The most remarkable works of the first period have been already alluded to. This period may possibly have produced original epics of the Chanson form, though, as has been pointed out, no indications of any such exist, except in the solitary instance of _Girartz de Rossilho_. The important poem of Auberi of Besancon on Alexander is lost, except the first hundred verses. It is thought to be the oldest vernacular poem on the subject, and is in a mixed dialect partaking of the forms both of north and south. Hymns, sometimes in mixed Latin and Provencal, sometimes entirely in the latter, are found early. A single prose monument remains in the shape of a fragmentary translation of the Gospel of St. John. But by far the most important example of this period is the _Boethius_. The poem, as we have it, extends to 238 decasyllabic verses arranged on the fashion of a Chanson de Geste, and dates from the eleventh century, or at latest from the beginning of the twelfth, but is thought to be a rehandling of another poem which may have been written nearly two centuries earlier. The narrative part of the work is a mere introduction, the bulk of it consisting of moral reflections taken from the _De Consolatione_. [Sidenote: Second Period.] It is only in the second period that Provencal literature becomes of real importance. The stimulus which brought it to perfection has been generally taken to be that of the crusades, aided by the great development of peaceful civilisation at home which Provence and Languedoc then saw. The spirit of chivalry rose and was diffused all over Europe at this time, and in some of its aspects it received a greater welcome in Provence than anywhere else. For the mystical, the adventurous, and other sides of the chivalrous character, we must look to the North, and especially to the Arthurian legends, and the Romans d'Aventures which they influenced. But, for what has been well called 'la passion souveraine, aveugle, idolatre, qui eclipse tous les autres sentiments, qui dedaigne tous les devoirs, qui se moque de l'enfer et du ciel, qui absorbe et possede l'ame entiere[50],' we must come to the literature of the south of France. Passion is indeed not the only motive of the Troubadours, but it is their favourite motive, and their most successful. The connection of this predominant instinct with the elaborate and unmatched attention to form which characterises them is a psychological question very interesting to discuss, but hardly suitable to these pages. It is sufficient here to say that these various motives and influences produced the Troubadours and their literature. This literature was chiefly lyrical in form, but also included many other kinds, of which a short account may be given.
