verse romances survive from the period 1150–1220. From around 1200 on, the tendency was increasingly to write the romances in prose (many of the earlier verse romances were adapted into prose versions), although new verse romances continued to be written to the end of the 14th century. The most important romance of the 13th century is the Romance of the Rose, which breaks considerably from the conventions of the chivalric adventure story. Medieval French lyric poetry was indebted to the poetic and cultural traditions in Southern France and Provence—including Toulouse and the Aquitaine region—where langue d'oc was spoken (Occitan language); in their turn, the Provençal poets were greatly influenced by poetic traditions from the Hispano-Arab world. Lyric poets in Old French are called trouvères – etymologically the same word as the troubadours of Provençal or langue d'oc (from the verb trobar "to find, to invent"). By the late 13th century, the poetic tradition in France had begun to develop in ways that differed significantly from the troubadour poets, both in content and in the use of certain fixed forms. The new poetic (as well as musical: some of the earliest medieval music has lyrics composed in Old French by the earliest composers known by name) tendencies are apparent in the Roman de Fauvel in 1310 and 1314, a satire on abuses in the medieval church, filled with medieval motets, lais, rondeaux and other new secular forms of poetry and music (mostly anonymous, but with several pieces by Philippe de Vitry, who would coin the expression ars nova to distinguish the new musical practice from the music of the immediately preceding age). The best-known poet and composer of ars nova secular music and chansons of the incipient Middle French period was Guillaume de Machaut. Discussions about the origins of non-religious theater (théâtre profane) – both drama and farce—in the Middle Ages remain controversial, but the idea of a continuous popular tradition stemming from Latin comedy and tragedy to the 9th century seems unlikely. Most historians place the origin of medieval drama in the church's liturgical dialogues and "tropes". Mystery plays were eventually transferred from the monastery church to the chapter house or refectory hall and finally to the open air, and the vernacular was substituted for Latin. In the 12th century one finds the earliest extant passages in French appearing as refrains inserted into liturgical dramas in Latin, such as a
