and put to death by Chriemhild, who in turn suffers death at the hands of one of the followers of Dietrich.

Such is an imperfect outline of this ancient poem, which, despite all its horrors and improbabilities, has many passages of touching beauty, and wonderful power. Siegfried, the hero, is one of the most charming characters of romance or poetry. Chriemhild, at first all that the poet could fancy of loveliness, becomes at last an avenging fury. Brunhild is proud, haughty, stern, and vindictive, though not incapable of softer emotions.

In the Scandinavian legend we find the same personages in grander outlines and more gigantic proportions. The mythological portion of the story occupies the most prominent place, and Brunhild is there represented as a Valkyriur.

The time in which the scene of this historical tragedy is laid is about 430 A.D. From the thirteenth to the sixteenth century it was widely read, and highly appreciated. But in the succeeding age it was almost entirely forgotten. It was brought again to light in the beginning of the present century, and since that time, it has been the subject of many learned commentaries and researches.

4. THE FOURTEENTH AND FIFTEENTH CENTURIES.—The period from the accession of the House of Hapsburg to the beginning of the Reformation was crowded with events of great social importance, but its literature was remarkably poor. The palmy days of the minstrels and romancists had passed away. Rudolph was an economical prince, who mended his own doublet to spare money, and as he had no taste for minstrelsy, the composers of songs who went to his court found no rewards there. The rank and influence of the metropolis were transferred from Frankfort to Vienna, and the communication with the southern and southwestern parts of Europe was greatly impeded. The Germans were occupied in crusades against the Huns; the court language was changed from west Gothic to an east Gothic dialect, which was less national, and much of the southern culture and the European sympathies which had characterized the reign of the Suabian emperors disappeared.

Some inferior princes, however, encouraged versification, but the prizes were so reduced in value that the knights and noblemen left the field in favor of inferior competitors. A versifying mania now began to pervade all classes of society; chaplains, doctors, schoolmasters, weavers, blacksmiths, shoemakers—all endeavored to mend their fortunes by rhyming. Poetry sank rapidly into dullness and mediocrity, while the so-called poets rose in conceit and arrogance. The spirit of the age soon embodied these votaries of the muse in corporations, and the Emperor Charles IV. (1346-1378) gave them a charter. They generally called twelve poets among the minnesingers their masters, and hence their name Mastersingers. They met on certain days and criticised each other's productions. Correctness was their chief object, and they seemed to have little idea of the difference between poetical and prosaic expressions. Every fault was marked, and he who had fewest received the prize, and was allowed to take apprentices in the art. At the expiration of his poetical apprenticeship the young poet was admitted to the corporation and declared a master.

Though the institution of the Mastersingers was established at the close of the thirteenth century, it was not until the fifteenth and sixteenth that it really flourished, particularly through the genius of Hans Sachs. The institution, survived, however, though languishing, through the seventeenth century, and the calamities of the Thirty Years' War. At Ulm it outlasted even the changes which the French Revolution effected in Europe, and as late as 1830 twelve old Mastersingers yet remained, who, after being driven from one asylum to another, sang their ancient melodies from memory in the little hostelry where the workmen used to meet in the evening to drink together. In 1839 four only were living, and in that year these veterans assembled with great solemnity, and declaring the society of Mastersingers forever closed, presented their songs, hymns, books, and pictures to a modern musical institution at Ulm.

While the early Mastersingers were pouring forth their strains with undiminished confidence in their own powers, a new species of poetic literature was growing up beside them in the form of simple and humorous fables, or daring satires, often directed against the clergy and nobility, which were among the most popular productions of the Middle Ages. Such were "Friar Amis" and the "Ship of Fools." Indeed, from the year 1300 to the era of the Reformation, we may clearly trace the progress of a school of lay doctrine which was opposed to a great part of the teaching of the church, and which was yet allowed to prevail among the people.
