Raynouard wrote other plays, one of which, Les États de Blois (acted 1810), offended Napoleon by its freedom of speech. Realizing that the public taste had changed and that Romanticism would triumph, Raynouard abandoned the stage and devoted himself to linguistic studies. His researches into Provençal were to an extent inaccurate, but his enthusiasm and perseverance opened the way for the study of the subject.
