The book provides a thorough and systematic description of the syntax of Old Occitan. The syntactic properties of the medieval language are illustrated through a wealth of examples chosen from a variety of texts, literary as well as non-literary: the "Boeci", the "Chanson de Sainte-Foi d'Agen", the "Chartes", the "Vie de Sainte Enimie", "Flamenca", "Jaufréeacute;" and, above all, the poetry of the troubadoures. Conceived in accordance with traditional philological models, the work is easily accessible to scholars and students in the field of Occitan language and literature. This general presentation fills a long-standing lacuna in the bibliography of Occitan and, in a broader perspective, of Romance philology.
