Maurice Denis was a French painter, decorative artist, and writer. An important figure in the transitional period between impressionism and modern art, he is associated with Les Nabis, symbolism, and later neo-classicism. His theories contributed to the foundations of cubism, fauvism, and abstract art. Following the First World War, he founded the Ateliers d'Art Sacré, decorated the interiors of churches, and worked for a revival of religious art.

Nicolas Poussin was a French painter who was a leading painter of the classical French Baroque style, although he spent most of his working life in Rome. Most of his works were on religious and mythological subjects painted for a small group of Italian and French collectors. He returned to Paris for a brief period to serve as First Painter to the King under Louis XIII and Cardinal Richelieu, but soon returned to Rome and resumed his more traditional themes. In his later years he gave growing prominence to the landscape in his paintings. His work is characterized by clarity, logic, and order, and favors line over color. Until the 20th century he remained a major inspiration for such classically-oriented artists as Jacques-Louis David, Jean-Auguste-Dominique Ingres and Paul Cézanne.
