And Henry II., of Glanvill and Suger, of Abelard and Maimonides, of Frederick Barbarossa and Alexander III., of the emancipation of French communes and cities and the independence of those of Lombardy, of the growth of gilds and the extension of commerce, of trouvere and troubadour and the beginnings of vernacular literature, of the creation of Gothic art, of trial by jury and the supremacy of royal justice.
The trouvere, however, omits the greater part of the wanderings of Aeneas, and adorns his narrative with gorgeous descriptions, with accounts of the marvellous properties of beasts and stones, and of single combats among the knights who figure in the story.
This battle, sung by an unknown trouvere and retold with variations by Froissart, was an episode in the struggle for the succession to the duchy of Brittany between Charles of Blois, supported by the king of France, and John of Montfort, supported by the king of England.
There is no evidence to show whether Marie was of noble origin or simply pursued the profession of a trouvere for her living.
