In my project, I analyze the writings of 17th-century French libertines with the aim of understanding the expression of libertine thought and the imagination of the period, as well as highlighting the circularity of ideas among the analyzed sources. More specifically, my focus of study is the small core of four writers who were disciples of Pierre Gassendi, namely Cyrano de Bergerac, Tristan L’Hermite, Chapelle, and Charles Dassoucy. Upon examining their works, specifically Les États et empires de la Lune et du Soleil, Le Page disgracié, Voyage de Chapelle et de Bachaumont, and Les Aventures de Monsieur Dassoucy, the presence of common themes and ideas becomes apparent, including the advocacy for freedom of thought and imagination, criticism of mores and religion, and an emphasis on the idea of living well to enjoy earthly life.
