The 16th century in France was a remarkable period of literary creation (the language of this period is called Middle French). The use of the printing press (aiding the diffusion of works by ancient Latin and Greek authors; the printing press was introduced in 1470 in Paris, and in 1473 in Lyon), the development of Renaissance humanism and Neoplatonism, and the discovery (through the wars in Italy and through Henry II’s marriage with Catherine de' Medici) of the cultivated refinement of the Italian courts (Baldassare Castiglione’s book "The Courtier" was also particularly important in this respect) would profoundly modify the French literary landscape and the mental outlook (or "mentalité") of the period. There is a slow evolution from the rude warrior class to a cultivated noble class (giving rise to the idea of the "honnête homme" in the 17th century). In all genres, there is a great interest in love (both physical and Platonic) and in psychological and moral analysis.
