The French poems Troie, Thèbes, and Énéas, contemporaneous with one another in the sixth and seventh decades of the twelfth century, have many characteristics in common. They each repeat in a modernized form, and with incidents and details suited to their own age, the story of one of the great epics of classical antiquity, the Iliad, the Thebaid, and the Aeneid. They also combine with this traditional outline of adventure and conquest the narrative of romantic love and courtship, as conceived by Western Europe in the Middle Ages. And finally they each and all show an effort to attain some degree of excellence in style and composition. Thus they form a class by themselves, animated, as they are, by the same spirit and having the same purpose in view, and are the first exponents in the modern tongues of the ideals of chivalry. The sources of these poems, therefore, are an object of unusual interest to the student of mediaeval literature.
