and León, the margraves of Montferrat and Este, the French royal court where Eleonore of Poitou was queen, and the court of England under Henry II, the second husband of Queen Eleonore, provided rallying centres. Even the sovereigns themselves were ambitious for the favor of the Muses. The earliest Troubadour of prominence was Guillaume, count of Poitiers (1087-1127). Contemporary with him was Robert, duke of Normandy, the son of William the Conqueror, who, after returning from the Crusade (1106), was till his death a prisoner of his brother Henry I of England in the Castle of Cardiff, where he is said to have attained the rank of a Welsh bard. This remarkable and sudden flowering of lyric poetry among the knighthood of the eleventh century, continuing for two centuries and more the record of which stands brightly emblazoned upon the shield of musical history, has never been satisfactorily explained. Riemann thinks that the education of the young nobility in the monasteries certainly had a refining influence. The familiarity with old Breton and British literature, the legend of King Arthur’s Round Table, the old Celtic narrative poems and romances, especially the legend of Tristan and Yseult, which were known through old French adaptations, likewise had an influence. By their own testimony, however, the Provençal poets found their immediate suggestions in folk song itself, as interpreted by the _jongleurs_. The latter’s entire repertoire of classic and mediæval chronicles was adopted by the Troubadours, whose own experiences in the Crusades later caused them to substitute recent chivalric deeds for antique subjects. The forms of the _jongleurs’_ art we find again in the Troubadour creations, but refined in style, governed by definite laws of poetry, more exalted in sentiment, so that, without sacrifice of spontaneity, they have gained distinction and variety and have become conscious works of art. As we are concerned here only with their musical significance, which, indeed, has been generally ignored by literary historians and underestimated by musicians, we shall have little to say about these forms; for, great as is the variety of their content, we fail to find parallel distinctions in their musical settings. It should not be overlooked, however, that certain poetic devices and ingenuities gave rise to more advanced musical forms, i. e., the repetition of a phrase on two rhyming verses at the beginning of a song, followed by a variant, which is the elementary form of the _Lied_.
