The revolution of July, which put his friends in power, opened to him the career of higher education. In 1830 he became professor of foreign literature at the Sorbonne. The "Histoire de la Gaule méridionale sous la domination des conquerants germains" (4 vols., 1836) was the only completed section of a general history of southern France which he had projected. In 1836 he was elected a member of the Academy of Inscriptions, and in 1837 he published (with an introduction the conclusions of which would not now all be endorsed) a translation of a Provençal poem on the Albigensian war. After his death his friend Mary Clarke (afterwards Madame J. Möhl) published his "Histoire de la poésie provençale" (3 vols., 1846)--his lectures for 1831-1832. Fauriel had a preconceived and somewhat fanciful theory that Provence was the cradle of the "chansons de geste" and even of the Round Table romances; but he gave a great stimulus to the scientific study of Old French and Provençal. "Dante et les engines de la langue et de la littérature italiennes" (2 vols.) was published in 1854.
