French poet, essayist and playwright, Paul Claudel also had a diplomatic career. He was a towering force in French literature of the first half of the 20th century. His works derived their lyrical inspiration, their unity and scope, and their prophetic tone from his faith in God. He wrote among other famous plays "The Announcement to Mary" (L'annonce faite à Marie) and "The Break of Noon" (Partage de Midi). He was an atheist for a time, and he converted one Christmas Eve, while entering the Cathedral Notre Dame of Paris.
Claudel also wrote a famous poem to Mary.
